BEYEM NEOCAL ADHESIVO is a hydraulic lime based adhesive, formulated with metakaolin, natural hydraulic lime (NHL), selected washed aggregates, natural cellulose fiber, mineral thickeners (sepiolite) and resins to improve workability, water retentivity, open time and adhesion. No vertical slip. Allows adjustment of tiles. Especially indicated for the natural laying of tiles. Natural composition. Free of Portland cement. Indoor environment quality. Classifed as A+ class according to Décret nº. 2011-321 (France). Free of radionuclides.
Laying of small and medium ceramic tiles of medium and high absorption (Group III) in interior walls and floors. Laying of ceramic tiles of high absorption in exterior floors. Laying of natural stone with adequate absorption. Especially suitable for laying hydraulic tiles, clay tiles, majolica, etc. Suitable for underfloor heating or under tile warming.
BEYEM NEOCAL ADHESIVO is suitable for:
- Cement based substrates and lime based substrates.
- Cement and/or lime renders, plasters and screeds.
- Traditional renders and screed floors.
- Natural hydraulic lime (NHL) substrates.
Substrates must be clean, compact and free of substances that reduce adhesion such as dust, oil, grease and with no loose material. Uneven areas must be corrected with suitable smoothing and finishing products. Substrates must be free from any rising damp and have already completed the curing period of hygrometric shrinkage. Dampen substrates with water to cool down if they should be too warm, in case of wind or over absorbent substrates and wait until the thin layer of water disappears. Do not use on gypsum based plasters or paint.
Mix manually of mechanically BEYEM NEOCAL ADHESIVO with 7,75-8,75 l per bag of clean water until a homogeneous, creamy and lump-free paste is obtained. Let the mix stand for 5 minutes before application.
Small tiles must be fixed using a notched trowel of 6×6 mm. For tiles sizes greater than 400 cm2, a notched trowel 8×8 mm must be used. Spread the mixed product onto the substrate to a maximum surface area of 1 m2 or no more than can be tiled within 30 minutes in normal conditions. Unfavorable environmental conditions (strong sunlight, drying wind, high temperature as well as a highly absorbent substrate), could drastically reduce this time to a few minutes. Bed the tiles firmly into the adhesive with a slight sliding and/or twisting action, to ensure a good contact and complete coverage.
It is good practice to lift an occasional tile after fixing, to verify that the required contact is being achieved. Back of the tile must be completely wet.
BEYEM NEOCAL ADHESIVO is packed 25 kg plastic lined paper bags.
Storage: when stored unopened in a cool dry place, shelf life is 12 months from date of manufacture.
Tools can be cleaned easily with water before the product hardens. Hardened product can be remove only mechanically.
Laying of ceramic tiles, clay tiles, hydraulic tiles, majolica, etc. must be carried out with natural hydraulic lime (NHL) based adhesive, free of Portland cement, such as Beyem Neocal Adhesivo manufactured by Rodacal Beyem company. The substrate must be compact, free from any flaky, loose parts and must be clean and cured, having already completed the shrinkage stage. Existing joints must be respected and elastic fractionizing and perimeter joints must be created. Ceramic tiles must be laid with joint-gap spacers with a width of ___ mm.
