Beyem Comfort

Extra-white polymer-modified and multiple consistency flexible adhesive with accelerated adhesion for the universal fixing of modular coatings.

BEYEM COMFORT is an extra-white geopolymer-modified and multiple consistency flexible adhesive with accelerated adhesion for secure bonding ceramic tiles and natural stone. Formulated with geopolymer, synthetic resins, selected aggregates of exceptional whiteness, fibers, pozzolan and last generation superabsorbent polymers that provide an exceptional workability, accelerated adhesions and an effective pore structure that translates into a superior wetting capability in a greater range of thickness and consistency of the adhesive. It does not cause settlement. No vertical slip. Resistant to mechanical stress in all its types (tensile strength, flexural strength, compression and shearing).
Excellent durability (chlorides, CO2 penetration, sulfates, arid-alkali reaction and freeze-thaw cycles) thanks to its special formulation.
Indoor environment quality. Classifed as A+ class according to Décret nº. 2011-321 (France). Free of radionuclides.

Protected with Sanitized®. Mildew resistant. Indoor environment quality. Classifed as  A+ class according to Décret nº. 2011-321 (France). Free of radionuclides.

Laying of ceramic tiles of low/medium/high absorption, natural stone, vitreous mosaic, porcelain and stoneware tiles , etc … in interior walls and interior and exterior floors. Laying of ceramic tiles of medium/high absorption in exteriors walls. BEYEM Comfort is especially suitable for laying natural stone, since it significantly reduces the formation of efflorescence. Thanks to its geopolymer-based formulation, BEYEM Comfort exhibits excellent performance on underfloor heating and/or cooling compared to other conventional solutions. Applications on gypsum-based substrates without the need for prior priming.

Suitable for laying ceramic tiles and existing ceramic tile floors. Swimming pools. Industrial and commercial applications (heavy traffic…) on floors. Ideal for industrialized construction and rehabilitation where a rapid development of performance and a wide range of thicknesses of use are required. Regularization.

BEYEM COMFORT is suitable for the following substrates , among others:

  • Cement  based substrates.
  • Cement based renders /plasters and screeds. Concrete floors. Cement based waterproofing membranes.
  • Plasterboards. Gypsum-based substrates.
  • Cellular concrete.
  • Compact natural stone, underfloor  heating and existing ceramic substrates (overcoating)
  • Use over other materials (wood, anhydrite, etc …) with previous BEYEM PRO primer.

Super absorbent polymer on modified sepiolite
Provides an effective pore structure with “sponge” effect: the water is concentrated in the cavities of the adhesive, making a reserve and releasing it as needed.
Allows the use of the adhesive in a wide range of consistencies and thickness thanks to the intelligent management of the mixing water.
Allows internal curing of the material
Reduces the formation of skin by drying on the surface due to the homogeneous distribution of water. Result: Triple open time

Certificados Beyem Comfort

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.

Mix manually of mechanically BEYEM COMFORT  with 6,5-8,0 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 1-2 m2 or no more than can be tiled within 30-40 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.

  • Do not apply on plastic, metal or wood.
  • Do not apply below 5ºC or above 30ºC.
  • Do not apply when there is risk of frost, rain, strong wind or direct sunlight.
  • Leave joints between tiles with a minimum width of 2 mm in interior situations and 5 mm in exterior works. Grout with BEYEM JUNTA UNIVERSAL or BEYEM ADVANCE.
  • On floors with a surface area greater than 30 m2 , it is recommended to leave separation or sealing joints filled with a deformable material.
  • On interior floorings larger than 15 m2, it is advisable to keep a free perimeter expansion joint between the floor and the wall or pillar, hidden by a skirting board (of approximately 5 mm).
  • On facades and external cladding, the material should always be fixed with anchors or mechanical fixing, when some of the following conditions apply format above 900 cm2, one side of the largest piece is larger than 60 cm, weight above 40 kg/m2 or height of tiling up than 3 meters.
  • Existing ceramic tile/natural stone: requires preliminary treatment. Do not use on very low absorption rehabilitation substrates.
  • Underfloor heating/warming: the heating must be off, and should be turned on gradually at least 5 days after tiling and grouting.
  • The temperature, ventilation, and absorption of the substrate and covering materials, may vary the adhesive workability and setting times.
