Features

Typical Properties

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 Chemind Chembond modified mortar.

Use Chemind 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 Chemind 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 Chemind 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.

• 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.
