Also, I've heard there's a way to check to see if old paint on a surface is latex or oil based. Does anyone know how to do this?How do I prepare a surface to use latex over oil base paint?
they sell primers that you can paint oil or water base paint over it. just read the labelHow do I prepare a surface to use latex over oil base paint?
To check which paint you are dealing with dab a q-tip in fingernail polish remover and rub a small area on your wall. If its Latex paint some of the paint will come off on the q-tip, if its Oil based paint nothing will happen.
If you are dealing with Oil based paint you will need to prep the walls by sanding them high grit sandpaper- but keep in mind you are not trying to remove the paint you are merely scuffing them up a bit to hold onto the primer better.
After you have finished sanding you will need to vacuum and wipe down the walls to remove all dust.
Once your walls are clean you will need to prime them- I would recommend Kilz, it offers great coverage and you can find it pretty much anywhere paint it sold.
After the primer is dry you can begin painting with your choice latex paint. Just keep in mind when your buying your paint that you will most likely have to apply two coats.
It may seem like alot but its really not that hard- just time consuming. Good Luck!!
