Application Steps

Step 1

The substrate must be dry, cleaned of dust, loose particles, oils etc. The cleaning of joint with paint brush or special brush and blowing with compressed air is recommended.

Step 2

The cartridge is placed in the special gun and then the nozzle is cut sideways not to penetrate, but just to touch the side of the joints.

Step 3

Applied, placing the cartridge 450 angle to the axis of the joint. Apply by hand or air gun (maximum required pressure: 3,5 kg).

Step 4

While is still fresh the silicone smoothed with a spatula.

Step 5

Avoid entrapping air.

Step 6

To avoid unwanted spots on the side of the joints, place paper tape and remove it immediately after sealing (before membrane formation) while the sealant is still soft.

Step 7

Joint width/depth ratio should be 2:1.

Storage

Stored in the unopened, original package in a dry place at temperatures between +10οC and +25οC for 15 months from the production date.
