Hi, can you recommend any brand of coating for acid and heat resistant to apply on concrete?

*industrial use.

Thank you.

Anyone here familiar with SPAN? National Water Services Commission

Their website is a little confusing.

What license should you get to perform construction at a water treatment plant?

From the website there are class/individual licence but both of them are pointing towards supplying water and maintenance of plant, nothing towards construction.

Do you only need the permit from SPAN only?
