How to Avoid Air Bubbles in Wall Paint
Having air bubbles in wall paint can be a huge problem. Not only does it not look good, it can also cause the paint to begin to peel sooner and when you go to repaint later on you will find that the surface is uneven and causes the new job to look bad as well. There are ways to avoid air bubbles in paint though. Here are a few tools and steps to help you through this process.
Step 1 - Prep The Area
The biggest reason why people experience air bubbles in their paint is because the wall that they are painting on was not prepped properly. First off all you need to make sure that everything that was on the wall is completely removed. this means that you must use a chemical stripper to get adhesive or wallpaper off. Dust the walls to make sure that they are free of debris and then you can use a cleaner with a wet rag and clean off the entire wall. Now that you can see if there are any bumps or areas of unevenness you can sand it down and then rinse it off again.
Step 2 - Prime
Now that you have made sure that everything is clean and ready to be primed you will want to prime the area you are painting. This is another reason why many people experience problems with air bubbles, because they are not using the correct primer. You will want to use a flat oil primer over a latex one. You can never paint right on drywall, you need to make sure that you are using a primer and a flat oil based one is the best when it comes to eliminating problems with air bubbles.Make sure that between coats of primer you let each dry completely and then before you paint you will want to wait longer than the time they tell you on the directions for the paint. While many people only wait a few hours between coats, to avoid the bubbles you will want to wait a day or two at least. Also, try to factor in the humidity and temperature and do it on block of days where it is low.
Step 3 - Painting
Now that you are painting there are a few precautions that you can take to avoid air bubbles. The first thing to do is to Use a clean roller. Many times if you do not have a new or clean roller, you will experience gaps while you are painting which runs into a problem with bubbles. Next you want to make sure you do not use too much paint at once because you will be rolling over the same spots and dripping and a coat that is too thick is prone to bubbles.
Now that you are finished painting you can let the area dry completely.
