Any reason my plaster isn't drying

    Had my wall plastered and they finished 3 Fridays ago so it's had 2 weeks to dry but a certain patch isn't drying.

    It has had

    2 coats render
    2 coats tanking
    1 more coat render

    Where its not dried is a North facing outside wall about 2-3 foot thick.

    I had a heater in here ticking over at 19-20⁰c

    Could it just be that the wall is really cold so drying slower. I've got the carpet fitter coming a week today so could do with getting the skirting fitted but obviously can't until it's fully dry.

    It's a cold spot on the wall, try introducing a de humidifier as well as the heater.

    A friend of mine had a house done up, the wall was freshly plastered and ever so wet. He had heaters and several dehumidifiers for a couple of weeks, and it was not getting any better until he applied a "damp meter". It looked, but was not, wet. Hm?

    Do you have a floor standing fan? I find that just blasting such areas with air helps a lot. It directly warms up a cold spot.

    I have got one, we have been using a floor standing electric heater.

    It is quite a big spot though. Approx 3 mtrs long 2-3 ft high.
