Retarder Papers are a user-friendly, consistent system for the production of exposed aggregate surfaces on horizontal applications in face down precast concrete production. Controlled depth is achievable from very fine exposure (RSE Paper 01 and SE Paper) to more pronounced exposure (HEBAU WB-Paper) inbetween exposure/texturedepths of approx. 0.5 mm to 8 mm. The backing of the papers is colour-coded for easy identification of the specific grades.
Retarder papers are particularly suitable for the production of precast paving, artificial stone and other decorative concrete elements. Suitable for use with dry, semi-dry, wetcast or self compacting mixes.
Very simple and reliable application, even available in micro-exposure version, very flexible exposure types and sizes available.
