cupping

try telling a wannabe diy'er that and they think they know better :roll:

 

Yeah the floor is all over the place, we did have a laugh at that. There must only be 10% of each board in contact with the glue. The rest must of been just for show when he was installing it :roll:

 

I don't get it they must have had some knowledge, they knew a surface membrane was needed why bodge it?

 

Take it they just don't give a sh@t.

 

It was an insurance company and the floor was being replaced due to a flood. Looks like they have been told what to do/use but not any experience. I reckon it was a chippy

 

Never known an insurance company to know what is required for a wood fit, I just had a full blown argument today with Insurance company who refuse to pay for surface membrane or rescreed. The customer had 90mm wide 20mm thick antique stain oak down and the builder didn't leave any expansions again :roll:and used self crappy adhesive underlay, plus they've had a flood and moisture problems anyway in the screed, DPM still okay but Rh is 73%. The flood has blown the screed even though the IC recon it's okay :shock: it's really bad.

 

Well the screed is getting dug up now, the rest of the wood is on joists so not sure if it would be better to put down a new screed or put down joist/battens? As there is a staircase in the hall is it still possible to protect the new floor against the old screed under the stairs?

 

HI ALL,
IM NOT SURE IF THIS IS OF ANY HELP,BUT HERE GOES,
I HAD A WOODEN CHOPPING BOARD,1INCH THICK,AND IT WARPED,TO BRING IT BACK TO RIGHT SHAPE BEING FLAT.
GOT A TOWLE,MADE IT AS HOT AS POSSIBLE,WATER FROM KETTLE ,LAY TOWLE OVER CHOPPING BOARD,LAY ON FLAT SURFACE,ADD WEIGHTS LEAVE FOR 2DAYS,BINGO CHOPPING BOARDS WAS FLAT..
MAYBE ITS ABIT OF HELP,ALL THE BEST THO REGARDS..

 

I've got..a really big towel.

 

flooringman
loving your comment lol

 

what width boards are going down now? personally i'd apply a slurry then re-screed, surface membrane then p990 1k the boards down.

 

90,140,160, wide planks going down. I would Like to stick it down too but bit worried about the old screed under kitchen and utility either side of this hall. The sitting room and study are also in this wood but are suspended and haven't been affected by the moisture

 

90mm too thin for naildown and i think 160mm is too wide to nail, so defo a stickdown

 

Try telling that to some1 who has there whole house in these widths nailed down!

 

if it fails doing it that way you're in for a world of hurt :? see if Matt or someone at bwfa will send them some details on correct installation.

 

I dont think it would help mate, when you tell some1 you cant fit 90,160 widths on joists and theres 200 m2 of this stuff fitted through out the house all on joists and its been there over 10 years with out problems, they give you a funny look. Saying that look at the state of the hallway! Not ideal as there may have been issues with fitting these widths on joist in the past for some people. I have told them I would prefer to fit on a new concrete with a decent membrane under it, just have to be sure the damp wont come in from the sides.

 

good luck mate sounds like you'll need it :?

 

Dug up this screed and found all sorts under it. 2 of the old exterior walls and they are soaking wet. A quarter of it was 3 layers of brick straight on earth, half of it was inch thick quarry tiles. Best bit was there was a small plastic sheet covering one of the old exterior bricks and they had screwed straight thru it. Lucky for me the builder says they can't dig down low enough for joists so they are putting a new screed down. Only down side was I hit a water pipe digging it out. Burrr

 

Well at least it'll be done correctly mate
