Decorating: Working with Wall Compounds

Types of Wall Compounds

"Some people use the terms "mud", "joint compound" and "joint compound" interchangeably. There is joint compound, which comes ready-mixed or powder for mixing. And there is joint compound, which usually comes in a small tub the size of a large yogurt. The joint compound (ready-mix) is softer, more liquid content, and gray when wet; joint compound is a bit crumbly (like when you fold butter and flour?) and very white. I think you can get interesting results with each.?

I have wiped two-month-old joint compound from a wall when the previous dweller did a messy job of repairing nail holes. I don't know what the curing time for that is. So, be creative and experiment with these products, but consider sealing them in some manner to prevent losing your artwork. I'm not sure about the terra-cotta though. It is porous, so sealing on the outside doesn't have an effect on the clay pot itself if it is getting wet on the inside."

Seal That Drywall!

"Drywall compound and joint compound are not permanent until they are sealed or primed. (I have 6 walls in my house to prove it.) Mud and joint compound continue to react to water-the purpose of this is to be able to put several layers on until the finish is smooth-wet sanding in between. Once the final finish is smooth enough it must cure-for at least 72hrs.

Then it must be primed with a good primer. If it is not cured and primed properly, the paint will not adhere properly and will eventually peel away from the dry wall like wallpaper (4 walls in my kitchen to prove THAT.) My DH and I were in a rush to get our kitchen done for the twins First Communion party and we did not take the recent humid weather into account. We also skipped primer 'cause we bought a good brand of paint-BIG MISTAKE.

?The paint looked great for 3 years and then I noticed a bubble in a corner-like an idiot I picked at it and a sheet of paint about 4x4 came right off the wall-down to the bare mud!!!!? Boy have? did we learn our lesson.? (When we re-did our bath room-gutted it down to the studs-a contractor quoted us $15,000-we did it for $1,500.? We made sure that stuff was dry! If you use joint compound-same rules apply-let it Cure-Seal with a primer-then paint it."
