Can you let us know if you have a suitable product that can be applied to OSB sterling guard that would give us class 0 surface spread of flame? Ideally this would be a clear Matt laquer. If you could recommend a product it would be most appreciated. Many thanks, John
For Interior applications we would suggest - Envirograf QVFR Clear Class 1/0 & EN Class B System for Wood (Interior) and for exterior Envirograf ES/VFR Clear Class 1/0 & EN Class B System for Wood (Exterior)
