CERESIT® CN 94 is a special primer for bonding of floor levelling compounds. CN 94 strengthens the substrate surface and improves adhesion and can be applied on cement and mastic asphalt screeds, prefabricated screed elements, concrete, including vacuum concrete, painted and non-painted wooden substrates, ceramic and stone tiles, cement, cement-lime and lime plasters, gypsum and aerated concrete substrates.Available pack size: canisters of 5 l
The surfaces primed with CERESIT CN 94 must be dry, load-bearing, and free of adhesion-reducing substances: fats, bitumen, dust etc. Any stains and layers of poor strength need to be removed. This also applies to existing adhesive paints, which must be scraped off and washed down with water.
Shake the contents of the CERESIT CN 94 package several times. Concentrate must be diluted with water (mix 1 part of CN 94 with 3 parts of water). For non-absorbent, wood-derivative surfaces and mastic asphalt screeds, CN 94 should be used undiluted.
Apply thin layers of the CERESIT CN 94. Spread it evenly with a brush, not creating puddles. Depending on the type of substrate, drying time is from 2 to 4 hours. After full cure, the surface must be resistant to scratching. Otherwise, the priming procedure must be repeated within 24 hours.
CERESIT CN 94 is a special primer for reliable bonding of floor levelling compounds, ceramic and natural stones on critical surfaces. CN 94 is used on non-absorbent substrates, OSB boards and for tile-on-tile application thanks to the powerful adhesion and high strengthening effect. CN 94 is recommended for vertical surfaces.
CERESIT CN 94 is designed for priming substrates inside and outside buildings before laying floor levelling mortars, patching compounds, adhesive mortars for ceramic and stone tiles. CN 94 can be applied onto vertical and horizontal surfaces, both absorbent and non-absorbent ones. The formulation is particularly recommended for critical substrates (only inside the buildings) such as: screeds with adhesive residues which are difficult to remove, ceramic tiles, dispersion and epoxy paint coats.
Works should be carried out in dry conditions, at air and substrate temperature ranging from +5 °C to +25 °C. Prevent draughts. CERESIT CN 94 must not be poured to the sewer and mixed with other additives.
