Green Glue Noiseproofing Sealant

Horrible, unusable product. Purchased two boxes of this sealant for a two layers of 5/8 Sheetrock job for my ceilings. If your gaps between sheets of drywall are more than 3/16” you are screed. Sealant is so liquid, that it is falling right back on you, on walls and in a floor in a minut or two. But if your gaps are like 3/8”,it is falling right back. Instantly. You need to grab your putty knife and start “sparkle” it right back into your seams. 3/16” gaps doesn’t looks good too after two day of drying.. Suffered for two complete workdays. Sheetrock gaps looks horrible. This useless sealant goes back to Amazon tomorrow. Complete waist of time, effort and money. Putting this materials in to a fridge for overnight doesn’t help at all. G-d only knows how I’m going to go over this stuff with paper tape and joint compaund.
