- Permanent elasticity.
- Elongation at break 500%.
- High mechanical resistance.
- Zero shrinkage.
Surfaces must be dry, clean and free from grease. Application temperature from +5 °C to +40 °C. Cut the end of the cartridge or 600 ml package and screw the nozzle on the cartridge supplied with it. Insert the cartridge or package into the caulking gun and fill the nozzle with glue by pressing the trigger on the gun several times. The joint depth should always be in the correct relationship of the joint width. A general rule is the ratio of joint depth to the width of the joint with a joint width up to 10 mm is 1:1, with a minimum of 5 mm in width and depth. For joints wider than 10 mm, the depth is the width divided by 3 plus 6 mm. Maximum joint width is 35 mm.
