Directions of Use
01
Mix 20kg bag with 5.5 litres of clean water using an electric mixer (approx. 300 RPM) until smooth and lump-free.
02
Rest the paste for 5–7 minutes to mature.
03
Spread no more than 1 sq.m at a time; apply a first thin layer with the flat side of the trowel, followed by the desired thickness (3mm–5mm) using a suitable notched trowel sized to the tile format.
