Series 154


Generic Type

Mastic Waterborne Acrylic

Common Usage

Series 154 is a durable, single-component, water-based elastomeric coating that forms a waterproof film over horizontal or vertical concrete surfaces as well as various types of wallboard, wood and tile. It is an excellent choice for areas that receive light to moderate traffic including balconies, walkways, pedestrian bridges, mechanical equipment rooms and other surfaces such as concrete decks that may require protection from weather or water intrusion. Versatile application characteristics allow Series 154 to be applied neat, as a broadcast system, or mixed with aggregate and either applied as slurry or used as a surfacer or filler. Series 154 can also be reinforced using woven or octagonal mesh inlays where crack-bridging or extra durability is needed.
