painting concrete block wall

[Pobolycwm]

Is there an easier way of painting a concrete block wall than brush painting ? I`ve got about 100sqm to do inside a kennels block, walls have been painted once before but they`re still quite rough.

Have brush painted about 4sqm and that took around 2 hrs to work it into the rough surface , can you use a roller ? ( what type ?) it`s what I`ll try next, want to use a good quality hard wearing paint epoxy / eggshell

I`ve seen contractors spraying them before on new build bare walls but they used a thin white, it was very quick though and filled all the "porosity / holes" on the surface

First choice: spraying. By far the most economical and quickest. Only down side is the equipment isn't cheap to hire.
Second choice: Roller. Use the thickest pile you can find.
Either option will require two coats for a good finish. Brush is not an option, to slow, use loads of paint and still a crap finish.

Thanks for that Spudler, will get a thick pile roller as recommended

Your welcome. Any bare surfaces will need a slightly thined coat first and take your time otherwise you'll be covered in it.
