In particular, it must be free of traces of release agents, curing agents, grease, laitance, plaster, etc. The substrate is moistened beforehand if necessary (application on a highly absorbent substrate or one that has been exposed to the sun, in hot weather). The surface must not be damp and must be free of any film or puddle of water on the surface during application. Stir with clean water to the desired consistency using an electric mixer at low speed (about 500 rpm) until a homogeneous paste without lumps is obtained. Mixing rate: approximately 28%, i.e. 6 litres of water per 25 kg bag, and 1.2 litres of water per 5 kg bag. Ripening time: 3 min. Prepare in advance only the quantity of product that can be used, taking into account the practical duration of use, open time, ambient conditions and the speed at which the flooring is to be laid. Spread the adhesive mortar on the substrate with a trowel or smoothing machine, then adjust the thickness with a notched spatula (choice of teeth according to the size of the flooring and the flatness of the substrate; (see product instructions). In the case of double gluing, coat the back of the element to be glued with a thin layer of adhesive mortar (1 to 2 mm). Maximum thickness of adhesive: 10 mm. Within the open time limit, lay the covering on the glued substrate and press or beat it strongly to expel the air and obtain a good transfer of the adhesive mortar. Clean the flooring with a sponge as soon as it is laid. Use SikaCeram Joint Fine, Large or Flex.
