BEYEM Prime is an extra-white polymer-modified and multiple consistency flexible adhesive with accelerated adhesion for the universal fixing of modular coatings (ceramic tiles, natural and reconstituded stones, etc…). Formulated with mixed binders, selected aggregates of exceptional whiteness, pozzolan (MK), modified sepiolite, fibers 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. Deformable and with no vertical slip. Highly resistant to mechanical stress in all its types (tensile strength, flexural strength, compression and shearing).
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, low thickness ceramic, reconstituted stone, large format, vitreous mosaic, porcelain and stoneware tiles, etc … in interior and exterior situations to walls and floors. Suitable for laying low absorption ceramic tiles and existing ceramic tile floors . Swimming pools. Ideal for underfloor heating/cooling or under tile warming and 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. Flexible regularization.
BEYEM Prime is suitable for the following substrates , among others:
- Cement based substrates.
- Cement based renders /plasters and screeds. Concrete floors. Cement based waterproofing membranes.
- Plasterboards.
- Cellular concrete.
- Compact natural stone, underfloor heating and existing ceramic substrates (overcoating)
- Use over other materials (wood, anhydrite, etc …) with previous BEYEM PRO primer.
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
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.
- On gypsum substrates, apply BEYEM FIJADOR primer before.
- 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.
- Grout with BEYEM JUNTA UNIVERSAL or BEYEM JUNTA EXTRAFINA.
- 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 metres.
- Existing ceramic tile/natural stone: requires preliminary treatment.
- 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.

BEYEM Prime 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.
Laying of ceramic tiles, reconstituted stone, large format, vitreous mosaic, low thickness ceramic, porcelain and stoneware tiles, marble or natural stone, etc … must be carried out with extra-white polymer-modified and multiple consistency flexible adhesive with accelerated adhesion compliant with EN 12004 – class C2TES2, such as Beyem Prime, 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.
