Easy application and really nice finish. Covered a lot more than I expected
This product is very durable, low odor and vocs. When apllied very thin (5 mils) with a 3/8 nap roller. Two coats will give you a glossy, scratch resistant and low maintenance finish. Leaves my customers satisfied every time.
“I acid stained and sealed a 1000 sq. ft. mechanical parts showroom floor with lots of exposed aggregate. First I ground the concrete, cleaned and sprayed the Coffee Brown Acid Stain 1:1 and sprayed a second more diluted coat. Cleaned, sealed with two coats of DCI Water Based Sealer as a primer and later sprayed a top coat of 550 Water Based Polyurethane using a HPLV sprayer. Pictures don’t do it justice. Thank you.”
This is a very good product.
When applied properly, I am sure this product will look good and be durable. However, I had trouble with the application, even using the recommended squeegee. I would worry more about putting this product on too thick, rather than too thin. If I were to use this product again, I would try applying it with a HPLV sprayer.

    Product Details

    Water-Based Polyurethane Sealer is a low VOC, aliphatic urethane coating that offers excellent impact and abrasion resistance and will provide a durable, long lasting finish for your concrete countertop.


    For best results, first apply a single thin coat of Satin Acrylic Concrete Sealer for smooth surfaces or two thin coats for more porous surfaces. Allow the primer to cure 12 hours between primer coats and a minimum of 24 hours before proceeding. We recommend you lightly scuff the primer with 400 grit paper and clean debris away prior to applying polyurethane. Priming reduces the risk of air bubbles, promotes good sealer adherence and slightly extends the Polyurethane Sealer coverage rate.



    When properly applied, 24 oz. will cover approximately 50 square feet on an un-primed surface or up 60-75 square feet on a primed surface. 1 Gallon will cover approximately 250 square feet.

    Coverage will vary with surface conditions. Proper ventilation to the outside and following safety recommendations during  application is advised.

    I have a concrete basement floor that is 40 years old and has a lot of patches and cracks. I recently ground the surface with a big machine grinder to remove mastic from old tiles. I am planning on staining it with copper sulfide and stenciling a pattern with floor paint on top. I am confused as to which sealer to apply. I was interested in polyurethane because it doesn’t require maintenance (wax) and seems to be more durable. I do live in the rainforest and my house is built into the side of a hill, so the outside of my slab is consistently exposed to moisture. Will exposure to moisture after application cause polyurethane to cloud up on surface? Also, on your website’s description of polyurethane sealer, it just says it’s great for countertops. Do you not recommend it for floors?

    The waterbased polyurethane sealer should allow a slight moisture transference. You can use the polyurethane sealer as it is more durable but in highly moisture environments (put a mat or piece of plastic down and move it after 15 min and see if the area underneath is damp) you may want to go ahead and move over to the water based acrylic. Its not that bad you apply two thin coats and then once you see the “color” fade from your staining job then just simply apply a single new coat and you restart your clock in a basement or garage environment we wouldn’t recommend a wax anyway because there is too much moisture it would negatively affect the wax.

    Indoors you can expect 5 years or more from the Acrylic before you have to recoat.

    If you go with the polyurethane you can expect about 10 years out of it (if there is not significant moisture issues) and once it starts to fail it will all fail and you have to completely strip it and reapply.
