Rated 4.0 out of 5.0 by Joint Compound and more Base on my use of this product .... Used to tape joints and apply a heavy artisan plaster finish to all the walls & ceilings in my woodshop. Worked well as a joint compound and feathered out smooth. Some shrinkage during the curing so a second feather coat was used. Since the top coat was thick, I had no need to sand the tape joint/screw coats prior to application. Remove only what you plan on using in about 5 minutes and place in a mud tray. Keep a lid on the bucket so the product doesn't dry out. I found that a 5 minute window gave me the best results for feathering. The product has a longer work time but 5 min. or less gave me the optimal consistency. Purchased the 1-callon bucket as a "trial size" and have since moved to the 5-gallon size of the same material.

Rated 5.0 out of 5.0 by All-Purpose Pre-Mixed Joint Compound One of the reason I got this was the 1-Gallon Plastic Tub. The tub keeps it from drying out. The box version I always make a mess on the bag and it drys on the sides and when I open the bag it fall into the wet mud. Plus I don't need that much mud. It's the same product from Westpac but in a tub. They make great products. It dries pretty quick. It states 24hrs to dry, but it depends on how thick you apply it. There is minimal shrinkage. Goes on real smooth. August 27, 2014
Rated 5.0 out of 5.0 by Works as expected For a first-timer at wall texturing, this product was easy to use and the patch results mostly match the existing wall texture (due to user inexperience, not product quality). June 11, 2014
Rated 5.0 out of 5.0 by Good value This is easy to work with and a good value. It is harder when it dries than some other joint compounds I've used but it sands easily. August 18, 2013
