Garden wall K rendered ghosting. Paint?

[houstonwehaveaproblem]

Hi all

Our blockwork garden wall was rendered with Parex a couple of years back and it gets some ghosting appearing through the finish.

Can some type of paint over be used to hide the ghosting? which type?

Not ideal I’m sure.

Retaining wall?

OP,
Whatever kind of wall you are referring to then can you post pics of the wall?
Dulux exterior Textured masonry or render paint is expensive but it will cover a lot of sins.

Dulux exterior smooth masonry or render paint won't get so dirty - because it's smooth

hi yes it’s a retaining wall. Garden is higher up than patio

The Textured Dulux goes on thicker than a smooth Dulux, &, of course, a thick masking paint is what you need for that wall.

Unfortunately, there's no signs of moisture coming through the weepholes which might mean, depending on how the wall was constructed, that the pressure of the water is penetrating straight through from the other side?

Did the builder put a dpm against the wall before backfilling?

They did fit a DPM behind the wall.

Moisture penetrating the render soaking the perp and bed joints.
A decent paint to stop moisture penetrating the render should do it.

Thanks

the wall is rendered the same colour as the house. I had a quick look and i think the manufactured (Parex?) Do a paint to match the colour. I think.

Those capping joints look like that may be where the water is getting in . Ree point or seal them and hold the painting.

I just checked some of the weep holes and a few are blocked with render
