APPLICATION GUIDELINES

GENERAL DESCRIPTION: Versatile one-component high performance waterproofing product. The product forms a watertight membrane moulded to the contours of the substrate. It can also be used to bridge cracks of up to 2mm width without use of crack filling compounds.

STANDARD APPLICATION PROCEDURE

1. Surface preparation: Surfaces must be clean, sound and free from loose materials Notes: a) Metal surfaces must be primed with RB10 Multi-Prime metal primer. b) Masonry surfaces may be friable – apply Bondseal before continuing to ensure surface is sound before applying RB10 Seal Flex.

2. First Coat: Apply undiluted product to prepared surface. Ensure that the film thickness is at least 1mm thick (2mm is optimum) and that the coating is uniform. Allow drying for at least 4 hours before continuing.

3. Second coat: Apply second coat as described above.

4. Weather coat: Apply Pro-Roof or the selected finishing coating over the waterproofing system.

5. Joints: Embed RB10 BIDIM polyester fabric into the first coat and saturate while still wet with a fresh coating. This increases the film strength over joints. Leave to dry for 6 hours then re-apply RB10 Seal Flex as described above.

OVERALL COVERAGE RATE: Depends on the surface being treated. An approximate guideline is as follows: RB10 Seal Flex: 2 Litres l per m² per application = (2mm film thickness).

SPECIFIC APPLICATION PROCEDURES

Concrete Roofing (New): Inspect condition of screeding: repair if necessary Scrape off loose materials from surface and sweep clean. Carry out Standard Application Procedure

Roofs previously waterproofed with asphalt, malthoid or roofing felt: Remove all loose materials from surface, clean out cracks. Fill the cracks. Apply RB10 Seal Flex for step 2 of Standard Application Procedure. Carry out remaining steps of Standard Application Procedure.

Fibre-cement roofing: Clean down thoroughly using water and wire brush. Treat fungal or algal growths with RB10 Anti-Fungicide cleaner & treatment. Allow to dry then rinse thoroughly, (Refer to the product data sheet). Spot prime metal fasteners (screw/nail heads) with RB10 Multi-Prime metal primer. Fill small cracks (up to 2mm width) by applying RB10 Seal Flex to the crack & allow drying. Fill larger cracks. Allow drying and sand smooth. Carry out Standard Application Procedure over entire roof area.

Galvanized Iron Roofing: Clean down thoroughly using water and wire brush. Sand down red-rusted areas to bare metal and dust off. Then apply RB10 Galv-Prep Etch Cleaner to remove surface contaminants (oils, contamination etc.). Rinse thoroughly. Spot-prime all nail & screw heads with RB10 Multi-Prime metal primer. Seal any holes and open joints by applying RB10 Seal Flex undiluted followed by embedding reinforcing fabric into the wet sealer (open joints and holes greater than 2mm diameter). Allow sealer to dry. Carry out Standard Application Procedure to the patched areas. Apply two coats Pro-Roof roof paint over the roof area to provide a uniform appearance.

New Timber Roofs: Ensure the timber is fully dry before starting. Apply Pink Wood Primer in place of the Priming stage of the Standard Procedure.

Flashings: Carry out the Standard Application Procedure. Apply reinforcing fabric if joints are present.

Roof Extended over Parapet Wall Capping: Carry out the Standard Application Procedure. Ensuring that the coating of RB10 Seal Flex extends over the parapet capping to below the level, which may vary between 100mm to 300mm of the roof on the outside vertical faces and onto the roof surface on the inside.

Parapet Wall Capping: Carry out the Standard Application Procedure. Ensuring that the coating of RB10 Seal Flex must be dressed, which turns down the outside vertical faces of the wall between 100mm to 300mm preventing moisture ingress underneath the wall capping or top of the wall upstand.

Expansion Joints: These are normally sealed using polysulphide or polyurethane sealants. Sometimes a foam insert is also used to reduce the volume of sealant required. RB10 Seal Flex may be applied over sealed expansion joints but should not be used as a joint sealer.

General: Different surfaces require different preparations before applying RB10 Seal Flex. Contact a RB10 Sales Representative or the factory for further Technical Advice. It is recommended that the coating system be inspected after 3 years and a maintenance coat be applied if necessary.

HEALTH & SAFETY: Keep paint away from children. Never smoke, drink or eat while painting. Wear protective overalls, gloves and goggles. If accidental contact with skin should occur, wash immediately with clean water. Harmful if swallowed. Do not induce vomiting. Consult your doctor. Ensure good ventilation during application and drying. Store in a cool, dry place out of the sun.
