which masonry paint is best over cracks (ed.)

[Joe1818]

Hi

I have a rendered wall and the previous owner has tried to repair cracks in the render but didn't quite get the texture right so the repairs stand out like a sore thumb. The render has an orange-peel rough-ish texture but the repair is smooth (see photo).

I'm wanting to paint over the crack again but want to get the texture to be the same as the rest of the wall - is it the type of paint I use or the roller that creates the desired texture on the wall?

I'm thinking of using either Bedec extra-flex elastomeric masonry paint or Johnstone's Stormshield Textured Masonry paint. Which one (if any) would give me the texture? I think I'd need a roller with a long nap?

Hope people can help - thanks in advance.

first off you want to sand back the filled surface so its less noticeable, then you need to dig out the crack a little wider and fill with a flexible external filler so it wont came back again in a few weeks time.

regards to roller, yes you'll want a long nap, the bedec will be a good paint.

thanks sxturbo - is it the roller or the paint which gives the right texture? will coarse sand-paper do the job or will I need something harder like a stiff wire brush? Lastly, what external filler would you recommend?
Many thanks for your time.

coarse sand paper should in theory be ok to rub the filler down.

regarding the texture, its various things that give the texture, the substrate, the paint and the roller.

unfortunately there isnt a guarantee you wont see the repair work, however it would look a lot tidier than it does now.
