Beyem Dir

Thick bed standard cement based tile adhesive for interior use.

BEYEM DIR is a thick bed standard  cement based tile adhesive, formulated with cement, selected aggregates and  special additives to improve workability, water retentivity, open time and adhesion. No vertical slip. Especially suitable for fixing tiles directly on brickwork substrates and very uneven walls .

  • It reduces tolerance to substrate flatness. No need for plastering. Saving materials and workforce.
  • Non slip.
  • High water retentivity.
  • High  tensile adhesion strength and mechanical  strength.
  • It allows up to 2 cm of thickness.

Laying of small and medium ceramic tiles of medium and high absorption in interior walls and  floors. On very uneven substrates (thick bed tile adhesive). No need for a previous plaster smoothing coat. Especially suitable for fixing tiles directly on brickwork substrates.

BEYEM DIR is suitable for:

  • Bricks.
  • Cement based renders.
  • Cement  based substrates.

Substrates must be clean, compact and  free of substances that reduce adhesion such as dust, oil, grease and with no loose material.  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. For additional beddings do not exceed a total of 20 mm  thickness. Do not apply the tile adhesive before  48 hours.

Mix manually of mechanically BEYEM DIR with 4,25-4,75 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. Apply  a thick bed  of adhesive onto the substrate  ensuring that the tile is well pressed-on. On floorings, apply the adhesive onto the substrate and the back of the tile  (double spread technique ).  BEYEM DIR allows 20-40 minutes  of adjustability time  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 10 minutes. 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.

  • On gypsum substrates, apply BEYEM FIJADOR primer before , to avoid contact between gypsum and the cement of the adhesive, avoiding adverse reactions.
  • 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. Grout with  BEYEM JUNTA UNIVERSAL / 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).

Laying of ceramic tiles on brickwork substrates must be carried out with thick bed standard cement based tile adhesive  Beyem Dir 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.
