Went to price a job today. Property has a lot of damp issues which is all getting treated by a dpc specialist. The owner asked for foilback plasterboard (fair enough) I told him id have to batten the walls out so I can fix the boards he replied why cant you dab them I said because the foil won't adhere to the adhesive and they will just fall off. He then said the dpc specialist knows how to do it ill get him to show you. Anyone know if its possible to that beyond me
 
I'm probably not the best to answer you but this all sounds very strange to me.

What type of property is it? Where in the house does he want D&D to happen?
 
You can dab them on the other way round, but only if you need the room for growing those special tomato plants :rolleyes)

He's off his head mate batten it out like you said :RpS_thumbup:
 
He wants all the ground floor dabbing. Apparently his specialist is showing me next week. Looking forward to it

When would you have to baton out a wall and put up foil backed boards? Surely damp issues can be fixed in better ways? I know some types of property have issues regardless (old terraces maybe) but still think it all sounds odd :RpS_confused:
 
A builder I did some work for bought some foam and stuck them on with that I wanted to batten it out never got a call back!!


I'm using The Plasterers Forum Mobile App

By the sounds of it it's all hacked off floor to ceiling I guess & if he wants foil backed boards he's gonna have to fix to battens.

Yeah not at all disputing you. Just asking a genuine question I don't know the answer to. Is it common for people to do this as a damp solution? Or only in certain situations? Because the damp is still there isn't it? Just behind the board
 
dab them on back to front like you said and while growing tomatoes you can strutt round in some pygama bottoms pretending to be Bruce Lee in Enter the Dragon !?
 
Its a really old terrace house and all the plaster is falling off. The owner give me a specification sheet on what the dpc specialist wants so it covers his guarantee which it says boards must comply to bs 1230 which are foilback boards.

I know your not Jess :RpS_biggrin:
It depends if it's on the spec.
But foil backed boards are usually used to form a vapour barrier to stop moisture getting through the board to cold spaces behind.

You would do this when you have not got a F*****g clue or you owned a foilback board factory and your wife was taking you to the cleaners in a messy divorce. This won't do nothing appart from hide what's behind it for bit longer than a normal board but not much. Then again if they fitted a vent it would clear the problem but maybe that's what he is doing aswell the crafty grrrrrrr
 
You can only dab boards on to tanking and even then the spec should be insulated plasterboards with mechanical fixings. but you defo cant dab duplex boards

I thought you were supposed to put a tight scratch coat over the tanking slurry and dab to that. Otherwise beads of condensation can form on the slurry as its impervious to moisture and potentially pop the dabs.
 
i always put a waterproof render onto the brickwork and tanking slurry on top of that when the render is still green. allow the slurrry to cure for about 7 days then dab on top

Mechanical fixings through the tanking???

It's a bit of a **** because all your skirting boards then need to be stuck on. When i've dabbed over a damp proof system, i've not put fixings any lower than 1200mm from floor.

All the damp firms I have worked for would all use any kind of fixing at any level through a waterproof barrier as a get out of the warranty.

The warranty states any fixing through the water proofing will result in water ingress and negate the warranty. Blah blah blah
