It is a cement - based adhesive mortar specially prepared for thermal insulation boards .​​​​​​​​​​​​​​​​​​​​​​

Areas of Use :
• Indoors and outdoors.

• Thermal insulation boards on rough and thin plaster applied concrete , brick , aerated concrete and similar surfaces​ it is used in the adhesion of materials ( EPS and XPS ) .​​​​

Advantages :​

• It is easy to apply and provides good adhesion.
• It is resistant to water and frost.
• It is not affected by temperature changes.

• It does not sag or jump on vertical surfaces .

Preparation of the surface :​​

• Care should be taken to ensure that the application surface is cured.

• The application surface must be cleaned of substances that prevent adhesion such as dust , oil , tar , pitch, paint, silicone , curing material , detergent and mold oils .
• The application surface should be wetted and kept moist.
​​​​​​​ • Defects on the application surface may be removed 24 hours before , depending on the surface depth and structure . It must be corrected with repair mortars.

Preparation of the mortar :​​

• CONTRAST Thermal Insulation Board Adhesive Mortar is added to approximately 5.5 - 6.5 liters of clean water and mixed preferably with a low speed mixer until no lumps remain . It is mixed as follows.
​​​​​​ • The prepared mortar is left to mature for 5 - 10 minutes and is used by mixing again for 1 - 2 minutes.
• The mixture in the container should be consumed within 1.5 hours.

Application Information:

• Depending on the smoothness of the application surface.

Whole Surface Adhesion Method :​​​​​​

Apply CONTRAST Thermal Insulation Board Adhesive Mortar to the entire thermal insulation board with a flat or suitable notched trowel .​​​​​​​​​​​​​​​​ ( This is the preferred method on smooth surfaces ) .

Stripe and Point Applying Method :

Adhering CONTRAST Thermal Insulation Board in strips to all edges of the thermal insulation board and in points in the middle sections with a trowel .​​​​​​​​​ Apply the mortar ( This is the preferred
method on uneven surfaces ).

• A gauge should be used when gluing the sheets during application .
​​​​​​​ • The adhered sheets should be pressed tightly to ensure a good adhesion , and after 24 hours they should be mechanically attached with dowels .​​​​​​

Consumption :​

3 - 4 kg/m 2 (Depending on the application method . )

Attention:

• Avoid application at temperatures below +5 ° C and above +35 ° C.​​​​​​​​​​

• Avoid application in areas that are frozen , at risk of freezing within 24 hours , or exposed to direct sun and wind .

• Never add water or powder to expired mortar.

• To prevent heat transfer , place the thermal insulation boards so that there are no gaps between them .​​​​​​​​

• Be careful not to use sheets that have lost their properties by being exposed to the sun for a long time.

• The sheathing application should not be applied directly on building materials such as pumice or brick , but on rough plastered surfaces .​​
