Ready for use, lightweight, repair acrylic putty, with zero shrinkage. ULTRALIGHT PUTTY of DUROSTICK is suitable for quick crack repairs and the patching of holes, up to 5cm deep. Use it on walls, ceilings and plastered surfaces made of concrete, wood and gypsum board, both indoors and out. Does not burst nor crack and it is paintable over in less than an hour, without primer. Note: When applied in very small thicknesses to cover hairline cracks, it does not create a visible patch nor does it leave any blemishes, due to the fact that it turns almost transparent when dry.
