Bona Gap Master Filler

With no experience whatsoever, I have used this product to fill some gaps in our parquet flooring.

I know the received wisdom is to use sawdust and epoxy (or PVA) but I found that gives a much darker colour than the wood. (Not surprising as you're effectively adding water to the wood?) The Bona Gap Master filler is reasonably forgiving in application. I was filling gaps in floorboards and I did mask to avoid getting it on the floorboards - easier than trying to remove later. It's all very time consuming but best approach I've found as a DIY-yer

Easy use, easy to sand, looks great

I found the trick is to mask up each side of the gap and smooth out with a filling knife.

Corking floor board gaps prior to painting. Seems to have worked well. You must insure that any overspreading is wiped away. Best to mask with tape.

Easy to use, very very flexible but because of this can be difficult to clean up excess when Dried so definitely make sure you remove as much excess as possible before it dries. It will make your life a lot easier.

Good quality filler, sands easily and stained well. Well recommended

Very satisfied with your product, easy to apply and looks good, but then I've always had good service from you, thank you.

Renewing product which has cracked and come away from the floorboards it was sealing. Annoying that it did need replacing and was letting in drafts, but it had been in place for 25 years. Removing the old sealant was very easy and installing the new was straightforward. Product arrived very promptly and bog oak is a much more appropriate colour for pine floorboards than other sealants which have a much more restricted range of colours.

Arrived quickly and well packaged. Easy to use and has nicely filled the gaps between the floorboards. As they say when using it, it can be difficult to wipe up the surplus on the wood, I chose not to use masking tape but realise that would have given a better finish. I wiped off the surplus with a damp cloth and best to do this immediately.

Very easy to use especially as it is water based. Just a couple of things to note. I used this to fill between floor boards and there is some shrink back which wasn't an issue for me but could be in some situations. Also, in cold and humid conditions this can take quite a long time to dry. In my case in an unheated renovation project in West coast Scotland in February 48hrs+. It does say this on the tube but it is as well to plan for this if on a similar job. It overcoated with fiddes clear glaze.

Unlike the competition this actually does what it says on the tin (tube actually but you get the drift) flexible easily sand-able not chalky or crumbly would absolutely recommend it may be a few pound more expensive but it is actually better value as does what it should and makes a brilliant finish

We have now purchased this product 3 times. Initially we wondered if it would fill the gaps in our floorboards but it did such a great job that we ordered more to complete the entire room. It really does do what it says it will and it fills the gaps.

I found Duralay underlay easy to fit and seal with waterproof gaffer tape. Not many suppliers supplied it in the wider width and although this is heavier, I found it easier to lay. This was recommended by our flooring supplier and I’m very happy with it

Quality product, hardly any waste due to various plank sizes.

The Bona Gap Filler (Wenge) was the perfect colour/tone for the flooring gaps and this product is easy to use, easy to clean off and dries without much shrinkage. WFD stocked this item at a much cheaper price than many others.

Excellent product will be ordering other products soon

Excellent product so far. It’s easy to apply to the gaps between boards. It’s probably best to use masking tape either side of the boards which I did for a small amount. For the rest of them I wiped the access. away with a damp cloth. With hindsight I think the masking tape method was probably better, certainly it’s cleaner. Only time will tell how good it is. If there was one single improvement, I could make it would be to have a sealable nozzle.

Wood flooring in a bathroom had been badly laid and over time gaps had appeared between all the boards, making the floor unsightly and difficult to clean. Bona Gap Master Filler has transformed the floor which is much improved, even though a perfect colour match was not achievable. Masking tape was used on either side of the gaps for ease of application. A bit time consuming but worthwhile.

Perfect for what I needed to do

Great filler for old pine floor boards, perfect colour match. Highly recommend

This stuff is great doesnt dry too quickly so plenty of time to work. I really like that its water based meaning its easier to work with gives a neater finish and cleanup is easy. Ive previously used a similar product from a diferent brand and the difference is unreal. I will definatly be buying this product for future jobs.

Have used this a few times and keep going back to it to use on our floors. We are renovating room by room and it is easy to use and looks great.

Yep, did what i hoped it would

Goes on well quite pleased with the finish.

Great product gaps in my wooden floor just disappear completely.

If there was an opposite colour for the one I purchased I got it. I just hope it wasn't the whole batch your firm bought.

Looking for a large gap filler,found this company on line,sent for their product which was absolutely what l needed. Easy to use & solved my big gap issue. Would recommend this company.

It helped a novice produce a really good end result on a solid oak floor

Stop draughts and cut down airborne noise transfer. Takes varnish. Looks ok.

This seems much more plyable and easy to work with, I really would not use any other make.

Filled a shrinkage gap in the surface of a dressing table. Worked easily but the colour was not quite right though the gap was successfully filled.

Simple to use. Water soluble so easy to wipe off.
