K-Rend concern.

Hi experts.

During this covid period I had my house K-rendered. This was purely done due to the old bricks being painted over, some walls were pebble dashed and painted. I also had my windows changed so there was a lot of cement patches around the windows. It was all looking old and cracked, so I decided to change it up.

The company I used has been great, I also got them to do my roofing too which I’m really happy with. During the render process, I noticed some areas were not perfectly rendered. I could see circular shaped scratches from the scraper, some areas were not scratched correctly. I was on top of them everyday, infact one day they happily came back and rendered the entire wall again. After everything was completed, I started to see a shade of light patches in certain areas, not sure if the render is still drying, but it’s been a few weeks now.

Adding to the above, if I sweep my hand over the wall, the front layer of the render scratches off like powder. Should it be like that?

Upon cleaning the floor etc, the workers were using a jet wash and may have used some special liquid to remove any remains on the driveway, somehow they have wet part of my rendered wall, which is fine as I would have had to deal with it when it rains :) however, two weeks after I still see that area looking wet, only to notice its not wet, it’s a stained wall which feels rough when I touch it. (Before and afternoon pictures attached). Is there any way I can get this cleaned up?

Some pictures for you to view, hopefully you can see what I mean.

the rendering guys are probably tired of me going on and complaining about things. Not sure if I’m really wasting their time here. But at the same time I want it to look great. A lot of houses have been rendered around the area. But I’m the only one who has used K-rend material. Hoping I haven’t made a bad choice here. It’s actually quite stressful. And I’m just disappointed that I’m having to take my time out to stay on top of this. I’m a branding expert, so the finer details mean a lot to me.

Any help on what I can suggest to the renders guys would be great.

Many thanks.
Raj

The full balance hasn’t been paid yet. And they really do want to have a good review coming from me. I’m sure they don’t mind working on this again but overall I need to be able to tell them what’s going e wrong and how it should be correctly done.

What if it was already rendered to the ground, how would you go about that? Not having a go just curious

When you re render don't render down to the ground!
If the brickworks un slightly you can bead in different ways to prevent bridging damp and allow for sufficient gap to prevents dirt and rain splashes

Thanks Tom,

Based on the images I sent earlier, do you think it's still possible to work around the DPC. Want to avoid doing everything again. I'm thinking if there are any experts in the NW9 (London) area who can pop a visit and perhaps finish off the job... the way it should have been.

Thanks.

unfortunately with the shortage of internal plasters a lot of skimmers have decided to have a go at rendering... breaching DPC is day 1 week 1 of rendering...

The problem you will find is not many renderers will want to now go and try and fix because it then becomes their headache.

Anything's possible Raj
My guess is though through the quality of workmanship and visible errors from photographs your contractors haven't got a clue you have got rendered and painted substrates which all needs specialist attention and products butI bet they have just slapped monocouche straight on top of everything if this is the case it's inevitable your render won't last long at all
 
Omg golden rule dont render down past the damp course that wanted a drip bead probably in line with the door cill briged it there about 8 inches drawing damp up

Shouldn't there be a Bell cast at dpc though? Never done plinths, but surely their has to be a break between dpc?

There's no bead at dpc for a raised plinth.
The render goes straight down and then the plinth goes over that.
 
What you gonna do @Raj Patel ?
We can all see things wrong with it and commenting on them alone can make you depressed.

My view is your house should never have had that done to it even by the best pro team in the country. Should embrace a property within the era it was built not follow fashion and change its look so much, looks out of place in the street. I think works on the front of a property should require planning permission and be stopped from happening. It’s not just looks either but how’s work should be done too. Rant

People come on here asking for expert opinions and then just clear off, but rarely keep the thread going over the ensuing months about what action was taken and what results were obtained...
Keep us posted. One can learn alot from about how problems are overcome
 
I've come to this forum as I wanted advice from experienced members to see what has gone wrong. After reading the above comments clearly everyone has picked up on a lot of errors and absolutely, not only am I annoyed, but depressed and stressed about it too.

What's interesting is the other areas of render have been done perfectly, with no shades of different texture. Unfortunately it's just the front of the house that doesn't look as appealing.

It may be hard saying this, but I want to try and take the positive from here, I'd like to know how I can proceed forward with this. What next steps can I possibly take.

they have followed the correct procedure by doing aligning the angle beads and applying the base coat. Once dried applying the final coat etc. It's just the DPC and certain shades I'm not keen on.

The majority of your house was painted or rendered and painted did they hack off existing render? Was the paint Burns tested? Was there a pull off test? Did they use specialist base coats that are specified for going over paint? Was it meshed and mechanically pinned?
There's a lot goes into modern rendering Raj!!
 
Paint it With expensive paint
Cut groove at damp course height and fill with a plastic T shape trim. Never heard of it nor seen it done before because it is daft Idea
 
It's a poor job that one, leaving all above aside, stuff like the window cills not being right, beads not being level, the mess on the deck etc I mean look at the bodged bead above the bay window. It all wants rectifying then a stabalizer paint over the lot. Why not just replace the lead flashing on the pitched roof instead of leaving like that, it's stuff that a professional renderer would pick up on and not leave.

Hi Owls,

I agree the bead above the bay window could be much better.
The lead flashing on the pitched roof was changed when the roof was replaced. So it's all new.

what do you think could have been done better? I will be meeting up with the builders soon, so I can comment and give them my feedback on what's gone wrong, and suggestion on how they can improve it all.
 
External rendering costs a small fortune,
You've either accepted a really cheap quotation
Which would explain the state of the render because no respectable company can work to there high standards at cutthroat prices, or you've just been unlucky and charmed by a cowboy,
I would have it all off and start again with a proper specified system rather than having a camouflage job,
how much was you quoted?

I was quoted between £7k - £8k for this. Having it all taken off and back on again isn’t an option for me. It’s way out of my budget. I’d end up paying double the amount, even more with skip etc

I’ve heard good things about the k-rend brand. And I’ve seen some houses that have a k-rend finish. So it was something I wanted to go with. Any problem with k-rend?

Just a personal choice. I wouldn’t use it as I don’t like the product. Over bricks I would of gone down a more traditional method.

What reason is the plasterer giving for the difference in colour? Looks like damp patches in your picture.

Not when done right mate, which this is not.

Unfortunately, I'd estimate your about 40% on the way to where you want to be.
