Wecryl 821 is a fast-curing, dust-suppressing, ultra-low viscosity resin with very good penetration on mineral substrates. The product reliably fills cracks and pores and ensures very good substrate stabilisation. Wecryl 821 is ideal for improving surface strength on porous substrates or after the substrate has been pre-treated with a scarifier.
2-component, fast-reactive / fast-curing PMMA-based (polymethyl methacrylate) water repellent
is available in the following standard colours:
Wecryl 821 is used as a stabilising primer on critical substrates. For use on substrates with increased porosity, reliably fills pinholes and pores. It increases the wear resistance of mineral surfaces, and also reduces water absorption and soiling tendency. Carbon dioxide diffusion is reduced and water vapour diffusion is ensured. Ideally Wecryl 821 should be used after the surface has been treated by scarifying or shot blasting. Can also be used on high-compacted concrete and ZE screed. Fills cracks up to 3 mm wide.
