For bonding ceramic tiles max. dimension 120×80, mosaic, marble, granite, natural and artificial stone to wall, floor and facade surfaces, exclusively on solid substrates (cement, lime and concrete-based mortars), for exterior and interior use. Excellent adhesion, high strength, flexibility and moisture resistance. Suitable for bonding low absorbent tiles (E ≤ 3%), large size tiles, when installing on surfaces with pre-existing tiles as well as to surfaces with underfloor heating. For optimal results when bonding tiles on low-absorbent surfaces, use in combination with a BK-Bond primer.
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. The preparation is performed by adding the 5kg of powder to about 1.35 l 25 kg of 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, apply the adhesive also to the tile, in order to achieve leveling. Highly absorbent, porous tiles, should be moistened before installation. Remove excess adhesive with a damp sponge and mechanically remove the hardened parts. Mechanically remove excess adhesive in joints. See product datasheet for more detailed instructions.
