What Is International Original Varnish?
International original varnish is a traditional, oil-based yacht varnish renowned for its high gloss finish and long-lasting durability. Developed under the International brand, this varnish is designed specifically for use in marine environments. It brings out the natural beauty of your boat’s woodwork while offering essential protection against harsh weather and UV exposure.
This product is ideal for interior and exterior use above the waterline, including wood trim, handrails, toerails, doors, and decking. Its high clarity and warm golden colour enhance the wood’s grain, giving your vessel a classic, luxurious look.
Why Choose International Original Varnish?
There are many reasons why International’s original varnish is a top choice, some of which include its:
High Gloss and Depth
International original varnish provides a deep, rich gloss that develops beautifully with each coat. Its clarity highlights the natural aesthetics of the wood grain, giving you a premium finish that’s perfect for traditional yachts and modern vessels alike.
UV Protection
One of the biggest challenges boat owners face is sun damage. Our varnish offers effective ultraviolet protection, helping to prevent the wood from fading, drying, or cracking under prolonged exposure to the elements.
Durable and Resilient
With excellent water and weather resistance, International original varnish is formulated to perform in even the most demanding marine conditions. When applied correctly, it offers superior longevity, reducing the need for frequent re-varnishing.
Easy to Apply and Maintain
This varnish flows well and is easy to brush on, making it suitable for both professionals and DIYers. It dries to a smooth, even finish and can be lightly sanded between coats for optimal results. Additionally, if maintenance is required down the line, it can be re-coated with minimal preparation.

- Drying and Sanding – Allow adequate drying time between coats (usually 12-24 hours, depending on conditions) and lightly sand with fine grit paper before applying the next layer.
