    hi guys,

    I hope someone could give me an answer regarding the issue I am facing.
    I am doing a bathroom refurbishment.

    I initially got there to fix a leak, however the walls were soaking wet. I have stripped all out and let it dry via a strong fan and a dehumidifier.
    Now, I have plumbed all in and the tiler have put the liquid rubber - tanking / ardex onto the wall. However, he started tiling yesterday and used the mapei flexible adhesive and when we came this morning, it was still not fully dried out. The problem is the bathroom is like a box room and has only a window which has a fan installed the window screen. You cannot open the window to get a draft.

    The adhesive just doesn't see to set and dry out. What can we do to make that happening ? What did we do wrong or better the tiler?

    Is there anything we could have done better? The problem is there is no draft and it's always very humid and moist.

    Kind regrads

    Ron

    Heat to evaporate moisture,dehumidifier to remove it. Even though it is a very damp environment, the adhesive should have set. Others more knowledgeable in such things will no doubt be along to offer ,advise. You say your tiler used Mapei adhesive, was it standard set. What type of tiles did you instal. Presumably you haven't grouted yet.

    That's what we do tomorrow morning. It's a little pain as it is a council flat and I really don't like doing bathroom refurbishments in flats. It is always a pain either tilting or plumbing - never easy

    If they are porcelain tiles there is no where for the moisture to go, it will take longer to dry.

    Hi Ron,

    Based on the information supplied, Mapei Adesilex P9 is a standard setting adhesive which take a minimum of 24 hours to cure, however this can potentially be affected by moisture or temperature levels in the environment.

    In this instance we would advise leaving it another 24 hours with plenty of air flow to help remove the moisture to aid in the curing process.

    We hope that this information is of benefit to you and if you require any further assistance please do not hesitate to contact us on 0121 508 69700 (option 2)

    My tiler has finished to put all the rest tog tiles up. Do I need to wait 24h to prior to grouting? Ideally I need to finish the bathroom today. However due to the tanking ( Ardex ) we cannot fully grout as the last 2 rows are done today ? Is that correct or are we able to put the grout ?
