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.
Prep the caulking gun Cut the seal at the top of the Selleys No More Gaps -Coloured Caulk or Selleys No More Gaps Exterior (if the gap is outside) 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.
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.
Finish Clean up the excess sealant with a damp cloth immediately. Allow it to cure for about 30 minutes before painting.
For a neater finish and easier clean up, you can tape both sides of the gap before applying the product.
