The asphalt must be carefully assessed for moisture and/or air entrapment, SUBSTRATE PREPARATION grade and surface finish. Substrate Evaluation Concrete and cementitious substrates New concrete shall be allowed to cure a minimum of 28 days. Concrete shall have a minimum compressive strength of 20.7 MPa (3000 psi) and exhibit a minimum tensile bond strength of 1.4 MPa (200 psi). time. Moist or sheet curing methods should be used, as opposed to the use of curing compounds, which may interfere with the bond of the membrane. Inspect the concrete, includ- ing upstands, and all areas should be hammer tested. Concrete must be suitably finished, preferably by wood float or steel pan. A power float finish is acceptable where the surface is prepared to avoid laitance (a tamped finish is not acceptable). The surface finish must be uniform and free from defects such as laitance, voids or honeycombing. Gypsum and Cement based sheathing Sheathing boards shall be clean, dry and dust free, and shall be properly secured to the structure. Loose, dam- aged, or contaminated boards shall be removed and re- placed. Brick and stone Mortarjoints must be sound and preferably flush poin- ted. Asphalt Asphalt contains volatiles which can cause bleeding and System Data Sheet Sikalastice-624 WP Waterproofing System May 2018, Version 01.01 020915909DOD000015 Bituminous felt Ensure that bituminous felt is firmly adhered or mechan- ically fixed to the substrate. Bituminous felt shall not contain badly degraded areas. Bituminous coatings Bituminous coatings shall not have sticky or mobile sur- faces, volatile mastic coatings, or old coal tar coatings. Metals Metals must be in sound condition. Wooden substrates Plywood and timber based roof decks must be in good condition, firmly adhered and mechanically fixed. All ply- wood should be Identified as conforming to PS 1 for con- struction and industrial plywood by grade, APA (Americ- an Plywood Association) trademark, or equivalent. For maximum smoothness, EXT Type APA, Grade A-C should be used, and the "A" side should be positioned to re- ceive the Sikalastic® resin. Plywood decks to receive res- in directly shall be at least 1/2" thick and attached and supported according to APA guidelines, using only non - rusting screw, spiral or coated nail type fasteners. A good practice would be to recess or counter sink fasten- ers 1/8 to 1/4" and fill with Sikaflex® sealant. Suitable edge support to prevent differential deflection between panels shall be provided. Panel edges shall be tongue and groove or supported on solid blocking. Space panels a � ayiQ BUILDING TRUST 5/9 1/8 to 3/16" at panel ends. Paints and coatings Ensure the existing material is sound and firmly adhered. Existing Sikalastic® System The existing Sikalastic® System shall be soundly adhered to the substrate. Surface Preparation Concrete and cementitious substrates Cementitious or mineral based substrates must be pre- pared mechanically using abrasive blast cleaning orscari- fying equipment to remove cement laitance and to achieve an open textured surface (CSP 3-5 per ICRI guidelines). Loose friable material and weak concrete must be completely removed and surface defects such as blowholes and voids must be fully exposed. The amount of embedment coat required may increase over rough or highly porous surfaces. Repairs to the substrate, fillingofjoints, blowholes/voids and surface levelling must be carried out. Consult Sika for product recommendations based on project require- ments. High spots must be removed by grinding or simil- ar method. Outgassing is a naturally occurring phe- nomenon of concrete that can produce pinholes in li- quid applied materials. The concrete must be carefully assessed for moisture content, air entrapment, and sur- face finish prior to any roofing work. Particular require- ments for priming must also be considered. Installing the primer and membrane either when the concrete tem- perature is falling or stable can reduce outgassing. It is generally beneficial, therefore, to apply the primer and embedment coat in the late afternoon or evening. Gypsum and Cement based sheathing Sheathing boards shall be clean, dry and dust free. Se- cure loose boards if in sound condition. Damaged or con- taminated boards shall be removed and replaced. Brick and stone Power wash and use biodegradeable non-sudsing deter- gent with clean water rinse as required. Asphalt Power wash and use biodegradeable non-sudsing deter- gent with clean water rinse as required. All major cracks should be sealed to allow continuity of the Sikalastic® system. Bituminous felt Power wash and use biodegradeable non-sudsing deter- gent with clean water rinse as required. Treat blisters by star cutting and removing any underlying water. Allow to dry and re -adhere using suitable adhesive. Bituminous coatings Remove any loose or degraded coatings. System 0an Sheet Sikalastic8-624 WP Waterproofing System May 2018, Version 01.01 020915909000000015 Metals Ferrous metals should be thoroughly cleaned by grind- ing or blast cleaning prior to priming (SSPC-SP3 to near - white metal). Non-ferrous metals are prepared by re- moving any deposits of dust and oxidation and abrading to bright metal. Wire brushing can be used for soft met- al such as lead. The surface must be clean and free from grease which, if present, must be removed with a solvent wipe or wash with detergent, rinse and dry. Wooden substrates Timber and timber based roof decks require additional reinforcement such as the installation of plywood, ap- proved insulation or cover board. Small timber protru- sions and suitable decks may be treated directly, provided that the timber is of exterior quality, e.g. ply- wood. Fill joints flush with Sikaflex® sealant. Paints/Coatings Remove any loose or degraded coatings. Ensure the sur- face is clean and free from grease. Sikaplan®/Sarnafil® membranes Clean membranes with Sarna® Cleaner (PVC mem- branes) and Sarnafil" T Clean (TPO membranes) prior to application of primer. Existing Sikalastic® Systems Clean the membrane using a water jet at approximately 140 bar (2000 psi) and biodegradeable non-sudsing de- tergent with clean water rinse. Allow to dry.
