    Painting outdoor block wall, no render.

    I want to paint the wall with Sandtex or Weathershield.

    Do I need to prime the wall first?

    Nope. you'll need at least 2 coats. I'd advise using a sprayer.

    And power wash the walks first to remove debris, make sure the walls are completely dry before painting

    This question pops up a lot. It doesn’t matter whether you are painting blockwork or plastered blockwork, be it for the first time or repainting because the previous coating is flaking/peeling off.

    1. Remove any loose paint with a scraper.
    2. Power washing is ideal but not vital.
    3. Apply one liberal coat of this and allow to dry overnight or at least for a few hours.( No real care needed with this part of the process. It can be applied with a roller and tray very quickly.)
    4. Apply 2 coats of a good quality masonry paint.

    That’s it. You’re sorted.
