Sometimes during the painted drywall or plaster some inconvenience to those who did not find an explanation, and surely complicate the work arise. Usually due to poor surface preparation and paint application.
These are some of the questions we might encounter at work painting or immediately after drying the paint, try to answer:
Why are bubbles passing the roller?
In textured walls this is no problem, smooth walls can cause the surface remains not quite perfect. We recommend using a short nap roller, precisely because the long hair and sponge are causing these bubbles.
Why paint drips or runs down the wall?
This happens because the paint is too thin. Generally the material is ready to use, in the event that the wall has a lot of absorption is necessary to add only a little water, in the case of water-based paints obviously.
Why not cover paint?
The above case can be a cause, the paint is too dilute. Another reason may be that you are not carrying enough paint roller, so it often happens that applies consecutive hands without fully covering the previous color. Do not attempt to render the paint more than directed and respect the drying time between coats.
Why paint to dry it cracks?

To solve the problem should be removed which causes the stain. If you have already let’s try a hand painted faux painting (or synthetic enamel background) matte finish and once dried continue with the usual paint.
Why are there brush marks?
