Can I mix sand into your coatings for a non skid surface?
Yes you can add small amounts of materials like sand to achieve a specific finished result, but if spraying, we recommend you use our powder additives instead. Some materials will damage your gun, and often settle to the bottom of the sprayed material resulting in no benefit. If an extremely coarse product is desired, we recommend you broadcast a fine layer after the base coat has partially cured. The resulting product could also be top coated after to encapsulate the sand or other material and smooth out the final product a bit.
Our Diamondback DB-1081 polyurea product is designed to permit large concentrations of coarse aggregate such as silica (sand). This product is most commonly used for roof repairs, koi ponds, water features, and traffic surface areas. After spreading to the desired thickness, you can broadcast these aggregates until they sit on top dry and are settled into the coating throughout. This makes for a very hard final product with enough elasticity to handle expansion and contraction due to temperature variations.
Our standard Spray Lining and Coatings brand products which are 100% solids can also have significant amounts of aggregates, but are a harder product already, so the Poly Powder is more often recommended along with simple texturing techniques
You can control flexibility as standard, soft, or hard and employ simple spray techniques obtain a rough to smoother surface using our powdered products without the need to add sand or other general materials.
