Concrete with sealers and densifiers prevent your floor from flaking off little bits of concrete dust over time. If you have concrete floors without a sealer or densifier, it’s always a good idea to have one or the other to make your concrete floor easier to deal with and prevent dusting — especially if it is an indoor floor!

Many people do not know the difference between sealed and densified floors… and the difference is huge! Both will stop dust, but the similarities stop there. Concrete densifiers are a great choice for garage, commercial, and industrial floors because they add abrasion and stain resistance. They can also be used in a grind and polish application. Using a densifier as a sealer is a great low-cost system that not only seals the surface but also hardens the top 1/16 of an inch of your concrete surface. It involves the application of a liquid silicate hardener to the concrete surface, which then has a chemical reaction with the floor. This densification reaction fills in the natural pores and voids in the concrete, and crystalline growth occurs internally. That means that the floor is both hardened and sealed at a deeper level than a sealant can reach.

The term sealer is often used to describe any clear coating that is applied over a concrete or masonry surface. Here, we are explaining acrylic sealers used for coating and protecting concrete floors or exterior slabs. Acrylic sealers get applied to a slab after it has cured for 30 days. There are many water-based clear acrylic sealers with different solids contents that range from 7% to 60% solids. The lower the solids percentage, the less protection you get. We like to use xylene-based acrylic sealers whenever possible with 40% or higher solids content. A xylene/solvent-based sealer penetrates deeper into the concrete and re-wets itself on later applications ensuring a good bond even years later. A high solids acrylic sealer protects the floor from oil and water fairly well. Acrylic sealer is often used and works well as a finish coat over stained concrete.
