How to use No More Gaps Exterior

  • Ensure the surface is clean, dry and free from dust, grease, flaking/powdery paint and old or crumbling caulk. IIf porous surfaces are greasy or dirty, Selleys recommends using Sugar Soap. If the surface is non-porous eg glass or metal, firstly clean the surface with Mineral Turpetine and then again with Methylated Spirits. If there is old difficult to remove residue such as old paint, Selleys recommends using a paint stripper.
  • Selleys then recommends sanding the surface back with a sanding block, as the gap filler will adhere more readily to a scratched up surface.
  • Ensure you tape both sides of the gap before applying No More Gaps Exterior. This ensures a neat finish and makes it easier to clean up.
  • Cut the seal at the top of the cartridge and cut the nozzle at a 45° angle, to the size of the gap opening. Fit the nozzle to the top of the cartridge.
  • Insert the No More Gaps Exterior cartridge into the caulking gun.
  • Hold the caulking gun at a 45° angle. Press the nozzle opening against the joint, apply steady pressure to the caulking gun and force the gap filler into the gap and move along the joint in one smooth action.
  • For a smooth finish, smooth with a finger or spatula dipped in water. 
  • Clean up excess with a damp cloth immediately and clean hands and tools with water.
  • Allow No More Gaps Exterior to skin (about 30 minutes) before painting with water-based paints. If oil-based paints are to be used, or if gaps are large, allow sealant to set for about 24 hours and ensure the product is completely cured.
  •  Paint with a good brush will ensure the finish and durability of the paint is increased.
  • If you are filling a rigid crack such as a crack in the wall, Selleys recommends Selleys Spakfilla Colour Smart, as the product goes on pink and dries white when it is ready to be painted.

Not Recommended for:

  • Gaps between tongue and groove boards
  • Gaps between weatherboard overlays
  • Where movement is excessive or areas of frequent water immersion
