Sealing Wood Oil

GRAIN GUARD Sealing Wood Oil is specially formulated to nourish, seal and protect exterior timber from the effects of weather, moisture and UV exposure. Blending premium teak oil and Danish oil, it penetrates deep into the wood to enhance the natural grain while helping maintain the appearance of outdoor wooden surfaces throughout the seasons.

Protect Outdoor Wood All Year Round

Outdoor timber is constantly exposed to rain, sunlight and changing temperatures, causing it to fade, dry out and lose its natural character. GRAIN GUARD Sealing Wood Oil helps replenish the wood's natural oils while creating a protective barrier that resists water penetration and everyday dirt. Regular application helps keep timber looking richer, healthier and better protected.

Ideal for garden furniture, decking, fencing, pergolas and other exterior wood, this wood treatment enhances the natural beauty of timber without hiding its grain. The penetrating formula nourishes from within, leaving a durable finish that is easy to maintain and suitable for ongoing care.

Whether you're restoring weathered timber or protecting newly installed wood, Sealing Wood Oil provides long-lasting outdoor protection while helping preserve the natural appearance of your wooden surfaces for years to come.

How to Use

1. Before Application
The surface must be absorbent, clean, dry, free of dust and grease and load-bearing capacity. Remove old paint and waxes and ensure all residue is removed. Heavily weathered surfaces should be sanded before application.

2. Application
Apply the oil with a brush or cloth in a generous and even layer. Highly absorbent surfaces should be treated several times until the surface is saturated. Wipe off excess oil after 1 hour. Then allow to dry for 24 hours.

3. Cleaning & Storage
Brushes should be cleaned with turpentine and then clean, soapy water. Used cloths can self-ignite and should be soaked in water and packed in airtight aluminium foil or airtight plastic bag before discarding. Store out of direct sunlight in a dry, frost-free area.

Coverage: Approximate 10-12m² per litre
