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. It is now more difficult to determine oil based products based on transparency because of the use of non-transparent stains which covers the wood surface and make it look like paint.
If you find it difficult to find out if the paint is oil based or water based since they often have the same characteristic, try the goof off test instead. Goof off can easily remove grease, markers, and latex or water based paints, so if you rub a rug with a bit of goof off and the paint starts coming off, the paint is water based. You can buy a bottle of goof off at your local hardware store. Goof off removes latex paint so when you buy from your local hardware store check the bottle to see if it is indicated that it removes latex paint. Your goof off test should be done in an inconspicuous part of the wall. If the wall painting is peeling before you apply the goof off then make sure that the goof off is actually removing the paint; it normally bubbles or looks like melting.
Latex or water based paints might be ideal for your project because it is easier to use. The more popular paints in the past were oil based and that is why you can almost be sure that if you see an old building, its paints are oil based. Coating a solid oil based painted wall with a primer will make it possible to repaint it with latex or water based paint. The primer can bond with the oil paint providing a surface where the latex paint can stick. If you inform your paint distributor that you are painting latex over oil based paints, they can tell what type of primer you need for this purpose.What Has Changed Recently With Options?
