Has anyone had any experience of doing this, and could give me any tips please? A year ago I paid a local builder to repoint the gable end (which he did) and to spray it with silicone (which he hasn't, and it seems that he doesn't intend to finish the job). As I can't afford to pay anyone else, I wondered if it was possible to hire the equipment, buy the silicone and do it myself. The stone is ashlar I think (Calderdale, Yorkshire), house is 125 years old.

It was the builder who told me it should be sprayed... The stone seems quite porous and there is a bit of damp coming in on the corner of the gable end beside and above the front door lintel about 1 metre square. The rest of the gable end seems OK, no damp coming through.
Maybe the builder wasn't being honest about what needs to be done. The pointing work he did was good though - it's just that he's left several jobs unfinished (e.g. expanding foam in gaps in external wall around waste pipe rather than cement) and I'm trying to finish them myself. The more I think about it, the less I trust what he told me.

ive got to do this on a wall where i work,its sand stone and very very porus and very old,years ago there was a product called grangers fluid but iirc was rather expensive for 5 ltrs,as we worked in the preservation industry we used to use spirit based dpc fluid which was basically the same thing but im going to be using this,for the job ive got to do.

i would suggest if your going to be doing this your self then obtain a decent hand held sprayer,im luckey ive got a pump to do my job.
and follow the instructions you dont need to go mad and waste it keep the spray close to the wall,and remember if using a ladder be aware it will make things rather slippery

have a good look for any defects letting in water, such as gutters, roof edge, downpipes, windowsills, joints and fix them first.
Like Joe says, a sound wall shouldn't need it, but maybe it is exposed to driving rain and doesn't have enough time to dry out? We don't get that down here so I wouldn't know.
