Where to Buy


Draughts around the house are one of the major reasons why many rooms can feel cold and uncomfortable.

Sealing gaps around common areas of air infiltration, such as window frames and door frames in the living room, can make a difference. Not only does this increase comfort, but it is also a cost-effective way to cut down on energy costs.

No More Gaps vs. Weatherstripping

No More Gaps is good for sealing gaps around the house that don’t have moving parts such as window and door frames. Weatherstripping is used to seal moving components such as doors and operable windows.

What you’ll need:

Selleys Light Speed Caulk gun
Selleys No More Gaps – couloured caulk
• Candle
• Putty knife (optional)
Paint stripper such as Selleys Kwik Strip Smart


1. Check for air leaks
Light a candle around the windows and exterior doors that you think have air leaks. If the flame dances around, there is air flow and you have a leak.


2. Clean area to be sealed
To ensure proper adhesion, remove any old caulk and paint. Make sure the area is free from dust, grease and loose/flaking paint.

3. Prep the caulking gun
Cut the seal at the top of the Selleys No More Gaps -Coloured Caulk cartridge using a knife or secateurs. Cut the nozzle at a 45° angle with an opening that is approximately the size of the hole being filled. Fit the nozzle to the top of the cartridge and insert it into the caulking gun by pushing the base of the canister into the gun.


4. Caulk the leak
Apply steady pressure to the caulking gun trigger to force the gap filler into the area that causes the leak. Move the nozzle along the joint in one smooth action. At the end of each section wipe excess product away with a finger, spoon or spatula dipped in a 50/50 mix of water and detergent.


5. Finish
Clean up the excess sealant with a damp cloth immediately. Allow it to cure for about 30 minutes before painting.


• Use a putty knife or paint stripper such as Selleys Kwik Strip Smart to remove old paint.
• For a good seal, apply the gap filler on the frames on the inside and the outside of the house.
• For gaps greater than 2cm use an expanding foam such as Selleys Space Invader
