4 Options For Sealing Concrete

Whether you are trying to prolong the life of a driveway or patio, or simply wanting to upgrade the look of an interior concrete floor, concrete sealing is the service needed. Sealers can protect concrete against weathering, stains, and damage while imparting beauty to the surface. There are several sealant options to choose between. 

1. Acrylic Film Sealers

The least expensive option when it comes to sealers is acrylic film types. The sealer is simply painted over a clean concrete surface, where it creates a thin barrier against damages. You can find acrylic sealers in a variety of gloss levels to fit your design needs. The main drawback is that they do need to be re-applied every couple of years, particularly in exposed exterior areas or on high-traffic interior floors. Opt for acrylic film when you need a low-cost option that will cure completely within a few hours. 

2. Penetrating Sealers

A penetrating sealer actually soaks into the concrete and fills in the natural pores in the material. This creates a strong bond that prevents moisture from seeping in and causing trouble. A standard penetrating sealer doesn't change the surface appearance of the concrete at all, making it a good choice if you don't want any gloss or sheen. It's also durable enough to last for many years, making it a standard option for exterior applications. 

3. Polyurethane Sealers

Much like acrylic films, polyurethane sealers are a surface-only treatment. Modern mixtures for concrete sealing purposes do not yellow or discolor over time. Further, polyurethane tends to be more durable and longer lasting than similar acrylic products due to providing a thicker coating, which is reflected in a slightly higher cost. You can find these sealers in a range of gloss levels, from nearly matte to super shiny, which makes polyurethane suitable for both indoor and outdoor use.

4. Bonding Sealers

A bonding sealer is similar to a penetrating sealer, except that a chemical bond is actually initiated between the sealer and the silicates already present naturally in concrete. The bond fills the pores in the concrete, thus providing a permanent sealing solution that typically never needs to be reapplied. It is most often used on exterior paving, as it doesn't provide any sheen or visible improvements to the concrete. It also takes several days to complete the chemical bonding process, so it's not a good choice if you are in a hurry.
