COVERAGE:
Varies according to the substrate condition. Approximately 2m2 per litre of product, per coat. A minimum of two coats is recommended.
STANDARDS:
Conforms to NZS 3604:1999. Complies with NZ Building Code Clause E2/AS1.
PREPARATION:
The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent the adhesive bonding.
New concrete should be left with a wood float finish and sufficiently aged as per manufacturer recommendations.
All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement that may cause cracking.
The substrate should ideally be dry or damp (at most) but not wet.

As a Primer:
Mix one part water to one part product with a mixing paddle.
APPLICATION:
