Mapei Ultramastic 5

Application

• Suitable for bonding heavy and large format ceramic wall tiles.
• For indoor use, ideal for virtually all types of ceramic wall tile and mosaic, especially in areas where longer correction time is needed.
• To be used for bonding thermal and sound insulation panels, decorative ceiling elements and aerated concrete blocks on most common building substrates, if properly pretreated. Particularly suitable for non-metallic, absorbent substrates.

Examples of applications:

Bonding of absorbent and non-absorbent tiles (such as porcelain tiles) on:

• Walls in bathrooms and shower rooms
• Moisture-resistant wooden surfaces
• Waterproof membranes such as Mapegum WPS
• Aerated concrete block walls
• Pre-treated, absorbent substrates
• Cement and lime cement plasters
• Precast or on-site poured concrete walls
• Plaster and precast panels
• Plasterboard
• Painted walls (provided the paint adheres well and the tiles are absorbent; test beforehand)
• Existing tiles (provided that either surface is absorbent)
• Large format wall tiles
• Tiles on heated substrates

Technical properties

Ultramastic 5 is an advanced dispersion adhesive based on special acrylic resins, selected mineral fillers and additives. It is a ready-to-use, white paste adhesive with excellent thixotropic properties, making it also suitable for large format wall tiles. The open time is 30 minutes at +23°C and 50% relative humidity, enabling safe and precise work. Thanks to the high initial adhesion, tiles stay in place immediately. The adhesive cures by evaporation of water and then develops high elasticity and strong adhesion, resistant to vibrations and deformations of building materials. Once fully cured, Ultramastic 5 offers excellent performance. Allow adhesive to fully cure before putting tiled surfaces into use. Temperature resistant up to +90°C.
