Glad you've put this video up Blaine. I've been saying this about monocouche now for a while. The product is overpriced and has no longevity. Looks crap after couple of years
I have to agree mate…thanks for watching!
Hi Blaine absolutely brilliant video !!
I lived here in Spain since I was 8
Every building over here has stains if it’s monocouche or peddle dash,the Spanish also do not use fiber mesh so mostly every newly built house or apartments will crack
The standard of building and materials over here is not very good,
As the previous comment above said it should be sealed but they don’t even sell the sealer for monocouche over here so really the customers will nave to paint after the winters here but that just defeats the object.
It’s good to know your input since you’re living there. I did wonder if it was due to the sea air but your input implies that there’s a bit more to it than that!
Thanks for watching and thanks for the comment. I really appreciate it mate 👍
thank you for the informative video
Hi mate I live in spain how would you tackle big movement cracks in monocuche? Hack it out, seal it then re-monocuche and scrape back?
Would like to know how a professional would do it 😊
Great bit of advice here Blaine 👍
Thank you for watching!
Nice channel, nice video's and a good content!
Considering after watching your channel doing some plastering jobs around my house, just after some best advice one job is where double doors have been installed, so either side from skirting to about 12 inches ip is bare brick, slso slight gsp around one side, where the doors are slighlty spart from the wall, barely an inch,
The other one is i have had a gas fire removed so gap needs bricking and then plastered over, read will need an airbrick
What would you recommend? Im in a 1925 built bungalow in Kent. The brickwork in places is in poor condition and after speaking with my regular builder, he mentioned monocouche render as its low maintenance and doesnt need painting. (This video obviously contradicts that and has opened my eyes to potential problems only after a few years which isnt ideal at all. The cost of having brickwork repointed/ blown bricks removed and replaced is very costly due to the time and labour required. Ideally id like the bungalow rendered as ive just replaced the roof and modernising the property. Any tips would be greatly appreciated.
totally agree with you mate ! im the same always checking out finishes on hols 😁 interesting video !
Haha so true. We can never truly escape 😂 Thanks but watching mate
love this video, keep it up
Thank you for watching my friend!
im looking to render my home what render do you recommend s&c or silicon
Thumb's up for the honesty
Cheers mate!!
Can monocouche render be finished with a wooden float as aposed to a scratch float?
Have a nice holiday my friend!
Cheers mate 👍👍
what is the best render for a brick house built in the 30's with burst brick faces and degraded cement - looking for something with good longevity, insulation easy to maintain and for north east UK?
Spot on
Totally agree with you Blaine but it has colour run through it after a few years
Exactly that my friend! Thanks for watching 👍
I have seen the stains cleared before with A jet wash as apposed to repaint
Hi Blaine we use K-Rend HP-12 at work for smoothie tender also for K-Rends thin coats system. HP-12 is a dream
To work with anything you want it todo
It will do
Should try that out if your looking for a new render system
With the K-Mesh through it it’s impregnable
I’ll look into this! Cheers mate 👍
It’s a great system Blaine but it’s ment to be sealed within a month but no one offers it because its expensive and you’ve got o revisit to apply it
That’s good to know. Thank you for clearing that up…cheers Steve 👍
It's meant to have like a rain repellant over it that makes rain water etc... Run of it is that what your meaning @steveclements
I've used a product called nano drex protect £26 5lt. Good product
Bus man's holiday, I was the same 15 years ago when k rend was all the rage,but looking at how it ages doesn't look good still doing the traditional 😁
That’s the one mate 👍👍
Typical tradesman looking at your trade no matter where you go 😂
Interesting video though, lots of detail.
Hope you all had a lovely holiday mate. The bab seemed to be loving life bless her.
Haha so true Tara…it never stops lol! Thank you for watching and little India is thriving. She’s good as good!!
On my house I've used sand and cement with a top coat of 'heck silicone acrylic' from whetherby systems. Same as the silicone render you've been using. I know a guy that's been doing it for years and he's had no problems.
Sand and cement when painted traps moisture then starts bubbling up plus all render has algae growing up it you can use certain sealers after application to prevent it sticking but either way all renders give you problems
They all have their issues like you say. I think you just have to find the right one that’s appropriate to the situation 👍
Why are the White or off white renders in the UK are mouldy too?
They are using - lime / sand cement
This STO is nice
A lot of these systems have sealers. Which are applied when finished. Parex to name one. Water beads off it like you’ve waxed a car. I agree with the pricing of the certain wet materials, primers, paints, sealers. Mega bucks.
Moved into a house that had k rend on the wall next to the driveway, it's done exactly this! Ended up having to paint it which has held up OK so far
I’ve never seen a job where it didn’t do it to be honest. But maybe the comments are right…no one followed up with it like they should!
Maybe people should read about the products before using. Renders do require a periodic clean to ensure removing traffic film and atmospheric grime using PRB Actidemousse Flash for Algae and tough stains.
I was in spain for about 3 months and as you say the render on many houses is stained. I asked a British plasterer why they don’t use sand and cement and he said it wouldn’t work ( bullshit I thought). For the life of me I couldn’t find out what product they use for internal plastering. No one seemed to want to let you know like it was some state secret. Does anybody know.
Haha madness no one wants to share with you…it’s like a secret 😂
one thing, did you go to a seaside resort in Spain. or was you well well Inland??? as clearly the same thing happens everywhere near the sea no matter what you use....
It was a seaside resort to be fair matey 👍
Hello
Great video but too late for me as I already have monocouche render that is looking really terrible now--blackened with algae. How can this be (a) cleaned and (b) treated or painted to reduce the problem in the future? Thanks for any advice.
You need to softwash it. Dont paint it
@@Jhhhf4479 why do you advise against painting it? also, it seems that there is a sealer available: would you recommend that, and would it need to be cleaned regularly even with a sealer?
@Ann O'Nimus they require special paints and you stuck with it. I'd try a specialist cleaner like Softwash, not power washing. It is cheaper than painting. If that doesn't solbe the issue, maybe consider painting.
@@Jhhhf4479 thanks -- what do you think of the sealants? will a sealed exterior discolour in the same way as the unsealed render?
@Ann O'Nimus I think it depends. You might get free sample and do test on a hidden spot
Been saying it for a while Blaine. Looks great when it's first done and fresh, and then it doesn't weather very well at all. Especially where I am in Derbyshire. It looks awful after a while.
I don’t think our climate is geared up for it! It’s just too wet here!
I don’t think our climate is geared up for it! It’s just too wet here!
It all depends on the product and the sealer you use after if people price job properly then its all in one price for customs my business is mainly rendering now as so many people love the products
👍👍
I’ve visited Liverpool ONE today. The monocouche is looking shocking 5 years down the line. Can it not be jetwashed?
It can be jet washed
Yeah I seen that - looks awful Doesn’t it! You can jet wash it but the cause is still there which means it’ll keep returning unless it’s painted and sealed properly. Shame really
Interesting video Blaine, what about K Rend as a recommendation , as far as i know that is a two part system .
Thanks mate. K-Rend is a Monocouche Render…it’s just the brand 👍
U can also float and sponge krend so u get the best off both worlds
I didn’t know you could float and some Mono - that’s Perry interesting to be fair. I wonder if that would make a difference??
A lot of those same buildings in spain would probably look crap in thincoat silicone too if the details of the build don’t protect it. Poor overhangs, lack of movement joints etc.
Iv seen new build timber frame buildings done in silicone over here that look shocking for this reason.
Yeah mate, you can see it everywhere. I'm a big fan of repointing the brick.
Why do we apply the texture on K rend then, can you just leave it flat?
That’s a very good question pal!
@@PlasteringForBeginners Be great if we could float and sponge it?
I was wondering if there was a way to close it as a finish as the holes scratching leaves are only going to invite problems.
I've been living and plastering in Spain for 20 years, we call it raspado over here, you can sponge float it but it still leaves quite a scratchy finish, morcemsec capa fina is the way to go, probably what you guys call thin coat render
Use weberend protect, great stuff, no staining with that.
Thanks for that! Cheers pal 👍👍
You can buy sealers for it
Silicone render?
Had Monocouche on our property for 5 years now and it looks dreadful. Why did I pay a premium for colour through render which I was told would never need painting? It has cracks, loose patches and holes where oversized aggregate has fallen out and is badly stained by weathering. Any attempt to repair this coating stands out a mile.
That company has got the market sown up clever🤔
We lived in Spain for 3 years Blaine, the build quality of the houses isn't great - that's not to knock the tradesmen there, but the way the houses are built - particlularly for weather protection is poor. They do have a wet season and our house was horrible in that period, damp, cold, draughty - and at 13 years old, it was already full of stains on the render.
I worked on a job where the owner had his house re-rendered white, and the first spell of red rain we had (when the dust from the Sahara falls with the rain), left the gable ends of the house covered in red streaks which wouldn't wash off even under pressure.
God that’s mental!! Imagine paying all that money to be left with a building with red streaks everywhere! What a shame for them.
Thanks for your insights - it helps massively. Cheers 👍
I also don't like it when it's dirty....but just clean it?!
Tried and tested is always the best route to go down .
If it worked for grandpa , it should work for his grandson too .
Nice place !!!
By the way , where's my card ?😊
Exactly that my friend! Thank you for watching 👍
👍👍

First off, thanks for all your informative videos ! It seems your beef with monocouche is NOT with monocouche but with the scratched finish - monocouche is not a product per se (in the sense that we know the composition), it's type of render that lends itself to an application method (i.e. it literally means in "one coat", as you said). You can apply a bunch of different finishes with various monocouche renders. You mentioned good old cement renders but these can be a disaster for many traditionally built houses (eg. using soft stone) and many restoration jobs have ruined old houses because they've used cement render, which is harder than the stone/brick, and so cracks them under thermal expansion. Cement based renders can also be the cause of huge damp problems in walls that need to breathe. Wall prep with antifungal products followed by proper sealing after rendering can solve the fungal problem - but it's more time, more cost and so if the customer is none the wiser, may be skipped by unscrupulous tradesmen. Otherwise, the fungal problem can be addressed if and when it occurs through the use of appropriate washes.
A plain face sand/ lime/cement finish painted with a good quality masonry paint looks better and will stay clean I am a 76 year old retired plasterer with many years of experience of most types of external rending
The problem with anything waterproof and that goes for paints also, is that whilst it doesn’t let water in, it doesn’t let water out either. The binder with the highest capillarity and vapour permeability by a long way is quicklime. (See Tarmac Calbux 90) Different to hydraulic lime that K Rend is based on. Hydraulic limes do not stop hardening over time or have unpredictable hardening times and set way harder than they are supposed to thus limiting breathability.
That’s very insightful Michael. Thanks for sharing - cheers pal.
You can have a smooth finish with monocouche, you don’t have to scratch it.
I didn’t know that. Interesting!
I absolutely hated the stuff when I was plastering.
👍👍👍
England has the wrong weather for it.. total shite here.. never got into it.
Started in 97 watched it come along took one look and ..No
I started out using lime based and cement based renders.. stuck with em.
Very true Steven - sounds like you’ve seen the progression then. It’s not my cup of tea but I can appreciate why people use it 👍
thin coat render, best render system by far
I do love thin coat Render!
Little people are pretty great!
Haha they are!
Looks lovely at first but discolours badly. The thin coat system is far better, nowhere near as open and less pourus.
I totally agree mate!!
All render is rubbish,they all have their own problems.old school sand cement render with tyrolean was the only thing we never had problems with.
i only do s&c, to jazz things up i do a colour tyrolean from weber
I think they all have their uses but I do sometimes wonder if finished brickwork is the best option. It depends on the circumstances I suppose!

Used to do a lot of tyrolean years ago proper work out hand balling it on done a few spraying it on lot easier and a great finish totally agree with you👍
Apart from the cracking, just use silicone thin coat render job done.
I know your going to go towards thin coat silicone render here. It's silicone based but say your working on a lime substrate I wouldn't advise you to use it as the property not be able to breath so then there's another issue.
With mono if you use the correct 1 for the correct climate and seal it as advised you'll stand alot better chance mate.
Issue is ppl will use weber in UK that's not made for our climate etc... Then moan about it etc..
there's pros and cons to all renders 1 way or another.
I love silicone but like you say, I wouldn’t use it in all circumstances…plus it’s expensive to be fair. It’s just about finding the correct product for the situation 👍
@@PlasteringForBeginners totally agree mate. It just sempt like you was trying to rule out mono all together that's all.
I get what your saying regarding staining etc.. Also but as we have both mentioned the correct product is time and place and used correctly it can all work imo.
Plus call a apple a apple all said and done silicone thin coat is a tyroleen upgrade let's be honest.
Easily cleanable, dont see a big issue
Thin coat all the way
Just paint it, like sand and cement render.
You simply cannot beat brickwork 🤷🏻♂️block and render is false economy
You might be right mate!!
Yes best for the UK .
If you think Spain doesn’t get much rain your on acid
monocouche is just a bad product people stick to cause its cheap, silicone render is 10x better.
Wrong about the paint lad! Any exterior paint works! The way to avoid staining is use “Weber Protect “-“Paraguard” etc stop slagging my living lol🤯🙈😂
