weber pluscalc is a hybrid interior plaster with lime-like properties. Consisting of fractionated sands and a CO2-reduced special binder, it can be used in all interior areas on all types of masonry, concrete with a bonding layer or as a plaster base coat, especially in biological-ecological house construction and for demanding renovation work in listed buildings. It can be used as a base coat and ready-to-use plaster, including damp rooms, such as domestic kitchens and bathrooms, as well as on ceilings and walls. All mineral final coats from Weber, as well as all solvent-free paints, can be applied on top of weber pluscalc, which is easy to apply and suitable for both smooth and felt-textured finishes. Its physical building properties, such as good room humidity regulation and vapour diffusion openness, provide a healthy and comfortable living climate. Thanks to its high pH value, weber pluscalc is mould-inhibiting. Due to its specific low-stress hardening process, it offers the best crack resistance.
