    Easy to apply

    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.

    Best sealer on the Market , Easy Application

    Fast shipping. Easy application process. After application water beads up. You can really see the difference. I used to seal may patio, garage floor and driveway. Don’t hesitate to purchase. A+++++
