    We are a decorative concrete company based in Colorado. We recently started using the U-SEAL and are extremely happy with the results. We tested the product prior to applying it on one of our commercial countertop projects, and I was amazed at how well it protected the concrete. My guys found this product for me because they noticed many people using it on YouTube and finally convinced me to purchase it. I'm so happy they did. Thank you, @Fishstone, for making such an excellent product - Concrete Visions will be using this product and you have a lifelong customer here!!

    Easy and looks great

    Posted by Pax Rasmussen on Feb 2nd 2024

    We're making a fairly complicated terrazzo style concrete countertop, using crushed marble and white portland cement. I wanted a sealer that would enhance the look but also create a top coat. I considered Rock Top, but that seemed really expensive and complicated. Took a chance on this, and I love it. Easy to mix, easy to apply, and so far it's holding up GREAT. Gave my countertops an enhanced look without making them glossy/shiny like plastic.
