I'm pretty sure I've got penetrating damp (happens only when there's
heavy rain) and my DIY book says I should use water-repellent paint all
over the exterior wall to cure the problem.

I've looked on the 'net and found this:

http://www.dampstop-dryzone.co.uk/ds...?idProduct=237

i.e. £80/25litres or £3/litre

However, I visited B & Q and found Thomson's water proof paint at £8/5
litre or £2.50/litre.

Is any of this stuff any good?

How long does it last?

Is there any special recommendation?

I've had excellent results with this

but the wall in question was already painted. If it's bare brick, I'd
think carefully before painting anything on to it.

yes quite. Penetrating damp patches suggests a non-cavity wall,
which suggests a historic property. Rain repellant paints really
arent the best solution. Ask people with the subject knowledge:
