A:  Found it at the bottom in black ink below the fine print. 092120

A:  I believe that is the manufacture date. Joint compound typically has a shelf life of 9 months.

A:  Thank you for your inquiry. The first six digits represent the production date. In this case the joint compound was produced on 07/14/2020. Ready mixed joint compounds have a shelf life of 9 months under good storage conditions. Store compound in protected place, because extreme heat or cold accelerates aging.

A:  Thanks for another great product.

A:  if it is like any product that after a time or the expiration date does not work the same as it is freshly made

A:  Yes

A:  Yes. used 5 containers without any issues. Cut the finish time in half.

A:  Ask a store employee!!

A:  Tanya Thank you for your inquiry. We have conducted testing at the USG Corporate Innovation Center on SHEETROCK® Brand Ready Mix and Setting Type Joint Compounds applied to Mold Tough™ gypsum panels for mold resistance. The results of the testing consistently showed that USG SHEETROCK® Brand Joint Compounds rated as well as the MOLD TOUGH™ board after four weeks of exposure to ASTM D3273 for mold resistance. We do not recommend adding anything to our joint compounds. Hope this helps.

A:  You _can_ use it on mold resistant sheetrock, but this product is _NOT_ itself mold resistant. Maybe you could add a mold inhibotor when you blend the product to remove air bubbles before using it.

A:  It light weight, thin application of dry wall is better and holds up longer, also it is easier and faster than trying to make a smooth finish with compound.

A:  You can put it on a painted wall But expect to have to put more than one or two coats because the first coat will bubble up do the fact that the painted surface in no longer porous as in a flat or naked wall

A:  Yes

A:  I don't think I would use this for a knockdown texture. My understanding is that one of the ways the manufacturer is able to make it ultra lightweight is that they reduce the amount of "glue" in the product. This does result in a compound that has slightly less adheasive properties. I would use it if I was doing a light ceiling texture, I just would not be comfortable using it with a knockdown. As far as using it on a painted wall, as you may know, paint acts as a sealer on the drywall and can cause the mud to Bubble. So I would either sand and primer the wall or put a very tight skim coat of mud before doing the texturing. Hopefully others have a little more experience and can post a more definite answer. I would be interested to hear what other users have to say. If you use this product for knockdown let us know how it works out! Happy mudding :-)

A:  I would not use it for knock down texture,its not fast drying. They have knock down texture in box in paint department which works excellent. You just mix it with water and apply. I used hundred times and it's a great product.

A:  There are several products this is another product and they all use to come in 1 gallon or 5 gallon buckets. This particular one is 4.5 gallons. Try it, I like it better than the older one I believe you are referring to. It dries with very little shrinkage. Much easier to sand also.

A:  No

A:  Thank you for your inquiry. The Ultralightweight Joint Compound has always had a light green lid.

A:  No

A:  I'm not sure how to answer your question. This has been the only color of lid I have seen on this product in our area. My understanding is that it's a newer product and for some manufacturers is replacing what they used to call topping. Although, when it comes to the color of the mud, it doesn't seem to dry as white at some of the topping I have used in the past. I hope that is helpful.
