Some Tips for Renovating Floorboards

Many of our customers use DraughtEx floor gap filler as the finishing touch on a newly renovated wooden floor. Although DraughtEx can also be installed underneath many types of floor coverings such as carpets, most people make use of it to seal the gaps between exposed wooden floorboards.

Polished wooden floorboards provide a beautiful and homely look, however, you need to consider a few points to make sure that the final floor insulation with Draughtex produces the most pleasing results.


While Draughtex is very quick and easy to fit, preparation is still important when it comes to stopping draughts between floorboards. You need to clear out the gaps between floorboards with a blunt knife or similar. Be very careful not to damage any cables or pipes underneath the floorboards. While Draughtex is flexible and will form itself around any remaining debris, the best result is achieved if most of the dirt between floorboards is removed. If you are also sealing the gap between the floorboards and the skirting board, remove any rope that might have been used in the past to seal the gap. Again, remove any dirt out of the gap.

After sanding, make sure you vacuum the floorboard and skirting gaps to remove any larger amounts of dust and dirt. This is obviously important anyway for the varnishing of the boards but will also help when fitting the floor gap seal after varnishing.

Applying DraughtEx

Once your floor is varnished and dried, fill your floorboard gaps with DraughtEx. The filler is available in three thicknesses to cover all gap sizes, although the standard size of Draughtex will be suitable for the vast majority of floorboards. The seal is very flexible and can be stretched to fill thinner gaps. Because of its elasticity, DraughtEx will also accommodate any natural movement of the wooden floor.

Start by pushing the end of the Draughtex seal in a floorboard gap underneath the skirting board using a screwdriver or similar. Use the same screwdriver to position the first two inches of Draughtex between the boards. You then tension the Draughtex very slightly with one hand while using the supplied applicator in your other hand to roll down the Draughtex into the gap. The applicator has a ledge that prevents pushing the floorboard seal too deep. When reaching the other end of the room, just cut off with a bit of a surplus which is pushed underneath the skirting board with the screwdriver. When you are filling in thinner gaps, just increase the tension a little bit more.

The specially formulated colour ‘Shadow’ will appear invisible to the eye and will present clean, even looking floorboards floorboards. You can vacuum the floor without risk of pulling out the Draughtex.

How Much DraughtEx Do I Need?

Two factors influence how much DraughtEx you need to fill your floorboard gaps:

    • Total length of all your floorboard gaps added together
    • The width of your gap

The total length required is quickly worked out. Just multiply the length of one floorboard by the number of floorboards.

Please note that this length is not necessarily equal to the amount of DraughtEx you will actually need. As DraughtEx can be stretched to fit into thinner sections between floorboards when it is applied it can cover a larger area of floor than you would expect it to so you may end with some surplus. We will refund any full rolls you have bought from us.

Happy Birthday DraughtEx!

One year ago DraughtEx was introduced to the UK. The first year has been full of positive surprises and new developments:

About three years ago we started to sell floorboard insulation products. At the beginning of 2010 our MD Harry Dewick-Eisele decided that it was time to develop our own floorboard gap insulation product based on the experience we had made in the previous two years.

Soon all ideas and plans came together and on the 18th of March 2010 we were able to introduce a revolutionary new product to the market: Draughtex

In the next few months we watched with amazement how the floorboard gap sealant was taken up by the market and even through the summer sales were rising.

To find out how customers are getting along using and fitting DraughtEx we  email a customer survey to everybody who places an order with us. Based on the feedback given so far we launched two new versions of DraughtEx floor board gap fillers and redesigned our applicator to make it easier to handle the sealant. The results are warmer homes and happy customers.

We want to even further improve the service we offer. Please tell us any suggestions you might have and we will try our best to introduce your ideas. To help this communication we have joined Facebook to make it even easier to leave feedback and share your experiences with us: visit DraughtEx Floorboard Gap Insulation in Facebook.

Good News About Filling Small Floorboard Gaps!

It is amazing how much cold air can blow even through the smallest gaps and chill the whole house.

Until now we were only able to address gaps with a width of 2-12mm. Customers with smaller gaps found it difficult to apply our current sealant diameters and as a result we received some emails asking for a smaller version of DraughtEx.

In our Customer Care Meeting we reviewed these emails and decided to offer a new product for very small gaps as well as our other two existing diameters.

This week we have finally received samples for the thinner version of DraughtEx. After our quality check was completed we placed an order with our UK manufacturer.

The new Draughtex will be suitable for very small gaps up to 3mm width, ensuring that all floorboards can be treated with this amazing draught excluder regardless of gap width. Like the standard version, it will be supplied in 40m rolls.

If you would like to be informed when the thin version goes live, please send your contact details to the following email address:

Does Draughtex Really Work?

You may have found Draughtex while searching for a solution to stop cold draughts through your floorboard gaps, to get rid of cold feet and to reduce your heating bill. We say Draughtex is the perfect solution to this old problem, but who guarantees you that it really works? Is it as good as stated on our website?

We believe in our product and our sales have exceeded all expectations since Draughtex was launched in March this year.

However, to give you a bit more security we have collated some of the customer feedback we received. Should you still have questions after reading these customer comments, please do not hesitate to contact our customer care team.

Can’t think of anything you could do better. Want to applaud you for the foresight of selling a small sample. We weren’t sure about it and ordered the sample, now see how good it is and will be ordering enough for two bedrooms shortly. Great product!!

17 July 2010

I’m very impressed with the results, as are family and friends. It really gives a lift in defining the floor boards and the effect is much more “finished off” which is a real bonus as I was looking for draft proofing as the first priority without expecting the look to be so good. We put a big rug in front of the fire place but have since taken it up again as the floor looks so good. Great product – reasonably priced given the savings I expect it will make to the heating bills. Thanks very much – I’d be very interested to hear if you have any other products in the pipeline

Very happy with the product for ease of application and results. Would recommend to others.

I used Draughtex to fill gaps in my floorboards and found the finish. far superior to filling the gaps with bits of wood and sanding down. I was amazed how I could stretch it to almost breaking point to fit into the smallest gap. Draughtex gives a dark finish between the gaps and looks great on my 1930’s pine floorboards.I am very very pleased with the finish and will recommend Draughtex to all. When I first tried a sample I found the instructions vague regarding fitting between very small gaps and was about to abandon and try something else, but all other products seemed like they would not stand the test of time.I tried again and found if I really stretched hard enough it would fit into almost any gap. Maybe your website should show a video explaining how to fit into the smallest gap.

Reply: A video that explains the application process to our customers will very soon be launched on our website.
