INSTRUCTIONS FOR USE

Surface preparation:
The surfaces must be free of dust, loose particles, oil and ice.
Moisten dry surfaces with water mist (only above 0 °C) to accelerate curing and improve adhesion.

Balloon preparation:

Shake the cylinder at least 20 times.

Hold the cylinder in an upright position with the valve facing up.

Screw the cylinder onto the gun while holding the adapter in place with your fingers.

The foam output can be adjusted with the trigger of the gun and the adjustment screw.

Installation on the board:

Apply the adhesive foam to the back side of the board in parallel strips 3-4 cm from the edges + one center line strip (row spacing up to 25 cm).

Wait 2-3 minutes.

Push the tile to the wall.

The plate position can be adjusted within 5 minutes.

One cylinder is enough to fix up to 10 m² of tile surface.

Window sill installation:

Check the flatness of the substrate and use shims for support.

Place the foam 3-4 cm from the edge.

The window sill must be pressed with a weight until the adhesive foam solidifies.
