Features & Benefits
- Ready-to-Use Product Features
- General Characteristics
- It is applied as a final, sealing layer on top of playground floorings made of SBR rubber granules plus PU binder mixture, or EPDM plus PU binder mixture, on safety tiles and on top of polyurethane outdoor sports systems such as POLYFLEX PU-EX.
- It is UV-resistant and thus absolutely suitable for outdoor surfaces, including running tracks, for UV-protection in case of sensitive, light colors such as blue, orange, green.
- Ideal for protection of EPDM rubber flooring.
Applications & Uses
- Applications
- Compatible Substrates & Surfaces
- Preparation
Applied on dry surfaces without rising humidity issues, free of materials that might prevent bonding e.g. dust, loose particles, grease etc (in case of asphalt or concrete). The success in the application depends on the right preparation of the underlay and use of the material.
- Good, dry cleaning of the surface from dust and residues using vacuum cleaner and squeegees.
- Caution must be taken so that temperature of the support surface as well as ambient air remains above 15 ο C during application and curing of the materials while relative humidity does not exceed 75%.
- The A component should be thoroughly stirred to incorporate any slight separation, while continuing stirring, the hardener (B component) should be added. Continue stirring until a homogeneous mix is obtained.
- The application is done by airless sprayer or short-haired mohair roller in 2 crossing layers.
- Consumption
- 200-250 gr/m² on polyurethane floorings
- 400-500 gr/m² on running tracks or EPDM surfaces.
- Apply two layers at least.
- Application Tools
Short-haired mohair paint roller or airless sprayer. Tools should be cleaned with PU SOLVENT immediately after use.

Technical Details & Test Data
- Remarks
- In case the layer of PU top coat is applied after more than 24 hours of the application of the last layer of PU pore filler then the whole surface must be sanded by a special sanding machine. After that the PU top coat can be applied.
- The second layer of POLYSPORT 1052-SEMIMAT has to be applied strictly within 24 hours, depending on the temperature and humidity (European conditions) or within 3-6 hours (GCC high-temperature conditions) in order to cover the surface swiftly and protect it from unwanted weather or other adverse conditions (sand dust, accumulated dirt or foreign matter etc.). In case the 24-hour limit (Europe) or the 3-6-hour limit (GCC) is surpassed or weather or other adverse conditions interfere between layers at any time, the surface might need sanding again to restore smoothness and cleanliness before applying subsequent layers of the aliphatic top coat.
- Working time of POLYSPORT 1052-SEMIMAT decreases when ambient temperature rises. Prolonged storage of partially used containers, containing POLYSPORT 1052-SEMIMAT must be avoided, as contact with atmospheric moisture could possibly cause clouding of the product.
- After hardening POLYSPORT 1052-SEMIMAT is completely safe for health.
Safety & Health
- Caution
The application must take place in well-aired places using protective gloves. Skin or eye contact must be avoided, otherwise wash carefully with soap and water.
