How to Fill Gaps in Floorboards

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

Filling Floorboard Gaps with DraughtEx

Step 1 - Preparation

Before filling floorboard gaps with DraughtEx you need to ensure that the gaps between the floorboards 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 dirt and debris from between the floorboards, care should be taken to avoid damaging any live electrical wiring or pipework that may be hidden under the floorboards.

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), a blunt knife, a screwdriver 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 before continuing with the application.

Step 3 - Using the Applicator

After you have fitted DraughtEx into the first 1-2 inches of the floorboard gap, make sure the end is firmly in place and then gently stretch the DraughtEx forward along the gap. Using the applicator supplied with your order, carefully push the sealant into the remainder of the gap.

Narrow gaps and gaps with varying widths can still be sealed by simply stretching and compressing the DraughtEx sealant as required.

Step 4 - Cutting to Size

After you have fitted DraughtEx to within 1-2 inches of the opposing skirting board, measure the final length of the floorboard gap and trim the sealant to size leaving approx. 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 a pair of household scissors.

Step 5 - Finishing the Application

Once DraughtEx has been trimmed to size, 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), a blunt knife, a screwdriver 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 and ergonomic design.

It is however important to remember that edge of the fitting wheel can be sharp and to maintain a safe distance between the applicator and your leading hand to eliminate the risk of injury. The applicator shouldn't be used as a toy and should be stored in a safe place away from children.

Important: When installing DraughtEx floor gap fixer 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.
