DESCRIPTION
Rust-Oleum® CombiColor® Multi-Surface 7300 coating is a solvent based primer and topcoat in one, based on a modified Alkyd binder, providing good adhesion to many types of substrates. The product is lead- and chromate free.
RECOMMENDED USE
Rust-Oleum CombiColor Multi-Surface 7300 can be applied on many different substrates like wood, metal, mdf, masonry, tiles, most rigid plastics, old concrete and more. We advise to do a small adhesion test prior to the application of the full surface. CombiColor Multi-Surface is intended for brush and roller application. For metal structures in a more aggressive industrial environment we advise CombiColor Original in combination with RustOleum CombiPrimer Anti-Corrosion 3369/3380.

RECOMMENDED WET FILM THICKNESS
105 µm
RECOMMENDED DRY FILM THICKNESS
62 µm
THEORETICAL CONSUMPTION
9 - 10 m²/l at 62 µm dry per coat, depending on colour.
PRACTICAL CONSUMPTION
Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application.
SURFACE PREPARATION
Remove oil, grease and all other surface contaminations by alkaline cleaning in combination with appropriate detergents. Remove rust scale, loose mill scale, loose rust and loose coatings by scraping, wire brushing or sanding. Sand intact coatings to roughen the surface slightly. Test before application the compatibility with the old coating. The surface must be clean and dry during application. New galvanised (bright aluminium-like finish), Zinc and Aluminium (new and old) surfaces have to be primed first with CombiPrimer 3302. Aged galvanized (matt grey appearance, showing white rust) should first be cleaned with an acid cleaner (e.g. Rust-Oleum® SE108) or by mechanical abrasion with for example ScotchBrite. Very porous surfaces should be sealed prior to application of CombiColor® Multi-Surface.
DIRECTIONS FOR USE
To ensure homogeneity, coating materials should be thoroughly stirred prior to use
APPLICATION CONDITIONS
Temperature of air, substrate and coating material between 5° and 35°C and relative humidity below 85%. The substrate temperature must be at least 3°C above dew point
APPLICATION & THINNING: BRUSH
Use natural bristles, long hair brushes. Thinning generally not required
APPLICATION & THINNING: ROLLER
Use short nap, poly-amid 6-12 mm rollers. Roller application may require 2 coats to achieve recommended dry film thickness Thinning generally not required.
APPLICATION & THINNING: AIR-ATOMISED SPRAY
Not recommended.
CLEANING OF EQUIPMENT / SPILLS
Use Rust-Oleum Thinner 160.
