Looks like you got a decent finish on it all 👍 The suppliers of membranes state that if a membrane is being used, it has to be installed to a minimum height of 1.5m if no dpc is being installed. Normally if rising damp is an issue still, it will rise higher as there is no evaporation, as a membrane will stop evaporation.
@troweltalk27192 жыл бұрын
Hi Ross, the ground levels were high around the perimeter of the property the alcoves were suffering with penetrating damp caused from a leaking downpipe , the customer had these issues rectified a few months before we came in & the membrane was used just to stop any residual dampness from bleeding through the new plaster I agree about the evaporation although compared to sand & cement systems the membrane at least offers a pocket of air between the new plaster & the brick which is vented to a degree from the bottom . If the membrane were to be used in a tanking situation then a drainage system would be required to remove moisture build up behind the membrane

Hi Ross. I have seen all of your videos too. I think you have a very good point. I need a system like this, and ultimately there is going to be a trade-off. But it is something I can live with, even if it means problems down the line - the sacrifice is probably worth it.

What are the products used here? I have a chimney breast with (we suspect) salts issues towards the base…there are a few issues up top but they’ll be dealt with soon. Thing is, we’ve been quoted £2,400 to have the entire breast and alcove wall to the left tanked and plasterboarded over…for context, that’s slightly less than the cost to have my entire house sprayed for wood worm and a number of joists replaced! £2,400 seems well out of line to me…particularly as the house is already basically stripped back and ready to go. I feel the removal of existing plasterboard and fitting of the membrane would be within my grasp. I would just need to understand the tools and products that’ld be best to use

Thank you for your kind words. Unfortunately unlike the membrane the liquid membranes that i am familiar with will not allow any residual damp remaining in the base of the wall to escape so like cement render it becomes trapped inside the wall with risk of it being forced out over time

Hi , brilliant video, I’m not a professional plasterer but need to deal with a damp wall in an old cottage property ( no cavity ) it looks pretty straight forward but I don’t feel confident enough yet , one question is do I have to remove damp plaster and render before applying damp proof membrane or can I fix it straight to the wall ? I’m planning on dot and dab boarding the wall afterwards as I’m not really confident about rendering and plastering ! Would appreciate some clear advice and guidance please ? Thanks for help. 2:27 2:28
@nannasfeet3 жыл бұрын
so if it has air pockets behind or a very small cavity , it’s still trapping damp air as the perimeter is sealed and there is no air movement and could possibly cause black mould . Just my thought .
@troweltalk27193 жыл бұрын
The source of damp has to be fixed / eliminated before reinstating any system unless you are tanking a basement for example in which case a drainage system should be installed to carry away moisture build up. Once damp plaster has been stripped the brickwork begins to dry & over a few days you can see it drying. The idea of the membrane is to prevent any residual dampness & salts contained in the base of the wall from reaching the new plaster finish. We do advise to leave the skirting boards/ floor finishes off for a few weeks this allows air to pass under the membrane

The fixings have a sealing cup also the membrane has a raised bed as shown in the vid essentially the membrane sits off the brickwork. It's important to mention that the source of damp is eliminated.

Good video 👍🏼 any idea on how to use this when trying to insulate solid walls? Can this go behind the insulation/batten - won't it squash it? Or use this between battens and put DPC behind battens? Cheers
@troweltalk27192 жыл бұрын
Hi David the most practical way to insulate solid walls & ensure a vapour barrier at the same time is to bond PIR insulated plasterboard to the walls using polyurethane foam adhesive. The foam us moisture impermeable as is the foil back on the boards & so no real need to install a damproof membrane.

Hi Stu, just rewatched the video due to a customer complaint, I've always dot and dabbed (20+ times ish) and never had a problem. Last Friday I did a 1 sqm damp area and used bonding on top of the membrane, plenty of plugs, customer sent photos today, its not drying at all? Any ideas? I'm thinking maybe condensation, it's in a corner of a converted cellar
@troweltalk27193 жыл бұрын
Hi Andrew, it's been less than a week applied depending on the thickness of the bonding coat it will take a while to dry because there's no suction. Your relying on good airflow in the room to carry away any moisture in the plaster & a cellar likely doesn't have that much air movement. I would suggest large fan next to the wall on oscillate mode for a couple of days Hope this helps 👍
