| Paint Additive Fine Grit 300595 | MasonryDefender Store | Non-slip texture for acrylic sealers and paints | Clear grit texture preserves surface color; chemical resistant |
| Epoxy Colored Sand Floor Paint | Unnamed/various | High-gloss, self-leveling epoxy coating with wear resistance | Marble-like gray finish; fast application |
| Random Orbital Sander, 3.0 A | Unknown | Surface prep before epoxy coating; smooths substrate | Multiple speeds; includes sanding papers |
| Pure Silica Sand, Medium (70 mesh) | Supply Co. | General use silica sand for foundry and related applications | Kiln-dried; suitable for epoxy prep as a filler or aggregate |
Dry Silica Sand Filler 4 lb Bag
- Clean, dry white silica sand designed for repair systems and concrete floor restoration.
- Blends smoothly with floor crack repair products like A-Tech 1300 for better mix control and reinforcement.
- Thickens materials to a heavy body texture, reducing sagging and enabling precise shaping in cracks and voids.
Paint Additive Fine Grit 300595 – Non Slip
- Non-slip surface when mixed with acrylic, epoxy, or oil-based paints and sealers.
- Clear grit texture preserves the original color of surfaces while adding grip.
- Chemical-resistant formulation suitable for high-traffic areas and exposed substrates.
Epoxy Colored Sand Floor Paint
- High-gloss, self-leveling epoxy coating for interior and exterior use.
- Wear-resistant and non-slip finish with a marble-like gray appearance.
- Fast application; covers approximately 0.6 m² per kit per coat, depending on surface.
Random Orbital Sander
- 3.0 Amp, 6-speed corded palm sander with dust bag for woodworking and prep tasks.
- Compact 5-inch sanding footprint with low vibration for comfortable use.

- Clean, consistent texture ideal for mixing with repair and coating systems.
- Works as a base filler or aggregate in floor leveling and epoxy prep tasks.
Buying Guide: Silica Sand For Epoxy Flooring
Silica sand selection for epoxy flooring hinges on texture, size, and compatibility with other components. Consider the following perspectives to optimize performance and finish:
- Texture and grain size: Finer sands promote smoother pours and tighter finishes, while coarser grains add body and reduce sag in heavy coatings. For crack fillers and thickening agents, a consistent texture minimizes clumping and improves workability.
- Compatibility with epoxy systems: Check whether the sand is designed to mix with specific repair products or coatings (for example, floor crack repair products or self-leveling epoxies). Compatibility reduces phases of separation and ensures stronger adhesion.
- Application temperature and conditions: Some sands and additives perform best within particular temperature ranges and humidity levels. Follow product guidelines to prevent premature curing or surface defects.
- Non-slip performance: If surface safety is a priority, pairing silica sand with non-slip additives helps achieve grip without significantly altering color or gloss.
- Color and aesthetics: Some silicas are white and may influence the final appearance of the epoxy finish. For decorative floors, consider color-neutral or compatible hues to maintain intended look.
- Volume and handling: Smaller bags or bulk purchases affect convenience and storage. For large-area projects, plan material quantities to minimize waste and ensure uniform texture.
- Durability and chemical resistance: For high-traffic or exposed surfaces, choose sands and additives that maintain texture and grip when faced with detergents or cleaners.
- Price-to-performance balance: While mineral additives vary in cost, evaluate the impact on workability, cure time, and final appearance to determine value.
