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, swimming pools, gymnasiums, cafeterias, libraries, music rooms,
auditoriums, churches, passenger terminals, detention facilities, offices,
hotels and condominiums, etc.
As tested by a 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, or at 1" of .90.
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."
The strong, resilient bond of the adhesive used to apply SonaSpray "fc"
provides a remarkable durable surface. SonaSpray "fc" resists impact and
abrasion without the 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
SonaSpray "fc" Dura-k
