Rated 4 out of 5 by Taping Drywall to Artistic finish Finally applying my tape and final finish to my woodshop walls & ceiling. Chose this Westpac ready-mix product for ease of application after a trial run of the 1-gallon size. I have now applied over 25 gallons of this covering screw heads, taping and application of heavy artistic finsih to the walls & ceiling. My keys to success with this product is as follows: keep a lit on the can when not in use, remove only the amount from the 5-gallon bucket that I will apply in about a 5 minute time span, never put un-used product back in the bucket, use a small tape knife to remove product from the bucket (don't use that knife to apply with) and remember that it will shrink a small amount and mistakes can be sanded away! Be creative and go for a creative finish. Adheres well with minimal to no sag. October 11, 2012
Rated 4 out of 5 by You always use more than you think I used this both for patching and, watered down, to spray a knockdown texture. For the texture, I watered it down about 20% and a 5 gallon bucket seemed to cover about 120 linear feet (mostly 8 foot ceilings 5 windows) with a medium knockdown texture. When used for patching it does shrink quite a bit. If you want to make a flat wall, you'll need at least two coats and a little sanding. If you are just patching and aren't doing a large area, lightweight spackle might work better. If you are going to store it more than a day, use a trowel to flatten it out and pour a little water over the top. Then pour the water out when you go to re-use it. It will not mix with the compound and keep it from drying out. October 12, 2013
