Belzona Facts
The product had to be surface tolerant as there was no time to get abrasive blasting organized and staged three stories up at short notice. Also, the product had to be fast curing as they needed to get back on line as quickly as possible, and of course had to be abrasion resistant. Just the job that Belzona 1818 was designed for.
