Owatrol Oil - Paint Conditioner and Penetrating Rust Inhibitor for Metal and Wood
A paint conditioner that does two jobs at once:
Owatrol Oil works as both a paint conditioner for oil and alkyd-based paints and as a penetrating rust inhibitor for metal surfaces. Mix it directly into your topcoat, undercoat, or primer - at ratios of 5-20% for topcoats, up to 30% for undercoats, and up to 50% for primers - to improve flow, extend the wet edge, and reduce brush and roller marks without affecting drying times or the appearance of the finished coat.
Penetrates rust and stabilises metal:
Applied neat to rusted surfaces, Owatrol Oil penetrates down to the sound metal, drives out moisture and air, and leaves a bonding film that stops further rusting. It is suitable for use on galvanised steel, aluminium, zinc, and heavily corroded ironwork such as railings, gates, and window frames. Once fully cured, the dry film resists heat up to +175°C.
Improves coverage and adhesion on wood:
Owatrol Oil deeply penetrates aged or porous timber, sealing the surface and improving adhesion of the finish coat. It can prevent peeling on exterior woodwork and helps protect metal fittings set into timber surfaces, such as hinges and fixings on gates or window frames. Coverage is up to 18m² per litre depending on surface porosity.
Unlike paint thinners, it protects your paint:
Thinners reduce paint quality and can alter sheen and drying behaviour. Owatrol Oil replaces thinners as a workability aid while maintaining the inherent quality of the paint. It is colourless with a transparent matt finish, so it does not affect the colour or appearance of the topcoat. For water-based paints, use Floetrol (Easy Flow) instead - Owatrol Oil is formulated exclusively for oil and alkyd-based systems.
