So our garden wall is block with no DPC. It's in decent condition, but I want to paint it (bare at the moment). Prime and then masonry paint? The worry is rising damp...

Rendering it is too expensive, as we are going to clad it in teak panelling for growing plants. Just want to make it look not awful...

If you're going to clad it, why paint it? We went with Marley Cedral Click instead of wood, it looks good and needs no maintenance.

If you paint with masonry paint, you could use a mist coat and then two full coats. We did this on our rendered garden walls, and on some of the bare brick, but it does bubble and lift off eventually even if you do a coat of waterproof black stuff (can't remember the name). Then when you scrape off the loose stuff and repaint, it looks worse as you can see the edges.

This stuff should the trick, albeit expensively, however, as stated above why paint it if you're going to clad it? Zinsser watertite

It's around 12m long, and ranges from 1.75 to 3m high (our garden is stepped).

That's about £1k's worth of cedral excluding any trim pieces, battens, membrane or installation.

I know - but rendering it will cost similar...

Slapping some paint on obviuously cheaper, especially as the house is going on the market...

As long as you have a good quality masonry paint you should be fine for a fair number of years.

I tend to paint rough surfaces with a stippling type of action to get deep into the imperfections, then brush across normally afterwards.

If you're going to grow plants over it then cedar cladding may be overkill and instead you could use some wooden trellis work?
