weber.cal 176 is a mineral lime lightweight render for interior use. It is particularly suitable for highly insulating masonry substrates with low compressive strength. Thanks to its reduced modulus of elasticity, weber.cal 176 offers a high level of crack resistance. All mineral top coats from Weber, as well as solvent-free paints, can be applied on top of weber.cal 176. Its building physics properties, such as good indoor humidity regulation and high vapour diffusion openness, provide a healthy and comfortable living environment.
