Pocster Posted October 17, 2017 Share Posted October 17, 2017 Hey all What do I do about expansion gaps ? Do I just leave a few mm between the board and soffit for example ? also how long long can the board be left attached to the build externally but not rendered ? ( if not long is it ok to cover it in polythene for example ? ) cheers Link to comment Share on other sites More sharing options...
Pete Posted October 17, 2017 Share Posted October 17, 2017 You need to decide on which board you are going to use and get the fitting instructions from the manufacturer as they do differ quite considerably. What are you putting on top of the boards? Link to comment Share on other sites More sharing options...

Pete Posted October 17, 2017 Share Posted October 17, 2017 You need to work back from the outside. Decide what render then see what board is suitable.It is a nightmare as they all differ in some aspect of fitting and if you do not follow their requirements you stand no chance if you have a problem later on Link to comment Share on other sites More sharing options...

It's not just board and get any k rend guy ( or similar ) to do it then !!! i guess I thought of it in the same context as a plasterer .....

lizzie Posted October 17, 2017 Share Posted October 17, 2017 We are using a silicone render...its part of an alumasc vented facade system specially designed for timber frames, its v expensive but has BBA cert and guaranteed for umpteen years. Being fitted by specialist contractors and is currently in the process of being done. Glad we are only doing part of the house in render its massively more expensive than larch!

bassanclan Posted October 17, 2017 Share Posted October 17, 2017 You are obviously allowed to put the boards up yourself, but I wouldn't start until you know the cost of getting an approved contractor to do it. (I just means they have done a days free course) as you will have the peace of mind of a warranty. You can see one possible issue by not having sufficent gap in this thread.

I wouldn’t hold to much store in the Krend warrantee Like most thing it’s a product warrantee doesn’t cover bad workmanship Ghosting etc Though as pointed out above Krend affiliated is a must Any good contractor will be happy to show off recent jobs that they have completed ball park guide to a fully rendered new build with around 200 mtrs of render (openings measured in) base coat and mesh £8.50 per mtr two coats silicon Krend 15 rubbed up the following day £22 per mtr Labour only Scaffold extra Link to comment Share on other sites More sharing options...
