My floor is drying out nicely (helped by the warm weather), my dehumidifier has lifted about 8l of water out the living room in a week. So i have decided: I am going to try and scrape up the thin bitumen layer that held these plastic/vinyl tiles down. http://i27.photobucket.com/albums/c197/thomo123/20120719_215738.jpg http://i27.photobucket.com/albums/c197/thomo123/20120719_215748.jpg Then im going to surface dpm with Skia Rapid DPM - 3 coats. Soooooo....... What on gods green earth do i use to get this paper thin layer of bitumen up? **ps - has anybody used a product called Aquachem from a company called Rotafix?**
I've taken it off with a floor scrabbler. Not a nice job and it will pummel your subfloor. I've just got a tungsten grinding disc for my floor buffer to try next week on some bitumen. It is quite dry and thin layer
got it all up with a diamond grinding cup for an angle grinder. Took 3 of us all morning and the dust was horrific - but i now have a clean concrete floor to work with! (looks bone dry aswell.....hhhmmmm)
please excuse my ignorance - presume by water penetration you mean water being sucked up through the slab from the ground underneath? again please excuse - but if it was water penetration shouldnt i still see the slab as wet? I only grinded a couple of mm off at best? I am going to hire a damp meter from my local tool hire place and take some readings to see if it really is dry or just looks it. Also i am going to stick down some polythene and leave for 24 hours to see if any moisture pops up to say hello.
every day i have the same conversation of it "looks dry" Can some please tell me "what looks dry" looks like ? Its a bit like the test they did on driving speed. Everyone drives and looks at there speedo at 30mph or 70mph to tell them what speed they are driving it. In the test they removed the speedo and asked people to drive at what they think was 70mph. Easy ? well no, some people was driving at 50mph (lets call this a dry floor) and others closer to 90mph (lets call this a wet floor) thinking they was doing 70 mph It goes to show that something you do every day you cant judge without correct equipment to tell you (just like looking at a floor and trying to work out if its dry . It will never be dry as the humidity above will dictate this. The humidity in the u.k at moment is high so the floor is defo not dry, and even if low humidity then the floor will still not be 'dry' but may be at a suitable moister content to receive the new floorcovering)
my local tool hire do not do these and they tell me no tool hire will? Do u have an example of said tool? Presumably its not the cheap arse things that appear on ebay if u put hydrometer in? eg: http://www.ebay.co.uk/itm/Digital-T...pt=UK_Kitchen_Accessories&hash=item4161e02c01 http://www.ebay.co.uk/itm/Digital-H...ision_Other&hash=item35b52ede82#ht_3910wt_814
is there not a local floor layer to you that you can pay to do the test for you??? will work out better/cheaper than buying anything, & you will get the benefit of experienced opinion with the results etc
this is what you need - http://www.f-ball.co.uk/product_detail.asp?product=Hygrometer Kit&catID=damp You can phone them and purchase one. Should be under £150
if it looks bone dry it still needs testing ,what i mean is if moisture was being suck up from below it would show again after all your cleaning/grinding etc i still think the moisture came from a leak of some sort or water penetration from outside not from underneath if that makes sense, it just looked too wet.
