Additional information

OWATROL® OIL is a versatile, highly penetrating air drying oil that can be used alone or added to paint. Used alone it provides a tough, flexible finish, driving out excess moisture and air and displacing it from rusted metal, so stopping rust. Filling dry porous wood to stop paint peeling. Added to any oil or alkyd based coatings and it will give increased wet edge time, improved flow ability, greater adhesion and unlike damaging thinners, will maintain the inherent quality of the paint without affecting its appearance or drying times.

To condition paint:

1. Prepare surfaces as per instructions on paint can.

2. Apply paint.

3. If paint is sticky, sets-up or drags add OWATROL® OIL until the paint works smoothly, easily and evenly. Allow the brush, roller or spray to be your guide.

As a guide:

Topcoat: As required. Normally 5-20% by volume.

Undercoat: Up to 30% by volume.

Primer: Up to 50% by volume.

For damaged, soft or punky wood use OWATROL® OIL to form a firm foundation for the paint.

Apply OWATROL® OIL neat, 2-4 applications wet on wet, as fast as the wood will absorb it, wipe up any excess and allow to dry overnight (12 hrs). Apply paint as normal.

NOTE: OWATROL® OIL may be added to any coating where the clean up is with white spirit.

To treat rusted surfaces:

1. Ensure surface is dry and free from oil and grease.

2. Remove any loose or flaky material. Do not remove firm rust.

3. Apply OWATROL® OIL wet on wet, as fast as rust will absorb it until an-even sheen is achieved.

4. Leave to dry (24 hrs).

5. Apply finishing coats.

For lightly rusted surfaces use a mixture of 1 part OWATROL® OIL to 2 parts Metal Primer. Do not mix or overcoat OWATROL® OIL with paints containing «hot» solvents ie Xylene or two part coatings.
