Base preparation

   The blocks surface should be carefully cleared of dust, dirt, oils, and greases.

Mixing of mortar

   Dry mix is poured into a mixing bucket with clean water in the following proportion: 1 kg of dry mix for 0,21-0,23 l of water. Then it is thoroughly stirred, manually or with a mixing drill, until the mixture is homogeneous and elastic. The mixture is left for 5-10 minutes and then stirred again. Prepared mixture should be used within 2 — 2,5 hours!



   Ready adhesive for foam-concrete is applied to the prepared surface of a block or a panel and spread by a notch trowel. After blocks or panels are laid, they should be pressed towards each other by circulating movements for achieving optimum thickness of adhesive layer (2-5 mm). When working with non-grooved blocks and panels, adhesive mixture is applied on vertical and horizontal surfaces. Blocks should be laid not later than 10 minutes after application of adhesive mixture. The position of blocks can be corrected by a rubber hammer within 10-15 minutes after they are laid. Time of drying – 24 hours.

Consultation on the pplication materials



   Adhesive for assembling foam-blocks, aerated blocks and foam-concrete IVSIL BLOCK is based on cement, imported polymer additives and fractioned sand. It is suitable for laying grooved and non-grooved blocks and panels made of aerated concrete, foam-concrete, polystyrene- concrete, silicate, blocks made of porous concrete, cellular bricks, cellular concrete; it is suitable for use with other insulation blocks, for interior and exterior jobs.

   Adhesive for foam- concrete allows to lay blocks and boards with a minimum width of adhesion layer of 2mm, which prevents walls from freezing as there is no access for frost via so called «frost bridges» formed by layers of adhesive. Thin adhesive layer guarantees minimum consumption of the material, makes work with aerated concrete and foam concrete blocks easier, faster and even more economical as compared to traditional sand-cement mortar mix.

   The basic price of adhesive for foam blocks is 185 rouble/25 kg. Price of other IVSIL assembling adhesives can be found in the section «Price list».
