Protek-13 Protective Coating

Spray-On Insulation Protectant

CSI: 09 96 13

Protek-13 is a protective coating for new or previously installed applications of fibrous insulations and coatings like K-13 or fireproofing. Composed of a water-based vinyl-acrylic emulsion containing interlacing fibers, Protek-13 is spray-applied to fibrous insulation resulting in a uniform surface finish that effectively guards against physical damage and airborne contaminants without significantly compromising the acoustic performance of materials underneath.

Typical Projects

Protek-13 is ideal for interior and covered exterior applications where high-traffic and industrial conditions require additional protection from abrasion and airborne contaminants such as dust, dirt, or fumes. Though appropriate for humid environments such as parking garages, Protek-13 should not be specified in areas where the coating is regularly exposed to excessive moisture such as rain or pressure washing.

Protek-13 is Class 1, Class A Fire-Rated and available in standard white and custom colors to meet design requirements.

Protection from

Physical Damage

High-traffic areas are often vulnerable to physical damage from personnel, machinery, birds, and other sources. Protek-13 resists abrasion and prevents “picking away” of the fibers, extending the life of your fibrous insulation.
Additionally, Protek-13 provides superior hiding characteristics making it a great solution for previously installed applications of K-13.

Protection from

Airborne Contaminants

Dust, dirt, grease, and fumes are present in almost every industrial environment. The firmer, more uniform surface of Protek-13 significantly reduces the accumulation of these airborne contaminants. For clean-up, Protek-13 can easily be swept with a broom, blown clean with compressed air, or lightly washed with water (no scrubbing).

Sound Control

Protek-13 provides a protective coating for K-13 Thermal and Acoustical insulation without significantly affecting the acoustical performance of the material underneath.

The following test was conducted by spraying two separate thicknesses of Protek-13 over 1.75″ of K-13 Thermal and Acoustical insulation. System 1 was applied in a standard coating, covering 96-98% of the K-13 underneath. System 2 was a heavy-build covering 99-100% of the underlying K-13.

ASTM C 423 - Sound Absorption (NRC)
All acoustical testing was performed by an NVLAP-accredited laboratory. Testing available on request.

Custom Colors Available

Protek-13 is available in standard white as well as specially-matched custom colors.
