    What length of concrete screw would I need in order to secure a 37mm batten onto a concrete ceiling which has a 10mm layer of plaster on it?

    The battens are required so that I can dry line the ceiling to cover electrical trunking following a rewire.

    Would suggest that the thickness of the concrete ceiling also needs to be taken into consideration before deciding on screw length

    The concrete that forms my ceiling and floor of the flat above is 200mm thick.

    Perfect, if you can't get 90mm, then use 100mm.:)

    Thanks for all the answers.

    One more thing I need to know. I'm going to fix the battens at 400mm centres but how far apart should the screws be along each batten?

    Start the first one in about 0.3m then about every meter.
