COVERAGE / CONSUMPTION
Preparation of the substrate
The substrate must be uniformly dry, flat, resistant to compression and tensile stress, free of dust, loose particles, paint, wax, oils, rust, gypsum residues or other materials which might interfere with bonding and must not contain cracks. Check moisture content throughout the entire thickness of the substrate with an electric or carbide hygrometer, bearing in mind that the former gives only approximate values. It is essential to make sure that no rising damp is present. The moisture content must be the one foreseen by the regulations of each country. Floating screeds over layers of insulation and screeds over bare ground must be poured over a vapour barrier to prevent rising damp.
Preparing the product
DCI PVC 788 is ready to use the product but is suggested to mix the adhesive for homogenization.
Applying the product
Apply DCI PVC 788 to the substrate using a notched trowel suitable to the format. The open time of the product is maximum 30 minutes under normal temperature and humidity conditions, which must be taken into consideration when spreading the adhesive.
Leave a short waiting time up to 10-15 minutes according to the application quantity, climatic conditions, substrate absorbency and type of covering. Make sure not to exceed open time 20-30 minutes in order to ensure proper wetting of the back of the covering. Lay in covering while the adhesive is still wet and the solvents have evaporated and the adhesive ridges have to be impressed. Take care to avoid air pockets and carefully rub the floor covering down to ensure good adhesive transfer to the backing. Avoid excessive stress on joints. After some minutes of installing the floor covering, it is always necessary to carefully roll it down again or to firmly rub it down. Errors cannot be corrected because the adhesive sets instantly.
