Concrete countertops are fast becoming a popular alternative to such other materials as laminate and granite for use in kitchens, workshops, and bathrooms. Granite typically is the high-cost material that offers such benefits as heat resistance and abrasion resistance, allowing you to place hot pots and pans, as well as cutting directly on the counter. Concrete countertops offer similar benefits to granite, all while being less expensive.
Also, concrete can be sealed to prevent such problems as radon exposure, which has recently become a problem with granite. For this reason and many more, concrete countertops are becoming a popular choice for kitchens in homes and restaurants. However, concrete that is untreated with a concrete sealer can be at risk for many of the same problems that plague laminates and granites.
Fortunately, there is an easy fix for this: simply apply Countertop Sealer 660 to your concrete countertops if you are looking for a low sheen finish. Countertop Sealer 660 is an acrylic, water-based, non-toxic concrete sealer ideal for concrete countertops, integral sinks, fire places and furniture. Since Countertop Sealer 660 is water based it is food-safe and VOC free. This mix protects concrete from within while also creating a very thin, hard shell that acts as a barrier against chipping and etching from harsh acids and the wear and tear of everyday use.
If you are looking for more of a natural finish, the best product to use is the Countertop Sealer 770. It will not change the look, finish or feel of the concrete countertops whatsoever; however, it will protect them against the pentration of water and fluids preventing staining.
If you are looking for a high gloss finish and the most durable product possible that will resist chemicals and abrasions the best choice is the Polyaspartic 745. The Polyaspartic 745 is essentially a fast drying epoxy that is a coating which sits on the surface of the concrete countertop. It will leave a glossy finish but will completely keep out every stain possible and will never scratch, peel, flake or delaminate. Since the Polyasaprtic 745 can also be used on warehoues floors it is designed to repel forklift and heavy traffic. Before applying the Polyaspartic 745 it is best to sand down the countertop with a palm sander and 220 grit paper to rough up the concrete and prepare the countertop for the sealer.
