FF 830 is a quick-drying finishing underlayment designed for skim-coating, smoothing and leveling prior to the application of floor coverings.

The FF 830 is suited for new construction and renovations. The product is intended for indoor use on substrates of concrete, lightweight concrete, ceramic tiles, gypsum boards, wood and homgenous PVC. FF 830 is easy to use and yields a very smooth surface finish.

Pre-behandeling

The substrate shoul be clean and free of dust, cement skin, grease or other impurities that can prevent adhesion. Adhesion and surface resistance of the substrate should be no less than 0.5 MPa. Weak and porous substrates should always be primed with PP 600 and allowed to dry before applying FF 830. In terms of the primer forming a film, the temperature of the substrate must not fall below 10 °C. For best results, the ambient temperature in the work area should be between 10 and 25 °C. At higher or lower temperatures, the time for curing will shorten or extend. With the risk for cracks due to shrinkage or settings in the subfloor, a concrete surface should not be leveled within the first 28 days after casting. As a recommendation the RH in the concrete should have reached RH 90 % as the upper limit for applying the FF 830.

Mix the dry powder with max 1,8 liter water ( max 40 % ) per 4,5 kg bag. Mix for 3 minutes with a drilling machine and a whisk to obtain a lump free mix. Product may be refreshed by re-mixing but do not ad more water.

Toepassing

Protect FF 830 from excessive heat or draft conditions during the curing process. Protect for up to 24 hours after completed installation. FF 830 can be walked on after 30 minutes. Always make sure that the material is sufficiently dry before it will be covered by a carpet. The FF 830 may be covered by a carpet after 1–3 hours. The guiding value assumes a curing temperature of approximately 20 °C, 40 % RH and proper air flow.
