Rather than look at the pros and cons of a countertop sealant as a whole, it is more important that you look at the pros and cons of different sealants. There are numerous sealing materials, each formulated to provide a different level and type of protection.
Ultimately, there is no perfect sealant for concrete. Of the products that do exist, none meets all ideal criteria. Even so, by working with a company like Concrete Countertop Solutions you will get as close to perfection as possible.
Choosing an Appropriate Countertop Sealant
For concrete, a quality countertop sealant is essential. Because concrete is porous and vulnerable, it is at risk for stains and chemical damage. With this material, liquid soaks in, causing stains to form beneath the surface. The other problem is that anything acidic, such as lemon juice or vinegar, actually dissolves cement paste while etching the surface. However, when properly sealed, staining, as well as damage caused by etching, is prevented.
Previously, only acrylic and wax sealers were used. However, because concrete has become the leading material found in homes today, sealants have advanced tremendously. Depending on the desired outcome, the contractor may use a densifier, which includes lithium silicate, sodium silicate, or potassium silicate. However, you may choose a repellent, such as silane, fluoropolymer, and siloxane, or perhaps go with an epoxy, urethane, or water/solvent-based acrylic.
By using the right countertop sealant, you will end up with a gorgeous surface that is easy to clean and maintain. A properly sealed concrete countertop will also be more resistant to heat, scratches, and stains. By working with a qualified contractor, the appropriate sealant will be used.
