Answer: 
Yes, wait for the skim coat to set up a bit then give it a brush finish to the texture you want, wait 7-10 days AFTER it is 100% dry to paint. Used this to damp proof my basement, works great.

Answer: 
No, this material cannot be used on stairs. It does not have abrasion resistance. We do not have a product that will resurface masonry stairs.

Answer: 
Coverage depends on thickness of skim coat, 1/8" and 1 bag will cover 50-70 sq ft. I've done a lot of block wall basements and always start with a 100% dry wall and then use a big wall paper brush to dampen wall slightly before skimming but I don't drown it.
If you are damp proofing a basement 1st solve the water source problem (grading, downspouts, etc.) then dry out wall with fans and dehumidifier. Read More

Answer: 
A 50 lb bag Surface Bonding Cement yields 35-40 sq ft at 1/8 inch thick. As long as the cavities on the wall are not pooling with water then you should be fine. If there is not enough moisture on the wall the material will not stick properly.

Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Works Great, Follow the Instructions! Used this to damp proof a very leaky basement, worked great BUT you must follow the directions to the letter! Buy fresh bags that are soft and pliable, hard chunks will ruin your mix. Mix in 1 bag batches in a 5 gal pail with a drywall mud mixing paddle on a high torque drill or screwgun - 1st add 3.5 qts water then half the bag and mix like crazy, then add the rest and another 2 qts water and mix until like icing on a cake or drywall mud - smooth but not soupy, a little wetter than mortar. Do NOT dump multiple bags in a mortar pan and try and mix with a hoe or shovel, you'll have a chunky unworkable mix, learned the hard way. I applied about 1/8" thick, waited 10 days after it was completely dry before painting and two years later basement is 100% dry. Used this on multiple basement projects, great solution for damp proofing but you need to solve your water source problem - grade away from house, extend downspout exits, etc. July 7, 2016
