Ceresit CN 94 is designed for priming surfaces indoors
and outdoors before applying self-leveling floor screed, repair mixtures,
and adhesive for ceramic and stone tiles. It can be
applied to vertical and horizontal surfaces, both
absorbent and non-absorbent. The composition is particularly
recommended for critical substrates (only inside buildings),
such as substrates with difficult-to-remove adhesive
residues, ceramic tiles, dispersion, and epoxy paint
layers. The product enhances the surface of the substrate and improves
adhesion to the substrate. CN 94 can be applied to anhydrite,
cement, and asphalt mastic substrates, industrially
produced substrate elements (e.g., gypsum fiber
floor panels), concrete, including vacuum-treated concrete,
painted and unpainted surfaces on a wooden base (particle
board, OSB board), self-leveling floor screeds, already
existing ceramic and stone tiles, cement, cement-lime, and lime plasters, gypsum, and aerated concrete
substrates.
CN 94 can also be applied to underfloor heating structures

Surfaces to be primed with CN 94 must be dry, load-bearing,
and free from substances that reduce adhesion: greases,
bitumen, dust, and others. Any stains and
layers with low strength must be removed. This also applies to existing adhesive
paints, which must be scraped off and then rinsed off with water.
Gypsum and anhydrite substrates,
OSB boards, and thick paint layers should be sanded with coarse
sandpaper, thoroughly cleaned, and vacuumed.
All smooth and non-absorbent surfaces should first be
sanded and made rough. Requirements for specific
types of substrates are indicated in the table.

Shake the contents of the package several times. For absorbent substrates, dilute the concentrate with water (mix 1 part CN 94 with 3 parts water). For non-absorbent surfaces, wooden-based surfaces, and asphalt mastic substrates, apply CN 94 undiluted. Apply thin layers of the product. Spread evenly with a brush, avoiding puddles. Depending on the type of substrate, the drying time is between 2 to 4 hours. After complete curing, the surface should be scratch-resistant. Otherwise, the priming procedure must be repeated within 24 hours. Clean tools and fresh spills with water. Hardened stains can be removed with solvent.

Work should be carried out under dry conditions, at air and substrate temperatures of +5 °C to +25 °C. Avoid drafts. CN 94 must not be disposed of in sewers and mixed with other additives.
