Before

Faced with quite an area of very rough stone wall in the basement I've invested in a paint spray gun.  I though it might be a good idea to take a picture before the wall, the equipment, me, and a five mile radius is covered in white paint.

As it happened, once a few airflow hiccups were sorted, it was pretty well behaved and effective.  One wall and some ceiling done as an experiment, now to line up to do all the rest in one go as the overhead of prepping the paint and cleaning up is quite time consuming.
