Making of joints between construction elements, either vertical and horizontal. Once cured it can be painted and ensures good resistance to weather. Excellent adhesion on smooth and porous surfaces: glass, rigid plastics, metal substrates, plasterboard, plasters, masonry, wood, fibre cement, etc. It does not corrode metals, does not reduce its initial volume and keeps its elasticity even at low temperatures without stressing the sides of the joint. In the transparent, crystal clear version, it is particularly suited for invisible bonding with high mechanical strength.
