Details

Single-component acrylic-based elasto-plastic sealant in aqueous dispersion for overpaintable sealing of cracks, fissures and expansion joints between façade elements with a maximum working elongation of 10%.

Instructions for use

  • The sides of the joint must be solid, clean and consistent.
  • The dimensions of the sealing must be minimum of 6 x 6 mm and maximum 15 x 7.5 mm. On deep expansion joints, insert the backfill sealant.
  • A 2.1 does not require primer: on very absorbent substrates, first apply with a brush A 2.1 diluted with water.
  • Cut the nozzle according to a diameter proportional to the size of the joint. Inject an excess amount of A 2.1. Smooth out with a spatula dampened with “Smooth” smoothing agent before the surface film formation begins. Apply a certain pressure in order to obtain a void-free filling and complete adhesion of the sealant on the sides of the joint.

Storage

Store in a dry place, protected from frost and heat. In the original packaging it is kept for at least 24 months.

Warnings

  • Not suitable for sealing that can be walked on or constantly exposed to water.
  • Do not apply in case of risk of rain.
  • Do not apply in the case of heavily stressed joints.
  • Do not store or apply at temperatures below 0 °C.
  • Clean tools with water if A 2.1 is still fresh; mechanically and with organic solvents if hardened.

For sealing cracks and applications on joints between vertical or horizontal construction elements, provided there is no continuous water stagnation. It can be painted after hardening. Excellent adhesion on porous substrates, even damp ones: plasterboard, plaster, masonry, wood, fibre cement, concrete.
