Laying laminate in a new conservatory
I want to put laminate in our new Conservatory. The building was finished around two weeks ago, and since then I've had a de-humidifier running in there with a small heater keeping it at around 21deg.
The volume of water that the de-humidifier was extracting plummeted noticably in recent days so I thought that it may be ready to put laminate down. I laid the fibre board last night, but this morning I noticed that some of the board had curled up a little. Only very slightly, but enough to worry me. The humidity level in there is around 50-60% at the moment.
Firstly, should I have put a membrane under the fibre board? It seems to depend who you ask as to whether I should or shouldn't! Secondly, if the board is curling up is it too soon to lay the laminate? I really need to get this done so I can move furniture in there, because I need to replace the floor in the lounge (and I kinda wanted to get that done before Christmas...)
Sorry for the long waffling post... Grateful for any advice.
Fibreboard or leveller board is not suitable over concrete without the use of a dpm, it can also take much longer than expected for a new screed to dry, a good rule of thumb is 1mm per day or 10mm per week but that can be longer this time of year, the only true way to tell is to do a damp test.
