Do You Have Your Appointment With The Paint Doctor?

Why Is Painting Your House Important?

Making your interior and exterior look appealing is something which can add new life into your house.

Regardless of whether you plan on selling your house or not, a new paint job adds value, while also making it look as presentable as possible.

Where other wall painting contractors will fix or improve your exterior for the short term, they are actually harming your wallet in the long term.

Roof painting companies and diligent paint service providers, such as Paint Doctor, who use high-quality products, will ensure that your exterior paint lasts for many years.

Paint manufacturing companies, who do their homework, are able to deliver a product which is not only effective and durable but also something which is not an environmentally harmful commodity.

By refurbishing parts of the space, as well as removing any unnecessary and unwanted issues, the wall painting and roof painting company are thorough in their approach.

Alongside this, Paint Doctor is also a wall painting contractor, and want to improve your internal and external features, which will help in making your home look presentable.

Being a paint manufacturing company means that Paint Doctor is able to make a difference in the environmental impact of their products. Going Green in any colour you want.

Only The Best

Paint Doctor only wants to supply your house with the best. The best quality products with the best service possible.

Using the best products will not only ensure that your house looks top quality but the amount of protection this top-notch paint provides guarantees that the roof painting company wants to keep the maintenance for your roof and walls low.

What this means is that as a paint manufacturing company, Paint Doctor wants to deliver a service which is able to withstand the forces of nature.

What does it mean to use only high-quality products? What it means is that your wall painting contractor, in the form of Paint Doctor, is using products which are long-lasting and while being of high calibre, are also not overrated or overpriced.

Having to get your house a paint job is something which takes a lot of planning and is a long process. After using Paint Doctor, your house won’t have to be painted for a number of years.

Paint Doctor’s Procedure

Experience mixed with due diligence is a combination which certifies Paint Doctor’s passion in giving you the best standard of roof and wall painting possible.

Roof painting companies are able to provide you with a new paint job, but Paint Doctor is able to assure you that the quality of their service is focused on providing you with paint which endures all of the seasons, and will come out looking as fresh as the day it was put on.

Paint Doctor is a wall painting contractor which has streamlined their service, providing each and every home with the same high-quality services for all of their clients.

Being serious about service, Paint Doctor will assess the current situation of your wall or roof. After this, the paint manufacturing company will be able to issue your house with the best possible service, with an approach that serves your house specifically.

The services available are a pre-paint hydro wash, repairing of any cracks, coating windows, plastering and damp proofing, scaffolding, sealing, painting and inspections.

Hydro Wash

The use of high-pressure water power allows for the removal of loose paint, mould, dirt, mud, bird droppings, among other things, to be removed from a wall or any other service.

Paint Doctor is able to use hydro wash in order to remove such things which makes the cleaning process, pre-paint job, much easier.

The wall painting contractor believes that removing as much of the existing paint as possible, as well as any extra filth, makes the painting process much more effective and less time-consuming.

Cracks

Painting over cracks is an inefficient use of paint and time, as the cracks will ultimately ruin the hard work of our service and increase the maintenance you’ll have to do.

Paint Doctor is not just supplying wall or roof painting, they are providing high-quality services which will be worth every penny.

Using a patching composite or re-plastering agent will help in repairing the cracks on your house, and will go a long way in improving the aesthetic and giving your house that extra bit of pizazz.

 

Window Sills

Window sills are a very important feature for the exterior of your home. As such, Paint Doctor provides a paint job which matches your wall or roof for your window sill, adding another layer in making your house look and feel distinctive.

Any other items or features of your home will be covered to ensure that any dripping paint does not ruin them.

Damp Doctor

A paint manufacturing company, Paint Doctor has also designed their own product which deals with areas where there are damp spots or larger damp areas.

What it does is remove the water from the area, which lets clean and clear air into space, and allows for the overall area and water to be improved, meaning that the condition of the space is enhanced.

The product is able to guarantee the decrease in the time the dampness spreads so that it does not affect the paint coating which has been applied.

Damp Doctor is another tool used to make certain that the wall painting is going to last for a very long time, protecting the time, effort and money from Paint Doctor and their clients.

The Roof

Just like the wall, roof painting companies like Paint Doctor must assess the roof, to see if any pre-maintenance needs to be done before applying any new form of paint.

The intention for doing such assessments is to decrease the level of maintenance or upkeep you will have to do in the future.

Any and all rusted parts must be properly washed and tended to with treatments. Using a primer such as rust converter paint will definitely tend to the rust filled spaces.

If the rusted parts are too far gone, then Paint Doctor will need to replace the metal roof by placing new metal sheets above the damaged spaces.

The roof screws will be analysed in order to see if they must be replaced as well.

Weak or missing screws will also be replaced by Paint Doctor as this is not only a concern for them during their service but definitely for you.

In case of any unforeseen mishaps in the future, the roof painting service will secure the metal sheets as mentioned above, which can prevent such things as leaks from occurring.

Paint Doctor has been able to provide their main roof painting and wall painting services, while also providing additional services, which is a huge benefit as you can rely on one company to do everything that’s required.

Building onto this, all of the services given by Paint Doctor are all at an affordable price, and is serviced in a professional and faultless way.

Going Green

 

The environment is in a bad state at this point in time. There are businesses who have the resources and the platform to make a change and are working hard to do so.

Paint Doctor is no different, researching new and improved ways to help in innovating paint which does not contain as much of the harmful components as in the past.

Paint has been something which has evolved over the years as lead, which caused lead poisoning, was used in paint for a number of years.

However, there is still room for improvement and paint manufacturing companies, including Paint Doctor, have been working on decreasing their footprint, while helping you be a part of a healthy and beneficial movement.

Paint Doctor has vowed to try this hardest to make not only Johannesburg a progressive and influential place, helping with environmental issues, but entire South Africa

Paint manufacturing is not an easy job to do. By making it your mission to design and develop paint which is as eco-friendly and as effective as possible is adding even more pressure.

Paint Doctor understood this, and took time out of their day, applying themselves by trying to understand the jigsaw puzzle which is paint. They were able to create state of the art paint which is as high quality in its use as it is as high quality in its decrease in environmental impact

The wall painting and roof painting company is also aware that by finding suppliers for their other products, who are also high in rating in terms of decreasing environmental impact, they are moving their entire company into a Green state of the application.

Painting Companies Johannesburg

Choosing the right company to professionally paint your home.

Painting your home is time-consuming and a lot of patience is required, why not have a professional company come in and do the job from start to finish to eliminate that stress in your life. We talk about questions to ask a painting company, what happens if you don’t use a primer before painting and what you should know before painting your home.

What questions do I ask a professional painting company?

Do you have referrals and a list of customers willing to verify your quality of work? In what way will my house be prepped for painting? What type and grade of paint will be used? Will you be using primer? What is your turnaround time? What do you charge to paint the entire house with all the materials? Asking these questions will give you a clear view before you give the go ahead.

What happens if you don’t use primer before painting?

Dry wall primer helps the paint adhere properly as it has a glue-like base. The proper paint adhesive should be used before painting. Priming is essential to avoid the peeling and chipping of paint, especially in very humid conditions. Failure to use primer will result in bad conditions in the long term.

What should you know before painting your home?

What type of paints attract dirt more than others, which paint colours fade quicker than others? You need to consider mother nature, using the correct primer and prep work. What materials you need for the job and how many coats of paint is required.

Eco-friendly paint

‘Green’ Paint in any Colour

As we steadily move through the twenty-first century, humankind is becoming increasingly aware of our impact on the environment.

While it might often seem like our efforts to combat it are just a drop in the ocean, we have already started seeing the positive results of simply being a little more mindful of our carbon footprints. This extends to all activities and areas of interest, and the simple act of painting a house is no different.

The type of paint you use can have an impact on the environment, which is why many paint stores the world over are offering solutions that offer the quality of lead or solvent-based paints, while having much less of a negative impact on the environment.

Looking for a paint that meets these standards? Here are a few things to look out for:

Know What’s in the Tin

It may sound strange, but it does happen that paint manufacturers don’t always list their ingredients in full, on the tin. Check every label before you buy anything, and if there is no indication of what chemicals make up the ingredients, put it back down and look for one that does, and clearly states a mixture of organic ingredients.

Volatile Organic Compounds

Volatile organic compounds are those that have a high vapour pressure at room temperature, and examples include benzene, formaldehyde and methylene (to name a few).

These substances are commonly in solvent-based paints and are not only bad for the environment, but also pose health risks to people and produce a paint product that releases dangerous fumes when used.

Water Based or Solvent Based

Select water-based paints over solvent ones and you will get the greener, less destructive option. To check which one you are buying, take a look at the instructions on how to clean the brushes. If they require benzene or any other clear spirits for cleaning, they are solvent-based. Water-based paints only require warm water and soap to be removed from brushes.

Contact Paint Doctor for a Greener Option

Tips for Painting Your Little One’s Nursery Room

Painting your baby’s nursery room is an important part of preparing to become a parent. In fact, the process is called ‘nesting’ and it can help you to bond with your baby long before their arrival. Getting creative and having fun is a great way to approach this, but here are some important tips that might help to guide you along the way.

A Strong Finish is a Great Start

Paint comes in a variety of finishes which can make the painting process that much more confusing. Matte looks amazing and bespoke, but the practicalities of having it in a nursery room may sway your decision. Matte is not an easy surface to wipe and may mean you have to touch up the paint job regularly. An eggshell finish has the least amount of sheen after matte, with a surface that can be easily wiped.

Go Green

No, we don’t mean go green in colour – unless you want to, in which case, we are all for the vibrancy! Going green means selecting paints with fewer to no toxic compounds so that your baby is in the safest environment possible, while you are helping the environment at large too. To do this, look for paints that have no volatile organic compounds (VOCs) which emit little to no toxic solvents. To be on the (even) safer side, make sure that the room has plenty of time to aerate before your little one is brought to their new sanctuary.

Colour

Speaking of colour, this is where it gets really fun! Start by picking a theme that you like and choosing colours which can bring out the best elements of that theme. Painting test patches on the wall is a great way to see which colours will work best in the particular space. There are really no rules here, but be mindful of whether or not you want something bold and bright or a more neutral palette that can work well with other elements of the nursery. The most important thing? Having fun…

The Best Paint for You and Your Baby

If you are a bona fide DIY guru, then sourcing quality paint with no organic compounds should be one of your top priorities. If you are not so DIY savvy, you can never go wrong with a professional paint job from a reputable paint store. The team at Paint Doctor can provide you with both and ensure that your little one has an amazing space to come home to. Contact their team or visit their website for more information.

Time to Repaint?

The durability of paint varies based on the quality of paint, the efficiency of the paint job itself as well as the climate and location that you are situated in. Coastal homes, for example, may needed to be repainted more regularly as the exterior is more frequently exposed to sand, wind, salty air and sun. Paint likes to tell stories, so look out for these signs that a new paint job is in order;

Faded Paint

Also known as photodegradation, recurrent exposure to the elements (particularly UV light stemming from the sun) changes the composition of the pigments in the paint. Those changes result in a decreased vibrancy and colour intensity. Often, areas that deal with more intense exposure are affected worse than other areas, which makes for an unsightly comparison. If you see faded areas or an overall fade and loss of colour intensity, it is definitely time to repaint those walls!

Blistering Paint

Blistering paint occurs when the top layer of paint separates from the coatings underneath it. Moisture is normally the culprit, so surfaces need to be dried and prepared accordingly to prevent bubbling. Without the necessary precautions having been taken, any paint finish has the capacity to blister and create bubbles.

Latex and acrylic paint are particularly prone to this, so it is important to have the paint job done professionally and to source paint from reputable paint manufacturers – particularly in a place like Johannesburg where we get frequent bouts of rain in the Summer season.

Chalky Paint

UV light is the usual suspect again for paint that is emanating a chalky residue. The UV rays weaken the binders in the paint, leaving pockets for the pigment to escape. Sometimes, the binders react when in contact with oxygen which results in a response known as oxidation. Oxidation has the same effect on paint that the UV rays do.

The Ticking of Time

All paint jobs need to be redone once the decay of time has struck. With that being said, quality paint and a vast understanding of its application goes a long way to lengthen the distance between maintenance periods. If it’s time to repaint, make it look better and last longer by contacting the team at Paint Doctor, or visiting their website for more information.

Finishing Strong

There are five paint finishes to consider when selecting paint for your walls. High gloss offers a shinier surface and higher resilience that is great for bathrooms and kitchens. An eggshell finish provides a more matte-based look, well-suited for lounges and dining rooms while the go to in-between finishes that will offer the best of both worlds include satin and semi-gloss.

The Importance of Exterior Painting

Year after year, the seasons change, and your homes exterior surfaces are exposed to its worse enemies; moisture and sunlight. These two elements will continue to cost money if you do not have a preventative maintenance plan in place.

The problem with moisture and sunlight is that when a surface is painted, the paint film is resistant to water contact from dew and rain. The problem occurs when moisture gets in between the pain film and the surface. The pain film then weakens and it loses its gloss. The cold of winter and heat of summer will make the wall surfaces expand and contract. A quality paint film is going to withstand these changes in in temperature because of its flexibility properties.

Below are some of the most common problems that arise on the exterior of your home:

Alligatoring

Alligatoring is patterned cracking in the paint film which resembles the scales of an alligator.

Blistering

Blistering are bubbles that result from localized loss of adhesion and the lifting of paint film from the underlying surface.

Chalking

Chalking is the formation of very fine powder on the surface of paint film during the weathering process, this can cause color fading as well.

Flaking / Cracking

Flaking or cracking is when the dry paint film splits through at least one coat, this will lead to the complete failure of the paint.

Efflorescence

Efflorescence is often seen as a white fluffy deposit of salty crystals on any cementitious walls. It will also depend on the presence of moisture and salt.

Fading

Fading refers to the excessive or premature fading of the paint color, it will often occur on the exterior surfaces that face western and southern exposures.

Algae and Mildew

Algae and mildew are gray, black or brown areas or spots that are found on the paint film or caulk bead.

Peeling

Peeling is when the coating or paint lifts from the surface because of poor adhesion. This may involve one or more coats.

Tannin Staining

Tannin staining is a tan or brownish discoloration that appears on the paint surface because of the wood tannins migrating from the substrate through the paint film.

Water Based Paint Problems and Solutions Pt 2 Snail Trails & Touch Ups

This week, we carry on with specific paint problems that are particular to the south african climate. In this article we will teach you how to remedy badly done touch up jobs, and snail trails

Touch Ups..

Description

Areas of different colour with signs of application directionality and or texture

Causes..

  • A poorly colour matched paint was used.
  • The touch-up coat was applied at different temperature – this can cause it to be lighter or darker than your last finish coat
  • Sun exposure may have caused the applied paint to fade slightly.
  • the original retained paint was used , while the existing in-situ coating has faded.
  • The touch up paint was stored for a prolonged period of time and has degraded or colour developed.
  • Failure to reduce the touch-up paint by up to 25%.
  • Touching up marks that could be removed by washing with a sponge and liquid detergent.
  • The touch-up coat was applied to a porous surface – porous surfaces give problems especially with high-sheen eggshells and higher gloss finishes because unprimed porous substrates absorb more of the paint they leave less of a sheen or gloss.
  • A different type or batch of paint was used – different paint types require different amounts of time to finish. the amount of time between the application of your finish coat and touch-up can affect how well these two coats blend together.
  • An application technique different to the original one was used from the e.g. Touching up with a brush when the original coat was applied by roller.

Preventions and Remedies

How to prevent touch up problems                                       

Prevention, is always better than cure as they say..

So here are 5 easy tips to prevent future touch up problems..

  • Always use the same batch number when available
  • Try to wash the mark off first with a sponge and liquid detergent.
  • Use only enough paint to cover the mark, excess paint may cause a halo.
  • Use a feathering-in technique, avoid dabbing.
  • Thin paint up to 25%.

How to remedy touch up problems

Fortunately, the cure (in this case) is much simpler than the sickness. All you have to do is match your colour coating to the existing colour, and then recoat the entire area from edge to edge/ corner to corner. Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.

 

 

Snail Trail

Description

Snail trails are shiny vertical run-marks seen on dry paint films, they are predominantly seen on matt coatings but can also be seen with some sheen coatings. Streaks generally start to emanate from flat topped walls or parapet walls. They are usually randomly spaced and follow gravitational direction. Although snail trails look like dirt streaks, they are not the same.

Causes

Snail trails happen when the water soluble paint components have been washed away by water. Dry paint films are made up of pigment and binder, but to present the paint in a usable form, many additives are used in the formulation.These additives are mostly water-soluble and remain in the dry paint film until they are effectively washed out by water – be it via rain, dew or by irrigation sprinklers. If the amount of water falling on the surface is low, then only part of the water-solubles are washed out, and they can dry on the surface. This leaves what we call snail-trails. They tend to be sticky, and can act as a dirt trap. This could have occurred within the first 2 – 24 hours depending on the  humidity and dampness experienced during the time of painting, or in rooms of high humidity eg kitchens, bathrooms and showers etc

Preventions and Remedies

  • Avoid painting in adverse weather conditions. eg late afternoon if cool damp conditions are expected in the evening or overnight.
  • If the problem occurs in the first day or two it can usually be rinsed off rather easily, with a damp cloth, soap and water. Problem may occur once or twice again before leachable material is completely removed. When paint is applied in a bathroom, it is helpful to have it dry thoroughly before using the shower. Remove all staining before repainting.
  • Fortunately, more difficult trails weather away within the first 3-6 months or are washed from the film after 2-3 rains. Snail trailing should not affect the ultimate durability of the coating.
  • If none of the above works, recoat taking care to consider touch-up batch variation, difference in application technique etc.

Water Based Paint Problems and Solutions Pt 1 Chalk & Algae

South African has a very unique climate; therefore there are certain paint problems that are specific to it. In, the next few articles we will address some of these problems and how to remedy them. In this article we will start with problems chalk and algae.

Fungus/Algae

Possible Causes..

  • Algae can grow on surfaces that are continually damp and dirty and receive no sunlight.
  • Insufficient fungicide/ algaecide in the paint can also worsen the situation.
  • Areas that have had previous mould, may have also been painted over.
  • Reusing opened containers that have received contamination from application transfer and or storage conditions.
  • failure to prime a bare wood surface before painting.

Solutions..

  • to distinguish, firstly if the contaminant is fungus/algae or dirt, drop a few drops of household bleach onto the designated area and see if the discoloured areas disappears. if it does then it’s probably fungus/algae.
  • check for any sources of moisture eg leaks, sealing or ventilation. Fix them.
  • apply a surface sterilizer/fungicidal wash (a diluted household bleach solution – 1 part bleach>3 parts water can also be used) Leaving on for 20 minutes, applying more as it dries. Then scrub and rinse thoroughly. Remember to wear rubber gloves and eye protection while doing so.
  • High pressure washing is a solution to fungus/algae (remember to rinse and residue and allow to dry again before applying any recommended paint)
  • prime the surface with a water based primer.
  • apply a premium exterior water based paint that is protected with a dry film biocide.

Chalking

Description

Chalking is the formation of a white, chalky powder on the surface of a weathered coating, it happens when the binder within the paint is broken down periodically due to weather conditions, UV rays and moisture exposure, the binder then releases the pigment articles within the paint, what you see as the white chalky power is consequently the broken down binder and released pigment particles. Nearly all paints will show some evidence of chalking over time, when they are subject to outdoor exposure. This slow erosion is much more preferable than cracking or flaking and once the chalk is removed the area is desirable again for painting.

You can identify chalking by rubbing the surface of the affected area with a damp cloth (or even dragging your hand) which results in a light deposit to the cloth and the restoration of the colour to the cleaned surface.

excessive chalking is not desired, because it can run down onto the underlying structure and deface the appearance of the surface. It can lighten the colour of your paint or erode your paint film resulting in a loss of protection to the substrate.

Possible causes..

  • using an interior paint quality for outdoors use ie enamel paints or lower gloss level acrylics.
  • poor surface preparation and a failure to remove the poorly bound surface before painting – paint needs to adhere to a sound surface.
  • Using a low grade paint comprising of a low binder and high pigment loading.
  • use of an interior paint for an exterior application.
  • not adequately sealing a porous surface.
  • spreading a coat too thin.
  • nearly all paints will show chalking over time as subjected to outdoor exposure – most south african medium quality paints are in the medium to high PVC range, and chalking can be expected within 3-4 years.

Solutions..

Chalk needs to be removed before repainting – it is is in the same category as dust or dirt.

  • Rub the painted surface with a finger or dark cloth to determine the degree of chalking.
  • high pressure cleaning is a common surface preparation method, and can be used to clean chalking.
  • scrub with a stiff brush . Rinse thoroughly and allow to dry. Rub the surface with your finger to see if any chalk residue remains. Repeat the cleaning process if powder is still present. If chalk persists, recoat with Alkali Resistant/plaster Primer or Bonding Liquid and coat with appropriate quality top coat. If little or no chalk remains, and the old paint is in good condition, then no priming is necessary.
