All surfaces shall be free from running water. Refer to the method statement for further details. Adhesive Apply Fosroc Proofex OFB adhesive by scraper or roller at coverage rate to suit substrate, typically approximately 0.2kg/m2. Leave for 5 to 10minutes. Membrane Lightly moisten the Fosroc Proofex OFB membrane on the fleece side to improve the initial bond strength, then roll the membrane into the adhesive before skin formation, and press firmly, press again after 30 minutes if required. A selvedge is provided along both edges of the membrane. The membrane layers are overlapped at th e selvedge to achieve a minimum weld of 50mm. At roll ends, the membrane is butted together and a 100mm wide strip of Fosroc Proofex OGP welded on top of the Fosroc Proofex OFB membrane. For corner detailing use Fosroc Proofex OGP Internal/External corner pieces. For upstand terminations use Fosroc Proofex Metal Strip. For additional details on installation including relevant fixings and washers and a list of Fosroc approved applicators refer to your local Fosroc office. Storage Fosroc Proofex O FB must be stored in a cool, dry store in the original unopened packaging. Store rolls horizontally, not more than one pallet high. Precautions Health and Safety There are no health hazards associated with the use of Fosroc Proofex OFB . For information as sociated with Fosroc Proofex OFB Adhesive please consult the relevant MSDS. Fire Fosroc Proofex O FB is non flammable.

1. Proofex OFB Fosroc Proofex O FB constructive solutions Fleece - backed fully bonded synthetic TPO waterproofing membrane Uses Pro vides a fully bonded waterproof membrane system for building and civil engineering structures and is particularly suited to above ground applications including green roofs ■ Podiums, garden roofs, flat/sloping roofs and green roofs , below - ground waterproofing Advantages ■ Adhesion to most common building materials ■ Environment friendly, no VOC, no plasticisers ■ High resistance to weathering and UV ■ Resistance to root penetration ■ Fast application ■ Welded joints for maximum watertightness ■ Excellent long term performance Description TPO/FPA (Thermoplastic Polyolefin Flexible P olypropylene Alloy) membrane produced by extrusion of granules resulting from the incorporation of ethylene propylene rubber into a polypropylene matrix together with other additives as appropriate to the type of membrane. A synthetic polyester fleece is a ttached to the bottom part of the membrane, leaving a selvedge on both sides for welding. The membrane is manufactured in two differen t colours, it is coloured grey on top and black on the underside. This helps to identify any damages that may occur during application. Standard compliance Independently certified performance, BBA certificate number 15/5242. Specification The waterproofing shall be a 1.2mm/ 1.5mm /2mm thick TPO/FPA membrane fully bonded to the substrate and hot air welded at the seams.
