This grout is a flexible polymer modified waterproof tile grout with a minimum compression strength of 35MPa such as Kemgrout Flexible manufactured by Construction Chemicals and shall be applied in accordance with the manufacturer’s application instructions.
Mix grout to a thick, uniform, creamy mixture by adding powder to clean water - Ratio of approx. 0.5 litres of water to 2 kg of powder. Do not over mix, or add excessive water as shrinkage cracks may result. Allow to stand 5-10 minutes then restir before use.
Grout tiles after the adhesive has had sufficient time to set – 24 hours for walls and 48 hours for floors. Dampen the tile joint with a sponge and apply the prepared grout, spreading 3m2 at a time, working well into the joints with a sponge, grouting tool or piece of rubber. Point joints with the edge of a grouting tool or piece of rubber to pack grout firmly into place. Remove surplus grout with a damp cloth or sponge. Do not allow the grout to harden on the face of the tiles.When a haze forms over the tiles, polish carefully with a dry cloth. • Allow grout to cure for 24 hours.
Mix grout with Flexible Grout Additive to increase flexibility in high movement situations i.e. timber floors and to increase resistance to staining and discoloration. Changes the colour of the grout to the next darker shade.
Colour shade variations can occur due to tile porosity variations, finishing techniques and site conditions. Do not use Kemgrout Flexible in expansion/movement joints, use Colour Seal. Due to movement inherent in timber floors, mix Kemgrout Flexible with Flexible Grout Additive. Swimming pools use Kemgrout Sanded.
Non-toxic, but contains cement which contains silica. Wear gloves and appropriate dusk mask.
