DLX K15 Basecoat for sticking foamed polystyrene boards and embedding mesh

In the ARSANIT DLX K-15 system it is used for sticking foamed polystyrene boards on typical mineral grounds – that is bricks, traditional cement plaster or cement-calcareous, concrete, cellular concrete, or in reinforced layer. The plaster can be used for filling little depletions.

Glue mortar DLX K-15 is a dry mix of high quality cement, mineral fillings and polymer modifiers. Glue mortar DLX K-15 is very elastic, with improved adhesion, high steam-permeability, has high efficiency and is easy in use. DLX K-15 mortar can be used indoor as well as outdoors.


Dry mixture of glue mortar pour into about 5-6 litres of water and mix it (manually or automatically) until You get a homogeneous mixture. The glue is ready to use after 5 minutes and after mixing again. The glue mortar should be used up within 2-3 hours.

The temperature of work should be from +5°C to +25°C. The ground, on which DLX K-15 is used should be dry, clean, fat-free and free of any other alien materials. Very absorbent ground should be stained with ACRYLIC GROUND STRONGER AG-015. If the ground is difficult, unstable, there should be adhesion try made. DLX K-15 should be put onto foamed polystyrene with the trowel, circulate the mortar on the whole surface of the board or use the edge-point method. Directly after putting the glue, put the board to the ground and bang it until it gets the desired form. Choose the amount of mortar so that 60 % of the board is sticked. When the mortar is dried, attach foamed polystyrene boards with the plastic connectors. The reinforced layer is made by stringing the DLX K-15 mortar onto isolation layer and to lute the glas fibre net in vertical lanes.

Sticking polystyrene boards depending on the ground is 3,3 – 5 kg/m2
Making the reinforced layer is 3 – 3,5 kg/m2.
