• Euro-Fire EF1 Promatch Topcoat . Approx 10-12 sqm/lt

Upgrade System: The below system process enables the upgrade fire reaction B-s1,d0 classification of ALL non-fire retarded wooden supports classified as D-s2,d0 with a density equal to or higher than 510kg/m3 . The same classification B-s1,d0 is obtained for this process applied on any metallic substrate or any A2-s1,d0 classified substrate (fiber cement, calcium silicate board or gypsum plasterboard type). Adhesion tests must be carried out on the different supports. Apply 1 x 220-240 gr/m2 (150-170 microns WFT) of Euro-Fire EF1 Basecoat Clear, White, Grey or Black.

Euro-Fire EF1: Extended Tests

The below results are based on the current system application weights above for (Maintain & Upgrade) with the face side coated only there is no requirement to coat the rear side of the panels to achieve the rating below. Maintaining (40 mm air-gap) with steel fixing: B-s1,d0. Maintaining (80 mm air-gap / free standing) with steel fixing: B-s1,d0. Maintaining (40 mm air-gap) with wooden fixing (fire treated): B-s1,d0. Upgrading (40 mm air-gap) with steel fixing: B-s2,d0. Upgrading (80 mm air-gap / free standing) with steel fixing: B-s2,d0. *Upgrading (40 mm air-gap) with a wooden fixing non-fire treated: will only achieve a C-s2-d0 so it is advised that either Steel fixings are used, or the wooden fixings are of a Euro Class B spec or coated with 1 coat of the EF1 Euro-Fire basecoat.
