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.
