| Texture | Aggregate | Indicative size |
|---|---|---|
| Light | Polymer additive | Fine stir-in grade |
| Medium | Graded silica | 0.3–0.6 mm |
| Aggressive | Coarse silica | 0.6–1.0 mm |
| Heavy industrial | Aluminium oxide | 16–36 mesh; about 0.5–1.2 mm |
Light Slip Resistance
Fortis Non-Slip Additive is mixed into compatible epoxy or polyurethane at 2–5%, or 20–50 g/L. Stir thoroughly and periodically during application for even distribution. It suits garages, workshops, walkways, stairs and general floors.
Silica Sand for More Texture
Use clean, dry, graded silica rather than building sand. A 0.3–0.6 mm grade provides a medium profile. Coarser 0.6–1.0 mm sand creates a more aggressive finish for wet areas, ramps and industrial floors. Broadcast into the wet coating, allow it to cure, then remove loose aggregate before applying a compatible seal coat.
Aluminium Oxide for Aggressive Floors
Aluminium oxide is harder and more wear-resistant than silica. It suits ramps, loading areas and heavy traffic. A 16–36 mesh blend is about 0.5–1.2 mm; commercial blends can average 0.7 mm. Broadcast into the wet coat and lock it in with a compatible topcoat without burying the profile.
Test the Complete System
Aggregate size, broadcast rate, coating thickness and topcoat determine the result. Prepare a test area. Where a slip rating is specified, test the floor to the applicable standard. Follow safety information and control dust when handling silica or aluminium oxide.
