Hi, Further to my recent post. I have decided to lay real wood floor over quarry tiles. I was going to prime tiles with P131 or similar, Lay a latex based levelling compound, 2 coats of liquid dpm, Mybe prime again?, Then lay an acrylic levelling compound. As far as installing the floor was concerned, wasnt sure if I should float/glue down the floor. I know a lot of people will have different ways of doing this but i wanted to know if anyonecan see a potential **** up occuring? :?
1- you cant install a surface dpm over a subfloor that has rising damp. The subfloor should be dug up and replaced 2- The latex compound will have to have a higher compression strength the compound going over the top. 3- As pointed out you cant use 131 primer on damp floors 4- solid woods are recommended to be glued in the UK.
It may well be the case that there is no rising damp in the house and the floor may be dry enough to prime.(The house has been sittng unoccupied for a while). Im not convinced there is rising damp. If it is the case, would my original idea be suitable, providing I glue the floor down and make sure the lower compound is stronger than the top? Its quite apparent that im no flooring expert, its just i dont fancy the job of digging out a subfloor. One other question is, If the subfloor is not suitable for the wood flooring, what is a suitable floor covering to use instead and how can I overcome the below standard subfloor? If there is a damp problem. Thanks again,Jack
Now i know that i will try and break down the info the best i can so you understand. If someone replies to tech then let us know. The forum your on is more dominated by the trade. We do welcome DIY'ers tho :thumbs O.k then, well the first thing you need to do is not presume. We need to do some tests on your subfloor to see if it is damp. When we know this we can advice better. First off i wont be trusting what your damp 'expert' has said. But lets take it as 'advice' to check the subfloor correctly. Now in your case this may be a issue. You will need a flooring Hygrometer. Its not the sort of kit you can Hire from your local HIRE shop. However you can hire through this forum. (PM me if you would like to hire through the forum) If you want to try and HIRE for yourself then you need to try and find a 'Flooring Hygrometer' Fball make them and so does a company called Tramex. We really cant advice you any more until you tell us what the moister content of your subfloor is.
Ok thanks for the advice Matt. I would like to think im in the 'Advanced DIY'er' category!!! :lol: Im also one of those geeks that pick up things quite quickly and retain the info ( usually the uselss stuff). I know of someone who runs his own flooring firm doing all the large companies, so I will wait for him to get back from holiday and ask advice. Once again thanks for advice, I will re-contact when I get definite readings.
