For bonding ceramic tiles (absorbent and weakly absorbent tiles 60x60 ), gres tiles, mosaics, marble, granite, natural and artificial stone on wall, floor and facade surfaces, exclusively on solid substrates (concrete, cement and lime mortars), for exterior and internal use. Excellent adhesion, high strength, flexibility and moisture resistance. Suitable for use in bathrooms, kitchens, balconies and terraces and underfloor heating systems.
PREPARATION AND APPLICATION
The substrate on which the adhesive is applied must be solid, clean, wearable, freeze-dried, free from staining, free of oil or paint residue. Before bonding the tiles, it is advisable to coat the BK-Ultra Prime substrate in order to improve the adhesion of the adhesive. For optimal results when gluing tiles on low-absorbent surfaces use in combination with a BK-Bond primer. Preparation is carried out by adding the 25 kg of powder in about 6,5 l water with vigorous stirring until complete homogenization. Allow the mass to stand for about 10 minutes, then stir again to obtain a suitable density adhesive. Apply the adhesive with a serrated trowel with a suitable tooth size so that a minimum of 65% of the surface of the tile is covered with adhesive (for internal use) and a minimum of 90% (for external use). The size of the teeth depends of tile dimensions (4-6 mm optimal for tiles size 10-25 cm). . Insert the tiles into the adhesive layer on the substrate, and if the surface is uneven, apply the tile to the tile, thus leveling. High absorbent, porous tiles should be moistened before installation. Excess remove the adhesive with a damp sponge and mechanically seal the hardened parts. Remove excess adhesive in joints mechanically. See product datasheet for more detailed instructions.
