Beyem Gros

Concentrated premixed mortar for traditional thick bed tiling.

About this product

BEYEM  GROS is a concentrated premixed mortar formulated with cement and special additives to improve workability and adhesion of mortar.  Especially suitable  to be mixed with suitable aggregates on site.

Benefits
  • It reduces tolerance to substrate flatness. No need for plastering. Saving materials and workforce.
  • High water retentivity.
  • It works more easily compared to mixed products  on site.
  • Non slip.
Use

Preparing  mortar  for traditional thick bed tiling on brickwork and screeds floors  using small and medium ceramic tiles of medium and high absorption in interior walls and  floors. BEYEM GROS  is a semi-finished mortar. 

Substrates

BEYEM GROS is suitable for: 

  • Bricks.
  • Cement based renders.
  • Cement  based substrates.
Preparation of 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. 

Instructions for use

Mix 1 volume of BEYEM GROS with 4 volumes of sand. Add clean water and mix 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 back of the tile  ensuring that the tile is well pressed on substrate. Adjust with a slight sliding or twisting action to get a good contact of the whole surface of the tile. 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. 

Cautions and recommendations
  • 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).
  • Para grandes espesores, se deben utilizar morteros de regularización en paramentos verticales y pastas niveladoras o morteros de recrecido en aplicaciones horizontales.
  • Para conseguir un  perfecto asentamiento del material deberá evitarse el tránsito sobre las baldosas durante 3 o 4 días después de la aplicación.
  • The temperature, ventilation, and absorption of the substrate and covering materials, may vary the adhesive workability and setting times.
