I have masonry paint and brushes and am ready to go but wonder if there are
any words of wisdom and experience out there that can save me misery. Should
I use two medium coats or one thick coat of paint and what is the best way
to make sure the pesky little holes get covered/filled up ?
I think it will a tall order to get paint to truly fill the pores in
breeze block. If you want a smooth finish then a skim over with plaster
or filler or even artex for easy of application, on well dampened blocks
would be the way to go.
If you mean just to get good colour coverage then painting or spraying
with a watered down emulsion coat (10-20% water) to seal and then a full
strength coat. A brush or spray would be better than a roller on such a
Thank you Bob I am using your suggestion to water down the paint and it is
much easier to use and getting a reasonable finish, I am painting inside
stable walls and the horses don't mind if it is not perfect :-)
When the "little holes" are not filled and water gets in it is like
water getting into the borer holes in old exterior timber, it makes the
paint bubble and eventually come off in patches.

porous surfaces, masonry, concrete, old wood, weathered cement sheets,
aluminium cladding, kalsomine."

I see from your reply to Bob that you are painting indoors so it's not
as important, but for exterior painting on difficult surfaces it's well
worth getting whatever paint additives will make it grab, stick,
penetrate and waterproof because the one job worse than painting
difficult surfaces it painting them when the previous paint has bubbled,
flaked, and worst of all is still hanging on but unbeknown to you has
loosened its grip on the wall and the wetting and drying action of the
new coat of paint is enough to make it fail, visibly!
