I'd like to paint my pebbledashed house , it's cement based render, with spar stones (sharp edges). Please tell me your best/worse experiences? I am considering either a good wash with a stiff brush and water , then a fungicide/primer , then Dulux Weathershield or Sandtex?
Or: jetwash , a diluted coat of Weathershield , then a neat topcoat.
Is a primer essential? ANd rollers,brushes, or a spraygun?
This is a coastal location.
