Awful rendering job - what can be done?

Hi All,

I posted back in October about an issue with the external rendering for a house I was in the middle of purchasing. There was some really good suggestions as to what was causing the issue, and I passed these onto the developer who has done nothing about it ever since!

So I need to know now what can possibly be done to rectify the issue, is there a quick fix or will the rendering have to be done again? If the rendering does have to be done again, does anyone know what I would be expecting to look at in terms of cost for London?

I've attached pictures for reference and any suggestions would be much appreciated, thank you!

Thanks mate, yes those were the suggestions. If those issues are resolved, will the rendering need to be redone do you think?

I’m just a clown on here - my name says it all.
I would not comment strongly myself.
@Rigsby @church are who I would ask advice from (no offence to others) and @church did give you his comments already (I just looked up your original post)
People on this forum are not really a free advice Service especially when it comes to large specialist projects which can’t be adequately assessed on a small social media post so you get scraps of opinions. Some good, some bad, some wrong, some bang on!
I think the main thing is the visual impact isn’t it. You see unsightly water staining and your brain worries and goggles and believes it is a fail. If the render is sound it will last a long time. Freeze thaw cycles will slowly damage the integrity and eventually it will detach in patches but we could all be dead from COVID variants by then?
I can’t even tell what material that is? Is it sand cement lime? If so base coat highly likely has a waterproofer in it so you’re (@Dollar) seeing hairline cracking on the top/float coat which is showing the water ingress extent in full to the eye. These are somewhat inevitable to eliminate from happening completely. As easy as water goes in it too will evaporate out again. Sealing and or painting with a quality product should totally end that from happening. But then can trap water in lol between paint and waterproofed base! But hardly?
If your material is not sand cement lime then like I said - I’m just a clown :X3:

No that's great, I appericate your comments and those of others as it gives me some knowledge to go back and dicuss things with the developer without getting completely blindsided!

That's exactly it, the brain sees those unsightly water marks and panics it could be something much more problematic, also it's my first house purchase so probably being more paranoid than one would normally.

It's limestone rendering, apparently the council didn't allow them to use K rendering due it not being visually acceptable with the general village feel or something. I'll suggest the waterproofing (sealing) to the developer and see what they say. Thanks again for your time and hopefully I'm able to get the problem recitfied before any new covid variat gets me!!

Is this a lime render? If it is its been rushed.

A silicone paint will probably be a cure but then maybe only temporary and the Council may not allow a synthetic coating if they insisted on a lime render.

investigate those copings for drips and damp proof membrane then if you do it again get a spec and someone who can apply lime render to the required thickness and will allow curing times between coats.

Thanks for your reply Rigsby and yes it's lime rendering, definitely agree with you there, it looks like it's been rushed!

I'll be passing on the suggestions to the developer and hopefully they take note! Initially they said there was nothing wrong with it but now they've acknowledged it as being an issue but not yet said what they plan to do.

By the looks of that type of building why was the need to use lime render ?

The developer said it was because the council said something about the building needed to be in line with the rest of the village aesthetics and that other types of rendering wouldn't achieve this.

If the lime render has been “rushed” - hard to do given setting times - then we might suspect that a white cement has been added to speed up setting times. This could be detrimental to the efficacy of the lime render, lead to shrinkage cracks and give the visual effect you display. You might be able to “lose” the cracks by applying a lime wash. However all sane men are aware that turds seldom take polish well, glitter however is another thing. If funds allow - do it again, properly.

Hi @Newbie1135,

If you are looking to get this redone then please do not hesitate to get in touch. We at PRB systems have a pre coloured lime render system that you would be able to use once this render had been removed.
We have over 100 different colour options to choose from that are available in as little as 48 hours (depending on the chosen colour).

We also can provide you with a list of Pro Contractors that will be able assist you in carrying out the works and show you evidence of previous works carried out for your piece of mind.

If you require any information please do not hesitate to get in touch.

Kind Regards

Iain

newbie,
your cheapest solution for the cracked render would be the apply BDEC extra flex masonry paint. i have seen this paint used on your type of render it still looks good after several years. don't fill the cracks just let the paint cover. have a look at the BDEC web page.
