Washing Depths

Our products for the acidification of concrete surfaces facilitate nano and micro washing and/or acidification up to 0.05mm in new and old concrete. With deactivation, washing from 0.1 to 2 mm can be realized in exposed concrete. You can find details about washing depths in our brochure on surface retarders
