Acoustement Plaster 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 Plaster 40 is a 40 PCF (air-dried density) gypsum plaster/exfoliated vermiculite spray-applied formulation 100% free from asbestos, mineral fiber polystyrene and cellulose.

Pyrok Acoustement Plaster 40 is highly abuse resistant (impact, abrasion) and allows substrates to breathe, and can be readily cleaned by a variety of methods.

2. Uses

Pyrok Acoustement Plaster 40 can be used as a decorative surfacing material, an acoustically attenuating surfacing material or as a combination of these qualities even in conjunction as a fireproofing material. This material is recommended for interior applications where superior abuse resistance is required.

Typically, Pyrok Acoustement Plaster 40 is specified for use in hotel lobbies, atriums, 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 Plaster 40 may also be used on suspended ceilings as a combination acoustical finish and decorative material depending on the structural configuration and building use.

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

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

6. Application Procedures Summary
Pyrok Acoustement Plaster 40 may be applied directly to gypsum wallboard, cement board and other clean, sound substrates.

Contact Pyrok, Inc. for verification of compatibility with substrate and suitability of primer.

Mix in mechanical type mixer with paddle or ribbon type blades. Use 3-5 gallons of clean, potable water per each 35-pound bag of Pyrok Acoustement Plaster 40. Mix 1 to 2 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 Plasterweld/Weld-Crete to the substrate immediately prior to the application of Pyrok Acoustement Plaster 40. Apply a splatter-coat covering 60% to 80% of the substrate surface. Allow splatter coat to cure overnight. Successive coats of Pyrok Acoustement Plaster 40 shall not exceed 1/8 to 1/4 inch thick per application. 2-3 days of drying time will be required after 5/8 inch thickness has been applied and additional thickness is required. Where thickness of the Acoustement Plaster 40 is to exceed 1 1/8 inch, or existing paint is not removed, chicken wire or metal lath must be fastened to the substrate. During application and drying of the Acoustement Plaster 40, temperatures should be maintained between 50 – 95 degrees Fahrenheit. The humidity should be maintained between 45% – 75% for proper application and drying.

Topcoating/Curing
Pyrok Acoustement Plaster 40 may be supplied in several integral colors. 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 Plaster 40 may be removed by brushing or with water. Dry Pyrok Acoustement Plaster 40 may require scraping or chipping to remove.

Pyrok Acoustement Plaster 40 may be vacuum-brush cleaned after set.

Storage and Shelf Life
Store Pyrok Acoustement Plaster 40 off the ground in unopened, original packages and keep dry. Pyrok Acoustement Plaster 40, kept dry, has a one (1) 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, improper maintenance, unforeseeable ambient exposures or other causes beyond anticipated 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.

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 Plaster 40 is processed and shipped from New Eagle, PA. It is composed of the following materials:
– gypsum (Oklahoma)
– perlite (Pennsylvania)
– vermiculite (extracted in South Africa, processed in Pennsylvania)
The light weight of the Acoustement Plaster 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 Plaster 40 materials simplifies handling and reduces installation energy use.

11. Facility Operations Phase
The acoustical properties of Acoustement Plaster 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 Plaster 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 Plaster 40 is durable and can last the life of a building with minimal maintenance. The surface can be vacuumed with a stiff bristle brush. Small smudges can be removed with a soft pencil eraser. If necessary, the Acoustement Plaster 40 can be painted without loss of its sound absorbing properties.

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