Before every pour. The release agent barrier is consumed during each concrete placement and curing cycle. There is no long-lasting treatment that eliminates the need for per-pour application. On multi-pour days, reapply between pours even if the panel surface appears oily.

No. Diesel permanently stains the concrete surface, damages phenolic film overlays, creates environmental contamination, and violates VOC regulations in most jurisdictions. Use a commercial form oil or reactive release agent instead.

Stack on elevated bearers with spacer sticks every 8–10 panels to allow airflow. Store under a covered area with open sides rather than a sealed enclosure. If mould develops, clean with a dilute bleach solution (1:10) and allow panels to dry thoroughly before the next pour.

Reactive (chemically active) release agents produce the cleanest concrete surfaces with minimal staining, bug holes, and colour variation. They are the standard specification for Class 1 architectural off-form concrete.

With diligent maintenance, typical reuse counts are: BB/OES plyform up to 4–8 pours, standard film-faced (120 g/m²) up to 20–30 pours, premium film-faced (220 g/m²) up to 40–50 pours, and HDO up to 20–50+ pours. Neglected panels typically achieve 40–60% of these targets.
