Hacking off Bonding Plaster to Stop Damp Bridging as Plaster too Close to Ground?

Postby VanMorrison21 » Wed Feb 04, 2015 10:06 pm

Hello all,

Damp proof professional tells me that damp proof course in an old terrace house should still be working (well within guarantee date) but reckons problem is the plaster - a bonding mix which he believes is too close to the ground and therefore bridging the damp proof course. Does this sound correct?

His suggested remedy is to kango-hammer hack off the bonding 2 inches up from floor level in first instance, let it dry for 2-4 weeks and see if this works. If not he says I may then have to go about a foot up the wall.

Does this sound reasonable as another damp proof guy said I should have full damp proof done, you know the one with 1 metre of plaster/bonding should be hacked off.

One other question, the bonding as I'm sure you're all aware is a nightmare to get off. After working on away on it with a kango there remains splodge off it utterly welded to the wall. Your average bloke (like me) would say I'm back to the bare brick, but can these splodges of plaster/bonding still possibly cause problems with damp??

All help greatly appreciated, thanks!
