Painter's Caulk is an easy to use, low odour, acrylic sealant ideal for internal or external use. It is ideal for sealing joints between skirting, architrave, stairs and walls, around windows and window sills and where limited movement occurs prior to decorating. Easy to apply it gives a smooth finish which doesn't require sanding before painting. Painter's Caulk can be painted with water based (emulsion) paints after as little as 1 hour.
