How to Fit DraughtEx Floorboard Gap Filler

DraughtEx is perfect to fill your floorboard gaps. Its unique design and the application tool ensure that your floor can be sealed without causing damage to the floorboards. DraughtEx should be applied in between floorboards after they have been treated or painted.

Step 1 - Preparation

Before fitting DraughtEx ensure that the floorboard gaps are clean and free from debris which can be removed using an appropriate tool such as an old credit card or a screwdriver.

When removing debris from between floorboards, care should be taken to avoid any electrical wiring or pipework that may be hidden under the floor.

Step 2 - Starting the Application

Using an old credit card (it is helpful to cut this into a rounded triangular shape which makes it easier to tuck the ends under the skirting board), blunt knife or another appropriate tool push DraughtEx into the floorboard gap next to the skirting board.

The first 1 - 2 inches of the application should be completed using this method to ensure DraughtEx is firmly in place.

Step 3 - Using the Applicator

After you have fitted DraughtEx into the first 1 - 2 inches of the gap and the end is firmly in place, use the applicator to gently push the sealant into the remainder of the gap.

Narrow gaps (or gaps with varying widths of up to 12mm) can still be sealed by simply stretching and compressing the DraughtEx as required.

Step 4 - Cutting to Size

After you have fitted DraughtEx to within 2 inches of the opposing skirting board, the final length of the gap should be measured and the sealant trimmed with about one inch surplus length.

This is done to ensure a good fit during the final stage of installation and to prevent gaps being created at a later stage. DraughtEx can easily be cut to size with household scissors.

Step 5 - Finishing the Application

Once DraughtEx has been trimmed to size, use an old credit card, blunt knife or another appropriate tool to push sealant into the floorboard gap for the last 1-2 inches.

This will ensure a snug fit and create an effective seal between DraughtEx and the skirting board. This method should be applied to each floorboard gap.

Safety Tip - Avoid Injury Risks

The DraughtEx application tool is extremely effective for installing the floorboard sealant due to its slimline fitting wheel.

It is however important to ensure that a safe distance is maintained between the applicator and your leading hand to elliminate the risk of injury. The applicator should be stored in a safe place away from children.

Important: When installing DraughtEx in rooms with open fires or a gas fire, please ensure that a sufficient flow of air to the fire remains. Without sufficient air flow there is a risk of carbon monoxide poisoning. You can increase air flow to the fire without cooling down the room by installing shuttable air inlets in the floor directly next to the fire.
