The Fine-Grade Anti-Skid Additive from Fasco Epoxies creates a subtle, uniform non-slip texture without sharp grit, ideal for traction without an aggressive feel underfoot. It blends easily into gelcoat, epoxy, polyurethane, and marine paints for consistent texture and controlled slip resistance. This option is suitable for marine decks, steps, ramps, and other high-traffic areas where a refined finish is preferred.

Non-Skid Paint Additive – Coarse For Gelcoat (Quart)

The Coarse Anti-slip Particle option delivers aggressive traction for wet, slippery, or high-traffic surfaces where slip resistance is critical. It is ideal for heavy-use areas like boat decks, docks, steps, ramps, ladders, trailers, and industrial floors, and it remains compatible with most coatings, including gelcoat, epoxy, polyurethane, and marine paints for durable performance.

Griptex Non-Skid Additive For Gelcoat (Awlgrip, Quart)

Awlgrip Griptex Non-Skid Additive

Designed to mix with acrylic, epoxy, or oil-based paints and sealers, MasonryDefender Fine Grit creates a textured, slip-resistant finish for patios, walkways, and floors. The texture is fine and clear, meaning it does not significantly alter color, which is advantageous for maintaining the original look of the surface while improving grip. It also offers chemical resistance for durable, high-traffic areas.

Rust-Oleum Anti-Skid Additive Aluminum Oxide Formula

Rust-Oleum Anti-Skid Additive

Rust-Oleum’s aluminum oxide-based Anti-Skid Additive adds slip resistance when mixed into epoxy, latex, or oil-based paints or stains. It is suitable for concrete, wood, metal, and fiberglass without altering the coating’s performance when used as directed. The sand-like particles disperse evenly for a uniform anti-skid texture across varied surfaces.

Buying Guide

Texture level: Choose fine textures for a subtle, foot-friendly grip and coarse textures for maximum traction in wet or high-traffic areas. Consider the surface type and whether color retention or transparency matters for your project.

Compatibility: Confirm that the additive works with gelcoat, epoxy, polyurethane, and marine paints. Some products are brand-specific, while others are universal. If you plan to recoat, ensure the additive blends well with future coatings.

Application environment: For decks and swim platforms, weather exposure and chemical resistance are important. Some additives offer enhanced chemical resistance, aiding longevity under sun, salt, and cleaners.

Ease of use: Look for pre-measured, easy-to-mest formulations (such as quart or pint sizes) that mix smoothly into coatings. Some options are ready for use with minimal stirring, while others require thorough blending to distribute particles evenly.

Color and finish: If maintaining the original appearance matters, select an additive designed to preserve color and provide a low-gloss finish. Clear or near-clear textures are valuable on already-colored surfaces.

Durability and maintenance: Consider long-term durability in marine or industrial environments, and how the texture may impact cleaning and maintenance of the surface.

Environment and safety: Review any safety guidelines, ventilation needs, and the availability of compatible clean-up methods for the chosen product.
