Our Interior Varnish is formulated for use on all indoor wooden surfaces such as furniture, skirting boards, doors and joinery. It’s water-based which makes it easy and safe to use with minimal clean up – just wash your brush or roller under the tap!

When applied to any wooden surface it will enrich the natural colour and grain of the wood helping to create a lovely smooth finish in either matt, satin or gloss.

The finish dries quickly to form a very tough and durable coating to protect against knocks, scratches and stains. The Varnish is great when applied to either newly or previously stained surfaces as it brings out the depth of colour in the stain finishing any project off nicely.

Coverage & Shelf Life

1 Litre of Wood Varnish will cover up to 12m2

The Extra Tough Interior Wood Varnish should be stored at room temperature, and is guaranteed to work for three years once opened.


Ensure the surface is clean, dry and dust free.

If the wood has been previously varnished, ensure all of the old varnish has been stripped/sanded off first.

New wood should be wiped down with Methylated Spirit if needed.

If you’re staining the wood, ensure the wood is prepared correctly before staining, then you can then simply apply the Varnish directly on to the stain once dry.



Shake the bottle well before use (no thinning required). If you are unsure of the finish, test it on an unseen area first.

Apply evenly using a good quality brush, working in the direction of the grain. The surface will be touch dry within 30 minutes but we recommend waiting an hour before applying the second coat.

If you’re applying the Varnish onto a water-based Wood Stain, apply the first coat gently to ensure you do not disturb the stain.

Apply a second and third coat in the same way as the first. For an extra smooth finish you can sand the Varnish in between coats with a very fine sandpaper. If sanding, be sure to wipe up any dust before applying the next coat.

Always wait one hour before sanding and/or applying the next coat. The surface will be touch dry within 30 minutes but we recommend waiting 24 hours before using the wood.



You can clean varnished wooden surfaces using our Wood Cleaner.
