Beyem Junta Universal

Polymer-modified tile grout mortar (CG2 AW) with  bacteriostatic and fungistatic properties for joints up to 20 mm.

BEYEM JUNTA UNIVERSAL  is a polymer-modified, colored  tile grout mortar formulated with cement, selected aggregates, special additives, synthetic resins and mineral pigments. BEYEM JUNTA UNIVERSAL  incorporates a large spectrum biocide that provides algaecide and fungicidal properties. For joints up to  20 mm. Indoor environment quality. Classifed as  A+ class according to Décret nº. 2011-321 (France).

  • Wide range of colours.
  • Low water uptake.
  • High hardness.
  • High abrasion resistance.
  • Algicidal and fungicidal effect.
  • Easy to use. Easy to clean.
  • Excellent  workability. Great plasticity.
  • Mould-resistant.
  • Very low VOCs  emissions.
  • Smart microencapsulated pigment (black color)

Grout mortar for joints up to 20 mm. Suitable for all types of ceramic tiles, natural stone, glass mosaic, marble , etc. For interior and exterior situations to walls and floors.  Specially suitable for use in wet areas (swimming pools).

BEYEM JUNTA UNIVERSAL is suitable for:

  • Cement  based substrates.
  • Cement tile adhesives.

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 dry and free from any rising damp. Empty joints must be dry and clean in all their length and depth. Wet the joints with clean water before application when using very porous ceramic tiles in high temperatures and in the presence of wind. Before starting the application, temporary porefiller BEYEM TAPA protects matt, porous and non-porous ceramic from possible pigment stains.

Mix manually of mechanically BEYEM JUNTA UNIVERSAL  with 1,45l per bag (5Kg) of clean water until a homogeneous, creamy and lump-free paste  is obtained. The amount of mixing water can be adapted in order to facilitate the application; however, an excess of mixing water may cause a visible shrinkage of the grout. Let the mix stand for 5 minutes before application.  Fill the joints completely using the appropriate trowel or rubber float, making sure the joints are completely compacted, with no unevenness. Remove excess of BEYEM JUNTA UNIVERSAL, while still fresh, from the surface moving the float diagonally across joints.

When the mixture loses its plasticity and becomes matt, clean excess of grout mortar with a damp hard cellulose sponge  or rubber float working diagonally to the joints.  If cleaning is carried out too early (when the mixture is still plastic), the grout may be dragged from the joint leading to colour variation. On the other hand, if the grout has already hardened, it is necessary to clean the surface mechanically, which could scratch the surface of the tiles.

  • 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.
  • When applying BEYEM JUNTA UNIVERSAL in extremely hot, dry or windy days, it is recommended
  • to wet the joints after several hours.
  • In outdoor, joins should be protected from rain until completely drying of grout mortar.
  • Adhesive should normally be left for at least 24-48 hours before grouting.
  • Use BEYEM DESIN  to clean up stained tiles (wait at least 15 days after application) . Make sure the product does not damage the tile. Do not use on grouted joints.
  • If the grout is required to be completely impervious to water  or chemically resistant, use BEYEM JUNTA EPOXY.
  • For porcelain tiles and natural stone BEYEM ADIFLEX can be added to the grout mortar, because with the addition of this product a transverse deformation S1 is achieved.
