When doing a building painting job, you should always remember that there are two kinds of paints, one water based and the oil based and if you don’t want to have a bad result then it is good to note that these paints cannot be combined. The paint will run or peel if the paint is water based and is applied on top of oil based products and in a similar fashion if there is water paint sitting on top of the surface, oil based products will not be able to penetrate the wood and it would never set.
Stains and varnishes and other oil based products are designed to sink inside the wood so you can easily determine if the product is oil based because you still see the wood grain and it makes the wood colored and is enhanced by them. Today there are non-transparent stains that are being used, they sink in the wood but give the appearance of paint by covering the surface, and it will be difficult to determine if the product is oil based or not.
Doing the goof off test helps determine if paint is water based or oil based because it can sometimes be difficult to determine which is which as they sometimes possess the same characteristics. Goof off removes latex (water based) paints easily, so you can determine if the paint is water based by rubbing goof off using a piece of rug and if it comes off easily then you know for sure that the paint is water based. You can buy a bottle of goof off at your local hardware store. To make sure that you are buying the right one, check if it says something about removing latex paint. Your goof off test should be done in an inconspicuous part of the wall. Sometimes you may need to test walls with paintings that are already peeling off but you can still apply the goof off test by making sure that it is the goof off that is actually removing the paint, then check if the paint bubbles or looks like melting.
Latex or water based paint is much easier to work with. Oil based paints have been commonly used in the past and this is evidenced by oil paints on old buildings that are still standing today. If you want to paint a building that is covered with solid oil based paint, then it needs to be coated with a primer first if you want to repaint it with latex paint. Since latex won’t stick to oil, when the primer bonds with the wall then that it the time when the wall can be painted with latex paint. Paint distributors will know what type of primer to deliver with your latex paint by simply describing what you are doing for your building painting project.What I Can Teach You About Options
