Blistering Paint Causes And Solutions: 6 Fast Fixes

blistering paint causes and solutions

Discovering bubbles and blisters in your finished paintwork can be an incredibly disheartening moment; especially after having spent so long transforming the exterior of your home.

Thankfully, there are a number of blistering paint causes and solutions, that you can be on the look out for, to stop it happening again.

Giving your home a fresh coat of paint can completely change the exterior of your property. However, like all the most beneficial home improvements, if you miss out a step, the finished look will be less than perfect.

This is especially the case with painting, where there are a multitude of ways that the finished look can be compromised. Here are the main blistering paint causes and solutions, that are essential to know before painting…

The Causes of Blistering Paint

There are multiple reasons why paint may blister, with the majority of reasons surrounding how the paint was applied to the surface, and a lack of preparation in advance.

As exterior house painting requires substantial preparation to the walls, failing to prepare could mean that you end up with blisters and bubbles in the surface of your paint.

Painting a Surface That Is Damp

Wet surfaces are one of the main reasons why people seek out blistering paint causes and solutions. The surface of a wall should be completely dry whilst painting, and moisture shouldn’t be allowed to pass through the exterior walls.

This can also be an ongoing problem if there is no moisture protection on the walls.

Painting a Surface That Is Dirty

Dirty surfaces are the bane of many DIY painters. A clean and dirt-free surface is essential to achieving the perfect finish, but also to avoid blistering.

This includes mud and grime, as well as broken render, crumbling brick, and any oil or traffic pollution that has marked the walls.

The Paint Has Reacted Chemically

Bubbles and blistering in the paint, can occur when the top layer of fresh dries before the bottom layer. This is a common problem when paint is applied to a hot surface.

The gases in the paint will have no viable escape route, so they will cause the paint on top to expand outwards, creating very noticeable bubbles in the paintwork.

Seeing your new paintwork marked with blisters and bubbles, can be a terrible experience, that nobody wants to see repeated. With a bit of knowhow, and an investment in the right product and the right team, you can ensure that your paintwork is never less than perfect

Using the Wrong Kind of Paint

Not all paints are suitable for external painting. Even the right paints, when applied in the wrong places, can cause blistering problems.

The commonly used oil based and latex based paints, are generally suitable for exterior painting, but when oil is applied over latex, blistering can occur. The same doesn’t happen when latex is applied over oil.

Poor Conditions Before the Paint Has Dried

A source for many blistering paint causes and solutions queries, is poor conditions after painting.

If the area becomes damp, or gets exposed to a high humidity after painting, blisters could occur in the previously perfect paintwork.

The Solutions to Blistering Paint

Many of the common paint blistering problems can be solved with good surface preparation in advance.

However, if you want to achieve a guaranteed perfect finish, and avoid any problems with blistering paint causes and solutions, there are two fantastic options to choose from:

Option 1: Using a Professional Wall Coating to Protect Your Walls

Eliminating all the problems with the wrong paint type and inadequate preparation, is the use of a professional wall coating.

Very different to standard off the shelf paint, a wall coating goes that extra step to protect your home against the weather, dirt, and heat loss; saving you money on energy use, and the cost of repainting.

In terms of blistering prevention, a wall coating boasts superior hydrophobic properties, which means that the product doesn’t allow water to pass, but still lets the walls of a property breathe. By minimising the risk of weather damage, your paintwork will stay protected, along with your walls.

Option 2: Hiring a Team of Experts for the Perfect Finish

Combining a specialist wall coating, with an experienced team of professionals that know how to avoid blistering problems, is a recipe for success.
