Instructions for use

The surface preparation

Remove the residues of emulsion and oil paints as well as loose grains of sand using a spatula. The surface should be clean, closed and free from grease.


High-absorbed surfaces and exposed to moisture should be grounded with the priming emulsion

Mortar preparation

Pour the package contents to cold water in a ratio of 5 to 5.5 litres of water per 25 kg bag and mix thoroughly, preferably with a mechanical stirrer. Then wait for approximately 3 minutes and again mix well. The time of mortar application approx. 3 hours.


In order to stick the thermal insulation of polystyrene, apply the adhesive in points using no less than 12 points on 1m², the volume of not less than 120cm³ each. Additionally, on the polystyrene boards, apply mortar on the edges to form a frame around the board of a width of 3 cm and a thickness of approx. 1 cm. Stick the insulating boards up to 20 minutes after the mortar has been applied on the polystyrene. The insulating boards arrangement can be adjusted up to 10 minutes since they have been sticked. Performance: polystyrene sticking – approx. 4 kg/m². The temperature of the performed works: from +5ºC to +25ºC.
