Hi,
I'm trying to get an advice what is the best approach to replacing old render plinth & external wall render after damp proofing (this is old house btw), there seems to be a lot of opinions of render bridging the DPC etc.
The way I understand it so far on the brick only wall it's quite straight forward, you put DPC layer around 15cm above ground level and plinth is underneath that - should not bridge DPC.
But what do you do on the wall where bricks are covered with render? Is it correct to put plinth render to the level of DPC then install Bellcast Bead on top of that and put wall rendering on from the DPC lever and above? (Pretty much what is done on this youtube video or is there a better way?
Also the DPC level should be 15cm above the external ground level and below the internal wood floor as seen on this youtube video
which is pretty much impossible as the wood floor is on the same level as outside ground - any advice here? Is it better to put the DPC lower and cover with plinth or keep it at 15cm and install something (damp proof membrane?) inside up to the level of DPC? Or have second internal DPC level lower just above floor?
Lastly after removing old plaster inside is it enough to put a new one with render additive (Renderguard Gold) or is it better to treat the wall with some kinds of Cream (Dryshield Cream) before rendering?
If you can point me to any information online I would be grateful as I couldn't find much apart from couple you tube videos.
Thanks
