InSpec Consulting Pty Ltd requested A&I Coatings provide recommendations for the sealing of the Level 4 concrete concourse at the Brisbane Cricket Ground. The existing coating was allowing water through and delaminating, and a cleanable, non-slip coating was needed.
The A&I Coatings specification:
Remove the existing coating/membrane by diamond grinding or shot blasting. Provide a surface that is clean, dry, and profiled to CSP 2 – 3 so that an excellent key can be achieved.
- Apply first coat of Enviroset 2100 Water based epoxy to a DFT of 50 – 75 μm
- Treat all visible cracks using Vitrethane 668 Elastomeric Joint Filler.
- Apply by dual component spray technology Vitrethane 605 Flexible Polyurethane to a dry film thickness of 2mm ± 400 μm.
- After 0.5 – 2 hours, apply one coat of Envirothane 8473 Flexible Two Pack Water Based Polyurethane – Texture to specified colour.
- After overnight dry apply Envirothane 8473 Flexible Two Pack Water Based Polyurethane Non-Skid to colour.
