Owatrol Oil – Rust Stabilizer, 300 ml Aerosol

OWATROL® Rust Stabiliser 300ml Spray – Multifunctional Rust Stabiliser and Paint Conditioner for Oil-Based Coatings

OWATROL® OIL is a highly penetrating, air-drying alkyd oil formulated to prevent rust, improve paint adhesion, and provide long-lasting protection against the elements. It is suitable both as a standalone protective coating and as an additive to oil- and alkyd-based paints, varnishes, and stains.

Its unique formula displaces air and moisture in rust, creating a stable, non-flaking surface that can be safely painted over. OWATROL® OIL also saturates dry, porous wood surfaces with oil, preventing paint from peeling and improving the finish on wood.

Product applications

OWATROL® OIL is suitable for a variety of materials and surfaces:

• Metal (rusty or new): steel structures, pipes, railings, equipment, trailers, tanks
• Wood: dry, damaged, porous surfaces, both horizontal and vertical
• Interior and exterior applications

Key features and benefits

• Can be applied directly to rust without the need to clean the metal back to bare metal
• Penetrates deeply into the rust layer, displacing moisture and stopping corrosion
• Forms a stable layer that provides excellent paint adhesion
• Compatible with oil- and alkyd-based coatings, including urethane alkyd paints
• Improves paint flow, extends the open time, and enhances adhesion in challenging conditions
• Fills wood pores with oil, preventing paint from peeling and providing long-lasting adhesion
• Withstands temperatures up to 175°C once fully dry

Application on metal surfaces

• Rusty metal: Apply wet-on-wet until the surface becomes uniformly glossy. This indicates full saturation. After the first application, check for loose rust flakes; these can be carefully removed and the area touched up with OWATROL® OIL.
• New metal: OWATROL® OIL can be used as a primer—one part OWATROL® OIL to three parts alkyd primer, or apply one thin coat undiluted. Once dry, the surface can be painted with paint mixed with OWATROL® OIL.

Application on wood

• Wood in good condition: Prime with a mixture of OWATROL® OIL and paint primer, then apply paint mixed with OWATROL® OIL (usually 5–20% of the paint volume).
• Damaged or porous wood: Apply several coats wet-on-wet without allowing drying time between coats. Once the wood no longer absorbs the product, wipe off any excess oil and allow it to dry. Continue with a standard paint system, adding OWATROL® OIL.

Paint conditioning The product significantly improves the properties of oil-based paints and varnishes:

• Extends the working time with a wet edge
• Prevents paint from sticking, dragging, and setting too quickly
• Improves paint flow, allowing for a professional finish even in challenging conditions

Recommended mixing ratios with paint

• Topcoat paint: 5–20% by volume
• Primers: up to 30%
• Base coat (first coat): up to 50%. These ratios can be adjusted on site depending on the condition and porosity of the surface.
