require 30 min protection on two internal vertical steel posts totaling approx 1 sq.m. looking at envirograf but not sure if should get water based or spirit based ? also would 1l be sufficient for this area. thanks Ewen
We would instead suggest Zeroflame Aquasteel WB+
Hollow sections for 30min protection need to be a minimum wall thickness of 4mm.
