We would not recommend the use of the Phenopatch Wallboard Joint Compound for your described application however, our DAP Plastic Wood Solvent Professional Wood Filler can be used for minor cosmetic repairs on natural wood flooring, stair treads, risers, stingers and related trim. Areas that may be subject to abrasion or wear should be protected with a surface coating, such as a high-quality polyurethane, that is "traffic rated" for flooring applications. As with any hard setting wood repair filler, it should not be applied to joints, seams or other areas prone to movement.

A:  It depends honestly. If the wall is supported by studs behind it, yes. If you have two boards without studs or span a long distance then no mud will help that. If the latter, try the flexible compound.

A:  Put saran wrap over it and press to seal before closing lid. I have had 3 mos no issues.

A:  I don't know. What I do know is if you use this product, it will not stick to anything but the floor. It's too thin and falls off the wall or ceiling.

A:  You know what, I just bought a quart of this because I had a tub of the USG brand leftover from a couple years ago and it got black mold in it. It was strange, actually; I used the 2 year old USG compound just a couple weeks ago on my walls, and it had absolutely no black no mold in it. But then I opened up yesterday, it was full of black mold forming in the bottom. I may or may not have left it open a crack, I don't think I did though, I usually close the containers of anything when I'm done. I've worked with the stuff many times and never seen that happen. I just bought this and used half the container tonight, so far so good but too soon to tell if it is resistant to mold. This compound, it does look, feel, and even smell different than the USG stuff, so maybe it is or isn't as mold resistant (in fact, I like the odor, it's not as strong as USG which is a plus). You think they WOULD put something in these compounds, a small amount of a chemical to ward off mold. But I don't know. What I did read; if you want to preserve joint compound, make sure it's sealed good, and store it somewhere where the temperatures fluctuate. I also read to seal it with a bag/wrapper to prevent oxygen from getting in the container. Some say to store your compound with a hint of chlorine or bleach to ward of mold (although I never tried or endorse that idea). And common sense; regardless of the brand, if you see any mold in your joint compound, toss it! You definitely don't want molding building materials being permanently added to your home, especially to drywall where it can grow and expand. Both compound and walls have organic materials that mold loves.
