Rendering in the winter

[Mr Blobby]

So, after frustrating delays all summer, the only option I now have for rendering this year is the last week of November.  Which in Northern Ireland means its cold, dark and wet.  

Do I reject the builders optimism and assurances and hold off until April/May?  Or chance it with the weather?

 

This is so damn annoying.

 

Block house. KRend HP12 base coat + K1 silicone.  No gutters up so walls are usually nice and wet.

No, just get it done. Ours was done in December. we only had a small area wash off. The silicone renders cure quickly, even in the cold.

Yep 

We render right through the winter 

The render will stand cold temperatures But frost is the worst enemy It needs to be 2 above and rising through the day Ideally scraped the same day 

Better to have your gutters on Even in summer

I agree.  I wish gutters had been installed, even temporarily, a year ago.  Walls are green at the valleys so I recently put temporary guttering up at the valleys.  Our builder doesnt seem to care about this. 

Down to me to clean the green off before the rendering is done.

If it doesn’t cause the render to wag off you will be left with a massive clean up job after the rendering is finished

I have been assuming for the last year that the gutters are not installed (brackets are in place) because the render needs to go behind the gutter at the top and gutters would cause an obstruction.  And so I have never questioned it.  I will ask the builder tomorrow why the gutters are not installed tomorrow and suggest that gutters need to be in place to protect wet render.

 

Are gutters normally installed before rendering?

[dpmiller]

will you have a fascia to fit or will will the render be stepped over the top board?

[nod]

Yes they are normally installed and temporary Down  pipes also 

But if the gutters and brackets are fitted directly to the render You will need to pick a dry couple of days
