Prep - Unvarnished Floors: We know preparing a floor for re-coating can be a pain, but it's worth it to get wooden floors looking their best.

Start by sanding the floor. This will give the wood an even finish and help the Ronseal Diamond Hard Varnish to stick. The easiest way to do this is with a floor sander. Dustless floor sanders are readily available which help to prevent weeks of cleaning and can help to provide a better overall varnish finish. Use 120 grit sandpaper and go along the length of the boards. Make sure to wear a good dust mask, especially if not using a dustless sander.

Vacuum sanded areas thoroughly and wipe down with white spirit. If you notice any holes or imperfections use a suitable wood filler to fill them in.

Prep - Varnished floors: This depends what state your floor is in. If the old varnish is just in need of a refresh, give it a light sand with 120 grit sandpaper. Let the dust settle. Then give it a vacuum and wipe it down with white spirit.

If the floor is in poor condition where the existing varnish is flaking off or there are areas that have worn though to the timber, sand the floor back to bare wood using a floor sander. Look at the Prep for Unvarnished Floors section above to see how to do this.

Application of Diamond Hard Floor Varnish. Always do a test area first.

Ensure that the room temperature is above 10℃. Remove all furniture and allow for good ventilation.

Stir the Ronseal Floor Varnish thoroughly before and during application to ensure a consistent finish. Using a good quality brush, start in the corner furthest from the door and work along the length of 2 floor boards at a time.

Apply 3 coats to give the best protection leaving 2 hours between each coat. Before the 3rd coat, give the floor a very light sand by hand along the length of the floorboards with 240 grit sandpaper (don't use a floor sander). Wipe down with a damp cloth. Then put the 3rd coat down.

Scrape off as much varnish as you can from application equipment, then wash in warm, soapy water. Don't put any left over polyurethane varnish down the drain or into watercourses. Local authority waste disposal sites usually have facilities to dispose of unused varnish.

Ronseal Varnish is touch dry after 30 mins. Allow 2 hours between coats.

The freshly varnished floor will be ready for light foot traffic in 2 to 3 hours of the final coat. Wait 24 hours before moving furniture back in to the room taking care not to drag it across or scrape the floor. Full curing time for Ronseal Diamond Hard Varnish is 72 hours.

Easy to use, provides excellent surface and protection by Robert Gibson

I use this for all internal and woodwork. Recently I have fitted timber around all the windows in a house and finished them with this product. Around the sink in the bathroom and kitchen are vulnerable areas due to water being present but this product deals with it easily. I used 3 coats.

Great by Frank Price

Very easy to apply and gives a lovely gloss finish. Dries quickly and wash the brush in water. We have had it down now on an oak floor for several weeks and it is as first applied even though the dog tries its best to scratch it.

Does not do what it says on the tin! by Thomas Stringell

It's a water-based varnish which dries quickly and does not colour the wood. That's the limit of the truth behind Ronseals description about the varnish. It's simply not diamond hard. My floor is absolutely full of scratches within days, despite following the instructions on the tin to the letter and being super careful about the new floor. I'm not impressed. Moreover, the coverage is not nearly what it says on the tin for any normal application - double it. I think if you had a rock hard hardwood floor and used a floor pad for extremely thin layers, then you might just about get the coverage it states on the tin (at a push). I now, reluctantly, have to buy more of this product. I think I would have been better off purchasing a polyx-oil or wax-oil which would be so much more durable. The purchasing experience was excellent though and delivery was great.

A note from us...

Hello Mr Stringell,

I am sorry to hear that you have had an issue with the Varnish. I have looked into drying and curing times for the product.

I can see that you should be able to walk on the floor after 8 hours and that it is recommended that furniture is not returned until at least 24 hours. 72 hour is given as the time that the varnish will be ready for full use. These times could be extended a little at this time of year as it is colder but this should not have a dramatic effect.

If you would like to email me with all the details of your application process and areas of coverage, I will be happy to try and get to the bottom of why this product hasn't worked for you. wood@finishes.direct

Excellent by Grace

Bought because it is said to be non yellowing to the wood, it is what it says on tin and more. Excellent service, quick delivery and great product. Keeps the wood natural looking , still hardens and preserves with little bit of gloss. Love it . Will buy again when needed. Love the most its competitive price .

Did what it said on the tin by Gordon L

Best to coat the length of a couple of timbers at a time, if coating across a few timbers it can leave marks where varnish partially dries before you get back to them. Coat in a warm room.

A note from us...

Thats great advice Gordon, always apply the length of 1 or 2 boards at a time to avoid join marks - Sam

Pleasant and easy to use by Michael Bowles

No odour, goes on easy, very tough. Not as immediately pretty as the solvent-based product it replaces, but does not induce the headaches either!

Applies quickly and fast drying-recommended by Keith Myhill

Fast to apply and dries totally clear and possible to do several coats in one day. It is quite hard wearing but not as hard as a full solvent based varnish-but without the odours and health issues associated with solvent based products. It is so easy to re-coat that when it starts to wear I can slap on a few more coats in a day.

It does exactly what it says on the tin by David Brown

I was using the product on an old pre varnished floor. I did not want to sand back the oak floor as I wanted to retain all the blemishes and discolouration in other words give the floor a fresh look but retain the history. I did a light sand with a small orbital sander to give a key and then a thorough clean with white spirit then applied the recommended three coats, left to cure for 72 hours and what a fantastic result. It is as hard as nails. I only finished the floor about two or three weeks ago so can't comment on the long term durability but so far so good. Service and delivery were excellent . This was the satin version.

Does exactly what is says on the tin!!! by Brian Case

An excellent product I have used before, and will continue to use. I am a woodcrafter, and I use this varnish in circumstances where a wax polish can't be applied. It sets rock hard,is very quick drying (overcoats in 15 - 30 mins depending on temperature), and if you apply 3 coats, then fine sand (320 grit) to remove the nibs before a final coat, it looks fantastic.

This is a low odour, simple to use product that worked very effectively on my sanded floorboards. It dried very quickly too so you can get the three coats on in one day if you get up early! :)

Brilliant finish by Maria Johnstone

This varnish was great, we done 3 rooms with it, it was easy to apply and looks fantastic now it's finished. We have small children too and so far it's standing the test of toys smashing against it. On the down side sanding the floors was a nightmare, anyone considering taking on this headache should look at local companies who will do it for you and probably book a holiday till they have finished. They look amazing but I won't be doing it again, ever.
