Features & Benefits
- Ready-to-Use Product Features
- General Characteristics
- POLYSPORT PU 951 has excellent mechanical properties, like high impact.
- It is applied on prefabricated subfloors of sports flooring such as ISOPOL 854, sh°Ck-pad in rolls, or wet-pour rubber cushion mix of SBR rubber granules and PU BINDER 1118 after they are sealed with elastic pore sealer POLYSPORT STUCCO 950. Combines finally with polyurethane finish paint POLYSPORT 952 for the creation of a multilayer polyurethane floor, especially designed for sport halls such as tennis, basketball, handball, volleyball and multipurpose halls.
- Applies easily with trowel, providing excellent self-leveling properties.
- Highly flexible and elastic contributing in the athletic performance of the flooring.
- Non shrinking.

- 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 10 ο C during application and curing of the materials while relative humiditydoes not exceed 75%.
- Application of prefabricated sub-floor ISOPOL 854 using PU FLEX 140 or wet-pour rubber cushion mix of SBR rubber and PU BINDER 1118.
- Sealing of surface porosity of ISOPOL 854 using elastic pore sealer POLYSPORT STUCCO 950.
- Care should be taken that the porosity of prefabricated subfloor ISOPOL 854 using POLYSPORT STUCCO 950 is eliminated to avoid surface defects on the final surface of POLYSPORT PU 951.
- The next day, depending ambient temperature, follows application of POLYSPORT PU 951. Components A & B (hardener) packed into separate containers in fixed weight proportions are mixed together using a low revolution mixer (300-600 rpm) for 1-2 min. Stirring of the mixture should be performed thoroughly near the sides and bottom of the container in order to achieve uniform dispersion of the hardener. The resin component should be thoroughly stirred to incorporate any slight separation, whilst continuing stirring the contents of the hardener container should be added. Continue stirring until a homogeneous mix is obtained. The mixed material must be used within 20-30 minutes of mixing at 25ºC.
- The polyurethane mixture is poured on the floor and spread using V - notched trowel 5.5 mm, with parallel use of special spiked-roller in order to release any possibly entrapped air and avoid the formation of bubbles.
- The next day, depending ambient temperature follows application of finishing paint POLYSPORT 952.
- Consumption
2.0 - 2.2 kg/m² for 1 layer.
- Application Tools
V - Notched trowel 5.5 mm, spiked-roller. Tools should be cleaned with PU SOLVENT immediately after use.

Technical Details & Test Data
- Remarks
- In case the layer of PU self-leveling 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 self-leveling can be applied.
- Working time of POLYSPORT PU 951 decreases when ambient temperature rises.
- Prolonged storage of partially used containers containing POLYSPORT PU 951 must be avoided as contact with atmospheric moisture will result in skinning and clouding of the product.
- All surfaces should be thoroughly cleaned from dust and residues prior each application.
- After hardening POLYSPORT PU 951 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.
