Render Systems

[cork boy]

Hi

We have planning permission for a one-off house. The house is in a "period" style and we are considering the render options. To achieve an old style finish, it appears that the options are:

a. a lime render or
b. a monocouche system

Some of the monocouche systems appear to be problematic, from the point of view of mould and discolouration. In particular, some of threads on k-rend appear to be fairly negative. Application of lime render appears to be fairly specialised - also, where it is a breathable products, I wonder whether it is an ideal product for plastering over portland cement blocks which are not inherently breathable?

Does anyone have any recommendations as to how best achieve this type of finish? I read somewhere that mixing ecocem with portland cement will give a smoother finish? Has anyone tried this - how did it work - does it make much difference?

Thanks

An old style finish can be achieved using most materials, though K rend is probably the least olde worlde of materials on the market.
Just what type of finish had you in mind?

Hi legs

I am looking to achieve the look of an old style georgian house - slate roof, tall sash windows, door with overhead fanlight and side transoms etc.

As regards external finish, I am looking for a smooth neutral render. I understand that period houses would have had a lime render finish. Certainly, the difference between a cement render and the finish on a period house is immediately recognisable.

I am just looking for something that looks a little bit more authentic.

Thanks
