WATER-BASED, DECORATIVE, WATERPROOFING, FIBRE-REINFORCED COVER FOR THE PROTECTION OF CONCRETE. ELASTOLIQUID STRONG is recommended for covering and waterproofing concrete roofs. It can also be used for waterproofing concrete terraces before grŔs or clinker tiles applied on, and, generally, on complex geometry surfaces, where polymer bitumen membranes cannot be applied. ELASTOLIQUID STRONG is suitable for waterproofing terraces with floors made of: concrete, polymer bitumen membranes self protected with mineral slate granules. On old polymer bitumen membranes or bitumen coverings, the adhesion varies according to the degree of ageing of the covering itself. In the above case it is necessary to check the adhesion of ELASTOLIQUID STRONG prior to application.
