Rust-Oleum Mathys Noxyde Tape

Rust-Oleum Mathys Noxyde Tape is a self-adhesive tape made of a butyl rubber compound protected by a Fleece in Polypropylene used for reinforcement of overlaps of metal cladding roof and wall panels in combination with the Noxyde coating system. 

Features & Benefits

• Easy to apply
• Excellent adhesive properties
• Excellent heat stability
• Excellent adhesion at low temperatures
• High plasticity and formability

Surface preparation

To minimise any sheet movement during this work, the end laps should be fixed via use of rivets at intervals of every other profile, and at a distance of approximately 50-75mm from the cut edge.

All surfaces to be painted are to be thoroughly washed and degreased via high pressure washing at a pressure of 3000 - 3500 psi. (approximately 210 -250 bar). This water jetting operation to incorporate a 5% solution of Rust-Oleum Mathys ND14 Cleaner Degreaser to remove all oils, grease and other soluble surface contaminants. This cleaning solution must not be allowed to dry on the surface; whilst still wet, ensure that the cleaning solution and all resulting loosened contamination is removed via rinsing with copious amounts of fresh clean water.

Any areas which have been noted to exhibit vegetative contamination are to be treated with Rust-Oleum AMW. This should be liberally applied to the affected surface and allowed to act for 24 hours. After this period, the residue of the vegetative contamination is to be removed via dry brushing or water jetting depending upon site conditions and contractor preference.

All rusted areas are to be mechanically de-rusted (with disc sander or mechanical wire brush) to achieve a cleanliness standard of St3 according to ISO 8501 i.e. no brown rusting to remain visible. Where this leaves a “leading edge” of existing coating, this should be feathered to a firm edge.

This cleaning / de-rusting should be conducted to a distance of at least 100 mm (4 inches) either side of the overlap edge.

Priming

All treated de-rusted areas must be primed on the same day. These areas are to be primed with one coat of Rust-Oleum Noxyde (red shade) at an approximate theoretical coverage rate of 400gms per square metre, sufficient to provide a dry film build of 175 microns (= approximately 320 microns wet film). Allow to dry for a minimum period of 24 hours at 20°C.

Tape Application

Apply Noxyde Tape centrally over the joint detail, pressing firmly into the profile of the panel avoiding stretching, tenting or creation of any air pockets. Ensure that the Noxyde Tape is well adhered to both surfaces.

Ensure all applied Noxyde Tape is coated within the same working day with one coat of Rust-Oleum Noxyde (grey shade) at an approximate theoretical coverage rate of 400gms per square metre, sufficient to provide a dry film build of 175 microns (= approximately 320 microns wet film). Allow to dry for a minimum period of 24 hours at 20°C before applying any subsequent coatings.
