Primer questions


I am trying to paint over dark wallpaper with a raised design.

I primed the walls. How many coats does it need?

If more than one, how long do I wait?

Thanks

What primer did you use? Normally one coat is enough. And curse you for painting over the paper in the first place

Thank you Chris

It is Zinsser Bulls eye Odorless

The wallpaper was brown and purple and gold! What was your beef with painting over the wallpaper?

Painting over wallpaper is bad because,
a) it looks bad.
b) it often fails, leaving you with a mess you have to remove anyway.

As for the primer. Zinsser Odorless has one of the worse hides of any oil based stain blocker I've ever seen. I was surprise to note this considering all the other Zinsser products I've used have good hide to them.

Yep, all the things that make a paint/primer stink are what make them good, for the most part. You should probably be OK inside with that stuff but on any bare wood, inside or out, go with the full strength stuff. If the oderless was just as strong as the stinky stuff, then there wouldn't be the stinky stuff.

It's just wrong. Anybody that works in the industry( and gets paid) will tell you the same thing. It is almost always better to work with the original wall.

The problem is that eventually the paste holding the wall paper on will begin to fail, and the result will be that the wallpaper will, very slowly, start to peel at the seams.

Wallpaper is a chore to remove at the best of times. Painting over it just makes it more of a chore. The layers of paint on the wallpaper impede the penetration of moisture through to the paste layer to re-emulsify it.

It's better to remove wallpaper before painting, and the reason isn't just "because". It's because painting over it just creates a chore that will be more difficult to do in the future.
