- New concrete should be cured for at least 28 days and should have a pull off strength ≥1.5 N/mm². Cement or mineral based substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and to achieve an open textured surface
- Loose friable material and weak concrete must be completely removed and surface defects such as blowholes and voids must be fully exposed.
- Protrusions of more than 3mm must be removed. All intersections of horizontal and vertical surfaces should be profiled with a mortar fillet of 25 x 25 mm.
