Flexible fillers, like the best-known Selleys No More Gaps, are a builder’s best friend when it comes to sealing the gap between windows, doors, and walls. Unlike solid traditional fillers, they maintain their flexibility and can handle the shock of doors and windows banging shut. Being acrylic based, like paint, they are easily paintable. Acrylic sticks to acrylic. Selleys Phil Ayling says that Selleys has tweaked the formula for several different uses, such as a fastdry formula for painting within an hour, an extra-flexible-and-coloured filler for wooden floors that have to deal with a wide range of moisture loads, a bathroom filler with extra mould protection, and a threein-one version that also works as an adhesive.
Phil personally prefers to leave weatherboard gaps alone but many builders and homeowners like the higher quality finish of sealing those gaps, so Selleys also offers an exterior and weatherboard version with mould resistance and weather resistance, and extra flexibility to cope with natural plank movement.
A painter’s best friend: No More Gaps. For our project wooden house, the extra qualities of the Professional version was a no-brainer — nearly 48 tubes were used on it!
