Semi-Rapid setting deformable mineral adhesive. For porcelain tiles, ceramic tiles and natural stone.

Areas of application
Intended use
Substrates: existing tiles, waterproofing products, heating systems, cement-based screeds, concrete substrates, plasterboard, fibro-cement slabs, gypsum and anhydrite, brick/blockwork, lime and cement-based plasters/renders, thermal insulation panelling systems, insulating panels, impact noise insulation sheets, timber - metal - PVC

Materials: porcelain tiles, low thickness slabs, ceramic tiles, large size, natural stone, recomposed materials, glass mosaics, thermal and acoustic insulation, terracotta - klinker

Uses: adhesive, floors and walls, for internal and external use, overlaying, terraces and balconies, swimming pools and fountains, saunas and spa, domestic, commercial, industrial, street furniture.

Preparation of the substrate
Substrates must comply with BS 5385, parts 1-5, be level, cured, undamaged, compact, rigid, dry and free from any debonding agents. It
is good practice to dampen highly absorbent concrete substrates or apply a coat of Primer A Eco. Anhydrite substrates must have a residual humidity ≤ 0,5 CM-%. Cement-based screeds must have a residual humidity ≤ 2 CM-%. Anchored substrates must comply with BS 8204 and anhydrite with underfloor heating must have a residual humidity ≤ 0,3 CM-%.

Application
To guarantee structural adhesion it is necessary to apply a layer of adhesive sufficient to cover the entire back of the coating material. Large, rectangular sizes with sides > 60 cm and low thickness sheets may require adhesive to be applied directly to the back of the material. Check samples to make sure the adhesive has been transferred to the back of the material.
Create elastic expansion joints:
≈ 10 m2 in external applications (approx. 3x3 m)
≈ 40 m² in internal applications (8x5 m) with underfloor heating
≈ 100 m² in internal applications (10x10 m) without underfloor heating
every 8 metres in long, narrow applications.
Respect all structural, fractionizing and perimeter joints present in the substrates.

Shelf life ≈ 12 months from production in the original sealed packaging, protect from humidity
