Wecryl 121



Primer, ultra-low viscosity

Brief Description

Wecryl 121 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 121 is ideal for improving surface strength on porous substrates or after the substrate has been pre-treated with a scarifier.

Material

2-component, fast-reactive / fast-curing PMMA-based (polymethyl methacrylate) water repellent

Application

Wecryl 121 is used as a stabilising primer on critical substrates. The product increases the wear resistance of mineral surfaces and reduces water absorption as well as soiling tendency. Since only one application is required, this product offers a cost-effective option for providing unprotected concrete surfaces with concrete protection to OS3. Carbon dioxide diffusion is reduced and water vapour diffusion ensured. Ideally Wecryl 121 should be used after the surface has been treated by scarifying, bush-hammering or shot blasting. Can also be used on high-compacted concrete and ZE screed. For use on substrates with increased porosity, pinholes and pores. Fills cracks up to 3 mm wide.
