I have a concrete slab as a base in my shed,ive laid a Wickes liquid dpc all over it and it has taken absolutely ages to go off and still feels a little moist to touch.The solution was given three good coats to floor and up on the two coarse brickwork,but the brickwork feels bone dry and the...

sounds a good idea to check the timber studwork for moisture ,the reason for the 60-70% is when mould spores reproduce and get airbourne. The outside as i say has a damp membrane sheeting all around it so any outside moisture should be kept at bay,the studs and ply on the inside feel bone dry...

apparently mould reproduces above 65% rh so thats what i'm aiming for at the moment to reduce that reading ,but if i kill it with the wash then hopefully that should be the last of it.So its best to use a fungicidal killer?Does it have a more effective agent in it?thanks

is this the same case for normal houses as the heating and windows etc can't be on all the time?i have a mould spore of some kind in the shed due to the damp air and i need to keep the rh levels down before i start to bleach and cleanse it all.

ok its constructed from timber studwork,ply on the outside of that with a membrane for water then eml and two coats of render.On the slab there is a course of two bricks all around the perimeter with soul plate on the top,dpc and then the stud walls,ive laid the solution on the floor around...

hi there i'm running a dehumidifier down my shed and am trying to get the humidity levels down to below 60%.Ive put a liquid d.p.c over the concrete floor and after a month or so of being down i'm struggling to see the levels drop.Today is very windy so i have all the windows and door open and...

you might want to put on a damp proof sheeting underneath the eml to stop water penetration getting into the ply

im running a dehumidifier in a room without a ceiling and wanted to ask if the moisture from outside would be drawn in through the felt ,battens and tiling,i have all windows and doors shut .

im running a dehumidifier down at my timber framed shed,i have all windows and vents closed but am concerned that the air maybe being drawn in through the roof as i have no plasterboards on the ceiling .The roof isnt vented but would it be possible for the dehumidifier to draw air in through the...

you can always fix a timber batten to one side of the right angle and fill it out so the batten finish gives you a nice straight line to work to.

point taken i'll seal it all up tomorrow ta for that

thanks for that one mate,ive got a few vents going round the tops of the walls which are only flystop type vents 6 in number but i'm sure they would take in minimal air from outside.Windows and doors are shut. The dehumidifier has given me a near on full bucket of water since putting it in...

ive put a dehumidifier in a damp ish room to dry out the walls so do you think i should have all the windows and vents shut or open as im thinking would moisture come in from outside?

thanks for your answers and yep its a tricky one i'll have to think it through

hi,i'm having trouble with my hot water right now and it fluctuates from luke warm to not as nearly hot as it should be. I have boiler insurance and have called them around and they reckon that the boiler is working fine as the rads are all hot but the fella advised i get a power flush put...

i 'm not sure whats doing it but have read up on all timber and its contents and treatments as thats all i have left in the shed,ive taken down all the plasterboarding and everything is back to the bare timber frame but the on going problem is there .Im in the drylining game and am always...

didn't say they're popping erm you did :) Have read that the adhesive that bonds ply may have a formeldahyde based solution

No i haven't any problems with me breathing or anything else but as strange as it sounds i only get this problem when im in the shed.Its like a sensation in the ears that they're tingling and starting to feel full,and then when i'm out of there it stays with me for a couple of days. Have had...

Ive learnt that ply sheeting can emit formaldahyde gas and maybe this is what i'm exposed to in my shed as i'm getting reaction each time i go there.Some have said to vapour barrier the studwork but would the off gassing get through somehow even if the joints are taped up.?It has screws coming...

cummon then sing up i cant hear ya's :D well the theory on the dimmer is out unfortunately as i've only got normal switches,ive turned the power off to the house and funny enough my ears are still reacting to something so its not the leccy i think
