A fast-drying (60-minute) decorator's caulk is a flexible, water-based acrylic filler and sealant supplied in a standard 380ml cartridge for application via a caulking gun. Specially formulated for fast-turnaround internal prep work, it forms a smooth, crack-resistant seal that accepts overpainting with emulsion, gloss, or oil-based paints within approximately one hour without discolouring the finish. It provides excellent slump resistance and primerless adhesion to plaster, timber, brickwork, skirting boards, architraves, and drywall joints, making it ideal for sealing low-movement interior perimeter gaps prior to painting.
