Priming OLD plaster walls! What is the best?


Good Morning,

I am currently stripping 8 layers of wallpaper that I KNOW (my grandfathers house) goes back to 1950. The wallpaper is coming off better than I could have hoped for! My question is what to do after I have it all removed? Eventually I will be painting with Latex paint, wash with TSP, wash with clean water, prime, (what type/name primer do you suggest) and double coat. Will be using an egg shell finish. Everything said and done the walls will NOT be perfect, but I need to have at least light scrubbability. (4 and 2 year old grandsons)

Thank You

Priming OLD plaster walls! What is the best?


If you are about to paint a previously-wallpapered surface, just make sure the old paste is off - otherwise you'll have a rough surface that no paint or primer will hide. I gather you are not having problems removing the old paper but once you get down to the first layer, there may be paste remnants left on the wall; now fortunately, they use a cellulosic paste back then which is easily re-emulsified back to paste with soap and water. Use a stiff brush or a sponge, perhaps a scraper...

Then prime with the product you choose.

But you say 'old plaster' i.e. cement-based wall treatment that has old paint on top of it. What you would be looking for is a primer that makes the adhesion of the new paint uniform - you don't need a filler because there is already paint on there. So, given you have a smooth, clean surface to start with, scuff it up a bit with sandpaper and wash it with TSP. Then apply a good quality acrylic primer to make the subsequent layers of paint stick well, resist scuffing, are washable and 'jam-resistant'.

Like BMs "Fresh Start"...my favorite.

After removing the wallpaper clean the walls well with tsp making sure to get any wallpaper residue off. Make any repairs necessary to the walls. Apply a good fast drying oil base primer, I usually lightly screen sand the walls after I prime with a pole sander and drywall screen, then apply 2 coats of a 100% acrylic paint.
