weber 414 Unirender

weber 414 Unirender is sprayed or manually spread rendering plaster for lightweight aggregate blocks, lightweight concrete and concrete blocks and brick surfaces for large levelling and fillings, e.g. for levelling substrates for insulation, for filling window framework and for thick levelling for interior repairs. The product is also used as a filling plaster in the UniTop three-layer plastering system as well as in the MonoRoc insulation plastering system. The product is fibre reinforced and low water absorptive. It is very water vapor permeable so that moisture in the structure can escape.
