Concrete sealer can reduce surface grip, particularly when applied to smooth concrete or when the surface is wet. However, how slippery a sealed surface becomes depends on the concrete texture, slope, type of sealer, film build and application.

Why Can Sealed Concrete Become Slippery?

Film-forming sealers create a protective layer over the concrete. On smooth or densely finished surfaces this can reduce the texture available for grip. The effect can become more noticeable when the surface is wet.

Applying excessive sealer or repeatedly resealing without considering existing film build can also produce a smoother surface. Thin, correctly applied coats are important.

Where Is Slip Resistance Most Important?

Consider slip resistance carefully on sloping driveways, paths, steps, entrances, pool surrounds and other areas exposed to water. The existing surface texture should also be considered before choosing a sealer.

Can Non-Slip Additive Be Added to Concrete Sealer?

Where additional grip is required, Fortis Non-Slip Additive can be incorporated into compatible sealers and coatings. The particles create additional surface texture to help improve slip resistance.

Use the recommended addition rate and keep the material evenly dispersed during application. Always assess the finished surface for its intended use.
