Preparation

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.

Equipment Cleaning

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.

Drying Time

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.

Outstanding
This has to be nearly the perfect varnish for floors. I first used this, oh, many years ago, when it first came out, and the floors I used it on are still in perfect condition. The varnish sets like a film of hard-wearing plastic! It is incredibly easy to apply. The only thing you need to take a little care with is that it's not completely clear when it's applied too thick, so if you do have any opaque blobs then brush them until you can't see them and you will be fine.

Very good product.
Have used on 3 floors over the past 5 years. Very good product. You will get excellent results but only if you put the necessary work into preparing the floor.

As ever from Ronseal a superb product!
Having grown up using/seeing Polyurethane varnish, I couldn't believe that a brush water washable but super tough varnish could be made! Yet again, albeit not cheap, Ronseal have delivered an excellent floor covering. I needed 5 coats as apposed to the suggested three. However, I that was my choice. An excellent product, which I hope will endure many years of use! - only time will tell!

Wonderful varnish
This stuff is the biz. It's easy to apply, dries incredibly quickly, and gives a stunning finish. I use 5 coats on stripped wooden floors, with a light sand after coats 3 and 4. This gives an incredible smooth finish. It's not cheap, but it's easily the best there is.

Easy to use. Dries quickly. If you stir too hard, it forms bubbles, so stir it but not too much. Excellent, very hard finish.
Have used this product extensively before. Best price from Wood Finishes Direct, Excellent delivery service.

Great finish. Easy to use.
This is the best floor varnish I have ever used. I recommend at least 3 coats. I used 4 to get a beautiful soft finish. Does not change the colour of the wood.

Excellent - easy to use and a perfect finish
I used it on exterior plywood for a dance floor. Bit cold when I put it down but seems to have done a good job. I have used diamond hard wax before and it is good as well.

Really great quality-brings out the natural colour of the wood well, hard wearing.
I read reviews before choosing varnish for my parquet flooring, decided on this and called wood finishes direct to clarify the was right for the job in hand. Super advice, arrived the next day. Sure enough, thrilled with the results.

Prone, even when applied with the greatest of care, to dry with air bubbles
I have used Diamond hard Satin on all 3 floors of the house we are converting, but thought the gloss may be better for the entrance room. We found despite very careful application it dried with air bubbles which will not sand out.
Our feedback:-
That's interesting feedback thank you. We can't be sure that this is the cause of the problem but it's worth mentioning that bubbles in the varnish, prior to application, is normally the cause of air bubbles in the finish.

It is recommended that varnishes (and most other finishes) are stirred before use but rigorous stirring can cause air bubbles (shaking is even worse) so the advice is to let all the bubbles visibly disappear in the container before applying it.

Excellent as used re instructions on tin.
Great on bare wood. Tried it over Farrow & Ball "Bone" Eggshell paint and the result was alarming! It became yellow and patchy and I ended up with a crackle glaze finish!!
Our feedback:-
Thanks for that feedback Linda, we completely agree. Not recommended for use over most paints!
