SURFACE PREPARATION
Preparation of metal air ducts and constructions for flame-retardant paint application should be held in accordance with requirements listed in SNaR 2.03.11-85 “Building constructions protection from corrosion”.
Metal air ducts should be prepared for anti-corrosion undercoat application, in accordance with GOST 9.402-80 “Metal surfaces pre-paint preparation”, level 2. After preparation, anti-corrosion undercoat GF-021(for non-galvanized surfaces) or FL-03K(for galvanized surfaces) is applied. The undercoat thickness should be no less than 50 μm.
Surfaces already coated beforehand should be dedusted and degreased
In case of any undercoat layer defects like distended areas or corrosion stains, surface reconstruction should be performed in accordance with this tutorial.
Applying the “OBEREG-OMV” flame-retardant paint over the undercoat before it fully dries can lead to cracks appearing in fire-resistant coating.
Applying the “OBEREG-OMV” flame-retardant paint over paints or undercoats not recommended in this instruction can lead to adhesion loss and paint peeling off the surface. Thus, it is recommended to paint small test area first, let it dry out and observe results.
