Dilution: either undiluted or diluted according to requirements. For the protection of floors and bare walls:

Dilute MATT slightly to make it more fluid and easier to apply, by adding 200 ml of water per litre of product. On a clean and dry surface, apply one even coat of MATT using fleece (wall brush).
Wait until completely dry (about an hour) and then apply a second coat in the opposite direction to the first (i.e. horizontal if previously applied vertically or vice-versa). The floor can be walked on after one hour. For a greater sheen, buff with a floor polishing machine or a wool cloth. If treating terracotta and highly absorbent natural stone (limestone, sandstone, old quarries, rough quartzite), we recommend a base coat of a water-proofing product such as FOB XTREME or W68.Renewal of the finish (every 2-3 months): after cleaning the surface with a diluted solution of CLEANER PRO (1:200), apply MATT by diluting 500 ml of product in 5 litres of water. The floor can be walked on once dry. Restoration of the protection: remove the wax from the surface using the PS87 PRO detergent, diluted 1:5. Rinse the surface.Once the floor is dry, apply the wax slightly diluted (200 ml of water per litre of product) using a fleece pad, cloth or other applicator. The floor can be walked on once dry.For Anti-flaking treatment: apply an even coat of undiluted MATT to the dry floor using a brush. The treated surface will be dry after approximately one hour.CLEANING OF TOOLS: clean with water after use.For ordinary maintenance: use a diluted solution of CLEANER PRO (1:200)
