RB 7.23 Vertical Surface Retarder-Plus

RB 7.23 Vertical Surface Retarder is a water based concrete surface retarder which is applied directly to form work, either concrete or steel, prior to the pouring of concrete.

It is recommended to be used on concrete with strengths of 20 MPa and over.

The normal hydration of cement in contact with the treated form work is delayed for a depth of 3-6 mm whilst the underlaying concrete hardens.

RB 7.23 Vertical Surface Retarder is supplied in 20lt containers.

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 and can be used on either vertical or horizontal surfaces.
  • Can be used in conjunction with ROCKBOND SURFACE RETARDER–PLUS (RB 7.17) to provide a consistent exposed aggregate surface to both the horizontal and vertical surfaces of concrete with strengths of 20 MPa and over.
  • It provides an economical surface preparation to vertical concrete that will be overlaid with a plaster render.
  • It is also used to form a mechanical key to vertical construction joints eliminating the need for expensive scabbling.
