Walls & ceiling of our Community Building have been lined with wood & we want to varnish them with a fire retardant. Can any competent person apply it? How can we prove that it has been done, (is there a certificate?) and what would your cost be to cover approx 100 square metres of surface?
Thank you for the enquiry, we have contacted you directly for more information. Any competent person can apply these varnishes, after application you can apply for certification.
