Preparation
Surfaces to be waterproofed must be sound,
smooth and free from dust, loose matter, oil, grease or other contaminants. All surface defects shall be repaired using Chembond modified mortar. Use Chemflex PU sealant to fill joints, cracks and form fillets to internal corners or penetrations.
Application
Priming
For internal wet areas, tiled decks, walls, sills or flashings, apply one coat of
Primer "W" or diluted Newflex at 6 -10 m2/litre. For exposed decks, car park slabs, sumps, pits & water features, use Chemind Epocote
F100W water based epoxy at 6 - 10 m2/litre.
Detailing
Detail all internal corners, joints, cracks, outlets & penetrations with a 150mm strip of Fibreglass Reinforcing Mat bedded
between two heavy coats of Newflex and centred over the joint.
Application of Continuous Membrane
Apply Newflex membrane liberally by brush,
squeegee or roller in two or more flow coats to minimum 1.0mm DFT.
Allow to dry fully between coats.
High stress areas
Car park decks must use Chemind
Fibreglass Reinforcing Mat embedded
in two coats of Newflex at 2 m2/litre per coat, fully wetted by thorough rolling.
After full drying, apply a flood coat of Newflex at 2 m2/litre. Roofing, terraces, balconies, decks, box gutters, pools, water features and
wet areas may be similarly treated or coated with Newflex-R100.
Low stress areas
Parapets, hoods, sills, CFC, FC, GRC, precast concrete, bathroom or laundry floors, plant rooms and all non-traffic
areas should be primed and detailed then protected with two full coats of Newflex or Newflex-R100 at 2 m2/litre. Coating application should be made in a
cross direction to previous coat to ensure even coverage.
Surfacing
Newflex membrane is foot trafficable within
8 hours.
Use following systems for specific
situations as listed. Apply surfacing materials only to fully cured Newflex.
Tanking
Cover with Protectoboard, Protectodrain or Rapid Drain, followed by backfill or landscaping.
Rigid Surfaces
0.2 mm PE slip-sheet with concrete
topping.
Paving slabs on Chemind Multi Pads
or bedding.
Chemind Chembond polymer modified render or textures.
Tiles
Ceramic tiles may be laid on a mortar bed or otherwise fixed directly with fully guaranteed Chem-Fix
adhesive
Traffic Areas - Car Parks
Apply Chemind Tuffcote Duratop at
4m2/litre.
Allow 24 hrs drying before exposing to foot traffic or 48 hrs before
allowing vehicle traffic.
Decorative Coatings
Chemind Blockflex high build coating exterior acrylic paints, roll-on textures or sand-filled PP grass.
Insulated - Thermally
Chemind Dow Roofmate closed cell insulation board to provide guaranteed
thermal insulation.
Insulated - Acoustically
Chemind Sound-Shield sound deadening system under tiles etc. to
give the required acoustic value.
Coverage
Total consumption
for the Newflex membrane system is 1.0-1.5 litres/m2.
Packaging
Newflex is packed in 15 litre plastic pails for
the domestic market and in 20 litre metal pails for export.
Shelf Life
Unopened or resealed pails of Newflex has
a shelf life of 2 years, when stored in a dry,
cool place.
Clean-up
Remove uncured Newflex with water.
Chemind GP Solvent may assist with the removal of cured product.
Exercise care when using solvents.
Please review all MSDS before use.
