Answer: 
Yes. I sprayed this product with a Graco 495 with a 517 tip on full bore. No problems, worked like a champ. Spray product on and backroll with a 3/4 nap. Didn't even need a brush. Spraying this product is my preferred choice for this product... pressing a 9" inch roller into concrete all day gets old real quick.

Answer: 
I wouldn't recommend using a sprayer--a good stiff masonry brush is best for the 1st coat, then roll on the second, and you'll have better results on your project and MUCH LESS wear and tear on your sprayer system. This is a thick product and might clog your sprayer.

Answer: 
Yes. Probably the best way to apply it other than spraying. Use a nice thick nap roller cover depending on how porous the walls are

Rated 4.6 out of 5 by 34 reviewers.
Rated 5.0 out of 5.0 by Performs miracles! We have been living with a wet basement (sump pump) for 6 years. When we decided to put our house up for sale we thought we should paint the basement, if even for just aesthetic purposes. I never thought our basement would actually be dry, considering the puddles we've had over the years during spring and heavy rains. Well, I painted about a month ago and the sump pump hasn't gone off since! Unbelievable! The paint went on easily. We used 2 coats on the walls that are known to seep and 1 on the rest. Our basement is about 20x25 and I was able to complete it all in one weekend with limited help from my husband. The smell bothered him but I thought it was reasonable. We used a brush for the edges and nooks and crannies and a roller in between. We painted over moist walls. The wet walls took longer to dry by about a day. I recommend it 100% and wish we had done it sooner. August 1, 2016
Rated 5.0 out of 5.0 by Good Coverage Coverage over existing paint excellent. Easy cleanup. Another quality product from Behr. October 3, 2015
Rated 5.0 out of 5.0 by Covered Well, Satisfied Used this product to repaint previously painted basement walls. I did this for aesthetic purposes rather than waterproofing as I have had no water issues. I scrubbed the walls with white vinegar and water solutions and scraped any loose paint and cement off. The paint covered well with two coats. Used a 3" brush and 9" semi-rough surface roller. I found it went on very smoothly and looked great after two coats in most spots. My son tested his paintball gun on the walls a few years ago. That was difficult to cover and took about four coats. The smell was not overpowering and everything washed up easily. Recommend.

Rated 5.0 out of 5.0 by Works better than all of the others!!! I have spent over $2,000 on water seal products for my basement so was not sure this would work. I bought the major brands for my 1,000 square foot basement and they were not much more than paint on the walls. This is more than paint it has some grit to it that will stick to the walls. I scraped the walls before applying to get a good seal. I asked the nice gentleman at the Paint Counter to put it in the paint shaker so it would mix nice. It is a great product. About the same price as the other name brands I have used but this one works. I also bought the InvisaFlow StealthFlow Gutter Downspouts ..they are the best! April 3, 2014
Rated 5.0 out of 5.0 by Waterproof Basement Walls I have had nothing but GOOD luck using Behr products. Used the waterproofer on our basement walls and floor, with amazing results. The basement is so much brighter and fresher smelling. It has lasted 6 years and no leaks. I highly recommend Behr. June 22, 2016
Rated 5.0 out of 5.0 by Wish I'd known about this before. The first time I waterproofed a basement, I used Drylock for the basement walls of a rental. It was very labor-intensive and I wore out several paintbrushes and energetic teenagers trying to work it into the crevices. A couple years later, I happened to run into a Behr rep in the paint department as I was looking for basement paint for my own home and he urged me to try the Behr product. Wow. SO much easier to apply--just roll on like slightly-thicker-than-normal paint. It was slightly more expensive, but more than paid for itself in lower labor costs. And it worked beautifully. A couple of years ago we had three years in a row of 100-year flooding. Our neighbors all had water in their basements, but ours stayed bone dry. We don't have to run the dehumidifier nearly as much now, either. I'm always looking for cheaper ways to do things, but this product is worth the extra pennies. December 22, 2014
Rated 5.0 out of 5.0 by Excellent performance and easy application! We purchased an older home with a leaky basement, and have tried a few different products to seal the walls. One waterproofing paint was so thick and sticky it was like painting with thick maple syrup. The second one didn't cover well and the smell was awful. I started to think we were going to have to hire a contractor if we were ever going to have a dry basement. After some serious frustration and quite a bit of money spent, we tried the Behr waterproofer. What a difference! The paint went on smoothly without any drag at all, even over some rough areas where the wall had been textured with sand. The coverage was great. It has been on the walls for a couple of months now and no water or moisture yet! Very pleased! [This review was collected as part of a promotion.] February 19, 2016
