Special primer to ensure a reliable bond between floor levelling compounds/screeds and ceramic coverings or natural stones on difficult substrates (e.g. wood, tiles, dispersions, rigid epoxy coatings). Can also be used on old subfloors with firmly adhering adhesive residues or paint coats.

Step by step

Step 1

Shake vigorously before use and then dilute CN 94 with water at a ratio of 1 part CN 94 to 3 parts of water (when used on wooden substrates and mastic asphalt screeds, in  combination with floor levelling compounds, CN 94 must be applied undiluted).

Step 2

Thinly apply CN 94 directly with a brush or paint brush, avoiding the formation of puddles.

Step 3

Depending on the site-specific drying conditions, work can be resumed after approx. 2 to 4 hours.
