  • Overview


Equal in performance to Bona Mega, Manns Extra Tough Clear 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 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 curing time of up to 12 hours before using the surface as normal i.e laying rugs and putting furniture back, to ensure full penetration into the wood.

Simplicity of use
Very low odour,quick drying. After leaving my coatings for a week I then used a pure silicone oil and buffed it to get a higher lustre. Very simple and effective. A personal choice.

Product seems to do what's on the tin

Brilliant finish and excellent product
We used this on a hydrated limewash floor. We asked WFD if it was compatible with the limewash and they suggested testing a small area. So we did and then used it on the floor. The varnish has enhanced the finish, allowing the limewash to really come through. It has also left a finish that feels soft underfoot.This is a great product and very easy to use. I'd recommend it to anyone. We also have half a 5l bottle left so it goes really far too.

Great finish and easy to use
Water had got into the varnish of my 10 year old kitchen cabinet doors. Sanded back to bare wood and applied three coats of this with a light sand inbetween. Wood came up a treat and is a good match for the remaining good doors.

Easy to use, satisfactory finish
We were looking for a tough varnish for our family dining table. This seems satisfactory, though a long period of use will be needed before we really know. Despite offering only a very expensive courier service to our area, Wood Finishes Direct happily allowed us to have MyHermes pick up this parcel. It was packaged thoroughly.

Wonderful stuff.
Loved it. Went on easily and quickly in very fine layers. Each layer dried in half an hour (great when you're doing the hallway) and best of all it made the floor look like new. No orangey colour. Just naturally beautiful

Unbelievably easy and non-messy, beautiful finish
We used this product to refinish an African walnut kitchen worktop. After sanding to remove all the old varnish we rubbed in some wood stain where the surface was discoloured. Added the three coats of Mann's Extra Tough as recommended, with light sanding between coats. Two coats the first day, the third the next morning. Enjoyed the result so much we couldn't resist adding a fourth coat! So far, the worktop is standing up to our usual heavy use.

Used over a painted surface with excellent results
I was looking for a product that would protect kitchen cabinets that we painted with a water based paint (Valspar premium satin which was complete rubbish by the way). I applied 2 coats and was amazed by the difference it made to the surface. I know some people have found it difficult to use and, at the beginning I did as well. I think the key is to apply it and then leave well alone, dont feel the need to make another pass with the brush. It can be difficult to see where you have applied, I used a strong uplighter nearby and a small head-torch to help pick up the sheen. When ready for the next coat I lightly sanded with a finishing pad and applied using a small microfibre roller. This left a nice smooth finish and sheen. The coverage was also excellent, actally a bit more than it said I would get. I understand it is not really designed for this purpose but it definitely gets a massive thumbs up from me.

Excellent product and so easy to apply.

Ridiculously delighted with my purchase.
So far ... so very good. This varnish has exceeded all expectations and worked beautifully with my paint spraying machine. After four light coats, the silky-smooth finish to my painted kitchen table has, so far, remained unaffected by hot cups of coffee and careless teenagers. Have ear-marked other projects for treatment after Christmas. Thank you.
