- 4mm filler: fills gaps up to 3mm, comes in a 40m roll
- 8mm filler: fills gaps from 2-7mm, comes in a 40m roll
- 12mm filler: fills gaps from 6-11mm, comes in a 10m roll
the floorboard gap seal is stretchy, and as you apply it to the gaps in your floorboards, you will be stretching it as you seal the gaps. Therefore, a 40m roll will be more than enough to seal gaps totalling 40m in length.
Here's a video showing how to install it:
With no need for adhesive, you can fill gaps in floorboards invisibly, as the colour of the filler mimics the natural shadows between boards. Comes with a free applicator, and will completely seal a range of different size gaps.
You can also use floorboard gap seal to fill gaps elsewhere, such as in sash windows and skirting boards (the gap between floorboards and skirting board can be a source of draughts). To block skirting board draughts, start in one corner of the room and work your way round, cutting the length of seal at the end of each wall. To stop draughts from sash windows, use a blunt knife to push the seal into the gaps between the glass and the frame, and any gaps in the frame itself.How much will I save?A 12' by 12' room has around 25 floorboards, with an average gap area of 3.87' – equivalent to permanently leaving a small window open.Filling floorboard gaps could save a household from £20 to £40 per room, per year and save 110kg of carbon.

Well worth it. I fitted this in the office room before winter and definately noticed the difference. I had so much left over that I installed it in the summer house too which has deck for flooring. Stops all the spiders and odd weed getting through too. Great product, well worth the work to install it. pinakin patel - brighton
Multi-function Bought this primarily to stop drafts in the living room and hall, having otherwise bare floorboards there. Unexpectedly it also seems to have solved the problem of slugs coming up from between the same gaps in the living room at night. I am beyond happy about that! -
Fiddly but worth it I've spent a while hunkered down with my head on the floor fitting this along our draughty skirting boards but the difference between where it's fitted and where it's not is amazing. Old houses with uneven skirting boards and floors will need different sizes for the gaps. Fiddly but worth it. -
Great stuff I second everything everyone else has said. Hours of internet research led to this and it really works. Have only just started to use it so not sure how well it will do over years/decades, but so far, so good. -
Excellent In the past I've spent hours using string, paper and other materials with varying degrees of success. This stuff takes a few minutes to insert into each floorboard using the applicator and is so easy my 6 year old helped me!! Highly recommended. -
Excellent Found the product to be excellent, stretched it to go further and did exactly what I wanted. Great service and quick postage. Will defo recommend you guys. -
It works If the gaps are fairly large it is very easy to fit. Very small gaps can be a bit more fiddly, though not difficult, or technically challenging (I used a paint-stripping knife, rather than the tool that comes with the roll). It's good stuff! -
