White cement based mineral adhesive designed for embedding the reinforcement mesh and leveling the entire facade surface. BK-StirolFix White is used as a base coat, i.e. adhesive for reinforcement within the Bekatherm Standard thermal insulation system. BK-StirolFix White can also be used for bonding EPS and MW thermal insulation boards.


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. The prepared adhesive is applied to thermal insulation boards (dotted in the middle and in the form of strips along the edges), and then the boards are bonded to the substrate by lightly pressing. When embedding reinforcement mesh, the adhesive is applied with a serrated steel trowel (tooth size 8-10 mm) on the dedustedstyrofoam surface. The reinforcement mesh (min. 10 cm of overlap between strips) is pressed into such freshly applied adhesive from down upwards. After drying, the entire surface is leveled with a new layer of adhesive, so that the total thickness of the final layer of adhesive is 4-5 mm. The adhesive should be protected from premature drying and freezing. See product datasheet for more detailed instructions.


Optimal weather conditions: Substrate and air temperatures from +5°C to +30°C. Possible to embed reinforcement mesh: after min. 48 hours. Possible to apply finishing coats: after min. 7 days.


about 5-6.5 kg/m² for bonding and about 5-7 kg/m² for leveling,  depending on the quality of the substrate, the type of thermal insulation material used, etc.
