Manns Extra Tough Varnish is a clear, water-based varnish that has been specifically manufactured to achieve superior durability on interior wooden surfaces including table tops and furniture.

Very low odour, available in 4 non-yellowing sheen levels. Sheen increases with additional coats. i.e. 3 coats of matt will have a higher sheen level than 2 coats.

Please Note: This product was previously called "Manns Extra Tough Varnish". We recommend Manns Extra Tough Floor Varnish for any hard or softwood flooring.


Equal in performance to Bona Mega, Manns Extra Tough Clear Polyurethane Varnish will enhance the wood grain and its natural colour. This Varnish can also be tinted using our compatible water-based wood dyes. These dyes will keep the varnish looking translucent, making it ideal for matching different woods or simply tinting the surface of the wood you are working on.

This product has anti-bacterial properties making it especially ideal for use on kitchen and bathroom floors and furniture. Can also be used on children's wooden toys.

Note: For flooring - Use Manns Extra Tough Floor Varnish or for commercial grade protection on flooring Manns Extra Tough Pro Floor Varnish.


Prior to applying Manns Extra Tough Clear Varnish, ensure that wooden surfaces are clean, dry, and free from any previous finishes such as waxes, old varnish or wood oils.

It is recommended that new wood is wiped down with a good quality white spirit to remove any grease, dirt and other contaminates from the surface of the wood. The prepared surface will then be ready for coating with Manns Extra Tough Clear Varnish.

Freshly sanded wood should be cleaned thoroughly to remove all traces of sanding dust, dirt and debris.


This product is very easy to apply with a brush or microfibre roller. Can also be sprayed through most electric spray systems as well as compressor based spray systems.

For interior surfaces such as doors, architraves, picture frames, chairs and other low wear areas, 2 coats of varnish will be sufficient. For higher traffic areas such as table tops 1 coat of Manns Classic Primer followed by 2 coats of varnish or alternatively, 3 straight coats of varnish.


Manns Extra Tough Clear Polyurethane Varnish can be cleaned on a day to day basis with Manns Surface Cleaner and a damp cloth or mop. varnished surfaces should never be cleaned with large amounts of water.


Clean off tools using warm water or methylated spirits before dry. If cleaning with warm water, a small amount of detergent can be used if required.


This product stores best when kept at temperatures above 4℃ and below 28℃. As with most water-based products, avoid temperatures below zero or the water content of the product will freeze. Keep container tightly closed and store in a well-ventilated area. If stored in the correct conditions, Mann's Extra Tough Clear Varnish will keep for at least a year


  • In case of contact with eyes rinse immediately with plenty of water and seek medical advice.
  • Wear suitable gloves and eye/face protection.
  • Keep out of reach of children.

Drying Times

A medium coat of extra tough clear varnish will be touch dry within 1-2 hour, and can be recoated after 2 hours. We recommend a minimum curing time of 24 hours before using the surface as normal.

Great product by Steve Hancock

Couldn't be happier by David Howell

Used with Howdens Dordogne oak doors. The doors were initially rubbed over with a 220 grit paper before the first coat and as it's water based, the first coat does raise the grain slightly to give a rough feel to the doors. A very light rub over with 320 grit removes this and a second coat applied. The varnish is incredibly easy to apply and leaves no brush marks and really does highlight the lovely grain of the wood. 1L is enough for 2 doors with 2 coats with a bit left over for about one side of a third. Thoroughly recommended.

Great varnish and easy to apply by Sally Hayes

I read other reviews for this product and am pleased to say the good reviews were right. I used it on oak doors and I wanted a clear varnish that was easy to apply. This went on easily with no drips and has a finish similar to the original doors. I was very pleased with it.

Easy to use and excellent results obtained every time by Paul Cave

This product is easy to use and gives a good result. Working with school aged children it is important to implement issues with regards to Health and Safety and not like other solvent based varnish products the issues are minimal. Well worth trying in the home to obtain the same standard of finish without the odours of solvents.

Fantastic service and top notch product by Janet Clarke

Wonderful product, just what I was looking for. After a visit to a well known hardware superstore and coming out with nothing suitable I turned to the internet and purchased the Matt Extra Tough Interior Varnish - wish I'd looked at your site first. My partner is at the moment varnishing 8 oak doors. This product lets the natural oak shine through, just the effect I was looking for. Delivery service is great - arrived on a Saturday after ordering the day before! It does what it says on the tin (well plastic bottle)! Would recommend your Company to everyone.

Exactly what it says on tin by Julia Vandoorne

Dries incredibly fast which can be good and bad depending on what you're doing. Would have like it to be a bit more glossy though. 3 coats needed minimum however it is ready to be varnished again within 40 minutes so no problem at all!

Great, easy to apply product. Lovely natural finish. Had initial concerns with oak veneer doors, but after advice and re-try have put problem down to faulty batch of doors.

As expected by Nelly Pech

It did leave the floor with a very nice satin sheen. I hope in the long run it will give our floor the protection it promises.

Impressed result was just what was required by Julian Hale

First time using a water based finish usually go for Danish Oil but these doors specified not to use an oil or a wax. Product was applied indoors, dust free temp 18 degrees c on Wickes oak veneer doors with a paint pad for the flat areas and a sash brush for the moulding areas of door. Three coats in total, de-nibbed with 180 grit oxide paper between coats 2 hours between coats. Once applied dont be tempted to touch in areas that dry quicker than others thinking you have missed a bit - wait for the full dying time. Dont to over apply. Dried to a near sprayed finish but with the ease and lack of mess that you get with a paint pad. Happy with the results. If you are thinking of using this product give it a go, follow instruction on bottle and admire your results. Volume calculator was very accurate too

Easy application, great finish and minimal odour by Peter Edwards

I was doubtful that water based varnish would perform as well as traditional solvent based ones I had always used. I was delighted to be proved wrong with this product. The low odour, almost undetectable, was a welcome bonus as was the easy brush clean in detergent and water.
