Air-Shield LM by W.R. Meadows is a single-component, liquid-applied, water-based, polymer-modified air/vapor and liquid moisture barrier formulated to prevent the transmission of air and inhibit vapor and moisture from passing through porous building materials. The liquid-applied characteristic of Air-Shield LM makes for a simple application, while it is also a sprayable product. It is suitable for both new construction and restoration projects. To assist with joint treatment of exterior sheathing panels when using Air-Shield LM or Air-Shield LM (All Season) fluid-applied membranes, W.R. Meadows has published a set of installation instructions. This document outlines recommended instructions complete with graphics that help reinforce the guidelines.
