Painting Exterior Outdoor Wall

    I am looking for some advice re painting an exterior wall which is exposed to the harsh atlantic ocean, we live 3 miles from the ocean so the wall regularly gets a thrashing of wind, driving rain and hailstones.

    The wall is 40years old and the paint just seems to bubble and flake off, regardless of how it is applied.

    Its a 6" block wall, plastered, block on edge


    Any ideas ?

    I will be powerwashing with a 2500psi washer first so all the loose bits of paint will be blown off.

    Is there any worthwhile special paint I can apply on the now bare areas of the wall or am I as well off to just patch the bare areas with dulux weathershield.

    Post any patching of the wall, ill be giving 2 coats of dulux weathershield with a roller.

    Perhaps I'm just buying into the marketing but I would probably use Sandtex stabilizing solution first and Sandex paint for these conditions. There was also once a special mineral-based paint called Snowcem but it doesn't seem to be available in the Irish market anymore.

    Powerwash all loose paint. Add EB into first coat at a 8:1 ratio. EB is a stabiliser and bonder in one. superb product

    thanks for the advice, stabilizer isimportant I take it. the patches that the powerwasher strips back to plaster, do I need to go along with brush first and patch all those with a dab of paintbrush or 4"roller.
