Remove loose material mechanically or high pressure washing. All surfaces to be coated should be clean and free from dampness. Prefill any static cracks with a proprietary flexible latexacrylic caulk. Consult Sika Technical Service. Industrial Flooring New Drywall Minimum level 4 finish prime with Sika Bonding Primer thinned 10 with water. Note 307 W cannot be applied directly over Sika Bonding Primer. An intermediate coat of Sikagard 203 W is required at 6-8 mils. Painted Surfaces Always ensure that the existing paint is fully adhered and sound. Abrade surface using 100 grit screen or paper. Epoxy paints bitumen paints must be abraded using 100 grit and primed using Sika Bonding Primer followed by a 6-8 mil coat of Sikagard 203 W. All painted surfaces that are abraded require cleaning. CMU Block poured in place concrete Spalled flaking or damaged areas should be repaired using compatible materials.

Sikagard 307 W can be used as a primer when diluted with 25 water. Sikagard 203 W can be used as a block filler on new block. Like surfaces that requires a fill parge coat should use Sikagard EpoCem 75 consult product data sheet. Sikagard 307 W can be applied directly to curedsanded EpoCem 75. Cement screeds plaster asbestos cement lining boards For absorbent substrates Sikagard 307 W may be diluted with 25 of clean water as a primer to kill suction. Dustyfriable substrates seal with Sika Bonding Primer and an immediate coat of Sikagard 205 W to stabilize. Concrete Ensure new concrete is at least 10 days preferably 28 days old with moisture content of 20 WME or less. Prime using Sikagard 307 W diluted 25 with water. Wood Damp Free maximum 18 wood moisture equivalent Apply Sikagard 307 W directly. If wood is prone to raised grain then prime with Sikagard 307 W diluted with 25 water when dry lightly sand and apply Sikagard 307 W to correct film thickness. Metals Remove rust to bright metal. Apply Sikalastic Metal Primer WB or Sikalastic Metal Primer use 2 coats on badly pitted or blast prepared surfaces. Non-ferrous metals can be wired brushed to remove oxidation products prime as above. Degrease or use proprietary metal pretreatment fluid on galvanized if greasy. PlasticsInsulation Most plastics can be coated directly. Use Sika Bonding Primer on selfskinning or slab-stock polyurethanepolystyrene foams. Product is not suitable for open fibrous insulation. Dustyfriable substrates require sealing with Sika Bonding Primer and an immediate coat of Sikagard 205 W to stabilize. Mixing Overcoating Sikagard 307 W Clean off all contamination lightly abrade with 100 grit and apply Sikagard 307 W directly. Pre-mix material using a drill and jiffy blade 300-450 rpm Application Rollers - Product may be applied by short to medium 14 - 38 pile synthetic rollers. Two coats are recommended. Rollers are also used during reinforcement embedment. Brushes - A wide soft nylon or bristle b

rush Two coats are recommended ideally product is applied with second coat at 90 to first. Spray Equipment - Most types of industrial airless spray equipment e.g. GRACO ULTRA are suitable pressure 3000 p.s.i. tip size .11 to .15 and 60 fan angle. Although the product is designed with built in flow the finer tip sizes provide the smoothest finish. Tooling Finishing Note All reinforcements using Flexitape and Reemat GFM must use Sikagard 203 W as the base coat. Cure Mechanism 50F60 R.H. Touch dry 45 mins through cure 1 hour. 68F55 R.H.

Always ensure adequate ventilation. Do not thin or brush out like conventional paints thinning for primer use is permissible. Do not apply the products below a minimum temperature of 40F 4C or a maximum of 90F 32C throughout the application period. Conditions must remain a minimum of 40F 4C and 5F -15C above the dew point. Protect from frost and heat above 90F 32C. Product is not suitable for open fibrous insulation. Sikagard 307 W is normally intended to be used internally however if used externally the natural weathering process of the material may cause slight darkening of the colors and progressive loss of gloss with time. All colors are intermixable. If there is any question as to whether or not the product will adhere to an existing coating or surface a test patch should be applied and evaluated for compatibility and adhesion. Application by roller may result in a slight surface tex

ture when using standard coverage rates. If a smoother finish is required apply 3 thinner coats to achieve desired DFT. Previous coat must be completely dry prior to overcoating. Ensure entire surface is fully dried before proceeding. Crazing may occur when overcoating undried surfaces or when material is applied in a heavy application. Good ventilation is required for Sikagard 307 W to dry properly. Gloss is effected by humidity and temperature. The incorrect assessment and treatment of cracks may lead to a reduced service life and reflective cracking. If additional heating is required do not use gas oil paraffin or other fossil fuel heaters these methods produce large quantities of carbon dioxide and water vapor which may adversely affect the finish. Use only electric powered warm air blower systems. New concrete should be allowed to curehydrate for a minimum of 10 days and preferably 28 days. CAUTION WARNING IRRITANT.
