Application Surfaces

Gypsum-lime mortar for machine and manual application on internal walls of brick, blocks, siporex blocks and concrete. The product is not applicable for sanitary blocks and for surfaces on which ceramics will be installed.

Application

The surface to which mortar is applied must be solid, clean and dry, with no loose parts, free of oil stains and similar. The closure of holes, joints, electrical openings should be completed before applying the mortar. In case of applying the mortar on concrete or other smooth surfaces, BK-BetonKontakt should be applied to the substrate in order to improve the adhesion of the mortar. In case of highly absorbent, porous substrates (siporex blocks), a BK-Nivelator should be applied to the substrate to prevent uneven drying and cracking of the mortar. The preparation of the mortar is done by intensive mixing of the powder with about 30% of water. Apply mortar by machine in caterpillar pattern with a minimum thickness of 10 mm and a maximum of 25 mm. After that, spread the mortar with an H-shape plastering derby, trim, felt and level. For larger mortar thicknesses it is necessary to apply the mortar continuously according to the fresh-to-fresh principle, up to the required thickness (max. 40 mm. The mortar must cure evenly. Direct heating of mortar is not recommended. See product datasheet for more detailed instructions.

Consumption

Approximate cost: 10-11 kg / m²

Drying time

The second layer is applied after the first one is completely dry, which after 6-8 hours under normal conditions (T = + 23-25 ​​° C, relative humidity of the air = 50-60%).

Dilution

The mixture is prepared by slowly adding the powdered product and approx. 36% water (approximately 9 l water for 25 kg putty or about 1.8 l water for 5 kg putty), stirring continuously with an electric stirrer until the mixture is moistened evenly and homogenized. Then leave for 10 minutes and re-mix and, if necessary, add some water to obtain the proper consistency.
