Concrete Coatings

Coatings are liquid or semi-liquid mixtures applied to cured concrete to make it more aesthetically pleasing, improve its durability, boost its longevity and/or reduce upkeep and repairs.

How Can You Minimize Sealer Slipperiness on Concrete?

Using grit additives has become the most common method for reducing slipperiness when sealing decorative concrete flatwork on exterior walking surfaces. The grit additives are mixed into the sealer, then the gritty sealer is applied to the concrete. However, in this situation the weather was too cold to reseal the concrete. So another method needs to be used until springtime arrives and temperatures rise.

Finding the Sweet Spot Among Acrylic Sealers and Acrylic Urethanes

Contractors have relied on acrylic sealers for decades to protect concrete flooring systems, and for good reason. In the right conditions, these sealers offer optimal durability, stain resistance and a desirable “wet look” finish. However, they have their limitations too and aren’t always the ideal option for high-traffic areas and environments with extreme hazards.

Moisture Tests in Concrete: Calcium Chloride vs. Relative Humidity

When good floor coatings go bad, moisture is often the culprit.

Even cured concrete can emit enough moisture to blister, cloud or delaminate a coating, especially when a slab with no vapor barrier sits on ground with poor drainage. The manufacturers of overlays, microcoatings, sealers and specialty coatings set moisture tolerance limits for their products.
