Concrete roofs are often difficult to waterproof with membranes due to numerous penetrations and complex geometry. KÖSTER Elastic Roof is a liquid applied elastic waterproofing for roofs. It is UVresistant, white and crack bridging. The product does not contain solvents and allows an easy, seamless application.
KÖSTER Elastic Roof is directly applied onto the prepared concrete substrate by roller or spraying. It has very good adhesion to itself (important for overlapping and easy repair) and even damp substrates.
Absorbent substrates are primed with KÖSTER Polysil TG 500.
Always adhere to the specifications in the respective Technical Guidelines.
