One-component dispersion based white sealant


Alltek Acrytek is a white, water-based single component acrylic sealant.
It is used both inside and outside.


  • Alltek Acrytek is an acrylic compound used to treat seals between masonry units with moderate traction restriction.
  • It is also used as a sealant for window sills, door frames, roller blind boxes or for simple treatment of cracks.
  • Alltek Acrytek can also be used to glue expanded polystyrene onto absorbent supports.
Typical spreadability 310 mL enables performing 19 metres of a 4 X 4 mm seal

  • Bare concrete and masonry, bricks, terracotta floor tiles, plaster, plaster blocks, plasterboard panels and derivatives, rigid plastic materials, wood and anodised aluminium.

Preparation of substrate:

  • The substrates, preparatory work and application conditions must be compliant with applicable building trade regulations (e.g. DTU) and standards.

Application tips:

  • Remove the old compounds or paints on the seal if required and make sure the support is dry, free of dust and grease (if necessary, clean with isopropanol).
  • Seals performed on porous supports (concrete, untreated wood, plasterboard) will be pretreated by applying diluted Alltek Acrytek in advance (1 to 4 parts water for 1 compound part).
  • Ensure that the seal dimensions are at least 5*5 mm (length* depth) inside and at least 10*8 mm outside. The width of the seal must not exceed 30 mm, its depth must be approximately equal to half its width.
  • Protect with masking tape any edges of the seal not aimed to have the compound applied.
  • Apply the product using a pistol adapted so as to fill the seal (or the crack) then smooth out the seal with the assistance of a spatula wet in soap and water. Therefore, the joint will appear smooth and the compound will adhere better onto its support.
  • Immediately remove the masking tape.
  • Protect the seal from bad weather and condensation and water spray up until skin formation.


  • Ensure adequate ventilation to remove excess moisture and accelerate drying.
