How to Deal With Common Paint Problems

House painting can be done by any homeowner and DIY’er – or by hiring a great local painting expert. However, doing it properly is not as easy. Without necessary precautions and proper preparation, problems may surface sooner than you think. To prevent such paint problems, or in many cases, deal with them, here are the best ways to do it.


When you apply paint that is too thick, the paint underneath will dry more slowly than the top film. This causes wrinkles as the surface dries and swells while the paint underneath is still wet. To correct this, let the paint dry completely and then sand the surface smooth. Recoat with paint that is properly thinned under good weather condition, ideally at a temperature of above 50°F.


This is caused when the finishing coat has been applied before the primer or the undercoats have completely dried. It is also caused by using primers and paints that are not compatible, thus the poor adhesion. The result is usually that of a hide of an alligator where islands of paint show the previous surface. To augment this, scrape the old paint, sand the surface, apply a compatible primer and then repaint.


When paint forms bubbles or blisters, this is usually caused by pressure from vapor or moisture beneath the paint film. To correct this problem, scrape off the blisters and check if the wood underneath is wet or dry. If it is dry, then the cause is moisture or that it was painted in hot weather. Repair any damage on the surface, sand, prime and repaint.


This is often caused by painting over a wet surface. The moisture from the wet wood, for instance, pushes the paint out, resulting in peeling paint. Another cause you should look out for is when you paint on a dirty or glossy surface. So before painting, scrape all the flakes and imperfections and sand the surface smooth, then apply primer and paint.


Most cheap paint, when applied heavily or in high humidity, will dry slowly and remain tacky for a long time. Poor formulations can cause this effect so you might want to buy high-quality paints instead to ensure a smooth and durable finish.


When paint has a dusty surface, especially with outdoor paints, then chalking has occurred. This is ideal to wash down dirt when it rains, but may become problematic if the surface painted is too porous that it absorbs most of the paint’s binding agents. To solve this, wash the area down thoroughly using a chalk cleaner and then repaint with nonchalking paint.
