Sikafloor® P 922

CE marking and declaration of performance based on EN 13813:2002 Screed material and floor screeds — Screed material — Properties and requirements — Synthetic resin screed material

Under the specified storage conditions the material has a shelf life of 12 months. For maximum shelf life under these conditions, see “Best before” label.

Store in original containers, under dry conditions and a temperature between 15–25°C. Do not expose to direct sunlight.

not restricted, but no condensation of water on the surface 

The consumption of Sikafloor® P 922 is between 0,3 – 0,5 kg/m² depending on the condition and porosity of the substrate. For high porosity substrates or to increase the protection against rising damp, a second layer is recommended.

Oven dried silica sand 0,3 – 0,8 mm could be optionally broadcasted at approximately 1,0 kg/m² not in excess into the still wet primer.

The above consumption figures are intended as a guide only and may be higher on very rough or porous substrates.

All substrates (new and old) must be structurally sound, dry and free of laitance and loose particles. Clean floors of oil, grease, rubber skid marks, paint stains and other adhesion impairing contaminants. Mechanical surface profiling by grit or shot blasting, high-pressure water jetting, grinding or scabbling (including the necessary post-treatment) are the preferred floor preparation methods.

After surface preparation the tensile strength of the substrate should exceed 1.5 N/mm² (check with an approved pull-off tester at a load rate of 100 N/s).

The residual moisture content of the substrate must not exceed 4% (check with e.g. CM device). The surface of the substrate can be damp but visible dry before the application. Do not apply the product when there is standing water on the surface. A dampproof course must have been properly installed and be intact.

Sikafloor® P 922 is supplied in working packs which are pre-packaged in the exact ratio. Before mixing, precondition both A and B components to a temperature of approximately 15 to 25°C. Pour the entire contents of part B into the container of part A. DO NOT MIX BY HAND. Mix with a double paddle mixer at high speed (ca. 600 rpm) for 90 seconds. Use always the same mixing time and mixing speed. Keep the mixer blades submerged in the coating to avoid introducing air bubbles. DO NOT WORK OUT OF THE ORIGINAL CONTAINER. 

After mixing pour the whole content of the bucket immediately on the surface. Sikafloor® P 922 should be applied when the ambient temperature is constant or falling as this will decrease the risk of bubble formation due to expansion of air that is enclosed in the concrete. Sikafloor® P 922 is applied to the prepared substrate by spreading with a squeegee and finishing with a roller.

The curing time of the material is influenced by the ambient, material and substrate temperatures. At low temperatures, the chemical reactions are slowed down; this lengthens the pot life, open time and curing times. High temperatures speed up the chemical reactions thus the time frames mentioned above are shortened accordingly. To fully cure, the material, substrate and application temperature should not fall below the minimum. After application, the material should be protected from direct contact with water for approx. 24h (at 20°C). The temperature of the substrate must be at least 3K above the dew point both during the application and for at least 24 hours after the application (at 15°C).

Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically.
