Product Description
7.24 Form-Tard PLUS is an environmentally friendly water based concrete surface retarder which is applied directly to formwork + precast moulds prior to the pouring of concrete
Effective on moulds or formwork made of steel, wood, or dense composite materials
The normal hydration of cement in contact with the treated formwork is delayed for a depth of 3-6 mm whilst the underlaying concrete hardens normally
USES
- Used to produce a uniform depth of exposed aggregate finishes to in-situ or precast concrete poured in steel, timber or plywood moulds or formwork + can be used on either vertical or horizontal surfaces
- Can be used with 7.17 SURFACE RETARDER–PLUS to provide a consistent exposed aggregate surface to both the horizontal + vertical surfaces of concrete with strengths of 20 MPa+
- Provides an economical surface preparation to vertical ‘off the boxing’ concrete that will be overlaid with a plaster render
- Used to form a mechanical key to vertical construction joints, eliminating the need for expensive scabbling
