[mattysupra]

Happy birthday mate.

PS, if you have a reading below 55% rh then the meter dont work .

Yes i said 55% ! + or - 2%

Sounds like your meter is pot on accurate!

 

[JayHS]

below 55% it dont work?
well i am ducked then

i guess

right i am here for now

i will let you know the reading of the moisture asap guys

 

[dazlight]

Happy Birthday kidda

you dont need a £500 one, just one that reads the RH% the one you have will tell you if any moisture in the top 5mm.

Jay you asked for advise mate you have loads here.

The new concrete floor dries at 1mm a day for the first 50mm then longer for thicker screeds.... so say a 6" screed it could take a year. so that will need a dpm

The old concrete floor dont have a dpm so it needs one to have amtico down, now if you take a reading now the floor could read dry as its breathing. But once amtico is laid its not breathing so any raising moisture will be trapped under the amtico and bingo it will come up.

You can take a risk mate and if you do good look but i'm trying to tell you the right way.

This is what can happen

No DPM

This floor has no damp proof membrane, the fitter has screeded over the woodblock with a wood...

 

[mattysupra]

Just for the record and the rest of the installers on here. (keeping you all up to date before it happens)

British standards is soon to change to say -

1mm per day drying for concrete up to 40mm deep.
After 40mm if will need 2 days drying per 1 mm.


The above is a estimate and the actual air Humidity above the floor will make a difference.

EXAMPLE - new concrete 40mm deep should take 40 days to dry. But if RH above is say 85% rh then the concrete will never dry low enough to have a floorcovering.

The above is the reason why our BS says use a hygrometer on EVERY subfloor.

 

[JayHS]

Cheers MattyS

and everyone, yes i am aware of the drying times, and i am waiting for me mate to come n visit n see what he says. but he is doing a job down the south

i can wait..

tick tock, tick tock tickkkkk...........

i am keen to do this correctly, and will not cut corners! i am still keen on doing a dpm first, so avoid problems in the future

i am going to cool it for the week n see what he says.. as i simply need someone to look at the job and the RH reading.

in the meantime i shall be looking at a liquid dpm, and get prices for the fball or adrex as mentioned before, daz you gave a great link to what i need ( cheers dude ) i will look into that later tonight! when the kids are in bed

talk soon and do give up on me just yet! ok guys

 

[lymmranger]

Just spent an amusing 5 minutes catching up on this thread....

Jay are you for real?

Get a Pro in or just throw away your Amtico

if you get a Pro in you will love your floor for many years to come

if you persist in your DIY aproach you will end up ripping it up and throwing it away anyhow, so just do it now and save some cash which you are about to waste if you carry on _ I`m sorry but clearly your questions and attitude tell me that this will all end up badly

...several real Pro fitters have given you advise, they have been ignored or mocked by you

By the way you should research previous posts on karndean and amtico - there are lots of horror stories from folk who have tried shortcuts to save money.

you asked for advice and several people have tried to educate you

why wont you listen

 

[JayHS]

Hi there

i do listen, i do read.. and i am getting advice and help on here!

sorry that you have failed to understand my OP and whilst we all have a little giggle along the way ( at my expense ) and yes i understand what you are saying, this is why you guys on here have pointed out it is a professional job and that is why i am getting a professional in

but i am fully aware of what corners they might like to cut

this is not a posting to find out how i can do it, but like i keep on sayin

i will help, if i can, if i am asked, but i will leave it to the professionals and simply need to find out what i need to buy.. to keep it within budget

but so far, not one professional who have come to look at the job
have pointed out the need for a moisture test!!!!
nor a liquid dpc??


so if you feel i mock you, then oh well.
but in truth i am not going to namby pamby your feelings, nor anyone elses if i ask a stupid question? because this is why i am here.. to ask what i do not know.

but sometimes i too get mocked, but hey... you are the professional


but thanks for the advice

 

[dazlight]

Are you a Coventry fan Jay? We're playing you next week.

 

[JayHS]

Hey Daz
hows it going bud

football? mmm nope not my game.

do we have our own covy fc? i have no idea

 

[JayHS]

hi there guys
this is a serious posting, and yes, i do hear you all say, Fball and screed and so on.. but trying to find a guy that can do that is not that easy. still waiting on my mate to advise

so in the meantime I have been informed that i should or could think about using this?

Forbo Quickfit system

I have been advised as follows, as to the best idea for the condition of my house relating to no DPM, now the problem is that i have had 3 guys ( flooring specialists ) over to look and price up, and the last guy has told me about this Forbo stuff. which sounds good, as I am keen to have some sort of underlay as it were for heat retention, or cold floor avoidance as it were.

any ideas please, or simply let me know what you think. because i am still keen on the idea of living in a tent

1. Amtico vinyl

2. HT or PS amtico adhesive - (depending on hot or cool rooms)

3. Forbo Quickfit system with a dpm - this will give a perfect joint free area, along with a dpm/foil underlay - heat retention

4. Self level cement Cempolay ( cementone ) to get the floor surface 95% - 99% perfect

5. A primer to seal in the dust/old concrete and make a key for the self level cement to bind too


manufacturers spec sheet

Forbo Quickfit is a Looselay
subfloor system comprising a
double layer MDF base and PEFoam
underlay incorporating a
moisture barrier. Forbo Qickfit is
designed for use on subfloors to
receive a resilient floor covering
where normal subfloor
preparation methods cannot be
used.
Forbo Quickfit is suitable for the
levelling of wood or cemetitious
subfloors, and provides a smooth
base with no “grin through” of the
subfloor panels through the floor
covering.
The 4mm thick PE foam underlay
provides additional impact sound
reduction – ( Lw 23 db with 2.5mm
Marmoleum. The integral foil
backing provides an excellent
moisture barrier.
No specialist tools are required for fitting

not sure on the price but i bet it is a lot.

 

[dazlight]

Yes it's good gear mate. Will work using that but it can expand so you might need to leave a gap around the perimeter.

 

[JayHS]

hey there, yeah a 6mm gap is what they say is needed

 

[dazlight]

I put some marmoleum real on it a few weeks ago. It worked well.

 

[JayHS]

hey there Daz

just wondering how hard a surface is of the 3mm and 4mm MDF double layer, will it flex? with a washing mc on it, or a fridge for example?

i think i might not go with this as it has an expansion issue

and as far as i am aware the amtico vinyl has no expansion issues?






ok i am done on the pc for tonight

 

[JayHS]

hi there guys n gals

I had me mate's mate pop over.. and woohoo light at the end of the tunnel.. no I don't mean on deaths door lol but i was starting to feel that way.
no i mean he has found the level and it is not too bad, but I will need about 30 bags of self level



have a look at the item plan below and let me know what you guys think
the house is 1940's and so no DPM is there, but I am going to have a foil backed dpm as well as the liquid dpm that i will use.

1. Amtico vinyl flooring
2. Amtico PH and HT adhesive to stick it down
3. Forbo Quickfit mdf smoothing out flooring ( for a warmer/soft feel )
4. forbo dpm/foil underlay - to replace a liquid DPM + for added heat retention
5. Cementone Cempolay self level screed 15mm thick or less.
6. liquid DPM - something that is suitable and compatible for the cementone - cempolay self level cement "Laybond"??
7. A primer to seal in the dust/old concrete and make a key for the self level cement to bind too



if you think i should use something else at any stage or recommend anything then please do, as I am not sure what is a suitable liquid DPM that will work with the Cempolay CementOne brand, but i understand that this is a Bostik product? is "Laybond" liquid DPM suitable

any advice or assistance would be most welcome

i thank you for reading this and i look forward to a reply

Regards

J

oh and yes it is a 2 stage job, my guy is doing the screeding.. and i am getting a professional in to lay the amtico floor and mdf forbo stuff.

not cheap i know but hey.. a wise man once said ( or typed )
