Can this be used for knockdown texture?

Asked by Mjolnir January 9, 2019

Answers

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 :-)

Was the color of the lid on these change?

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.

It has different uses. The type of mud used depends on what stage of the process your in, i.e. final skim coat. This mud isn't recommended for everything, use all purpose if your looking to use for everything.

I just finished sheetrocking, can i use this on the wall to get it ready for painting?

Asked by Geo August 19, 2016

Answers

Yes. Use sheetrock tape, go over it with a thin layer of compound, let it dry, then repeat. You need to go wider with each layer and sand until the wall is smooth and you can't see or feel any screws, tape, or other blemishes. It helps to use a light to shine up the wall to spot imperfections.

Yes, but only on the last coat. A hard mud such as 45 minute or 90 minute on the first coat.

Ready to use from the bucket. Good consistency for easy application. No additional thinning required unless maybe you are doing skim coat. Since 4.5 gallons is a bit much to drag around I scoop a bunch into a 3.5 quart bucket from previous jobs and just carry that light one up and down the ladder.

Best tape adhesion of any USG bucket mud I've tried. Almost as good as Quick Set or DuraBond.
Note the way the different compounds held the paper tape in the test pictured. Some peeled away clean in spots (not good) and others held so well that the tape actually delaminated meaning perfect adhesion. Light Green Ultralightweight was the best of bucket muds in my test. Quick Set Light is one of the few with perfect adhesion. USG DuraBond also has perfect adhesion in this test. Based on this, I would trust Ultralightweight for taping over most other compounds if I could not use DuraBond or Quick Set due to using automatic taping tools or some other reason. ProForm Black fails this test as does their Blue. Unfortunately, my phone is only allowing one photo. I'm not able to post the proform test picture for comparison. It will be in my proform quick set reviews.
