WHAT IS A LIQUID APPLIED ROOFING MEMBRANE?
Liquid Applied Roofing Membranes/Fluid Applied Roofing Membranes are monolithic, fully-bonded, fluid-based coatings that have the capability of being fully or locally reinforced in transitional areas on a roof. These liquid applied membranes, also known as fluid-applied membranes, can be applied over various substrates such as concrete, brick, wood, mod-bit, TPO, PVC, EPDM and many other surfaces. When these coatings cure, they form a rubber-like, elastomeric, seamless waterproofing membrane with no cracks, gaps or voids to allow the ingress of water. The superior conformability and customization of liquids allow for easy application of roofing systems to complicated details and penetrations with little to no waster.

LIQUID/FLUID APPLIED ROOFING PRODUCTS & SYSTEMS
SIKALASTIC ROOFPRO: FULLY REINFORCED LIQUID ROOFING & WATERPROOFING
Our cold liquid-applied membranes combine a moisture-triggered, single component polyurethane resin with either Reemat fiberglass or polyester fleece reinforcement to create a highly conformable, self-adhering and self-terminating roofing/waterproofing membrane resistant to rainfall and ponding water within minutes of application.
Reemat fiberglass mats are high tensile-strength reinforcing mesh that eliminates visible reinforcement overlaps and conforms to many flashing conditions without special cutting and fitting. Non-woven polyester fleece reinforcing mesh has a defined-thickness which allows a single-pass, wet-on-wet application, ideal for many flashing conditions with sharp bends and angles.

SIKALASTIC ROOFCOAT: ROOF COATINGS
Our single component coatings utilize local reinforcement to create a highly conformable, self-adhering and self-terminating roof coating resistant to ponding water. Good for cool, reflective reroof and roof recover/extension applications.
