Caulk or Prime Drywall first?
 
I removed wallpaper from my bathroom that the builders of the home hung without first priming the drywall. I am going to paint the walls and want to know if I should first prime, then add caulk to the baseboards and around tub, shower and other areas in need and then paint OR should I prime and paint and add caulking? Any suggestions on what type of caulking to use?

I would repair the drywall, then prime and paint it.

I would then do my caulking. Use silicon in any wet areas, like between the tub and sink and anything else.

I would use a mildew resistant acrylic caulk every where else. Acrylic caulks are easy to remove with strong solvents like lacquer thinner or acetone (which is typically what nail polish remover is made of).

Drywall
Caulk - Use latex caulk. Tub area: Use latex with Silicone added (paintable)
Prime
Paint

The recommended method is to prime then caulk. Then paint. Use the siliconized caulk so you can cut in on it.

Wallpaper primer is called sizing. Available anywhere wallpaper is sold. Makes the paper easier to maneuver when you hang it and easier to strip when you don't want it any more.

sizing is not the actual paste/glue then? it has to dry first?

Gelineau:
Prime, Caulk, Paint

DangerMouse:
Prime, then size, then cover
If using a specialty primer like Zinsser's Shieldz Universal, there is no need to size


...BTW I miss your show terribly
Please let me know if it gets put back on the air
Thanks!

Thanks for all the info guys, I will start tackling this project tonight and hopefully be completely done by the end of the long weekend.

Sizing is what you use to provide a film for the glue to stick to, but not soak into your wall. If you don't size, you end up with a situation where the glue soaks into the drywall paper and during any eventual removal, it will rip the paper apart.

This is exactly what happened to me but only in certain areas was it bad enough to tear off the paper to the bare brown layer in the drywall.

Do you think adding some drywall compound and sanding it down is the best way to go to repair that? Would something like that require more than 1 coat of the drywall mud?

sirwired 08-28-2008 11:53 AM

Repair of that problem involves coating the damaged areas with either Zinsser Gardz or Sherwin Williams PrepRite Drywall Conditioner. These products prevent further water intrusion, prevent swelling, and stiffen up the fuzzy paper so it can be sanded down. After apply the product, sand, dust, apply joint compound, sand, dust, and then prime and paint as usual.

If you don't lock down that paper, the new joint compound will cause it to absorb the water and swell.

Previous advice is right-on.

Use the recommended product, first before you attempt to coat anything. It will keep the torn paper areas from bubbling.
