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.
I have just clad the walls of a wooden cabin and wanted to bring out the colour of the wood and protect it from drying out to quick, rather than use conventional oil based varnish I used Ronseal diamond floor varnish. This water based varnish was perfect it was easy to apply low odour and dry with in two hours. So I managed to coat all the wall three times in on day for an amazing finish.
Lovely finish which lasts and lasts, easy to apply. Shame the smaller tins no longer available. Good value for money.
Used this on new oak doors, easy to apply and great finish after 3 coats. Low smell and quick drying, plus easy clean up of brushes make the whole experience painless. Good coverage too - 11 doors, 3 coats on both sides = 66 sides!!
Last time I used a Ronseal gloss finish, this time the satin. Both times I have been left with a beautiful finish.
Easy to paint and provides a good finish.
Exactly the finish I was looking for and it was easy to apply
It's easy to apply. The cloudiness of the product does not disappear and the final finish is slightly opaque. I prefer Junckers floor varnishes, but this was half the price and good enough for the small area of floor that I was renovating.
This varnish is 'simply the best' it brushes on very easily and has a brilliant finish. We used it on our wooden floorboards and the finish is amazing. Everyone has commented on our beautiful 'new' floors and it has certainly brought our old floor back to life again... Great product!
Good coverage and easy to use. This created a good looking finish to our new oak floor.
Very easy to apply and looks superb. Cannot comment on durability as it has only been down for a few weeks.
Diamond hard floor varnish. Used it to renew the Parque flooring which had not been done for 10 years. Very happy with result.
Very low odour, easy to apply, dries quickly and as it says on the tin hard finish.
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.
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.
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.
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. firstname.lastname@example.org
Made my oak doors look wonderful! Never mind floors!!
Applied to wood flooring and very satisfied with result. Excellent product.
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 .
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.
Thats great advice Gordon, always apply the length of 1 or 2 boards at a time to avoid join marks - Sam
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!
