BK-StirolFix Base

Adhesive for bonding EPS boards.

USE

CHARACTERISTICS

PACKAGE

Cement-based adhesive intended only for bonding EPS boards on various mineral substrates. The product is not intended for reinforcement mesh embedding or leveling the entire facade surface. It is used as a component for bonding EPS boards within the BEKATHERM Standard thermal insulation system.

Preparation and application :

The substrate to which the adhesive is applied must be solid, clean, free from efflorescence, oil residues, or paint. Smooth, poorly absorbent concretes, with residual dirt from the formwork, must be cleaned by hot water jet and then primed with BK-Beton Kontakt one day before bonding EPS boards. It is not necessary to apply a primer on new brick walls. In the case of bonding the panels to the walls of aerated concrete, coating with BK-Nivelator is recommended in accordance with the instruction manual. The preparation is performed by adding the powder in about 26-28% of water (6.5-7 l of water for 25 kg of product) until complete homogenization. Leave the mass to rest for about 10 minutes and then stir again to obtain an adhesive of appropriate density, without lumps. The prepared adhesive for bonding is applied over the entire perimeter of the EPS board with the addition of three application points in the middle of the board, in the form of the so-called doughs, approximately 10 cm in diameter. The strips around the perimeter of the board should be applied in a width of min. 5 cm and thickness of 1.5-2.0 cm. After a minimum of 2 days of drying, it is possible to anchor the boards, which is necessary within the system using the BK-StirolFix Base adhesive. See product datasheet for more detailed instructions.
