Rendering in November/December

Haveagoer · 27 Nov 2008

I have to render part of the walls on the outside of my house and I am wondering is it ok to do this sort of job at this time of year? Will I need to wait longer than normal for drying?

The old render seems to be about an inch or so thick so the new render will be the same.

Any help appreciated.

so long as it is 5 degrees and rising then you will be ok.

drying times will be prolonged obviously, so this will be reflected in how much waterproofer you put in the scratch coat.

Indeed and much better conditions than a baking hot day with the sun blazing down on it.

Thanks guys. One last thing is i'm not 100% sure how thick should the scratch coat should be. Could someone tell me ?

as thick as you dare.

seriously, if you need to build-up thick, to an existing render then use the opportunity with the scratch coat to lay on as much as possible.

Cheers noseall. I have posted a question about "scuding" on a thread elsewhere on this forum but I may aswell ask it here instead....
Parts of the wall are down to the bare brick so do I have to scud the brick before putting on the scratch coat?

do you mean scutch?

if so then bare brick does not (necessarily) need scutching.

Thanks again, I'll go with what you say.

Just for info though the word I read was definately scuding, but the person who wrote it may have made a mistake.
Here is the link to where I read it
