Base preparation

   Concrete or cement basis should be not less than 28 days «old», the temperature – not less than +5° and the strength not less than 20 MP. All construction joints, gaps, cracks and holes, which can create leakage of the mixture, must be filled in. All defects must be cured. A dempfer tape must be laid along the perimeter (and columns) of the floor.  The surface must be cleaned from any dust, mud, oil or bitumen spots, paint, etc.

   The surface must be cleaned from any dust, mud, oil or bitumen spots, paint, etc. The surface must be treated with a high adhesion floor primer IVSIL TIE-ROD. In case of capillary raise of humidity, the surface should be covered with a layer of hydro-insulation mix IVSIL VODOSTOP.

Mixing of mortar

   Pour the content of a mix pack into a mixing bucket with clean water in the proportion of 1 kg of dry mix per 0,19-0,21 L of water and thoroughly stir it with the help of a mixing drill until homogeneous mixture is received. Leave it for 5 minutes, then stir again. Ready mixture should be used within 20 minutes since it was prepared. Adding to much water to the mix may result in loosing strength characteristics of the mixture and appearance of cracks when the floor has dried.

Application

   Install screed rails in every 1,5-2 m. Pour ready mixture on the surface, spread and level it with the help of the walking trowel and screed trowel. If the area is more than 30 square metres, it is necessary to treat deformation joints. It is also necessary to do flooring as a non-stop process, avoiding technological breaks, until required level is achieved. Do not allow draughts, direct sunshine or sharp changes of temperature or humidity whilst the floor is getting dry. Air and basis temperature must be from +5° to +30°.

   You can walk over the floor in 3 hours. Ceramic tiles, parquet, laminate can be applied on top of the surface. One can start tiling not less than in 10-12 hours.

   Application of other materials should be done according to manufacturers instructions, with the necessary humidity level control (maximum humidity level 3-4%). Prior to application of carpetlin, linoleum or other thin decorative materials, it is recommended to apply finishing-off floor mix IVSIL TIE-ROD-II over the screed layer before to lay carpetlin, linoleum or other thin decorative covers. IVSIL EXPRESS-FINISH (applied after not less than 5 days) or IVSIL TIE-ROD-III (in 14 days at least).
