For specifiers

Everything you need to name it in a schedule.

A NATSPEC-format worksection, the detail set in CAD and Revit, data sheets, test reports and an editable specification clause. Acosorb does not publish these centrally — we do.

Downloads

The technical library is open — no form. Data sheets for every product, absorption by thickness, the NATSPEC-format worksection, the standard detail set in CAD and Revit, every fire and environmental certificate, and the safety data sheet. Acosorb does not publish these centrally; we do.

Keep the set current

Test reports get superseded. We will tell you when yours has.

The library above is open — take what you need, no form. This is for the other half of the problem: a data sheet you downloaded in March and specified in August may not be the current one. Leave your details and we will email you when a figure or a certificate in that set changes. It also releases the capability statement and the warranty template.

McPherson Painting Pty Ltd (trading as McPherson Coatings, ABN 74 642 311 457) collects your name, email and the optional fields above to send you these documents and to notify you when a test report is superseded. Submissions go to office@mcphersonpainting.com.au and a spreadsheet held by us. We do not sell or share them, and you can ask us for a copy or ask us to delete them at any time. Full detail on the privacy page.

Would your studio rather be walked through it? We run a one-hour session on specifying acoustic finishes — in your office or online, with the sample boxes on the table.

Specification text

Copy the clause below into your specification and edit the bracketed values, or take the full NATSPEC-format worksection from the download set. Send us the ceiling plan and the reverberation target and we will confirm product and thickness before you issue.

ACOUSTIC SPRAY FINISH
Supply and install Acosorb [Acospray DC3] seamless acoustic finish at [35] mm applied thickness to [ceilings / soffits] as shown. Substrate to be clean, dry and airtight, primed with Acoprimer. Colour: [ILA Grey / to architect's selection]. Noise reduction coefficient NRC [0.95] at the specified thickness. Weighted sound absorption coefficient αw [1.00] to ISO 11654, absorption class [A]. Room reverberation to be verified against AS/NZS 2107 by the acoustic consultant. Fire hazard properties: Group 1 to AS 5637.1 (AWTA test 25-004810). Terminate with a sealing profile wherever the finish does not meet a wall or frame. Applied by a licensed Acosorb applicator to the manufacturer's written instructions. Provide sample panel minimum [1 m²] on site for approval prior to commencement. Warranty: 5 years, performance and adhesion.

Detailing

How it meets everything else.

Four standard conditions. A sealing profile is required from 10 mm wherever the finish does not terminate against a wall or frame. On a flat run there is no joint to detail at all — the detailing is the perimeter and the penetrations.

01

Wall connection

1237

Finish runs into the wall substrate. No profile required at this junction.

02

Shadow gap

35

Gap dimension is set by the reveal you draw, not by the material.

03

Service penetration

36

Junction box extended to finished thickness. 3D-printed spacers available for recessed spotlights.

04

Free edge

34

Sealing profile required wherever the finish does not terminate against a wall or frame.

1Substrate — concrete soffit or plasterboard, clean, dry and airtight
4Sealing profile — required from 10 mm
2Acoprimer — adhesion, and prevents seepage into the substrate
5Shadow-gap profile
3Acospray, applied in crossed layers
6Junction box extended to finished thickness
7Wall substrate

Indicative sections, not to scale. Read with Acosorb’s standard detail set; project details to be confirmed. The full detail set is available in CAD and Revit, with a NATSPEC-format worksection — both in the download set above.

Coordination

What the finish needs.

An airtight substrate.

Clean, dry, plasterboard seams closed. Acoprimer for adhesion and to stop seepage into the substrate.

Flatness in the substrate.

The substrate sets the flatness of the finished plane. A sprayed finish follows what is behind it — it does not level it.

Boxes and penetrations extended.

To finished thickness, before we spray. Services and wall returns are sprayed at 10 mm so the contours read.

Above 15 °C.

During application and while it cures.

Plant access.

Room for a scissor lift or mobile scaffold, and power.

Limits

Where it is not the answer.

Impact zones and reachable surfaces.

This is a soft finish. Keep it above reach or protect it. If the brief puts it at shoulder height in a corridor, specify something else.

Sound insulation between spaces.

This is absorption. Transmission is a different problem with a different solution — if the complaint is hearing the next room, a sprayed ceiling will not fix it.

Substrates without plant access.

Spray equipment needs the room to work.

Repairs
Repairable in place, at any scale.

Minor repairs by hand; medium areas with a 38 kg mini machine; major areas refinished with standard plant. No panel to match and no tile to replace.

Cleaning.

Vacuum with a soft brush head, or dry-ice clean. Overspray by airless only — never rolled.

End of life.

Wet the surface and the material lifts off by hand within 24 hours, which is what makes the Cradle to Cradle certification mean something on site.
