Do You Have A Paint Problems Answer Guide Available

Painting the exterior of your home is one of the best ways to improve how it looks, to protect it from the weather, and to improve its overall value. However, it is also easy to make mistakes and encounter problems when painting that can ruin all of your good intentions.

If you know the problems you might come across beforehand, and, more importantly, the ways to fix them, you are already one step ahead. You may even come across a product or two that will mean you can paint your home in confidence, and enjoy the benefits for many years to come.

The main way to enjoy problem free painting is to ensure your exterior walls have been correctly prepared, and are ready for painting. This means removing all of the old paint, sanding back the wood, repairing damage and cracks, and using a primer if required.

If you follow these rules, you may find your paint job looks perfect, but there are still some problems that can happen – even if you think you have done everything right….

Exterior Paint Problems No.1: Mould And Mildew

If dark patches start to appear on your freshly painted exterior walls, it may be mould. This is especially the case if the area is away from sunlight and often gets wet.

In most cases, this is due to a mixture of low quality paint, a failure to prime, or you have painted over previous mould without removing it properly. But of course the main problem is a wall that is not dry, which has consequently retained moisture.

The best way to remove mould is to clean it off thoroughly with bleach, and to repaint the area once it is dry. You may wish to use a waterproof mould blocker to prevent the problem resurfacing at a later date.

Exterior Paint Problems No.2: Cracking And Flaking

This often happens when the paint has been applied to a surface that has not been prepared correctly. In many cases, the paint may have been applied to a damp wall, and when the paint dries, the outer surface dries faster than the wall surface, leading to cracking.

The loose paint can be removed with a scraper, and spots can be repainted. It is important to paint on a day that is not too hot, to slow down the rate at which the paint dries.

Worried about white patches on outside walls? Protecting your brickwork with a waterproof coating is the best way to prevent this from happening

Exterior Paint Problems No.3: Bubbling On The Surface

This is a similar issue to flaking and cracking but is more likely to be caused by painting on a wall that is not totally dry. The wet wall slows down the drying process compared to the surface of the paint that is exposed to the sun which dries much faster. The result? An unsightly bubble on the surface.

Painting on a cool day and ensuring the wall is completely dry should prevent this issue. The best way to fix it is to simply scrape away the paint, sand it back, and start again. To prevent patches, you may need to repaint the entire wall.

Exterior Paint Problems No.4: Dirty Walls

Poor quality paint can be a magnet for dirt and can leave your freshly painted walls looking dirty within a few weeks. The issue is caused by the paint absorbing the dirt rather than repelling it.

A power washer may be able to remove the dirt, but you may find that repainting with a higher quality paint will be a more long-lasting solution. Waterproof and glossy paints are less likely to experience dirt pickup.

Exterior Paint Problems No.5: Efflorescence (White Patches On Walls)

This often happens on masonry walls, and is the leaching of salt deposits from the bricks that leaves white patches on your walls. It is caused by water escaping through the masonry walls, bringing the salt deposits with it.

Coating your bricks with a waterproof coating is the best way to prevent this happening. Prevention includes: preventing direct water access to the walls by repairing downpipes, or clearing out gutters. You should also check for any holes or cracks between the bricks, and repaint where necessary.

Avoid fading paint problems from the outset by using the right paint for the exterior of your home; if you have a South facing property, a UV resistant paint is advised

Exterior Paint Problems No.6: Surfactant Leaching

If small droplets are forming on your freshly painted walls, it may be experiencing leaching of the surfactants within the paint. It can sometimes be brownish, and can look dirty and unattractive.

This is usually caused by the paint being exposed to mist or dew, or humid conditions during painting and drying. This upsets the way the paint cures, and leads to the surfactants being released from the paint, rather than staying within.

Painting in the right conditions, and onto dry walls is essential. If this happens to your paint, you can simply clean it off as it occurs. It isn’t usually a long term issue, but permanent staining can occur if you don’t wipe the walls regularly.

Exterior Paint Problems No.7: Paint Fading

Using the wrong type of paint for the conditions can lead to it starting to fade and lose its colour after a few short months. This happens if the paint is exposed to direct sunlight.

You can avoid it by using the right paint for the exterior of your home and the material being painted, and by using a UV resistant paint. If it has already started fading, the only solution is to repaint.

Exterior Paint Problems No.8: Paint Chalking

If your exterior walls are becoming chalky, with a powder forming on the surface, the result can be a dull and faded look that is a disappointment after all your hard work. There are a few reasons why this might happen, including choosing the wrong paint or a low-quality paint, using a highly pigmented paint, or painting too thickly, and not allowing it to dry between applications.

The only solution is to repaint following a jet wash to remove the chalky substances. Painting directly over the chalk will lead to adhesion problems. The use of a waterproof topcoat may also prove to be useful in preventing this issue.

Hydrophobic coatings are the quality paint that you are looking for-and will remain that way for many more years to come. The result? Fewer hours spent fixing issues, and more time enjoying your home. Perfect!

Paint Problems Solved With The Help Of Hydrophobic Paints

Prevention is always better than cure when it comes to D.I.Y jobs, such as painting. When it comes to your exterior walls, it is clear that damp and exposure to inclement weather can cause all kinds of problems on your walls, ruining all your hard work in the process.

Choosing a wall paint or coating that will both protect your walls from wetness, and offer a great looking result is paramount.

Hydrophobic paint is a great start. You can choose a coloured paint that is water resistant, and yet fully breathable to boot.

This paint will allow the moisture already in your walls to escape without causing the paint to bubble or crack and will prevent water from making its way into the walls in the future. This water resistance also means less dirt and grime as well.

A waterproof masonry coating is also a great idea. Being clear, you can still see the traditional good looks of your brickwork, but your walls will be protected.

Bricks are especially susceptible to water ingress, and coating them offers protection from both the outside and the inside of your home. If water seeps in, it can cause mould and mildew on your interior walls, as well as on the outside of your property.

Hydrophobic coatings are the quality paint that you are looking for, and will mean that the paint job you have completed will stand the test of time. The result? Less time fixing issues, and more time enjoying your home. Perfect!
