Seawalls, concrete piers, pilings and more offer unique challenges for both cleaning and preservation. Creto Deep Clean cleaner is environmentally friendly, does not harm sea life, but has the ability to remove atmospheric dirt and mineral deposits. Creto Deep Penetrating Sealer (DPS) penetrate deep into the concrete substrate to first purge chlorides and other contaminants, then seals the capillary system around the reinforcing steel to prohibit oxidation of the metal. Creto TopSealwater repellent can then be applied to seal the top surface of the concrete without changing its profile.
