    We wish to paint the floor screed in our property rather than lay floors - can anyone suggest process/ product type which would be suitable?

    You might have to do some work on it to clean it first as its normally not a mirror finish although it should be level.
    The floor will also need grinding to get rid of the crust that forms as it dries.

    Then you can use a two part epoxy.

    What would you recommend to grind the floor with - we're talking about 85m2 total?

    I'd suggest deciding what floor paint you are going to use and then following the manufacturer's instructions for a new floor of the type you have.

    Is the screed already down? Anhydrite Floor Screed might not be the best choice.

    My tiler did ours with a rotary grinder probably you can hire one.

    The amount of work you need to do will depend on how well its installed there can still be quite a lot of work to get a perfect finish as its normally covered over.

    I did ours with one of these attached to the grinder 4 1/2" grinder http://www.toolstation.com/shop/p62515

    It was the filthiest job ever with huge amounts of dust but quite quick and easy to do. This was for tiling so may not be perfect enough for a paint finish. Tried a belt sander but it blunted the grit very fast.

    This has been discussed before. It is the laitance (a weak layer that forms as it cures) you need to sand off.

    I used this sander http://www.akromultihire.co.uk/product.php?prodID=2593 it has a built in vacuum so some of the dust is sucked up. Used several fairly course grit pads that were like a mesh so they did not clog. I was sanding off the surface prior to tiling.

    I think you will need to contact any paint supplier / manufacturer as ask them what priming / prep is required.

    just look up two coat epoxy - mostly commercial/industrial but there are some domestic systems.

    When you search for two pack epoxy make sure your choice has the facility to mix colour to order, some don't. The good ones will usually mix to BS4800 or RAL.

    Anhydrate screeds are not suitable for a wearing surface.
    So I would put something other than paint on it.

    Such as?

    well obviously...but trying to avoid that. If I prime the screed with an appropriate product first then apply an epoxy paint will the floor surface become more resistant to abrasion and wear?

    Check the product data sheet of the Epoxy paint that you intend to use and the screed that has been used, but a quick Google certainly shows that some (probably all?) epoxy paints are suitable as a wear surface over anhydrite screeds.

    Might be worth a call to these guys.

    I bought our primer from them and they were clued up on anhydrite screeds.

    anybody know of a suitable primer?

    The epoxy I have just used did not require a primer on old concrete.

    Moisture is probably the most important aspect, the screed will have to be dry as epoxy does not allow moisture to migrate out.
