Natural resin adhesive is suitable for bonding the following floor coverings: cork floor coverings with an uncoated reverse side, linoleum on a jute backing, cork linoleum, wool felt, cellulose fibre boards, softwood fibre boards, textile floor coverings with a textile or latex-coated backing, with a latex foam backing and a secondary backing, needle-punched felt and natural rubber floor coverings. PVC-coated and veneered cork panels, as well as cork parquet with a density of less than 480 kg/m³, must not be installed using this adhesive.

Substrate and preparation
The substrate must comply with DIN 18365, i.e. it must be level, dry and free from dust, dirt, grease and cracks. Apply a primer coat of diluted adhesive to highly absorbent and sandy subfloors. Mastic asphalt and anhydrite screeds must be levelled. Subfloors for cork parquet and linoleum must always be levelled. The cork panels themselves must be left to acclimatise in their sealed packaging for at least 24 hours in the room where they are to be laid (room temperature at least 18 °C, relative humidity max. 65 per cent). Old floor coverings are not suitable as a substrate.
Processing
The natural resin adhesive is applied evenly to the substrate using a notched trowel B2/B3 as supplied. The covering is laid immediately into the adhesive bed and pressed down evenly. Any adhesive stains must be removed immediately with water. Cork parquet and linoleum must be rolled again after 30–60 minutes using a multi-section floor roller. Any sagging areas in the linoleum must be weighted down.
Consumption
Floors that have been levelled with 350–400 g/m² using a B2 trowel. Floors that have not been levelled and are highly absorbent, as well as more textured backing surfaces, should be levelled with 400–450 g/m² using a B3 trowel.
