Belzona Facts

Conventional repairs would have involved either removal and repair off-site or replacement. These methods were considered too expensive and requiring too much downtime. The Belzona repair was carried out in situ, without hotworks and was completed in only one day. The completed application was post-cured using halogen lamps to speed up cure times and improve chemical resistance.
