Ratamate: Film-type retarder for concrete surfaces
Ratamate is made of PET film, coated with a polyester-based material. When it contacts an unhardened
concrete surface it inhibits the hardening of surface mortar. It can then be washed off with pressurized water to provide a surface with exposed aggregate suitable for a concrete joint or decorative design.
Features & Benefits
- Uniform Depth – Provides uniform depth of exposed aggregate compared to the processing of a
liquid-type retarder by hand.
- Long lasting – The retarding effect lasts for a long time (up to 1 month with the film in place).
- Water Resistant – The retarding ability is unaffected even if the mold with Retamate is wetted by
rain or water before casting.
- Apply to any angle – It can be applied to any surface angle (horizontal, slanted or vertical)
without any negative effect.
- Cuts Easily – Retamate cuts easily and the retarder does not drip, so a partial aggregate can be
exposed.
