Have you ever spent an extended period of time trying to get the perfect finish on your paintwork to find after a couple of months the paint damages and bubbles? We’re going to discuss with you why you get paint damage and potential ways to prevent this from happening in the future.
How is paint damage caused?
There is a range of factors that can potentially affect the way your paint finishes. These damages are more likely to have been caused by preventative measures not being taken beforehand. It can be incredibly frustrating to paint a surface to have it flake, bubble or crack later on, so there are a few things you need to know about how paint works and ways of preparing if you come across this issue.
Blistering and bubbles
Blistering is what happens when the top coat of pain comes away from the coat beneath it. The paint can sometimes be one layer, or it can be a couple the same way a paint stripper works. This is one of those situations you are most unlikely to predict and can be challenging to prepare for. If you paint onto a damp surface, this type of damage is more likely to happen as it cannot set how it would on a dry surface. You might find it more apparent in areas of your home or office that are more humid. The best way to prevent this from happening is to get yourself industrial fans or dehumidifiers; this will help dry out as much moisture as possible. If need help with choosing the right dehumidifier Tool Station have a range of different options suitable for both domestic and commercial use.
If you are thinking about painting the exterior of a building, we always recommend that you take a look at the weather before doing so. Blistering occurs when the item your painting has moisture within it, it works the same way if its likely to rain after painting the exterior of a building. We suggest that you leave it around 8 hours after it has rained to apply a coat of paint.
Bubbles can also be formed in warm weather; we know its hard to find the perfect time to paint your exterior. However, if you are painting multiple layers, the heat can dry the outer layer a lot quicker than the layer beneath it causing the solvent chemicals to become trapped in the paint.
Cracked paint can also be caused by a number of issues, most likely down to two, either there are too many coats applied or the surface in which paint had been applied to was dirty. When applying more than one coat, you should always ensure that the previous coat has fully dried otherwise it can lead to cracking in the paintwork. Cracks can, in fact, start small but if not repaired in time you could be looking at a more significant issue, they can worsen and often lead to flaking.
Standard masonry paint is usually only designed to last a certain amount of years; ultraviolet light can significantly affect the paint on the exterior of your home or office building. The UV light attacks the emulsifier within the paint, this is the ingredient that holds all other components together. If you are living in an area where you experience a lot of sunshine or warm weather your best bet is to speak to a specialist coating company, the paint that they use is a lot stronger then those customers can purchase.
You must ensure that your surface area is clean and dry before applying anything to it. Use a stiff bristled hand brush to remove any dirt that won’t budge. If you find the wall is filthy, we recommend to wash the wall with household detergent and rinse well with water after. If you are experience mould you can purchase fungicidal wash to help remove it, you can buy it from Sealants & Tools Direct. You will then need to fill any small cracks and holes; you will want to make sure that the surface area you are prepping has no loose materials that primer and paint can stick to causing an uneven surface. Painting in hot or humid conditions should be avoided if at all possible. If your paint requires a primer, then you should be applying it as specified by the manufacturer.
If you have permission to put up scaffolding, it could make your life a lot easier and less dangerous compared to using ladders. Most commercial business should have the right tools to carry out a painting job however if you a domestic painter you may want to get in touch with your local tool hire company, not only can they give you advise on the best tools to use but you don’t have to purchase and store them.
You will need to make sure that the area with bubbles hasn’t been affected by any moisture or been overly exposed to heat. If you are experiencing bubbling of blistering in your paint, then we recommend scraping the paint until you have a firm edge, feather lightly with abrasive paper. You will find that bubbles on a painted surface are typically localised, so you won’t have to remove large amounts of paint. Using a primer after sanding will allow the paint to stick to the area you want it to, be sure to apply enough prime otherwise you could experience bubbling again.
