Surface protection systems protect exposed concrete surfaces from moisture, dirt and graffiti. Water especially washes harmful substances, microorganisms and salts into the concrete surface. In the long run, they attack structural integrity and lead to cracks or spalling. RECKLI surface protection seals new and older concrete, either colorlessly or with an added optical effect. Impregnations can be used to treat façade panels, in-situ concrete constructions, concrete blocks and terrazzo flooring.
