TDS For Polyrelease
- Step by Step
Action
The alkali reactive chemicals in Polyrelease promote a water repellent interface, which protects both steel and timber formwork, whilst ensuring concrete a smooth, hard and uniform finish with reduced incidence of blow holes. Polyrelease has no negative effect on the properties of concrete nor will it impair the adhesion on subsequent surface treatment when applied at the coverage rates. Polyrelease will not stain the concrete surface.
Application
Forms should be clean and rust free. Apply a thin coating of Polyrelease with a fine brush or a spray unit before casting. Excessive application should be avoided as it is self migrating. Whenever new timber or plywood is used, an initial spray coat should be applied to seal the pores on the surface.
Coverage
The coverage rate of Polyrelease is 30-70 m2/L. this depends on the surface density and porosity of the formwork.
