Application instructions

Surface preparation. The surface of the insulation boards must be free of dust, grease and loose or foreign elements. The boards shall be properly fixed to prevent any movement while the mortar is still fresh.

Mixing:. The material is mixed only with clean water, between 3.75 and 4.25 litres of water per each 25 kg. bag. (16 ± 1%), using a low speed mixing drill. Allow the material to rest for 5 minutes after mixing. Re-mix and the material is ready for application.

Application: Apply with a trowel at a rate of 3 to 4 kg/m2 (about 2 mm thick) and while it is still fresh, place the reinforcement fibreglass mesh (160 gr/m2, 0.5 cm mesh) and press into the mortar. Apply a second coat also about 2 mm. thick once the first layer has set to sufficient consistency for about 8 to 24 hours, depending on application conditions.
Final texture is obtained with a trowel or sponge float.

Finish: For providing a decorative colour finish MAXSHEEN smooth or textured can be used.
Allow at least 5 to 7 days, depending on ambient conditions, for the mortar to dry completely before applying the decorative finish.
.
Surface preparation for placing insulation boards. The insulation boards can also be fixed using CONCRESEAL TH, as well as other fixing products in our range such as MAXKOLA FLEX, or MAXFIX. Other fixing methods whether mechanical or bonding agents can also be used.
The surface to be treated must be free of dust, grease and loose or foreign elements. Apply with a toothed trowel (6 mm) over the whole surface and place the insulation boards. Allow at least 24 hours with auxiliary fixing elements before application of exterior coating.
