The ClassicBond fully-adhered system will adhere to wood, wood fibreboard and lightweight concrete. This product may NOT be applied to polystyrene insulation. The ClassicBond Water Based Acrylic Adhesive is intended for bonding to timber surfaces only. Other surfaces must be bonded with ClassicBond 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 or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of this product.
Good roofing practice dictates that ponding water be prevented. The roof surface should have a positive slope of at least 1 in 80 to prevent ponding water conditions. Before starting please consult the “Precautions” section at the beginning of this manual.
If the bonding adhesive is not allowed to properly dry, gas bubbles or blisters may form under the membrane sheet. These bubbles or blisters may subside over time.
Due to solvent flash off, condensation may form on freshly applied adhesive when the ambient temperature is near the dew point. If condensation develops, possible surface contamination may occur and the application of adhesive must be discontinued. Allow the surface to dry and when conditions allow apply a thin refresher coat at a coverage rate that is approximately half of the normal coverage rate when re-adhering a previously coated surface.
Extreme care must be exercised when working on ladders, roofs, or at elevations above ground. If used as an emergency repair to a roofing system, contact the roofing system manufacturer for compatibility and to ensure compliance with terms and limitations of the warranty.
Surface can be slippery when wet, damp, or frost covered.
Do not stretch the product during installation.
Do not expose product to temperatures in excess of 82° C (180°F).
This product is not intended for use where roof top traffic or activity is anticipated without a protective layer installed on its surface.
After the desired flashing height is attained and the membrane has been adhered, grind the chase into the wall with an angle grinder.
Insert the trim into the chase and mechanically fix it using lead sheet clips.
Apply a bead of black silicone along the top of the trim and wall.
