Concrete countertops are one of the most versatile counter fixings that are fast outpacing granite as the countertop of choice. In order to protect the countertops from oils, water, acids and heat you need to seal them with a countertop sealer. We prefer a penetrating countertop sealer over an epoxy/urethane/polyaspartic countertop sealer since they are easier to apply, less toxic and keep a natural, scratch free finish.
Most Important Features When Purchasing a Countertop Sealer:
- Resistance to acids, oils, wine and water, non-porous
- Resistance to heat, abrasions and etching, scratch proof
- Food safe formulation, non-toxic
Most Popular Countertop Sealer Brand Reviews:
Cheng : By far the most popular countertop sealer but we found the application process to be very labor intensive. Provides adequate protection yet we found liquids started to seep through after a few months thus forcing us to apply another coat.
V-Seal : Stonelok is an epoxy system originally used to seal floors was not originally designed for use on countertops. Claim you can use their penetrating sealers on countertops but they will not provide heat, acid and oil resistance.
enCounter : Offer either an epoxy or polyaspartic system, long dry time, concrete needs to have a rough surface porosity in order to be applied
CounterForm : Slightly glossier than expected since product claimed it would leave a natural finish. Sealed out stains yet we had to apply two additional coats in order for liquids to be sealed out.
Countertop Sealer 660 : We like that it is a sealer designed for use on countertops, formulated to specifically combat acids, oils, water and heat. It is non-toxic, completely food safe and meets the three most important features listed above while being very easy to apply. Product is sold as a concentrate so you are able to control the dilution ratios; left the natural looking finish we desired.
