Best Floor Varnish For Wooden Floorboards & Flooring of 2021

With a wide variety to choose from, floor varnish in the UK have boomed in recent years. With floor varnishes being a tricky product to get right without knowing what to look for.

First, you want to choose a varnish that is specifically used for floors because you do not want to be slipping and sliding all over the place.

I think a dark varnish looks best especially on reclaimed floorboards. But for new hardwood flooring then a clear varnish will complement the grain and enhance the look and feel of the room.

Because floor varnish is expensive you do not want to be going back to change the colour especially if you have already purchased and used it.

In this list of the best varnishes for wooden floors, I am going to reveal value for money, quality of varnish and the variety of colours and effects supplied.

Good Floor Varnish Features

A Good floor varnish “MUST” be hard-wearing, oil-based and dries the same colour as advertised on the tin. You can pay a lot of money for a litre tin of floor varnish but that does not mean you are getting the best value for money.

Floor varnish works out about £14 – £16 per 3m2.

• Hard-wearing for high traffic areas
• Oil-based for less moisture retention
• Non-slip oil-based formula
• Deep natural colours, that also dries the same as advertised

The Best Floor Varnishes

I have personally used every floor varnish listed, all the best choices and you will see great results. Remember that preparation is the key to a wooden floor you can be proud of.

Applying Floor Varnish

Applying floor varnish is a simple process, follow the grain and never puddle or apply too much. You must always prepare your wooden floors by sanding, filling and nailing if needed.

Always use a floor filler that is porous so the varnish soaks in and matches to the floor.

• Always sand your floorboards before applying varnish
• Replace any split, rotten or twisted boards
• Use a low-grade sandpaper or belt sander for a smooth finish
• Apply with a soft non-nylon brush
• Brush with the grain for a more natural finish
• Apply two coats to get the right colour and protection

Although a clear varnish would not suit a wooden floor with lots of filler and repairs because you will notice this through the varnish once it dries.

If your floorboards are in good condition or you are planning on using a clear varnish on a hardwood flooring similar to laminated then a clear varnish will look great while protecting your floors for years to come.

Floor Varnish Conclusion

Using a tried and tested floor varnish is always best! I have used each floor varnish in this post and know they look great, easy to apply and lasts the test of time.

There are many brands and various effects when it comes to floor varnishes, be careful before deciding which brand to go with.

I will always recommend the Ronseal Diamond Hard floor varnish because I know it’s the best currently on the market in the UK for both hardwood flooring and reclaimed floorboards.
