   PACKAGING           Washable, Bridges Hairline Cracks,Waterproof and Mould Resistant

                       ELASTAKOTE is a premixed one pack heavy duty elastic water based acrylic coating that is easily applied to
                       form a resilient barrier over concrete and masonry roofs and walls. Elastakote will waterproof the substrate and
                       protect it from weather and atmospheric degradation. ELASTAKOTE will remain elastic and will bridge and seal
                       hairline cracks.
                       A durable elastic coating for the protection of exterior and interior concrete and masonry roofs and walls.
                       ELASTAKOTE is mould and mildew resistant, bridges hairline cracks and accommodates the movement in the
NO MIXING              substrate protecting it from weather, moisture, UV light, atmospheric chemicals and carbonization of concrete.
