    Glossy Water-Based Polyurethane Sealer Mini Kit 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.

     

    Coverage:

    When properly applied, the sealer mini kit will cover approximately 50 square feet on an un-primed surface or up 60-75 square feet on a primed surface. Coverage will vary with surface conditions. Proper ventilation to the outside and following safety recommendations during  application is advised.

    Surface Preparation:

    All surfaces should be clean, dry and free of any debris prior to application. Sand down or fill with slurry all “pinhole” air pockets or voids in the countertop surface prior to application. Sand and repeat until all pinholes and voids are filled. The surface should be polished to no more than 200-grit prior to sealing. See our video, How to Make and Apply a Countertop Slurry Parts 1 and 2, for more information.

     

    Mixing Instructions:

    As a two-part system, Part A must be thoroughly mixed into Part B in order for the material to properly set up for application. Stir part A with the wooden stir stick prior to adding part B as settling can occur. Mix three Parts “A” to one Part “B” in a separate container for smaller projects. Immediately replace each lid tightly. For larger countertops, add the Part A into Part B and begin to mix with a wooden stir stick. Mix completely; fold the material over onto itself and carefully scrape the sides of the can to assure nothing is left unmixed. The contents should thicken and become whiter as you stir. Stir for 2-4 minutes until totally combined.  Once mixed, the pot life for the sealer is approximately 1 hour.

     

    Application Instructions:

    When applying in optimal temperature and humidity conditions of 75 F and 50% humidity, 550 Polyurethane pot life is approximately 1 hour before the material begins to harden. Do not apply to surfaces below 65F or above 90F or if humidity levels are above 80%. Lower temperatures will maximize pot life and higher temperatures will reduce it. The sealer itself must be above 60F before installing.

     

    Water-Based Polyurethane Sealer can be applied either with a de-fuzzed 3/8″ nap roller or with HVLP Gravity Feed Spray Gun with compressed air for finer finish. For complete application instructions, read our How to Apply Polyurethane Countertop Sealer Guide.

    Sealing an outdoor countertop? Always apply sealer late in the evening or very early in the morning when the concrete is at its coolest temperature regardless if the countertop is in direct sunlight or not.

    Soy Gel Paint and Sealer Stripper

    Water Based Polyurethane Sealer can be cleaned prior to cure with isopropyl alcohol. The sealer can only be removed from fully-cured concrete surfaces using industrial paint strippers, such as Soy Gel Paint and Sealer Stripper, or by mechanical means, such as grinding or sanding. Leftover product, brushes, paint trays, or roller covers should be responsibly discarded after use. Clean countertop surfaces with a mild dishwashing soap and water.
