Sadolin Yacht Varnish is a premium clear varnish designed to create a long-lasting, high gloss finish that beautifully enhances the natural colour and grain of exterior wood. This traditional varnish forms a formidable, weather-resistant barrier that protects against peeling, flaking, and water ingress, perfect for doors, windows, conservatories, and other outdoor joinery. Its precise formulation ensures the timber’s natural beauty remains visible while delivering a deep, rich gloss for a timeless finish.

Formulated with advanced UV additives, Sadolin Yacht Varnish offers exceptional protection against sun damage, helping to prevent fading and discolouration even in coastal or marine environments. The flexible, microporous coating expands and contracts with the wood to reduce cracking and maintain a flawless appearance over time. Easy to apply by brush, it provides excellent flow and levelling for a smooth, professional-quality result.

Size & Coverage

Available in a 2.5 L pack size, offering approximately 12–15 m² coverage per litre, per coat, depending on surface texture and porosity. Apply two coats for maximum durability and long-lasting protection.

Preparation

Ensure wood is clean, dry, and free from dust, grease, or previous coatings that may hinder adhesion.
Lightly sand bare or weathered wood to create a smooth, even surface and remove any loose fibres.
For previously varnished surfaces, lightly abrade with fine sandpaper to provide a key for adhesion.
Remove all sanding dust with a dry cloth before applying the varnish.

Application

Stir the varnish thoroughly before and during use to maintain an even consistency.
Apply 2 full coats using a high-quality synthetic brush, working with the grain for best results.
Allow the first coat to dry for 4–6 hours before lightly sanding and applying the second coat.
Additional coats should be added to areas exposed to severe weather or high UV levels for exterior wood.
Maintain a wet edge to avoid lap marks and ensure an even, glossy finish.

Drying & Recoating

Touch dry in 4–6 hours.
Recoat after 16–24 hours, depending on temperature and humidity.

Aftercare & Maintenance

Clean brushes with white spirit immediately after use.
Inspect coated surfaces annually and lightly sand and recoat as necessary to maintain protection.
Regular cleaning with mild soapy water helps prolong the life of the finish.

Important Notes

Do not apply in damp or humid conditions, or if rain is expected before the coating dries.
Avoid application in strong direct sunlight or on hot surfaces to prevent rapid drying and brush marks.
Not suitable for floors or areas subject to continuous water immersion.
