A two component, water based, cementitious modified, polymer rich flexible coating with excellent adhesion to prepared concrete and masonry substrates. The product provides Type A (barrier) protection in accordance with BS 8102: 2009.
RIW Cementflex, when mixed, exhibits a good degree of thixotropy to enable ease of application by brush or spray techniques to give an even finish with no sagging even in vertical situations
It hydrates to form a durable, highly alkaline, permanently elastomeric coating which not only protects the concrete, or other substrates, from water penetration and carbon dioxide diffusion, but also accommodates movement in cracks
The elastomeric coating maintains its flexibility under permanent immersion and when exposed externally
Non-hazardous and ideally suited for application in confined spaces
Must be applied to damp substrates
Non-toxic when cured
Applied by spray – brush or trowel applications can be employed but care must be taken to ensure that no air is trapped into the surface
