Product details

Decorators Caulk is a flexible, easy-to-apply filler and sealant designed for finishing gaps, joints and cracks around the home. Ideal for decorating and renovation work, it helps create a smooth, neat finish around skirting boards, architraves, window frames, door frames and other interior fittings before painting.

Unlike rigid fillers, decorators caulk retains a degree of flexibility once dry, making it particularly useful for filling small gaps between different materials where slight movement may occur. It can be used to create clean transitions between walls, ceilings, timber mouldings and other surfaces, helping achieve a more professional-looking finish.

Decorators caulk is commonly used to fill gaps around skirting boards and architraves, seal joints around frames and cover small cracks prior to decorating. Once cured, most decorators caulks can be painted over with suitable paints, allowing the repair to blend neatly into the surrounding surface.

Easy to apply using a standard sealant gun, it is a useful addition to any decorating toolkit and is suitable for both professional tradespeople and DIY projects.
