A residential pool deck needs more than a good-looking finish. It has to handle water, bare feet, sunscreen, heat, foot traffic, and frequent cleaning. When epoxy flooring is used around a pool, one of the most important choices is the non-slip additive mixed into or broadcast over the coating. Without these non-slip additives, epoxy coatings can become unsafe in wet conditions.
What Are Non-Slip Additives for Epoxy Flooring?
Non-slip or anti skid additives are textured materials added to epoxy coatings to improve grip. They create small raised points or a fine textured profile on the surface, helping shoes and bare feet gain traction. Epoxy by itself often cures to a smooth, glossy finish. That can look great, but smooth epoxy becomes slippery when exposed to water, especially on pool decks, patios, walkways, steps, and other wet areas.
How Non-Slip Additives Integrate With Epoxy Coatings
Non-slip additives are typically used in one of three ways:
- Mixed into the topcoat
The additive is blended directly into the epoxy, polyurethane, polyaspartic, or other compatible topcoat before application. - Broadcast onto a wet coating
The additive is sprinkled over the wet coating so it settles into the surface as the coating cures. - Broadcast and sealed
The additive is applied into a wet layer, then locked in with a clear topcoat. This method is common when durability and a more uniform finish are priorities.
The right method depends on the additive type, coating system, desired texture, and whether the surface must be comfortable for bare feet.
Polymer Grit vs. Aluminum Oxide: Which Additive Is Better for Pool Decks?
Two common categories of non-slip additives are polymer grit and aluminum oxide. Both can improve slip resistance, but they perform differently. These additives are often mixed into pool deck sealers, paints, or stains to create a safer surface for both wet and dry conditions.
For third option, silica sand is often used as a non-slip additive in pool deck coatings, but it is not as effective or durable as polymer grit and aluminum oxide.
Polymer Grit Additives:
Polymer grit is a plastic-based traction additive. It is often used in decorative and residential coatings where comfort and appearance matter. This additive comes as a fine dry powder that is mixed into liquid sealers or paints before application. The polymer grit dries into a textured surface that is not only slip-resistant but also visually appealing.
Benefits of Polymer Grit
Polymer grit is popular for pool decks because it can add traction without making the surface feel too aggressive.
Key advantages include:
- Barefoot comfort: Usually softer underfoot than harder mineral additives.
- Subtle appearance: Often blends well into clear or colored topcoats.
- Good traction for residential use: Suitable for many wet walking areas.
- Less harsh texture: A good option when homeowners want grip without a gritty industrial feel.
- Easy to use: Can often be mixed into the topcoat or lightly broadcast.
Tradeoffs of Polymer Grit
Polymer grit may not be the most durable choice for every setting.
Potential drawbacks include:
- Lower abrasion resistance than aluminum oxide
- May wear down faster in heavy-traffic areas
- May provide less aggressive traction
- Can be less suitable for commercial or high-abuse environments
For most residential pool decks, polymer grit is often a strong choice because it balances safety and comfort.
Aluminum Oxide Additives:
Aluminum oxide is a hard, durable mineral additive used to create a more aggressive slip-resistant profile. It is common in garages, industrial floors, commercial spaces, ramps, and high-traffic areas. The small sand like particles of aluminum oxide provides increased traction for wet and dry conditions. Often mixed with paint, sealers, and coatings, aluminum oxide creates a stronger surface.
Benefits of Aluminum Oxide
Aluminum oxide provides strong traction and excellent wear resistance.
Key advantages include:
- High durability: Holds up well under heavy foot traffic.
- Strong slip resistance: Creates a more aggressive surface profile.
- Excellent abrasion resistance: Useful in areas exposed to frequent wear.
- Long service life: Often outlasts softer traction additives.
- Good for demanding environments: Suitable for pool decks that see heavy use.
Tradeoffs of Aluminum Oxide
The same hardness that makes aluminum oxide durable can also make it less comfortable.
Potential drawbacks include:
- Can feel rough on bare feet
- May be too aggressive for lounging areas
- Can affect the look of decorative coatings
- May be harder to clean if applied heavily
- Can create a sharper texture than many homeowners prefer
Aluminum oxide can be a smart choice for steps, ramps, sloped areas, or high-traffic pool decks. For barefoot comfort, use the correct grit size and avoid over-application.
Polymer Grit vs. Aluminum Oxide: Side-by-Side Comparison
| Feature | Polymer Grit | Aluminum Oxide |
|---|---|---|
| Traction | Moderate to good | High to very high |
| Barefoot comfort | Better | More aggressive |
| Durability | Good for residential use | Excellent |
| Appearance | More subtle | More visible depending on use |
| Best for | Residential pool decks, patios, decorative coatings | Steps, ramps, heavy-use areas, commercial-style traction |
| Cleaning ease | Easier if lightly textured | Can trap more dirt if applied heavily |
| Surface feel | Softer, less sharp | Harder, more abrasive |
For many residential pool decks, polymer grit is the more comfortable everyday option. Aluminum oxide is better when maximum traction and long-term wear resistance are the priority.
Where to Buy Non-Skid Additives?
When it comes to purchasing non-skid additives, there are several options available. Many home improvement stores like Homedepot, Lowe’s and Menards carry a variety of non-skid additives from different brands. Online retailers have a large selection of products to choose from, making it convenient for customers to shop from home.
If you’re looking for a specific brand Rust-Oleum is most trusted one when it comes to non-skid additives. Their products can be found in most hardware stores and also online. For more specialty options, marine supply stores carry a range of non-skid additives specifically designed for boats and other watercrafts.
