As my better camera is off being repaired, I can only make poor excuses about the quality of the photography, but here we go anyway.
Pebble dashed churches are quite common in my local area, usually they are Methodist or Salvation Army, and I thought, a copy of one of these would look quite nice amongst all the brick buildings.
My first step was to glue all the windows and the door on, as it would be next to impossible to make a neat job of this after the sand had been applied. Then once they were all dry I covered the church in a layer of PVA and shock it around in a box of sand for a while. Once that was dry it was covered in a diluted PVA mix and extra sand was used to tidy up and bits where the sand hadn't stuck. The current result is a solid layer of sand on the outside of the building.
The next stage will be to tidy up the bits I don't want sand on and then apply a layer of varnish to really seal it all on.
I hope I have given someone ideas from this, until next time.
