    Hi

    The outside windowsills of our house are looking a bit shabby with flaking, peeling paint. So I need to take off the existing paint an re-paint the tills with proper masonry paint.

    What's the best way to take off the flaking paint?

    TIA :)

    Powerhose and scraper I'd say. Clean them back to a sound edge. If you thin the first coat a little bit, it should soak into the concrete a bit better. Windowsills are a b@stard for flaking!

    A big problem with flaking paint on cills and copings is that even if you scrape off the loose flakes as soon as you start overpainting with a water based masonry paint the old paint starts to lift as the paint get under the existing paint edge! I would scrape back to as sound edge, feathering out the existing paint edges with a light sanding, dust down and spot prime the feathered edges with Zinnser Bin (shellac based) primer to seal the edge and help prevent the old paint from lifting. When dry you can proceed withyour masonry paint.
