SURFACE PREPARATION

Ensure that the surface is smooth, clean, dry, matte enough to allow adhesion, strong and self-supporting. Start
the application of Optimix Thermal Insulation Adhesive Mortar a minimum of 4 weeks after the application of
sub-plaster or rough-cast. Dampen the absorbent surfaces like gas concrete in particular during the application.
Scrape the blistering and flaking sections of the previously painted surfaces, and fill the cracks on the surface with
repair mortars. Notch the old painted surfaces to prepare them for holding the product.

MORTAR PREPARATION

Add clean and cold water slowly into Optimix Thermal Insulation Adhesive Mortar, and mix for approximately
10 minutes with a low speed mixer until the mixture is free of pellets. Adjust the required water amount according
to the weather conditions. Rest the mixture for 5 minutes and mix again. Readjust the consistency by adding
water, if required. Consume the prepared mixture within 2-2.5 hours according to the weather conditions. Do not
reuse the hardened material by reconstituting.

APPLICATION

Apply Optimix Thermal Insulation Adhesive Mortar on prepared surfaces as 3 trowel sized points with equal
distances to the center and as a 4-5 cm thick line along the edges of the insulation plate. Notch with a 8x8 mm
toothed steel trowel on smooth surfaces.
If the plate is rock wool, the plate can be primed by applying adhesive on its edges and central points as a thin
layer. After this step, standard adhesive application can be performed.
Avoid applying adhesive on sides of the plates. Adjust the thickness of the adhesive layer based on the
smoothness of the application surface. Affix the plates upwards by applying slight pressure on the application
surface starting from the subbasement profile at the bottom in a way that each one touches the other. Avoid
overlapping the joints of insulation plates and place the plates irregularly. Ensure a leveled surface is created by
pressing firmly with the help of a floating rule. Ensure there are no gaps between the plates, and close any gap
with a piece cut from the same plate at the right thickness.
Ensure that the ambient and surface temperatures are between +5 °C and +30 °C during application and drying.
Avoid application under conditions including direct sunlight, rain, and strong winds. Protect the product against
freezing until set. Clean the used tools thoroughly with water after application.

MIXING

Mix 25 kg Optimix Thermal Insulation Adhesive Mortar with 5-6 L of water depending on the weather
conditions.

DRYING TIME

Dowel the plates and start the top coat application at least 24 hours after they are fixed. Full-dryness:
2-3 days Since drying occurs physically with the evaporation of water, low temperatures and high relative
