Step 1
Step 1 Surface preparation: Clean the surface so it is free of debris, dirt, dust, mortar residue, paint and oil. There is no need to dampen lightweight blocks; they can be laid dry. Mixing ㆍBull 2 in 1 (purple) 40 kg (1 bag) with 10-10.4 liters of water, or a ratio of 3 parts mortar to 1 part water by volume ㆍMix Bull 2 in 1 (purple) with water until smooth using a low-speed electric drill for at least 3 minutes, so that the mix has no lumps ㆍLet it stand for about 5-10 minutes so the chemicals can activate, then stir again before use. Application ㆍSet the lightweight block in the masonry line, use a masonry trowel to scoop and spread mortar fully over the bed and head faces of the block, and check that the mortar consistency is right ㆍIf the mortar is too runny and the notched ridges slump and do not hold their shape, add more mortar powder ㆍIf the mortar is too thick and the notched ridges break, add a little water. Use as tile adhesive Surface preparation ㆍThe surface must be clean, dry, smooth and level ㆍ The surface must be strong, smooth, not crumbling and level (plastered or leveled surface) ㆍWet areas such as bathrooms or kitchens should be waterproofed before tiling to prevent leaks. Mixing ㆍBull 2 in 1 (purple) 40 kg (1 bag) with 10-10.4 liters of water, or a ratio of 3 parts mortar to 1 part water by volume ㆍMix Bull 2 in 1 (purple) with water until smooth using a low-speed electric drill for at least 3 minutes, so that the mix has no lumps ㆍLet it stand for about 5-10 minutes so the chemicals can activate, then stir again before use. Application Spreading the cement adhesive: use a notched trowel of a size suited to the tile (according to the standard) and spread the cement adhesive in long strokes onto the surface. Installing the tiles: place the tile on the cement adhesive immediately, press it down firmly and tap lightly all over with a rubber mallet so the cement adhesive fills the grooves and bonds completely. Leave grout joints of at least 2 mm. Tiles can be adjusted into the desired alignment within 10-15 minutes. Leave for 24 hours before grouting
