Rated 5 out of 5 by from Fantastic coverage I used Behr premium plus ultra exterior flat to paint the outside of my house. It glided on so smoothly and covered in one coat! My neighbors and myself were amazed at the results. I even had a professional painting company come over to give me estimates for some other work and they asked what company painted the house. They were astonished that I did it myself. Great compliment from a professional.

Rated 5 out of 5 by from Only Paint We Use This is a great paint. It covers well, even huge color changes. I just built a shed this summer and painted it the same colors as the house that I painted 7 years ago. The colors matched perfectly.

Rated 5 out of 5 by from From Old and worn to Farmhouse Chic!! We used the Behr Ultra exterior flat paint for the first time on a customer's small business building this week, all I can say is amazing!!! I was worried the flat sheen on exterior wouldnt cover, Wrong was I. Great coverage and the job turned out beautiful.

Rated 5 out of 5 by from Just ONE Coat! Perfect! To help make the installation of our new self contained composting toilet a more special event, we decided to repaint the entire interior and exterior of our "outhouse" at our camp in Maine. We needed a good paint that withstand the brutal winters in the woods, yet something that would make an outhouse a bit nicer place when you needed to "visit". Since we had used Behr in the past and it withstood the test of time , we used it again. I love the fact that one coat is all it took, its difficult enough to paint with the many mosquitoes that want to dine on you. Well it looks great! A painting worthy of a new toilet!

Rated 5 out of 5 by from It really covers in one coat! I was skeptical because I had purchased other paint brands claiming “one coat coverage”, and they really didn’t cover well. We used Mesa Taupe on our home’s exterior, and it covered completely, And dried so fast That even though it rained that night, there was no damage to the paint job! Just get this paint, it actually works!

Rated 4 out of 5 by from Covers well and looks good so far Have about 75% of house painted. Ultra goes on easy and covers pretty well with one coat, at least so far with the sprayer.

Rated 5 out of 5 by from Great paint Used this on my wood deck. Applied nice and East, wood coverage was great. Spread on very easy and no 2nd coat needed.

Rated 5 out of 5 by from Great color, quick dry! Decided after a few yrs in this home we would finally paint the exterior. Took our time, did 2 coats and what a difference! It’s old aluminum siding and the paint took great to it! Before and after pic! Color used was Graphic Charcoal

Rated 5 out of 5 by from Covers Well Repainted my house which is Cedar and T-111 that had been stained a dark brown. I replaced most of the T-111 with Hardie Plank and than sprayed the house with Behr Ultra in a very light color. Overall coverage was excellent and the paint covered well for the first coat though the Cedar and Hardie Plank sucked up the paint like a sponge. Did two coats and couldn't be more happy with the result. I would recommend for wood exterior applications.

Rated 5 out of 5 by from Quality is key! For the 3rd time in 18 years, we’ve used Behr Ultra Plus exterior paint to spruce up our all cedar, cape cod home. Once again we are very pleased with the results. Over the years, we have stayed with the same color and found the paint covers and adheres very well. We receive lots of compliments on the appearance of our home. On occasion, we are asked what brand of paint we use and alway praise the Behr product. This time, painting began in mid May when exterior painting was finally permitted in Michigan (corona restrictions). 7 gallons completes the project. We purchase the paint for our painting contractor, who recommended Behr. The only minor disappointment was the fact that this year, there was no Memorial Day sale to take enhance the “experience”.

Rated 5 out of 5 by from Great coverage I used this on a shed that desperately needed painting. I was very pleased wit the ease of application and the coverage.
