There are no solvents in any can foam that will have any effect on any plastic used in construction I'm aware of - it's even (chemically) safe with PVC wiring (unlike EPS). 2 Link to comment Share on other sites More sharing options...
Onoff Posted March 26, 2018 Author Share Posted March 26, 2018 F***! F***! F***! Changing the foam gun cannister over just now and I went to screw on the gun cleaner.....Lucky I had glasses on as I got a full blast of acetone in both eyes! Head under sink asap and the right is pretty much back to normal. Left one slightly more irritated! 1 Link to comment Share on other sites More sharing options...
SteamyTea Posted March 26, 2018 Share Posted March 26, 2018 Oh, looks almost as red as my Mother's eye after her cataract operation last week. Man up, I used to work with polyester resin a lot, it can splash a fair bit. We used to wash it out of our eyes with acetone. I had my cataracts done at age 47!! 1 Link to comment Share on other sites More sharing options...

I'd only had one beer (the last Estrella). More miffed I might not be able to have another if I had to go to A&E tbh. Going to self medicate with a new Lidl lager whilst the foam goes off. 1 Link to comment Share on other sites More sharing options...

Was going to go 3:1as per the mix instructions, water/SBR. I won't be trowelling it, more barrow/shovel/tamp to falls. I wasn't saying use PVA, rather waterproofer & admix rather than SBR, then you will get a workable waterproof mix Link to comment Share on other sites More sharing options...

Onoff Posted March 27, 2018 Author Share Posted March 27, 2018 DPM in and pipes clipped to the mesh. Edges foamed. I was a bit worried where the mesh had rubbed against the pipe but found 1" offcuts of mt fitted the bill perfectly. Also used a couple of bits to protect from the wall drain brackets. Slapped a bit of the perimeter expansion strip against the wall drain secured with spray adhesive. The new wet room slab bit will only expand against this or the blue foam encapsulating the waste. BUT...in time honoured @Onoff fashion I STILL can't find the fibres to add to the mix! Bought for the original slab pour they've just never reappeared. I'll be buying more! As for cement..I've got lots...one bag of Blue Circle use by date Oct 2017 and half a dozen bags of Redland circa Aug 2016. All still in their plastic bags and feeling soft enough.....do I REALLY have to buy new? Link to comment Share on other sites More sharing options...

It comes out like tough plastic and is very workable. I think the term is "polymerize". t Link to comment Share on other sites More sharing options...
Onoff Posted March 28, 2018 Author Share Posted March 28, 2018 So...going for the wet room corner slab this weekend as I am I'm looking for some validation for the above 1 : 1.5 : 1.5 cement/sand/10mm aggregate mix I'm going with as I'm aware it's a bit "out there"! Nearest I could find was the 1:2:2 mix here: It is in effect a small pre-cast area I'm thinking. Recommended for "garden furniture" I'm thinking those concrete benches you see are as tough as old boots. Or would the 1 : 2.5 : 3.5 in the above table be better? Dithering over the mix here!

Construction Channel Posted March 28, 2018 Share Posted March 28, 2018 You really are a worrier. Screed is usually about 3-1 so just stick with what you originally planned. Im concreting Saturday as well. Iv even booked the pump so there’s no turning back now. :-/ also got to be out for lunch by 2:30 so hopefully I can get an early start on it. 2 1 Link to comment Share on other sites More sharing options...

You're never going to drop that weight by CHEATING! Doh! If I hadn't have taken the pi$$ I could have lined the boot with a tarp and scrounged a couple of barrows worth!

I'm sure I will have a few barrows spare if you wanted it, Its only gen 3 so might not be up to your standards, as for cheating, iv got 9.9 m3 to lay, by myself, in one hit before lunch, there will be a lot of swearing if the lorry isn't here before 8 1 Link to comment Share on other sites More sharing options...

Onoff Posted March 28, 2018 Author Share Posted March 28, 2018 Yep, that'll work! Some surplus 40x40x1 angle cut, bent and sprayed. Should allow me to get the falls spot on as per CAD: This side needs a tweak: 1 Link to comment Share on other sites More sharing options...
Onoff Posted March 30, 2018 Author Share Posted March 30, 2018 All ready for filling up with my exotic pea shingle mix. Can't think of anything else that'll delay it! Fall according to Geberit was 1-2% which equated to 13-26mm. I was going to go for the 1% but with no glass screens for the mo and no UFH working I figured get rid of the water a bit quicker. Aimed therefore for slap bang in the middle 18mm (1.5%). According to the laser level on the steel former it's 450mm at the high ends and 432mm where the steel is flat under the yellow cover. I'd say luck more than judgement but it is tbh judgement! All vacuumed and vacuumed again. I just need it stop raining so I can get on with it!

Onoff Posted March 31, 2018 Author Share Posted March 31, 2018 I think I might carry on with figuring the studwork pockets before I concrete. Otherwise I won't be able to tread on that area for a week and it'll slow things up... Link to comment Share on other sites More sharing options...

Onoff Posted March 31, 2018 Author Share Posted March 31, 2018 Modding the stud work for the pocket. I could have just stuck the pocket between the studs but I want it to line up with a specific tile layout. That white area of thick old render is hollow sounding and pretty loose tbh. It's an old blocked up doorway there I think, filled in with thinner blocks than the rest of the wall. Someone even made an attempt to render over the cream painted wall! Bodge after bodge.
