Great product!

Well pleased with this product. I purchased a gallon last year to cover my 500 sq ft car port, water still beading like first day and cleans easy. So I just purchased another 6 gallons to cover my patio and driveway. I also used this to cover my outdoor fireplace recently, I’ll have to see what that does over time, but right now it beads water like crazy. Will have to report on driveway later. Thanks for a great product and from one veteran to another, thank you for serving this great country of ours!

Love the natural look

Water beads up now and only applied one coat; pavers did not change color or sheen

Excellent product.

I used Aqua-X on a pool deck that believe it or not is 2100 sq feet. It was easy to use and performed as state. When it gets wet the water beads on the surface. Time will tell how long it lasts. Hoping for 2 years. Would definitely recommend this product!

Hi Dawn, Thanks for your kind review. Love the beading that product provides! When the beading starts to subside, clean your pavers. It will bring back the water beading. Customer Care Team - Black Diamond Coatings

Easy to apply - just brush it on

I used a 4" paint brush to brush the sealer on my 4'x6' concrete front porch and also the brick steps. The product covered the surfaces easily and I simply wiped any splashes from my vinyl stair posts and railing. There are so many precautions with the use of this product that I was hesitant to use it. Simply brushing it on with a paintbrush should be mentioned in your instructions for small areas. It soaked in and did not leave any sort of overlap residue at all. Amazing product to apply and I hope for long-term protection.

Apparently a good product.

Very easy to use, fast drying on pavers , and water beads up validating it’s sealant property. Covers about 400 square feet in my use. Time will tell if it rates 5 stars. Would order it again .

Great product

This concrete sealer was much easier to apply than the last product I purchased and lived up to its coverage claims.. While a bit on the pricey side, it is well worth the price.

Thanks Richard for the great feedback! We are so glad your project went so well.


the ease of the sealer application

Used this product to seal my concrete driveway. It sprayed on very easily with a deck sprayer. Did not even have to back roll . Will use it again when the time comes. After a rain it beaded up and puddled very well. Was really impressed.
