Megasorber Soundmesh® G8 tape is designed for tough and harsh applications.

Megasorber Soundmesh® G8 tape has an extremely aggressive tack which provides excellent initial holding power. It is a high temperature resistant tape and is capable of operating continuously from -29℃ to +110℃ and intermittently to +138℃.

Megasorber Soundmesh® G8 tape is extremely tough and durable. It is puncture and tear resistant.

It also provides excellent thermal and heat insulation properties.

Megasorber Soundmesh® G8 tape is supplied in widths of 50mm, 75mm and 100mm with standard colours of grey (GR), black (BK) and white (WH). Alternative width tapes or colour options in Dark Grey (DG), Aquatic (Q) and Sandstone (SS) are available by special order, with a minimum order applicable.

A water repellent G8 option is also available.

  4. G8 facing may have a stripy appearance and creases. Hairline creases may appear on the facing when The creases do not affect the acoustic performance.
  5. There are colour variations between batches; whilst we take every care to minimise batch-to-batch variation, in some instances, variation may be unavoidable and will occur.
  6. Dimensional change will occur in the FM foam substrate with change in relative humidity and temperature, this may cause creasing on the Soundmesh® G8 facing. The creases do not affect the acoustic performance.

Installation instructions and care & maintenance guide

These recommendations are for general guidance only. Installation methods must be tested under actual service conditions to determine their suitability for a particular purpose.

Keep acoustic panels flat. Panels must be kept flat during the handling and installation process. Bending or folding sheets may create creases on the Soundmesh® G8 facing. Once formed, these creases are difficult to remove.

Cutting (if required). The panel can be hand-cut by a knife (sharp utility knife or similar), or machine-cut by a bench saw or rotating blade cutter with a toothless blade.

Note: It is recommended to wear gloves during cutting. The Soundmesh® G8 facing edges may irritate or cut the skin.

Clean substrate surface with Megasorber AC5, acetone or similar. The surface must be dry and free of oil, dust, grease, rust and other contaminants.

Install the panels direct-fix using Megasorber A200 or A100 adhesives, with express finish edges or between panels using powder-coated aluminium trim.

Clean dirt and marks on the Soundmesh® G8 facing with Megasorber

M8 Clean block and water. Dry with a microfiber cloth. Remove excessive adhesive on hands, cloth or equipment with Megasorber AC5.

Direct-fix acoustic panels using Megasorber A200 adhesive.

Available in 600ml sausage for caulking gun and 290ml cartridges for cartridge gun.

  1. Apply adhesive on the back of the acoustic panel (NOT on the Soundmesh® G8 facing).
  2. Install the panel immediately after application of the

Application Pattern

Full-size panel (1.2m x 2.4m) adhesive application 

Minimum bead size (glue width) = 10mm to 15mm diameter. Recommended usage: approx. 1.5 to 2 sausages per full-size panel (1.2m x 2.4m), or approx. 2-3 cartridges per full-size panel.

Direct-fix with Megasorber A100

Spray Adhesive

  1. Connect a hose and spray gun to the new canister. Roll the canister backwards and forwards vigorously for 1-2 minutes to ensure the adhesive has not settled or separated during transit.
  2. Spray adhesive onto the back of the acoustic panel (not on the Soundmesh® G8 facing). Spray one coat to seal the porous surface vertically and then a second coat horizontally to achieve maximum adhesive contact.
  3. Spray adhesive on the substrate
  4. Allow adhesive to dry thoroughly. The adhesive should be touch-dry in 3-5 minutes (depending on conditions).
  5. Bond both surfaces together within 10 minutes of the adhesive being touch-dry.
  6. Apply uniform pressure over the surface.

Spray patterns

 

Note: we recommend A100 on a smooth surface, such as refrigeration panels, plasterboards and metal panels. A100 is not suitable for uneven or textured surfaces. For uneven or textured surfaces, such as concrete soffit and brickwork, we recommend A200 adhesive.
