Applications & Uses

Application Procedure

The surface should be structurally sound, clean, dry, leveled and free from dust, curing compounds, grease and other loose debris. Keep container closed when not in use.

Apply MASTERFIX 770 evenly with a brush or roller evenly on both surfaces and wait until solvent has fully evaporated. After the evaporation of solvent in adhesive, assemble the surface by applying normal hand pressure. Special care must be taken on the edges and adhesive must be evenly applied.
