There are many types of sealers available in the market, but they are generally classified into two: solvent and water-based concrete sealers. The well-known and commonly used type is the water-based concrete seller.
Two types of concrete sealer are penetrating and film-forming sealers. Penetrating sealer gives the concrete a natural and matte look. Film-forming sealers such as acrylics and polyurethanes also come in the water-based form.

They likewise make the concrete durable, but the purpose is more for the aesthetic aspect. People have come to know the benefits of having their concrete pavements or surfaces hence the interest on sealers grew.
There are several advantages of a water-based sealer. One of which is that a penetrating concrete sealer keeps the surface of any concrete, granite or other stone free from any stain or discoloration.
It even repels the surface from oil or other corrosive materials. Water that damages the concrete is also prevented from penetrating the pores of the concrete. Usually, penetrating sealer goes as deep as 1/8 of an inch from the surface.
The second advantage of this type of sealer is that it maintains the concrete's look. It is almost invisible and the original appearance of the concrete is barely altered.
Some sealers, give off a yellowish color on the surface, a water-based concrete sealer does not. Topical sealers commonly darken the color of the concrete's exterior this is contrary to a water-based sealer.
