Overview

Bona Mix and Fill is specifically designed to be mixed with wood dust to create a natural looking wood filler. Fills cracks, splits and gaps and looks more like the surrounding wood than traditional wood fillers. It can be easily sanded, stained and finished for a more natural-looking repair.

Please Note: This filler can only be used when mixed with wood dust from sanding, ideally from the project at hand. It cannot be used as a stand-alone clear filler.

  • Also available: Bona Mix and Fill Plus for lighter coloured wood types and for gaps up to 3mm wide
  • Alternatively, try Bona Gap Master for filling long, linear gaps between floor boards and skirting boards

Preparation

Surfaces to be repaired must be clean, dry and free from contaminates and surface coatings.

New Wood

  1. New wood should be sanded with a 100-120 grit sandpaper
  2. Collect the sanding dust for mixing with the Bona Mix and Fill
  3. Ensure that areas to be filled are clean and dust free before filling
  4. Indents may need scoring or coarse sanding to provide a key for the filler to adhere to the wood

Old Wood

  1. Old wood should be sanded back to clean, bare wood.
  2. Sanding dust from the first sanding, that may contain varnish, wax or oil should be discarded
  3. Once all top coatings have been removed, re-sand with 100-120 grit sandpaper and retain the sanding dust
  4. Ensure that areas to be filled are clean and dust free before filling
  5. Indents may need scoring or coarse sanding to provide a key for the filler to adhere to the wood

Application

Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer's instructions on the container at all times.

  1. Bona Mix and Fill should be mixed with the retained sanding dust from the job at hand to a putty-like texture suitable for filling the joint or split in the wood
  2. The filler mix can then be easily applied using a Bona Flat Bladed Trowel
  3. Once dried, sand back the repaired area to a flat surface using a 100 to 120 grit abrasive

FAQ

Can Bona Mix and Fill be used to fill gaps between floor boards?

No, structural floorboards always bounce slightly on the joists. This product does not offer enough flexibility to cope with the movement and is more suited to gaps between parquet blocks or minor defects

How much Mix and Fill do I need for 20m² ?

As every surface will be unique, with a variation of depths and widths in gaps/ holes etc there isn't really a one size fits all answer.

Easy to mix and use

I mixed it with the block floor standings. I mixed small amounts as it was my first use of this product and wasn’t sure how far quantities would go. All in all I’m satisfied with the result.

Effective, easy to use.

Filling gaps in newly laid reclaimed parquet and this worked beautifully. You do have to work quickly as it dries fast, so don't use all the liquid in one go! Make sure you have a little left to mix as you go along. Used with fine sawdust from sanding and looks beautiful. Always impressed with Bona products.

Easy to mix and use, fills small gaps (use wood filler for bigger ones), sands down easily, jobs a good un

Very disappointing product

I had a very bad experience with this product. It left grey water stains on my solid oak floor and all the gaps required refilling as the filled areas were full of tiny holes. Also it dries rigid and brittle. I replaced it with Bona Gapmaster which was so much better and is somewhat flexible even when dry. A lot of trouble and not a cheap product. I had an excellent customer service experience with Wood Finishes Direct in resolving the matter though.

I have always mixed dust with PVA to fill cracks, which made a sticky, hard to work with filler. Mix and fill plus gives a smooth filler that goes into cracks really easily.

I was a bit disappointed that the fill was paler than I had expected when mixed with the sander dust. However, I have since tried alternative approaches (sander dust with PVA, with epoxy, and an Osmo wood filler and have decided that the Mix and Fill was the best of this selection.

East to mix up and work with

Great product- easy to mix up into a paste/cream. Filled numerous large gaps 2-3mm between parque bricks and was rock solid the next day.

Mr Peter Harriss
Easy to mix and apply.

It’s very good in small joint gaps, 1 to 2 mm. It didn’t dry as hard as I expected. Didn’t bond in shallow dents.

Didn't come up to expectations

Cracked on drying, which then required a second application.

Perfect, enhances the overall finish of the floor.

Good filler

I mixed it with sawdust from the sanding machine and the results were excellent. Buy with confidence!

R
Rob Harris
Didn’t do the trick

Very runny- took a long time to dry. Requires ultra fine wood dust to build a comparable filler.

Hello Rob, thanks for the feedback, ideally you need to mix this gel with enough sanding dust to get a porridge like consistency. This will then fill holes effectively and dry as expected. For further advice please feel free to call one of the team on 01303 213 838.

Extremely useful for filling gaps on parquet flooring

The Bona Mix and Fill was mixed with sanding dust from a parquet flooring area in our hall. Gaps were filled with the mixed filler and inspected the next morning. Some of the wider gaps had sunk slightly, but these were refilled. The area was sanded again, which left a perfect matched area.

This product is excellent

This product is very good, I used the sawdust from 120 grit paper. I use very little dust to a thickish porridge consistency. Coverage Is great.

The product was easy to apply

Perfect product to give life back to a 1965 floor. Now looks like new. Easy product to use . Very happy with the results. Wood finishes direct were very helpful in giving advice. Nice to be able to speak to staff that are knowledgeable about their products.

Excellent product

Used this to fill some gaps and indents in an engineered oak floor. Used the sawdust from the sanding and mixed it up as instructed. Once filled, sanded and polished it looks great

Unlike the Fiddes version I used on another floor this one remained workable for the time needed to fill the floor.

An excellent idea and a pretty good product

It fills gaps pretty well, even if it does sometimes take a few layers. With a little stain it blends in well with the endgrain too.

It did a good job and is easy to use although you have to get a wriggle on as it does stiffen up quite quickly
