Keraflex Maxi S1 Zero

Keraflex Maxi S1 Zero is an elastic, cement-based tile adhesive, in grey or white, composed of cement, fine graded sand, synthetic resins, and special additives.
It features zero vertical slip and extended open time, and can be applied in layers up to 15 mm thick. It is ideal for installing large-format and thick tiles, without settlement on floors and without slipping on walls, as well as for applications over underfloor heating systems.
It is classified as C2-TE-S1 according to EN 12004.

▪ Bonding of all types (porcelain stoneware, double-fired, single-fired, clinker, terracotta, etc.) and sizes of ceramic tiles to exterior and interior walls and floors, on uneven substrates and plaster, up to a thickness of 15 mm.
▪ Installation, both indoors and outdoors, of stone materials (provided they are dimensionally stable and not susceptible to moisture or staining).
▪ Installation, both indoors and outdoors, of mosaics of all types, including in swimming pools.

Keraflex Maxi S1 is a grey or ultra white-coloured powder made from cement, selected graded sand, a high amount of synthetic resins and special admixtures according to a formula developed in the MAPEI research laboratories. Laying of ceramic tiles (porcelain stoneware, double-fired, single-fired, clinker, terracotta, etc.), ceramic and glass mosaics. The environmental impacts of Keraflex Maxi S1 throughout its entire life cycle have been measured using the LCA (Life Cycle Assessment) methodology and certified with EPDs (Environmental Product 2 Declaration) No. EPD-IES-0000907 for the grey version and No. EPD-IES-0009631 for the white version, certified and published by The International EPD System. Keraflex Maxi S1 is a product with very low emission of volatile organic compounds (VOC), which safeguards the health and safety of installers and final users. It is certified as EC1 Plus by the German association GEV. Keraflex Maxi S1 helps earn important LEED credits. The innovative Low Dust technology which characterises this adhesive considerably reduces the amount of dust given off during mixing compared with conventional MAPEI adhesives to make floor layers work easier and safer.
When mixed with water, Keraflex Maxi S1 forms a mortar with the following characteristics:
▪ low viscosity and, therefore, good workability;
▪ high thixotropy; Keraflex Maxi S1 may be applied on vertical surfaces without slumping and without allowing tiles to slip, even large, heavy tiles;
▪ excellent capacity to absorb deformation in the substrate and in the tiles;
▪ good capacity to absorb deformations in the substrate and tiles. S1 class adhesive: transversal deformability > 2.5 mm measured according to the test method described in EN 12004;
