Polyurethane mastic

The POLYURETHANE MASTIC is a one component sealant of permanent elasticity and adequate consistency to be applied with manual or pneumatic extrusion pistol, and smoothed with a spatula. In reaction with atmospheric moisture, the material achieves its elastic final state, similar to rubber. Classified as 1 Category Elastomer according to Norm NF P 85-305.

Remove the seal of the bottom of the cartridge. Screw the plastic mouthpiece previously cut in bevel form of 45º, according to the width to apply. Apply by pneumatic or manual pistol, trying to maintain the mouthpiece to the same depth and inclination in order to avoid air occlusion. If necessary, smooth with a spatula moistened in soapy water.
