White cement based adhesive with fast bonding properties, suitable for bonding all types of ceramic tiles 120x80, marble, granite, glass mosaic tiles, natural and artificial stone to wall, floor and facade surfaces, only to solid substrates (cement, lime and concrete-based mortars), for outdoor and indoor use. Excellent adhesion, high strength and moisture resistance. Suitable for bonding to surfaces with pre-existing tiles as well as to surfaces with underfloor heating. It can be used for paving pools and other structures filled with water within a system using the BK-HidroStop 2 waterproofing coating. It does not change the natural color of the bonded material.
PREPARATION AND APPLICATION
The substrate to which the adhesive is applied must be solid, clean, durable, non-frozen, free from efflorescence, oil residues or paint. Before bonding the tiles, it is advisable to apply the BK-Bond primer diluted according to the instructions in order to improve the adhesion of the adhesive. The preparation is performed by adding the 25 kg powder to about 6.5 l of water with vigorous stirring until complete homogenization. Allow the compound to rest for about 10 minutes, then stir again to obtain a suitable density of adhesive. Apply the adhesive using a serrated trowel with a suitable tooth size so that at least 65% of the surface of the tile is covered with adhesive (for interior use) and a minimum of 90% (for exterior use). The size of teeth depends on the size of tiles (4-6 mm optimal for tiles size 10-25 cm). Press in the tiles into the adhesive layer on the substrate, and if the surface is uneven or the tiles are of larger size, apply the adhesive also to the tile. The tiles should be laid while the adhesive is fresh (before the crust is formed). In the case of bonding of marble and other types of stone, subject to discoloration, do not immerse the lining in water at all, and it is advisable to apply a test application of adhesive. See product datasheet for more detailed instructions.
OPTIMAL WEATHER CONDITIONS
Substrate and air temperatures from +5°C to +25°C.
TIME OF APPLICATION
About 40 minutes after stirring, depending on the temperature. Fast-setting, ready for grouting with white grout after 8-10 hours of drying, grouting with other colors at the earliest after 24 hours of drying under normal conditions (T=23-25°C, 50-60% r. h. ).
Approximately 3-5 kg/m², depending on the surface and thickness of the application.
