Patchy/drippy KRend, what went wrong?

Good evening folks,

I wonder if anyone might be able to let me know what has caused the top coat of KRend on our house to look so terrible? The colour varies hugely in places, there are "drippy" areas where it looks like the colour has run and in some areas the block work is showing through. Most of it was applied in the winter and our builder used an accelerator to speed up the drying. He says he used the same batches of colour and that it'll all dry the same colour eventually, but I'm not convinced as it's been on for 5 months now.

Any advice gratefully received

That is the worst job I've ever seen looks like he sponged it up with loads of water it should be around 15mm's thick with a scrape finish it will never ever be one colour whoever did it totally f**k*d it up he did have a clue what he was doing

What product is that? It looks like lime render with formed corners. Was the house stone originally?

If they've done that over block that's wild unless you wanted it not to look modern and wanted a cottage look?

It's a strange one

Call a rep dovey from the product manufacturer before you speak to the builder again, it’s absolutely shocking sorry and him telling you it will dry back one colour are lies I think this one will be for the small claims court

Most reps are trained to not actually say too much in front of the customers so don’t be surprised if he’s not a huge help so ask questions about the base coat he should have used, the overall finish, any areas of dpc that may have been bridged any corners that should have been reinforced with beads should he have used a reinforcing mesh, just to try and get answers, if he sees any visible cracks he may test it with a feeler gauge to test for thickness, I’m pretty sure the rendering manufacturer are only looking for any voids for any sort of warranty and the contract for any remideal works are between you and the contractor Krend won’t deal with it on you’re behalf

If you wanted a cottage style finish it and he hasn’t bridged any damp course all it needs is the builder to come back and repaint the house because it looks like he did when it was raining or like been mentioned above too much water

Hi all, thank you for taking the time to reply. When they started the job he said they'd sponge it to keep the "cottage-y" look but having now contacted KRend I understand that it's meant to be scraped and should never have been sponged. To my untrained eye the result isn't even "cottage-y", it just looks quite messy... am I right? The block bit is an extension and doesn't really warrant a cottage look either. He's saying that the joints take longer to dry and that's why we're seeing them now...

Also, they used Weber as the base coat and KRend as the top coat as he said they are both lime based and compatible (there was a long wait on the Weber top coat)... is this correct?

The original cottage was "dubbed out" and then had 2 base coats, mesh and then 2 top coats and he's saying that's why it's all uneven as it's taking so long to dry. However the colour is so uneven that some parts almost look white whereas the whole house is supposed to be KRend "Cream", not even taking into account the drips (are these from laying it on in rain or from the sponging?).

Sorry for the long post but I'm feeling like a complete mug and don't know what to do next. The hacking off took so long and was so disruptive I don't think we can go through that again and I feel sick thinking about how much money we have paid for something we're really unhappy with

What qualifications do you need to be a builder?

Technically, you don't need any specific qualifications to become a builder.

The builder is talking s**t he's f**k*d up completely on the render weber base coat and k-rend top coat wouldn't make much of a difference really they should be the same brand really it wouldn't be guaranteed that's all the job is a complete mess I wouldn't have given him a penny

The idea was to have coloured render so that we wouldn't have to repaint it every year... the house is very open to the elements. However we obviously are not experts... live and learn hey ☹️

Its not the end of the world
Coloured render does not need painting correct but it goes mouldy anyway
It is like a marketing thing to sell products like self cleaning glass lol

If it was dubbed out there shouldn’t be a need for two base coats one would be enough for mesh, if they have said they have fully meshed the building did they charge for it? The stains are water damage they have screwed up and done it in the wrong weather

How the f**k can the builder look at the first pic and say it’s drying uneven when there’s white lines running down the wall
