- Brand MAPEI
- Model: MP-KFM25-G
Description
High performance cementitious adhesive, with no vertical slip and extended open time for ceramic tiles and stone material. Meets the classification of class C2TE, Keraflex in compiance with European EN 12004 & ISO 13007-1 for defromable adhesives.
Applications
- Interior and exterior bonding, up to 15 mm thick, on floor of vitrified tiles of every type and size (single and double fired tiles, porcelain tiles, klinker, terracotta, etc.) On uneven substrates and renders, without having to level the flooring beforehand..
- Interior and exterior bonding of stone materials (provided that they are not sensitive to moisture)..
- Spot bonding of insulating material in interior such as expanded polystyrene, rock and glass wool, Eraclit® (wood-cement panels), sound-deadening panels, cork, etc..
Some application examples:
Bonding ceramic tiles (double fired, single fired, porcelain tiles, klinker, etc.) and stone materials (provided that they are not sensitive to moisture) on conventional substrates such as:
- cementitious screeds and underfloor heating installations.
- cementitious renders or lime and cement-based mortar.
- gypsum board as long as firmly fixed.
- Ceramic and stone material tiles on existing flooring (ceramic, marble, etc.)..
- Installation of floors subjected to heavy traffic.
- Laying ceramic in areas with poor ventilation or close to inhabited buildings, where dust emission must be reduced to the minimum possible.
- Installation and exterior bonding of tiles or strips (porcelain tiles, klinker, single-fired, terracotta) with highly profiled ribs or lugs.
- Technical Data Sheet (T.D.S).
