Painting Garden Wall Breeze Blocks

hoanymole

I am painting the garden wall tonight. It's breeze blocks and there is mixed advice around on what to do to prevent the wall drinking the paint and also to seal it.

Would you:

A) Mix PVA and Water and Seal the wall first before painting.

Or

Mix PVA and Water and Mix this with the paint?

If anyone knows the ratios of parts that would be great too. Thanks!

I painted the inside of a block built shed recently. Watered down the paint for the first coat, and you are right to worry, it wasn't easy. If you are using roller, you need a high pile one to saturate the block with paint to try and get all the little holes on the surface of the block - but I ended up using a four inch brush and did it just block by block by block. It was slow, but second coat was slightly easier and I might have done a third coat as well - but in the end I am really happy with the result.

Is spraying an option?

Power wash the wall first, seal it and paint it, two or three coats..

You don't use pva with any paint. Unless you spray the breeze block, which ever way you do it, its going to be hard. Thin the first coat of masonry paint down by roughly 40%.
Sheet up the area your painting because it'll be splashy. Depending on how deep the joints are you might be better off brushing in the joints and rolling the rest.
Don't be to fussy with the first coat just get it on. The 2nd coat will go on much easier. Buy a decent long pile roller sleeve.
