K Rend (Silicone TC 15) v Monocouche - on top of blockwork and external EPS

[AChristie]

Hi, I'm after some advice when it comes to rendering my house.

 

I have been recommended K Rend as a quality, low maintenance product, albeit at a premium price over sand and cement. 

 

When speaking to a K Rend technical advisor through emails, i was advised that due to the exterior of my house having both a combination of block work (new extension) and EPS board (over original building) as the external facing surfaces I would have to go with a Silicone Thin Coat - TC15 product.

 

K Rend told me that Silcone TC 15 was my only option and that ruled out their Monocouche product (K Mono).

 

I hadn't actually heard of monocouche, so don't know what i am missing out on. Is the difference between them down to  finish / colour / maintenance / price / install process? On doing some basic searching I can see Weber are a big name of Monocouche. 

 

I also don't know whether i should be considering any other product to K Rend TC15.

 

Any advice, or thought provocation would be appreciated. 

 

Cheers

There are a few more options 

You don’t need to go with a thin coat 

I’ve dealt with K and Webber K after sales are excellent Webber arnt

Thanks @Nod - more options from K Rend, or elsewhere? I spoke to my local K Rend contact today, he also recommendedTC 15 due to the mixed nature of my base layers.

I normally use LW1 directly onto EPS 

5 mil coat then mesh and an hour later 10 mil of LW1 Then scraped in the afternoon

I am going to be using aerated block. 1 Lime, 1 Cement, 6 sand, for mortar. Any recommendations for render over that @nod

Virtually any of the through coloured renders will go directly on to concrete block as it low suction

He is using aerated though.  Maybe needs Rendaid and mesh?

 So what is the main difference between LW1 and TC15?
