It wasnt primed at all before the first coat of 1200. And when I say pinholes all over the place I mean thousands of them over the 25m2 floor. Anyway, the contractor assured me the F77 would cover them. BUT, it did not. It looked like every pinhole in the 1200 became even worse after the...

I have just had the same problem with FBall Stopgap 1200...pinholes all over the place, and on 2 sections of kitchen concrete floor laid 25 and 50 years ago. Most importantly, the Stopgap1200 is the first layer of a liquid DPM sandwich,...ie 1200 then F77 then 1200 again, to address rising...

I suppose it is regrettable that we, the customers, must treat safety-critical trades (eg electrical and gas) with the same scepticism as other potential "rogue tradesmen" who over-charge for strictly unnecessary, over-inflated jobs. I have not heard from the Checkatrade electrician who said he...

I have researched this more. I note BS7671 Chap31 Para 311.1 states "For economic and reliable design of an installation within thermal limits and admissible voltage drop the maximum demand shall be determined. In determining the maximum demand of an installation or part thereof, diversity...

Taylortwocities Thanks for the link. I will try it

Wow, I can tell there is some contention over this ! Actually, I found him on Checkatrade. He has been the only one to respond to my job in which I stated I was replacing an old oven/hob with a 3.5kW oven and an induction hob, but needed advice on what max power hob he could fit could before I...

PROBLEM ! I had a local electrician look at the installation and I asked if he would certify my proposed induction hob. He would not. His recommendation, ie what he was wiling to do, was to run an additional 10mm-wired circuit from the CU dedicated to the induction hob, and use the existing...

Many thanks for your quick, and especially positive unequivocal responses. As a career engineer I really appreciate black and white solutions especially to the application of regulations! One final thing, do regulations (in England) require this installation to be connected or certified by a...

Hi, first post!!! Ive looked at other posts, some 8 or 9 years old when induction hobs were smaller and lower power. Modern hobs appear to have higher power features eg boost, ring bridging etc. I am hoping to install a typical 5 ring (80 to 90cm), typically rated 9 to 11KW. I wish to...
