The RKD selection of ClassicBond Kits and membranes offer a fully-adhered system that will adhere to wood, wood fibreboard and lightweight concrete.
DO NOT apply to polystyrene insulation.
Water-Based Acrylic Adhesive is intended for bonding to timber surfaces only. Other surfaces must be bonded with Bonding Adhesive. Roofs over 100m² must also be installed with Bonding Adhesive.
Be sure the roof surface is clean, free of dust, dirt, rust, oil, grease, and
loose material. The roof surface must be dry. This product will not adhere
to wet/damp surfaces. Trapped moisture may vaporize and negatively
affect the performance of your roof.
Good roofing practice dictates that ponding water is prevented. The
roof surface should have a positive slope of at least 1 in 80 to prevent
ponding water conditions.
Unroll the EPDM membrane over the substrate so that the sheet is in the desired position and is wrinkle-free. Water-Based Acrylic Adhesive is intended for bonding to timber surfaces only. Other surfaces must be bonded with
Bonding Adhesive. Roofs over 100m² must also be installed with Bonding Adhesive.
The ClassicBond EPDM membrane needs to be allowed to relax before adhering. The time required for this will vary depending on the weather
Cut the membrane to length if required, and position the sheet to achieve an overhang off the roof of at least 75mm (3”) for both the length and width.
The RUSS (Reinforced Universal Secure Strip) should already be installed wherever the membrane turns up through an angle change. (UPSTAND)
Fold the sheet onto itself so that one-half of the sheet is exposed; take care to avoid wrinkles.
Open and thoroughly stir the WBA Adhesive or Bonding Adhesive. Using a medium nap paint roller apply the adhesive to the substrate, or if using Bonding adhesive, the rear of the membrane as well.
The adhesive must be applied to 100% of the surface in an even coat without globs or puddles. The adhesive can be alternatively applied in a thin coat to the membrane and substrate.
Roll the sheet onto the coated substrate to avoid wrinkles by rolling the middle of the sheet first. Immediately after rolling the sheet into the adhesive, broom the membrane sheet to achieve maximum contact.
NB – DO NOT apply excessive pressure to cause the membrane to wrinkle.
Repeat the application of ClassicBond WBA adhesive for the other half of the ClassicBond EPDM membrane.
NOTE: DO NOT APPLY WBA or BONDING ADHESIVE TO ANY SEAM AREAS.
