Rated 1.0 out of 5.0 by Worst joint compound in the USG line Worst product in the USG line. I have used just about every type of joint compound over the years (hot mud, cold mud, blue lid, purple lid, green lid…etc..) And each did something well or had a purpose…expect this. I was skeptical of this compound and would never use it for taping (that is what all purpose or durabond is for :-) ) but it was the only thing in stock at the moment and I figured that for a skim coat it would not be that bad….I was horribly wrong. First off I had the problem of air bubbles like another reviewer mentioned…ok so I remixed it to get them out and if that was the worst of it I would have been ok. This mud is prone to cracking in even the thinnest application. I used it for a second coat over paper faced drywall corner bead that was dry for 2 days and it cracked (less then 1/16th thick… I measured with a micrometer..) It cracked just about everywhere I used it too (seems, inside corners as a second coat). The mud was used in a heated house at 68 degrees with about 30% humidity…..(I have a indoor gauge). The mud does not seem to stick nearly as well as even light weight joint compound and it never dries. Since it was cracking I scraped it off the walls and it has been four day and the pile of scrapings are still damp. I am so happy that I did not tape with it and that it only failed as a second coat. I grabbed a bucked of midweight and finished the job with no problems. One of my friends also used this and had the same result…had to redo the seems and the taping…In closing this product does nothing well and is only slightly lighter the lightweight joint compound ….and fails in every way possible…….way to mess this one up USG….

Rated 5.0 out of 5.0 by Fantastic Product! I've done drywall for over 30 years and this is by far my favorite mud to work with. Ultra light is great because it requires half the sanding! Anyone who has done this job for any length of time knows how important this is! June 27, 2015
Rated 5.0 out of 5.0 by Forget the pink stuff! Great product I was prepared to buy another tub of that pink stuff that turns white when dry when a contractor turned me on to this. I'm just sorry I didn't know about this years ago. As others have said, it's easy to apply, easy to work with and easy to sand, but minimal sanding is required. I've used it on both new drywall (remodel) and repairs and love it. Very economical for a 4.5 gallon pre-mix. I don't get the negative reviews. August 26, 2015
Rated 1.0 out of 5.0 by Do not use Do not buy this. Do not use this. This product is extremely light and makes it easy to move the bucket around. This is the only benefit to this. It is harder to work with then all purpose joint compound. It is impossible to get it flat or smooth. It will take you 4 times longer to apply this. Maybe even longer. It dries very slowly. VERY SLOWLY. I had to wait two weeks for some joints to dry so I could sand them. When it dries you will have an extreme amount of cracks and pits. You will need multiple applications for cracks and they still will not be gone unless you use a different compound. I went back to all purpose compound and threw away about half of this bucket after trying it out on a small room. August 7, 2013
Rated 5.0 out of 5.0 by Ultra Light compound lighter and great to work with. Love it. only mud that I use. Less sanding. June 4, 2015
Rated 1.0 out of 5.0 by Junk Because I'm always looking for ways to make finishing drywall easier, I bought a bucket of this stuff. First off when I first used it, way too many air bubbles. It was hard to work with. Secondly, I opened the bucket about 5 weeks after buying it, and the bucket was full of mold and the compound was practically water. Junk, this stuff is junk. March 16, 2013
Rated 5.0 out of 5.0 by Try it for yourself I have been finishing drywall for years, and after reading other reviews, I feel like I'm using a different product than most of the other reviewers. After a little mixing, I have never had problems with cracks or air bubbles. I love how light weight it is, I can get more done without my arm getting worn out, especially ceilings. It's a little pricier but well worth it. April 21, 2013
Rated 1.0 out of 5.0 by all this is joint compond with extra air manufactured in it. Makes harder to work and forced to apply a second coat. I purchased and used it and has too much air in it. Its similar to what Hersheys Candy did. They fill the product with air during the manufacturing to make it lighter. Thus it requires more unnecessary coats. To get the air out and cut cost just mix in some dish washing liquid. Don't recommend this product. Use orginal joint compound. December 5, 2012
