Bartoline Exterior Filler Powder is a cement-based formula ideal for repairing exterior cracks, holes and gaps. Easy to mix, simple to use and does not shrink or crack. Has excellent adhesive properties which keep the filler firmly in position and allows a wide range of applications including the setting of non-structural bolts. After setting, the filler can be left as its dried grey colour, or painted over using an oil-based paint or varnish before further paint is applied.Filler Powder 1.5kg
