Use
High-elasticity adhesive for fixing of ceramic tiles, vitrified tiles, marble and  natural stone, on floors and walls, on absorbent and non-absorbent, deformable surfaces.

Materials:
vitrified tiles, low thickness slabs, ceramic tiles, klinker, cotto, glass and  ceramic mosaic, natural stone, marble, granite and recomposed materials  also subjected to staining or deformation due to water absorption and thermal expansion

Surfaces:

• mineral screeds
• mineral screeds made with Biocem mineral binder
• cement-based screeds
• prefabricated concrete or fresh concrete castings
• cement plasters and cement-lime mortar
• floors and walls in polyurethane resin, glazed tiles, cement-based and resin floor tiles, porcelain tiles
• wood, metals, rubber, PVC, linoleum, glass surfaces

Internal and external flooring and walls, in domestic, commercial and industrial applications, for street furniture, underfloor heating systems, work surfaces in industrial settings or in laboratories, swimming pools, Turkish baths, thermal water baths and fountains, also in areas subject to freezing. Fixing to sheet metal used for prefabricated bathrooms, on worktops and kitchens, balconies, terraces, flat roofs and domes.

Do not use in contact with polystyrene or on surfaces which are not fully cured and subjected to moisture rising.

Preparation of substrates
Substrates must be compact and consistent, free from dust, oil and grease, free from any rising damp, with no loose, flaky, or imperfectly anchored parts. The surface must be stable, without cracks and have already completed the curing period of hygrometric shrinkage. Uneven areas must be corrected with suitable smoothing and finishing products.

Preparation
Multi Bond is prepared by mixing together parts A and B from the bottom upwards, using a low-rev (≈ 400/min.) helicoidal agitator, respecting the preset ratio of 3.2 : 0.8 of the packs. Pour part B into the bucket containing part A, being careful to mix the two parts uniformly until a smooth, even coloured  mixture is obtained. The user must mix a quantity of adhesive which can be consumed within 1 hour at +23 °C / 50% R.H. Packs of Multi Bond must be stored at a temperature of ≈ +20 °C for at least 2/3 days prior to use.

Application
Multi Bond must be applied with a suitable, toothed trowel of the type and dimensions most appropriate for the format and type of tiles used. Using the smooth part of the trowel, apply a fine layer of product, pressing down onto the surface in order to ensure maximum adhesion. Press down each tile into the ribbed adhesive to allow for maximum coverage of the surface. In environments subjected to heavy traffic, in external applications and wherever high-elasticity fixing system is required, use the double-spread technique to ensure 100% application of the product to the rear of the tiles.

Cleaning
Residues of Multi Bond can be cleaned from tools and covered surfaces with water and alcohol while the adhesive is still fresh. Once cured, the adhesive can only be removed by mechanical means. 

High-performance fixing of vitrified tiles, marble, granite and ceramic tiles on deformable substrates must be carried out using two-component elastic, eco-friendly organic mineral adhesive with no vertical slip, compliant with EN 12004 – class R2 T, Green Building Rating 2, such as Multi Bond manufactured by Adstud specialities. The surface must be clean, free from any loose, flaky parts and adequately matured. A ____ mm toothed trowel must be used for an average coverage of ≈ ___ kg/m2. Create elastic fractionizing joints every ___ m2. Tiles must be fixed with joints of ___ mm width.
