Spray applied curing membrane for mortars and concrete

Description

Ronacrete Curing Membrane is for use on Portland cement mortars including concrete repair, flooring and renders.  It forms a surface barrier, slowing the rate of moisture loss. The slow loss of water from the surface of fresh concrete or mortar reduces the incidence of cracking and crazing of exposed surfaces, facilitates efficient cement hydration, improves surface hardening and reduces dusting.

 

Ronacrete Curing Membrane may be used when early overcoating or overlaying of the mortar is to be carried out.  Ronacrete Curing Membrane is used in place of damp hessian or polythene and is easily spray applied to surfaces immediately after finishing, when to do so will not damage the surface finish.
