Mapei Ultramastic 5

APPLICATION

• Bonding of heavy and large format ceramic tiles on walls.
• Indoor wall bonding of almost all types of ceramic wall tiles and mosaics, especially in areas where a long correction time is required.
• Bonding of thermal insulation panels and sound insulation panels, decorative ceiling elements and aerated concrete blocks ON most substrates commonly used in construction, provided they have been properly pre-treated. Ideally suited to non-metallic absorbent substrates.

Application examples

Sucking and non-sucking tiles (such as porcelain tiles) on:

• walls in bathrooms and shower rooms;
• wooden surfaces, provided they are moisture resistant;
• water-making membranes such as Mapegum WPS;
• Walls made of aerated concrete blocks;
• with name absorbent substrates, provided they have been properly pre-treated;
• cement plasters and lime-cement plasters;
• concrete walls made of precast panels or poured directly on site;
• gypsum plastering of precast panels;
• gypsum board;
• Painted walls (provided the paint is solid and the tiles are absorbent); test in advance for suitability.
• old tiles (provided one of the two surfaces is absorbent);
• large format tiles on walls;
• tiles on heated substrates.

TECHNICAL FEATURES

Ultramastic 5 is a newly developed dispersion adhesive based on special acrylic resins, graded mineral additives and admixtures. Ultramastic 5 is a ready-to-use, white paste adhesive. Thanks to its excellent thixotropic properties and workability, Ultramastic 5 can also be used for large format wall tiles. The open time of 30 minutes (at +23° C and 50% R.H.) ensures that bonding can be carried out in complete safety. Applied tiles adhere immediately thanks to the excellent thixotropic properties of this product. Ultramastic 5 binds as it evaporates water and then obtains considerable elasticity and excellent adhesive strength, which resists most vibrations and deformations of building materials. Ultramastic 5 features full cure with excellent performance properties. Therefore, before commissioning, wait until the adhesive has fully cured. The temperature resistance is excellent up to +90° C.
