How would you advise on this render

[Olican]

A client has rung asking advice about the render on their new persimmon home, they are concerned that the ghosting and if this could cause problems down the line. How would you advise?

Clemo.s got a therory on this .

There’s no way the builders will pay for it to be redone if that’s what customers asking.

looks like too thin. see shaddows of the blockwork. im guessing blockwork joints were still wet when render applied..

That's what I was thinking Dan, the owner is concerned about moisture ingress. I think it's more of an aesthetic fault

Needs sealing once it’s dried out fully. Mortar bed retains water longer than the block.

what is that crack down the gable ? surely they did not put a stop bead on that little wall .

Could be the block work was soaking wet when applied. Its sucking more on the mortar joints hence the block work affect, or to thin, I’ll live in Barett home and see loads of this on my estate it’s shocking, can’t beat good old sand and cement done properly

 

[Ritch]

This is the best one on my estate not a barett this was bovis one lol

McCarthy’s firm did them by the way, think Torquay way lol

 

[Ritch]

There from Torquay I think

More than likely, they do most of the spraying round here

That'll be an expansion bead Malc. Any wall over six metres should have one no more than three metres from the corner.

Let it dry and coat it in Stormdry. You won’t get that effect when it can’t soak up water

 

[essexandy]

Personally I think something hasn't been done to the correct spec or there wouldn't be this ghosting. Whether it's the render being too thin or the blockwork not having been allowed to cure/dry before rendering, it's still the responsibility of the builder IMO. And probably wouldn't take a lot of proving.

I'd advise a thin coat silicone render over the top with 1.5mm finish.

 

[martinemj]

Typical house builder quality

 

[Rigsby]

Its too thin and probably was done on a soaking wet wall. A high performance silicone paint will sort it.

[superspread]

Nobody said it wasn’t one coated. People are suggesting ways to resolve it not wot went wong

All I’ve read is the block work is soaking wet etc etc!

 

[superspread]

I was a bit pissed as well

 

[Vincey]

Could clad the top

It's not a theory we have tested it. To mush plasticiser in the brickies mix will make it happen. Render on to Tin can make it happen to or the block joints holding water when rendered can to. A good scud coat can help stop it. But if it's full of concentrated fab it's a c**t.

That's really interesting Keith, I've always been really really particular with my render mixes, everything always measured and gauged. Always consider the substrate and it's strength. I think a lot has been lost with mortar work; when you see a lab throwing Feb in with no thought
