Painting Fun!


Im doing a total paint job on the house.

Some walls are new/fresh drywall and others are a mix of either latex or oil based paints. I haven't tested yet but im assuming if she cover paint with wallpaper it must be really old.

First thing: doesn't anybody recommend the best method to proceed with this? I have heard to sand the painted surfaces so they can take the primer better and others have said buy an all in one Primer and Sealer (Behr from Home Depot has this product). Thoughts?

Second thing: While the above is going on elsewhere there were a couple of walls with wall paper, I removed all of it then scrapped off that layer of glue pretty much clean. In spots though it is a little rough still. Should I sand it abit everywhere or try with a damp sponge to see if that remove more of it? I want to basically get this wall ready to be painted as well.

No need to just assume that the underlying paint is oil base. Oil base enamel in kitchens and bath fell out of favor in the 70s and 80s.

Unless all the wallpaper paste has been removed it's best to prime those walls with either an oil base primer or Zinnser's Gardz. An oil base primer is also best if switching from oil base enamel to latex paint [any sheen] Wallpaper adhesive is best removed with soap and water.

It never hurts to scuff sand to promote adhesion (be sure to remove the sanding dust). I believe primers and paints have different purposes and therefore putting both in the same product could only dilute each's effect. To that end, I use separate primers and paints. Additionally, one will typically find better supplies, equipment and advice in a paint store than in a paint department.
