Product Description
SonaSpray "fc" is a spray-applied acoustical texture
designed for a wide range of project types. SonaSpray "fc"
provides an attractive, high performance solution to acoustical and
lighting design objectives in both new construction and renovation
projects. Typical installations include schools, churches, auditoriums,
passenger terminals, libraries, detention facilities, cafeterias, offices,
hotels and condominiums.
SonaSpray "fc" is available in White, Arctic White and
specially matched colors.
Acoustical Performance
As tested by an NVLAP accredited acoustical laboratory per ASTM
C-423, SonaSpray "fc" provides an exceptionally high noise
reduction coefficient (NRC). A typical installation of 1/2" thick on
solid backing has an unequalled NRC of .65.
Substrate Compatibility
SonaSpray "fc" conforms to any surface configuration
such as barrel vaults, concrete "T", corrugated decks, pan
construction and other complex surfaces. The high performance adhesive
bonds to virtually all construction materials including gypsum board,
plaster, wood, metal and concrete. Some surfaces (water-stained ceilings,
wood and oxidized metal) require sealing to prevent migratory staining of
the SonaSpray "fc".
Durability and Maintenance
The strong, resilient bond of the adhesive used to apply
SonaSpray "fc" provides a remarkably durable surface. SonaSpray "fc"
resists impact and abrasion without cracking or spalling typical to many
cementitious or plaster-based materials.
In areas where even higher abrasion resistance may be desirable,
SonaSpray "fc" Dura-k may be specified. This product provides
even greater bond and compressive strength without reducing the acoustical
performance.
