HEBAU retarder papers are applicable for the production of prefabricated decorative concrete, such as paving slabs/tiles, stair treads, steps and other pieces of concrete with an exposed aggregate surface.
HEBAU retarder papers work well with different production setups and concrete mix designs (from zero-slump to wetcast). The paper has a plastic-coated, waterproof reverse side and the front side is coated with a reliable concrete surface retarder resp. deactivator. HEBAU retarder papers are easy to use and come in a wide range of different exposure depth types and sizes, as sheets or on rolls.
