APPLICATION

SURFACE PREPARATION

Joints shall be free of materials that prevents adhesion such as oil, dust, dirt, paint and materials used before.
Since SUTOP® PU MASTIK 40 is affected by water, the joints shall be dry and the product’s contact with water shall be avoided until full hardness is achieved.
Application may be performed without using primer material, too.

PREPARATION of the MORTAR

For manual applications, SUTOP® PU MASTIK 40 is placed inside the gun and injected into the joint without creating an air bubble.
Polyethylene wicks shall be used to prevent the mastic from sticking to the bottom parts of joints.
Thus, material is provided with the capability to move in both directions.
Ensure that the size of the polyethylene wick is greater than 20% – 25% of the joint diameter.
Joint width and depth shall not be less than 5 mm, and joint width shall be equal to the joint depth up to 15 mm.
For larger joints, the joint depth shall be set between 20-25 mm.
