A specialist anti-crack render system. A render system for application onto existing flat substrates comprising cement free reinforcing coat and glass fibre reinforcing mesh, suitable to accept a wide range of low maintenance facade finishes offering exceptional levels of weather protection.
A specialist anti-crack render system for use on existing rendered surfaces or external wallboards. It is particularly recommended for use with the Verotec Futur® Ventilated Façade System (specified separately). The system comprises of Sto-Elasto a fibre reinforced, factory batched cement free reinforcing coat, with Sto glass fibre mesh reinforcement embedded to provide additional crack resistance. Sto Rend Flex can bridge existing cracks and board joints without the risk of cracking.
StoRend Flex is a thin coat render system offering exceptional crack resistance that is suitable for application onto existing flat surfaces and is especially suited to use onto either StoVentec render carrier board as part of a StoVentec R rainscreen façade system or onto Sto-Reno Plan board as part of the StoReno system, and can be finished with a range of Sto render finishes, StoBrick, Sto-Resin Brick Slips, Sto-Ecoshapes or enhanced with StoDeco Profiles or StoDeco Rustications. Sto through coloured render finishes are available in a variety of textures and grain sizes, and up to 1100 colours from the StoColor system and StoDesign Architectural Colour Range.
