INSONO AF3-47 is composed of self-adhesive elastomeric bitumen with an exposed non-woven polyester reinforcement. The underside is surfaced with a protective release film. INSONO AF3-47 is designed for use under ceramic tiles but can also be installed with wood flooring or vinyl planks. INSONO AF3-47 offers sound damping, crack insolation through a concrete slab and waterproofing.
Prepare surface with INSONO AF3 Primer, ELASTOCOL® Stick H2O or RESISTO H2O Primer, follow drying times indicated on the primer data sheet then install the INSONO AF3-47 membrane. Apply the polymer-modified mortar and install the ceramic tiles. For installations where waterproofing is required, waterproofing strips, such as SOPRASEAL® Stick 1100 must be installed prior to INSONO AF3-47.
