Active gel contains ingredients and active acids to obtain micro-exposure on previously cured concrete surfaces. On Acid stained floor Active gel is used to create decorations or light sandblastings on special portions of floor such as: along the edges of the steps in order to make them non-slipping or to remove acid and obtain frets and decorations. On SassoItalia® floors Active gel is used to re-treat any surface where the “washedstone” effect is not as desired or where the surface deactivator was incorrectly applied. Active gel is also used as surface preparation product for Micro-topping and Decorative epoxy.
