Overview
UV-Resistant, Water-Based Elastic Waterproofing (Exterior Walls & Roofs) What it is A one-component, water-based liquid membrane designed for weather exposure, offering an elastic, UV-resistant waterproofing layer for exterior surfaces. Good for Exterior walls and roofs (new or refurbishment) on compatible substrates such as concrete, masonry, stucco and suitable cementitious surfaces. Why DIY customers like it - One-pack, ready to use - UV-stable for outdoor exposure - Helps bridge small cracks with an elastic film - Water-based, low VOC (as stated in the TDS) Before you start (important) - Not for permanent water immersion. - Not recommended for pedestrian traffic. - Avoid roofs with ponding water followed by frost conditions. - Don’t apply on substrates with rising moisture.
