For those looking to redo their exterior of their home with diy cement render brickwork, the first thing that should be done is brush off any loose material off the bricks. Once that is complete, spread PVA liberally across all of the brick. Take into account the weather and temperature at the time you are choosing the render. Mix the sand into the mixer first and then add the cement. Once
. the sand and cement are mixed well, add the water/plasticiser/retarder a little at a time. The number of coats needed depends on the thickness of render required. The first coat should be between 3/4 to 1 inch thick. Each coat thereafter should be a little thinner each time. Once the undercoat is dry, coat it all with PVA and trowel it as smooth as possible.
