Deactivators or acidifying products are ideal for fabricating washed-out concrete. By washing out concrete, the cement is flushed out and the aggregate particles are exposed. The surface receives a unique, visual effect and is anti-slip. Both products offer different washing depths, a homogenous wash-out image, short drying times, low consumption, and environmental compatibility.
Washed-out concrete can be produced with a positive or negative method. US FormIiner offers the respective surface retarders CR Type N or CR Type PV for both methods.
Our acidification products permit nano- and micro washing outs or rather acidification up to 0.05 millimeter in fresh and old concrete. With deactivators, washing outs ranging from 0.1 to more then 2 millimeters are feasible. You can find details on the washing depths in our brochure on surface retarders.
