Hi there,

I'm a little confused by the different types of render and would like some help to decide on the best one for my needs please?

I'm in the process of renovating a Victorian semi in South Wales and am hoping to get it rendered in the coming weeks. I have had the old render hacked off back to bear brick and this is rough to say the least! I've also got a new blockwork extension to render too. The brickwork is around 150 m2 and the blockwork around 50 m2. I hate painting so am looking for a coloured render. The walls are solid brick but have been insulated and dry lined internally so an EWIS is not needed.

When I first started thinking about it I thought a coat of k-rend (it was the only one I had heard of!) and all would be sorted but now I'm not so sure!!!

The plasterer who is doing the inside had a look at it and said he would need to give it 2 scratch coats then apply the monocouche, but wanted to charge more than £26 m2 for labour alone which, since he can only do weekends, seems a bit steep?! I then spoke to a company who specialise in pumped render who said they would give it a pumped coat of base coat and then pump the monocouche. That company said they wont use k-rend anymore as they have had loads of problems and suggested webber instead. Then I was speaking to a friend of mine who is a plasterer and is currently doing lots of EWIS work with an acrylic thin-coat render and was saying that it was excellent stuff, I've read a few posts on this forum where people have suggested OCR then thin-coat but I'm not sure how suitable it would be.

So my questions are:

1. Which is better thin coat acrylic or monocouche, and why?

2. Is thin coat more expensive than monocouche?

3. Is there such a thing as OCR for rough old brickwork or would I still need a scratch/base coat?

4. Can anyone give me a rough idea of what I should expect to pay?

Thanks in advance for any help, it is very much appreciated :-)

Hi Fatarm, can the wallcrete be used to give a smooth or slightly textured finish?

Inside is sorted, just using standard board finish! Thanks
 
1. Which is better thin coat acrylic or monocouche, and why? Acrylic, more flexible

2. Is thin coat more expensive than monocouche ?.. Yes

3. Is there such a thing as OCR for rough old brickwork or would I still need a scratch/base coat?...Yes

4. Can anyone give me a rough idea of what I should expect to pay?...​How long is a piece of string

Thanks in advance for any help, it is very much appreciated :-)

Get quotes from reputable rendering contractors is your best option , a quality base rend mesh and acrylic is the est option , but you will pay a premium, imo

Hi warriorupnorth, thanks for the reply:RpS_thumbup:

Just a few more questions if people don't mind, I am liking the idea of the acrylic thin-coat over OCR. I've had a look around the forum and done a bit of googling and am I correct in thinking it would need a coat of rend aid over the whole house to kill some of the suction in the brick and equalise the suction across the brick and block work. Then a coat of something liker webber OCR followed by the thin coat?

Is webber the best system to use?

Is it possible to pump the OCR?

How much is a bag of the webber OCR?

Thanks, Tom

Why would it bother you if OCR can be sprayed ,rendaid out then mono ,well that what i would do .but it,s your house !
 
Thanks keithuk, but can you explain what you mean by rendaid out then mono? Is that mono as in monocouche? Are you saying monocouche is better than thin-coat acrylic?

Thanks
 
Thanks for the info madmonk, a few people have suggested meshing the whole building which seems like a good idea but would the mesh go in the rendaid layer or in the OCR? Thanks
 
hello Tom,
Where in south wales are you situated. I am based in Swansea,am a plasterer and have a depot there. We have a small display wall out front where you could see live samples of the render finishes and systems you have described. I would be glad to meet you there to assist with any questions. Should you choose a render suitable for your need i can probably send you to a property we have completed for you to see the finished product. Many times we have photo albums of work in progress so you can view the work involved. Our website Plastering, insulation and rendering in Swansea | Jones Plastering should give you our details for contact
 
When you are using any form of colour render use a company that does it day in day out ,when done right it looks the business trust me ,best of luck

Theblones certainly knows his stuff! Look for his youtube video's.

As for mesh then I would mesh the rend-aid and at least the stress areas in the ocr but Weber is not the only manufacturer. Parex and Marmorit is another manufacturer with excellent reviews on here.
 
Hi theblones, my house is in Merthyr, do you come that far up the valleys?

keithuk, thanks for all of your help :RpS_thumbsup:
 
I'll take that on board Rigsby, I suppose the manufacturer will depend on what the person doing the rendering prefers but I'll defo have a look at the Parex and Marmorit websites. Cheers
 
Yes Tom Merthyr isn't far from Swansea. Perhaps if you email some pictures over I can give you some costings of various systems. If they are within you're budget we can move forward with a meeting and help you decide what to have as a finish and what preparation is required

SAS Europe is down your way, they have an excellent ocr and synthetic finish. If it is getting late in the year consider their rapid, it sets in 3 hours at 5c.

Hi Everyone,

I'm based in Southampton and had my heart set on K Rend until I found out about Monocouche. Can anyone advise about the Webber ? I had never heard of it before reading this post and am interested to get the 'right' render on my house. I like the texture of K Rend but often I see posts where professionals struggle to apply it and I had always though it was guaranteed for 25 years but it appears that it is prone to cracking and it is difficult to repair.

Any advice will be very much appreciated.

Many thanks,

Lauren

A monocouche render is a through coloured polymer modified render, k rend is that plus various others weber
, parex etc there just different makes.
A professional will not struggle to appply it if they are familiar with the application process and the product in general.
You will get bad and good feedback from people depending on there opinions, on said product.
There is nothing wrong with k rend if its applied right, your render is only as good as your substrate, as most things preperation is key.

Through coloured renders are difficult to repair and blend into the original, but you shouldnt need to repair it on completion.

have a look at the render manufactorers websites for more information.

Monocouche (one coat coloured mortar) should be applied with no real problems by a pro as OWLS says. The famous brands are all much the same - Krend silicone ft - weber pral - parex monorex - etc its all monocouche though some do have more goods in them than others that have more bulkers in them like excess sand/glass etc. speak to an applicator rather than judge by the brands website because I find thats what happens when clients are hell bent on one particular or because a builder told them because its on the shelf in there local supplier where they account.

I also find the better products are actually the better priced ones on the Square metre coverage

hope this helps.
