Customer Questions & Answers

Can you use this product outside?

Asked by: MikeD
Since this is a sheetrock joint compound, I doubt it's ability to be used outdoors.

Is this the right product for sheetrock mudding/floating? Also is this the right product for texturing walls?

I am trying to float over a poor patch job. Someone repaired a large hole in the wall and did poorly. I need to find the right product to re_float the wall and also to texture the walls after patch work. I will be using a hopper gun for texture. Any info would be greatly appreciated. Thanks.
Asked by: chris
I used this for texturing on my walls & ceilings in a garage. Not sure if it was the right product but it worked for my use and is holding up very well years later.

4 Gal. All-Purpose Pre-Mixed Joint Compound is rated 3.9 out of 5 by 8.

For the past month I've been using this joint compound to smooth out the dated texture on the walls and ceiling in my house (by hand). I like the fact that's it's on the thicker side since it takes fewer coats and doesn't drip when I'm working on the ceiling. Yes, it can crack if you put it on too thick but it has really only been an issue for me on a day when the relative humidity was high. I also tried the USG brand, but it was too watery for my project.

Rated 4 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 2 out of 5 by from Sheet Rock brand performs better and is less expensive Normally I buy the Sheet Rock compound but my local Home Depot only had the Westpac Compound. I thought all these compounds would be the same so I bought the Westpac product. I was wrong and I thought I should share my experience. This product does not have a smooth consistency like the Sheet Rock product. Westpac compound is stiff and resists smooth application without considerable working of the product. This property adds significant time to application process and extra physical effort. Drying time is longer too. While the bucket looks larger than the Sheet Rock product, when I purchase the Sheet Rock product, from my community hardware store, I found there is actually more in the Sheet Rock container (and it was less expensive too!). If you want to dip and spread than use the Sheet Rock, If you want to work harder unnecessarily, and spend more money too, than use this Wespac product.
