Aquaflex Premium PU is a fluid applied single component elastomeric polyurethane membrane coating that cures to provide a tough, highly elastic seamless waterproof membrane layer. It is used to waterproof building surfaces and extend the life of existing roofing membranes. It is used to repair splits and defects in roofs. Aquaflex Premium PU is self-levelling and provides a highly elastic UV stable surface to protect aged roofing membranes. Aquaflex Premium PU is manufactured using advanced polyurethane technology to provide superior protection. It may be covered with roof gravel, left exposed, or top-coated with silicone for ultimate ponding water and UV resistance.
USE AREAS:
Aquaflex Premium PU is designed as a tough elastomeric membrane coating to seal and repair existing roofs and permanently protect against leaks, and as a self levelling sealer over tar and gravel roof surfaces. It can also be applied to most aged roofing surfaces such as Granulated Modified Bitumen, Single-Ply (EPDM, PVC and TPO) BUR, Metal Roofs, and Spray Foam insulation. It is an excellent alternative to most costly tear-off and re-roofing options. It can also be used as waterproofing for new building on concrete or plywood roof substrates, and primed ice and water shield base-sheet. In exposed applications it is typically coated with a UV Top Coat to provide heat reflective ‘cool roofing’.
GENERAL:
COLOR: Grey
WEATHERABILITY: UV resistant. May be top-coat with a top coat for extra protection.
TOXICITY: Not for use in contact with edible substances or potable water.
ADHESION: Bonds to suitably prepared and primed surfaces such as aged asphalt, aged EPDM, aged cap sheet, composite, concrete, fiberglass, metal, modified bitumen, and most existing coatings on flat or sloped roofs.
ELONGATION: 600% ± 10% TEAR RESISTANCE: ASTM D1624 Die C lbs/inch 32 pli (5.7 kg(f)/cm)
HARDNESS: ASTM D676 50 Shore A
COVERAGE: 8-10 sqm (2 coats) per pail. Coverage rate will decrease on textured surfaces, and more coating will be used on first coat than on additional coats.
SHELF LIFE: 12 months from date of manufacture stored at 21 °C in a cool dry place.
SURFACE PREPARATION: All surfaces shall be sound, fastened as per manufacturers’ directions, clean, dry and free of corrosion, oils and other contamination. Waterblast, wire brush/sandblast roof surfaces as necessary to remove all contaminates and weathered substrate. Prime/seal asphalt, EPDM, concrete and single ply roofing with Aquaflex Floseal water based epoxy primer or Silcor Primer applied as per data sheet- this also acts to resist bleed-through over asphalt surfaces. Varying substrates may require alternate products or treatments. Check adhesion by applying a test area.
DETAIL: Detail requirements will vary depending on specific site and substrate conditions. Typically, a liberal application of Fulaflex PUmastic grade sealant and/or a detail coat of Aquafllex Premium PU Coating at 40 mil thickness, reinforced with polyester fabric embedded into wet base coat and centred over joint should be applied where movement between- or within- surfaces is expected such as at fasteners, joins, laps, cracks, terminations, penetrations and internal/external corner angles or splits etc. Heavier application, additional reinforcements and/or bond breaker tapes should be used where and as required to ensure applied system will accommodate any specific movement within the installation. Blisters in existing roofing systems should be cut out and prepared, followed by a heavy fabric reinforced application of Aquafllex Premium PU to completely seal the area.
APPLICATION:
MIXING: Mix before application to assure uniform color and consistency. Product should not be thinned. A minimum of 2 coats are required at a minimum dry film thickness 1mm.
Apply by brush, roller or spray. Allow the first coat to dry for 6 to 12 hours prior to re-application. Use a 230mm wide 11mm nap roller cover- dip roller directly into pail and apply, or pour product onto flat roof surface and roll out evenly.
Alternatively, apply with airless sprayer sprayed evenly to achieve consistent coverage.
PRECAUTIONS:
DO NOT APPLY THICKER THAN 0.8mm PER COAT.
Do not apply in temperatures below 10°C, above 38°C or if rain is expected within 2 hours. (Best practice is to check forecast and start with clear weather for 3 days)
Do not use this product in a situation that exceeds its physical limits.
Do not walk on Aquaflex Premium PU other than for periodic maintenance; for areas of light foot traffic, create a walking path by applying an additional coat reinforced with polyester Tie-tex cloth, or rubber granules.
DRY TIME: Allow the first coat of Aquaflex Premium PU to dry for 6 to 12 hours. Re-coat as soon as the first coat can be walked on without causing damage, and no more than 48hrs.
NOTE: drying time depends on weather conditions such as temperature, humidity and air movement.
CLEAN UP:
Application tools and equipment can be cleaned with xylene before cure. Once a container of Aquaflex Premium PU is opened, the curing process will start. Use the entire contents of an opened container if possible. Unused product in an open pail will begin to cure from the top down. This can be cut out with a knife and uncured portion can be used.
MAINTENANCE:
Roof structures may settle over time. A periodic inspection of your roof, which includes transition areas, flashing, vents and skylights, is recommended.
Keep drains cleared at all times.
Roofs become slippery when wet- use extreme caution.
Aquaflex Premium PU may be re-coated periodically after thorough cleaning as necessary to achieve adhesion.
CAUTION: For specific Health and Safety information please refer to the Material Safety Data Sheet.
