White Paint

Painting large areas can take copious amounts of time as well as a lot of hard work. So there is nothing worse than letting it dry and coming back to flaking or paint damage. Here at Elevation Maintenance, we are going to tell you why does paint damage and flake, also how you may be able to prevent this in the future.

Why is paint damage caused?

There are many reasons to why your paint might not be finishing the way you want it to, but often the most obvious one is the preventative measures haven’t been taken beforehand to stop the paint from damaging in the future. There is nothing worse than spending your time painting a surface to come back to it flaking, cracked or bubbling so you may want to follow a couple of our steps to help it from happening to you.

Cracks

Cracking in the paint can often be one of the most frustrating as it can really affect the aesthetic of the paints finish. This is often caused by two main problems, you have either applied to many coats to the surface or the surface you are painting still has dirt on it. If you are wanting to apply a couple of coats to your desired surface, you need to ensure that the coats are fully dry before applying anymore. Often paint can appear dry to touch, but the coats underneath it are still wet. If too many wet coats underneath the paint don’t have sufficient airing time, it can cause cracks in the paint which if not repaired in time can cause a significant amount of damage and can often lead to flaking.

Crack Paint

Blistering and bubbles

Blistering occurs similar to cracks; it will often happen when you have painted a wet coat onto a damp coat underneath. Blistering means the top coat of paint comes away from the paintwork beneath it. In some cases, it might only be one layer, but more often than not you can experience several layers being affected by blistering. This usually happens if you haven’t given the paintwork underneath sufficient amounts of time to dry, the paint can find it hard to stick. It can sometimes be caused by damp surfaces, so if you are trying to apply paint in areas of your property that may be humid or more prone to condensation, it might not come together as well.

One of the best way to prevent this from happening is by getting industrial fans or dehumidifiers from ManoMano to draw the damp air away from the paint. Another option to think about is opening all the windows if it is a warm, dry day, as it will also help get rid of any excess moisture.

On site spraying services will often have to look out for local weather conditions to determine whether the weather is okay for them to carry out there spraying. One of the main reasons for paint to not stick to an exterior of a building is even though it may appear dry the materials are often damp deep within it. Here at Elevation Maintenance we always make our guys wait around 8 hours before carrying out any spraying jobs to ensure all materials are fully dry.

Bubbles are more likely to be caused by drier weather. If you experience a significant amount of sunshine and warmer weather the exterior of your building could be more prone to bubbling. We know it can be difficult to decide when is right to paint the exterior of your property, the perfect day would be a dry day rather than a warm day. The reason for this is that the warmer weather can often dry the outer layer making it appear dry when in reality the solvent chemical become trapped in the paint, which can cause bubbling.

Bubbling Paint

Flaking

The paint used on your exteriors are often called Masonry paints which are only designed to last a couple of years, however UV light can have a significant impact on your properties exterior. This is because UV lighting can attack the emulsifier in the paint which is the ingredient that holds each component together. If you live in a warmer part of the country and experience a large amount of sunlight you may witness flaking a lot more than the average person, this is why we think it may be more beneficial for you to get in touch with a coatings specialist as they use specialist paints.

Preperation

Before you go ahead with painting your desired surface you must ensure it has been sufficiently prepped; you want to minimise the risk of your paintwork flaking, blistering, bubbling or cracking. First of all, you are going to want to get a stiff brush that will act like a sander to remove any paint or dirt from the surface. With many exterior materials on your homes or office exteriors it can be exposed to fungal growth, if you need to give it a deep clean we recommend looking at Fungicidal wash by Sealants&ToolsDirect.

Remove all loose materials and fill any holes or cracks in the material as you will want to make the surface you are working with as smooth as possible not to mention as dirt free so the primer and paint can create an even surface. As previously mentioned if the weather suggests it could possibly rain or is very humid you may want to avoid painting in this weather.

Summary

We understand that when you have spent the time painting your exterior to come back to it with defects can be incredibly frustrating that why we recommend you take the time to clean all surfaces before going ahead with any painting. Many of these problems can also be avoided if you use a primer before applying any paint which can often be a step that is missed. If you are ever struggling with how to paint an exterior we recommend speaking to a cladding coatings specialist.
