A keystone, 255 mm wide, 206 mm high and 75 mm deep, with a plain tapered face with a stepped, layered outline. Set at the centre of the head of a window, door or arch, it is the finishing touch that makes a moulded surround look like real stonework, and it sits over the top of a platband or arch frame. The other keystones in the range are Keystone 4.85.001, Keystone 4.85.002, Keystone 4.85.003 and Keystone 4.85.005; pick one to suit the width of your surround.

Like the rest of Gaudi’s facade range it is polyurethane foam: light, moisture resistant and supplied white, ready to paint. Fix it with Multipurpose Adhesive 290ml (G10.U.290), using Joint Adhesive 290ml (G07.S.290) or Joint Adhesive 60ml (G08.S.60) wherever it butts against another piece. Outdoors, finish it with a good exterior masonry paint once it is fixed; the painted finish protects the surface from sun and weather.
