Acoustement 40

Detailing all Pyrok Acoustement products is similar to working with stucco and traditional three-coat plaster. Utilize metal and plastic screeds, beads, reveals, J-molding and corner aids; as well as wood trims and Fry Reglets conforming to the thickness of the acoustement desired. All Pyrok Acoustement products can be applied to different thicknesses to achieve optimal acoustical performance.

Acoustement Plaster 20 is gypsum-based and is typically applied to drywall substrates. Drywall should be a minimum 5/8 inch thick and the framing should be 16 inches on center or less. Drywall joints require a level 4 finish.

1. Description
Pyrok Acoustement 40 is a nominal 41 PCF (air-dried density) Portland cement/exfoliated vermiculite spray-applied formulation 100% free from asbestos and mineral fibers, polystyrene, and cellulose. Pyrok Acoustement 40 is highly abuse resistant (impact, abrasion, moisture, hostile industrial environments), has excellent adhesion to a variety of substrates, allows substrates to breath and be cleaned by a variety of methods.

2. Uses
Pyrok Acoustement 40 can be used as a decorative surfacing material or as a combination of these qualities even in conjunction as a fireproofing material.

This material is recommended for exterior exposures where resistance to environmental pollution, rain, corrosion, and spalling is required. It may be used in interior exposures where superior abuse resistance is required.

Typically Pyrok Acoustement 40 is specified for transportation facilities, correctional projects, lobbies, atriums, tunnels, natatoriums, gymnasiums, manufacturing facilities, contact wall areas, and any other area requiring high abuse resistance and sound absorption qualities.

It can also be used on interior surfaces of walkways, hallways, and rooms where a purely decorative finish is desired.

Pyrok Acoustement 40 may also be used on ceilings as a combination acoustical finish and fireproofing material.

Custom integral coloration is available within the limits of iron oxide pigmentation.

3. Packaging
35lb. Kraft paper/polyethylene lined bags
55 bags shrink wrapped pallet (minimum)
1100 bags per truckload

4. Yield
17 Bd. ft./bag (ideal)

5. Applications
Pyrok, Inc. recommends application of Pyrok Acoustement 40 be performed only by approved Pyrok applicators. An approved applicator list is available from Pyrok, Inc.

6. Application Procedures Summary
Pyrok Acoustement 40 may be applied directly to clean, bare steel, clean galvanized steel or a wide variety of unpainted concrete, cement board and other clean, sound substrates. Some substrates will require metal lath. Contact Pyrok, Inc. for verification of compatibility with substrate, suitability of primer and potential requirement of expanded metal lath.

Mix in mechanical type mixer with paddle or ribbon type blades. Use 4-5 gallons of clean, potable water per each 35-pound bag of Pyrok Acoustement 40. Mix 1 to 3 minutes.

Spray-apply using equipment recommended by Pyrok, Inc. Air supply at the spray nozzle shall be a minimum of 40 pounds per square inch. Wet density at the nozzle shall be 70-85 pounds per cubic foot.

Application
Brush or roll-apply a liberal coat of Weldcrete to substrate immediately prior to application of Acoustement 40. Apply a splatter coat covering 60% to 80% of the substrate surface. Allow splatter coat to cure overnight. Successive coats of Pyrok Acoustement 40 shall not exceed 1/4 inch thick per application. Thicknesses that exceed 2 1/8 inches may require metal lath. Contact Pyrok, Inc. to determine if metal lath is required.

Topcoating/Curing
Pyrok Acoustement 40 may be supplied in several integral colors or may be topcoated for more pleasing aesthetic finish or for curing. Consult Pyrok, Inc. for further information regarding suitable topcoating and curing compounds.

Patching or Repair
Contact Pyrok, Inc. or your construction representative for patching or repair procedures.

Cleaning
Wet Pyrok Acoustement 40 may be removed by brushing or with water. Dry Pyrok Acoustement 40 may require scraping or chipping to remove.

Pyrok Acoustement 40 may be steam cleaned or pressure washed after full cure (minimum 28 days).

Storage and Shelf Life
Store Pyrok Acoustement 40 off the ground in unopened, original packages and keep dry. Pyrok Acoustement 40, kept dry, has a five (5) year shelf life.

Warranty
Manufacturer warrants the material to be supplied, agreeing to replace that which has cracked, flaked, dusted excessively, peeled or fallen from substrate, or otherwise deteriorated to a condition where it would not perform effectively as intended for fire protection and sound absorbent purposes; due to defective materials and not due to abuse, or improper maintenance, unforeseeable ambient exposures or other causes beyond anticipate conditions by manufacturer. The warranty period will be 10 years from date of installation. Manufacturer’s liability under any expressed or implied warranty is limited solely to replacement of Pyrok products proved defective and does not include labor or other consequential damages. The suitability of the product for any intended use shall be solely up to the user.

The express warranties set forth herein are in lieu of all other warranties, express or implied, including without limitation, any warranties or merchantability or fitness for a particular purpose. In no event shall manufacturer be liable for any direct, indirect, incidental, or consequential damages resulting from any defect in the material even if manufacturer has been advised of the possibility of such damages.

Packaging: 35lbs bags packaged in paper-polyethylene lined bags.
55 bags shrink wrapped on a pallet,
1100 bags per truckload.
Scrap: See Article 10 and 12, below.

EQ Prerequisite 3 – Minimum Acoustic Performance.**
Acoustement 40 sound absorptive finish contributes to control of reverberation within classrooms.
Acoustement 40 can provide noise reduction coefficients (NRC) up to 0.70 at 1-1/2” thickness.
(measured in accordance with ASTM C423 – Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method).

EQ Credit 4.2 – Low Emitting Materials
Acoustement products give off extremely low levels of VOCs:
Acoustement 40 Finish: 0 gram/liter
(measured in accordance with procedures outline in CPA method 24 “Volatile Organic Content (VOC) of paints and related coatings.” The VOC was calculated using the equation referenced in ASTM D3960 “Determination of Volatile Organic Compound Content of Paints and related coasting”)

EQ Credits 8.1 and 8.2 – Daylight and Views
See comment on lighting efficiency at EA credit 1, above.

6. Sustainable Performance Criteria
No criteria have been identified.

7. Sustainable Composition of Product
No criteria have been identified.

8. Material Extraction and Transportation
Acoustement 40 is processed and shipped from New Eagle, PA. It is composed of the following materials:
-cement (Maryland)
-lime (Ohio)
– vermiculite (extracted in South Africa, processed in Pennsylvania)
The mixture is shipped via truck.
The light weight of the Acoustement system minimizes energy expended in transport.

9. Manufacturing Phase
No by-products are produced in the manufacturing process. No toxic or hazardous materials are used or produced. See MSDS.

10. Construction Phase
Unused finish coat materials can be saved for use on other projects. The light weight of Acoustement 40 simplifies handling and reduces installation energy use.

11. Facility Operations Phase
The acoustical properties of Acoustement 40 ceilings improve the acoustic quality of a space. Studies have shown that building occupants are more satisfied and productive in optimal acoustic environments.

Acoustement 40 is mold resistant.

12. Deconstruction / Recycling
100 percent of demolition debris may be recycled as a fill material or roadway base material.

13. Additional Information
The Acoustement 40 is durable and can last the life of a building with minimal maintenance. The surface can be vacuumed with a stiff bristle brush or water washed. Small smudges can be removed with a soft pencil eraser. If necessary, the Acoustement 40 can be painted without loss of its sound absorbing properties.

14. Certification
The information provided herein concerning the sustainability of Acoustement 40 Acoustic Cement is true, correct, and verifiable.
