Grès 1 powder, ideal for renovating and maintaining matt porcelain stoneware, removes grayness without altering the surface. Makes cleaning easier and restores shine. Available in 1, 5 and 25 kg. French made.
 Product Details:
 GRES 1 allows the residual cement veil to be removed without risk after installation. Thanks to its low-dose fluorinated acids, GRES 1 eliminates the grayness of tiles without the risk of enlarging the pores, in order to respect their original UPEC. GRES 1 improves the surface condition of the tile. The gloss obtained is between 8 to 12 points. On the second application, the mechanical gloss increases: between 12 to 18 points. It remains below 25 points, so the ground is non-slippery when wet. Important note: GRES 1 should not be applied to glossy polished porcelain stoneware, as there is a risk of tarnishing it. In the event of alternating matt and glossy tiles, use GRES 2 finishing powder.
