The right sealer will not only protect the countertop surface, but also enhance its color and sheen. There are many factors to consider when choosing a countertop sealer.
What should you seal concrete with?
To repel water and deicing salts, use an acrylic-resin sealer or reactive penetrating sealers. If you also want to repel oil stains, use a siliconate (a type of reactive penetrating chemical sealer). Owners of newly installed concrete are often told by their contractors to seal the concrete.
Can you use polyurethane to seal concrete countertops?
Polyurethanes sealers are nearly twice as thick as an acrylic sealer and form a high-build protective film on the concrete surface that provides excellent resistance to abrasion and chemicals. They can be used on both interior and exterior concrete to impart a transparent, non-yellowing, highly durable finish.
How do you make concrete countertops look like granite?
Leave alone the countertop to let the primer dry for at least six hours. To give the shiny look of granite, sprinkle the included minerals onto a sponge.

How do I protect my concrete table top?

Does polyurethane stick to concrete?
Though polyurethane has many advantages over epoxy, it does not bond well to concrete and its thin dry film thickness will not work well as a self-leveling coating. Another consideration is that most polyurethanes are solvent based, meaning they can have high VOC’s, and may require a respirator to apply.
What do you seal a concrete sink with?
