REPAIR THAT BROKEN MOLDING FROM A WALL OR GATEPOST

For best results use a thick mix and work on an unpainted, clean surface. If the original molding protrudes a few centimetres from the wall, hammer in a few concrete nails every few centimetres and be sure they will not protrude when the molding is complete. The nails help the thick mix bind better. Wet the area to be treated and start to build up the molding until it matches its surroundings. Better to mix a little cement at a time and apply bit by bit. As it is drying mix a little more and so on. How similar it finally is with the original molding depends on your skill and dexterity.
