MATOX 205S – cement adhesive for insulation panels and reinforcing mortar (Premium)

MATOX 205S mortar is designed to insulate external walls of the buildings. 205S mortar is used for fixing EPS-boards as well as applying the armoured protection layer. It is also suitable for applying façade mineral wool boards. Workability of prepared mortar is over 90 minutes.


Stir MATOX 205S mortar into clean, clear water until it is completely free of lumps. Approx. 7-8 l of water are needed to prepare 25 kg (mixing ratio 3:1). MATOX 205S adheres to all solid, load-bearing, clean, dry and moist surfaces free of substances which ca cause separation. Remove any coatings with inadequate bearing strength.


The ready mortar should be applied with a trowel along the board edges forming a strip of about 1-3 cm wide and a few spots with the diameter of 8 cm. The boards should be fixed tightly one at the other in one surface with the preservation of “brick like manner” of vertical connection. The ready mortar of 5mm-thick layer should be spread along the surface of the boards by means of a smooth long steel float. The glass fibre mesh should be applied on the fresh mortar (10-cm overlaps), and then the second 5mm-thick layer should be applied and smoothed evenly so that the glass fibre mesh should not be visible.
