K Rend and other render options

[Mr Blobby]

We need to decide on render to go on block house.

 

Our builder is a big fan of K Rend, but I'm not so sure, having read horror stories about algae growth etc.  Also builder says he puts down a base sand/cement layer and then sprays K rend on top.  I did ask him about mesh to resist cracking but this doesn't seem to feature in his approach, leaving me a little concerned.

 

So what are the other options?  And then there are options within options, like monocouche, silicate?

What about sto, or weber? 

 

I have no idea about this so please help!

Did we have our house rendered when you visited? It's Sto, part silicate, part acrylic, can't fault it. If you need a renderer, I can pass you Kevin's details.

Your builder may be a good builder But he’s clueless about K Rend 

Sand and cement and through coloured renders don’t mix

All the renders come with the own backing coat 

I use Age-cide for staining Quick spray and the rain does the rest

@nod has forgotten more about rendering than all of us put together will ever know. But that hasn't stopped me trying to find out about rendering because it's a really interesting thing to do

(or in my case mess up).

I still know close to SodAll, but I can research Tinternet

 

 

This guy is really good at explaining the process

Thanks @nod, this is exactly as I suspected.   I like my builder but he does love to do things as cheaply as possible. 

 

You think K rend is ok then?  With the proper backing coat, which I assume is the first (of two?) coats over the blocks?  And would that typically have mesh in it? (I am neurotic about cracking)

I don't think your house was rendered when we visited.  It is reassuring that you are happy with the sto rend on your build.  I guess ours would have a different base coat on a block build?

Which sto product did you use?

Yes please PM me Kevin's details.

This rendering looks dead easy.  I think I'll just do it myself in an afternoon and save a bucket of cash. 👍

Which algaecide (I assume that's what it was) do you use? There's so many on the market.

@Conor would also appreciate Kevin's detail. Looking at Krend alternatives
