When you decide to paint a room the first thing that comes into mind is what types of colors are you thinking about? There’s all kinds and types of different to choose from, types of color, types of finish.
So you can choose from many types of different kind of paints but the first one that should be considered is for your prep work.
There are different kinds of primers that are used for different purposes. If you have an interior wall paint job that is in excellent condition and doesn’t have any marks on it or doesn’t need any plaster repairs then a regular basic latex primer should do.
I usually prime walls that are a large change in color, because the primer cost less than does the finish coat. If you have a large room that’s being painted with some darker color and it will take over gallon of paint to prime it then it makes sense to use up a cheaper gallon of primer , than to use the more expensive finish coat just to prime with. But if you’re using a color very similar or close to the color that’s on the interior wall now, then it is smarter to just put 2 finish coats on.
If you’re interior walls are clean from pen marks or stains but you have some drywall plaster repairs then you need to get a primer sealer that seals the repair spot so when the top coat is applied you will not be able to see a dull spot where the drywall repair was done.
If you have drywall that has graffiti on it such as pen marks or crayon then you should use a solvent-based or shellac-based primer. I have found that latex based sealer primers don’t work as well as solvent based primers. Some marks still bleed through water-based sealer primers even though they say that it won’t.
There are a couple different types of bases for these specialty primers, the first one that I use is a shellac-based sealer primer. This primer dries very quickly and you can paint over top of it within just a few minutes. The other one is a solvent-based primer that takes around half an hour if you buy quick dry.You can buy this product in either a can that you can dispense from and roll it on or even by a spray can and spray it on. Generally for a few spots I use a spray can is much more convenient and no cleanup.
Lastly if you have glossy walls and you’re not sure whether it has latex paint or oil based paint on the wall the best thing to do is prime it with either an oil based or a shellac-based primer sealer. This for sure will allow you to apply latex coats of paint over top of it without it coming off.
Toronto painters (Hollywood painting) always checks for good adhesion. The last thing that you want is for paint to start coming off easily if at all. Many times people will put latex paint over top of doors which have been painted with semigloss oil paints. This creates a problem because no matter what paint you put over top of paint which is coming off is a problem.
