Self Levelling Screed
I'd appreciate advice.
I'm refurbishing my conservatory. The floor is concrete but is not universally flat because of an inexpertly filled in channel for pipes, wiring etc. I'd like to lay either carpet tile or textured vinyl tiles. Does anyone here have experience on the successfulness (or otherwise) of self leveling screeds? TIA JonH |

I have heard what Bruce says to be true of some of the gunk sold. If the floor is dry (ie there is a functioning DPM in there) then the one true answer by my own experience is: F Ball Stopgap 300 HD. You would need P131 (probably) to prime the existing floor. Try to do a single pour to get at least 3-5mm (5mm flows better than 3mm, but I have done a 21m2 floor to 3mm to within +/- 1mm or so in a single pour with help). You can buy it from he http://yorkflooringsupplies.co.uk/st...131-p-295.html http://yorkflooringsupplies.co.uk/st...-hd-p-291.html IME you *must* have this: http://yorkflooringsupplies.co.uk/co...0cm-p-409.html (or the smaller version). Removing air bubbles sounds fancy, but the other effect is it helps the mobility of the fluid to achieve self levelling. F Ball Ltd seems to be the business, although I have used the Wickes Master stuff (which think is made by them). Do check the sell by dates on the Wickes stuff though, I've had a bad experience with an out of date batch. As Bruce says, it needs a little work with a float and works in thin layers, but its easy enough to do. The approach I used (from this forum) was: http://photos.dionic.net/v/public/bu...or/2009-10-03- img_0023.jpg.html Sorry, not a clear picture. It's a T bar of 2x1" wood with 3 round head screws set 3mm out from the edge of the bar. This allows you to push the material around to about the right level quickly and from a standing position. You also need a big bucket and a power mixer (drill type OK for 2 bags, plasters mixer will do 3 bag mix). Mix in the middle of the pour area if pouring a lot.

I will happily defer to it as you have had more recent experience of screeding large areas. The DIY sheds' self levelling screeds are still useful for smaller areas, even if they don't do exactly what it says on the tin. Anyway, thanks for your detailed advice, which I have filed for future reference. |

That's not strictly true ATM. I would never have got there or even bothered when I had the seasonal flu, but the swine flu I had wouldn't stop me getting there in 30 seconds. I can get stuff done in about a 1 hour window of oppertunity, 30 mins after taking the next does of lemsip. after that it goes downhill. ATM I can barely make 5 hours before feeling so crap I make another lemsip, so running on a slight overdose but I don't care... It's all relative. £50? Feck that. But I can move for drugs and for the bog (I am going to have to be clinically dead before I start ****ing the bed!). Swine flu... Well, I did read the NHS web site. Yes, I have the right number of factors to make it possible, but it's a bit stupid because those factors apply to any flu and even a really bad cold. So I rang the GP like they said I should. I'm not sure how they know it's swine flu without a blood test? Could be anything. Anyway, Dave's bat trick didn't work, but Olbas oil helped a bit.

wibbled on Monday 01 March 2010 13:37 So I rang the GP like they said I should. I'm not sure how they know it's swine flu without a blood test? Could be anything. GP rang back. "Almost 0% chance of swine flu round here" he said - "fair enough, just doing what the NHS website said to do" I replied. "Get some Solpadeine and some neurofen. Solpadeine 2 off, every 4 hours for the day and neurofen at night". Boy that solpadeine is good gear. I'm still ill but I don't care about it Finally I can treat flu as it should be treated, a good excuse to stay in bed and watch TV. Pharmacist said "Ah, man flu then". I wanted to say, "but at least I only become completely useless and sociopathic once a decade, not monthly", but as they are the only pharmacist for miles.... -- Tim Watts Managers, politicians and environmentalists: Nature's carbon buffer. |
