Where can you use gap filler?

Gap fillers are easy to use and apply with a caulking gun, forcing the filler into the crack. For larger gaps, a spatula or larger pipe can be used to seal up and protect your home. Gap fillers and putties can be applied internally and externally in your property, but you need to ensure the product you select is appropriate for the desired use.

Luckily, Selleys has a wide range of gap fillers perfect for filling in every crack and crevice in your home. Gaps between walls and skirting boards are best filled with a flexible or semi-rigid filler that dries faster like our No More Gaps Interior range. Wood putties are perfect for filling in holes on timber or hiding nails. Water-resistant fillers should be used in bathrooms and kitchens, or areas with high humidity.
