Do I need to remove all render before rerendering with render

Best Answer

"Yes you must remove old render before rendering with k render or monocouche render I hope this helps"

"Best advised to remove existing render before a re render, due to not knowing the strength of the current render and new render needs to be applied on a stable substrate, hope this helps"

"Unfortunately you do need to remove old render. I hope this is a help."

"Yes remove all render so that suction levels are equal and brickwork is sealed to prevent cracks"

"Yes all render needs to be removed, and then re applied with base coat and reinforcing mesh"

"Hi there
It depends on what type of product you are using
Sand and cement or through colour as there are different methods
If the render is solid as not blown off the wall in places
With sand and cement it can be wire-meshed over and re-done
With through coloured render we can base coat and fiber mesh so it leaves a solid base then new beads can be applied and a top coat applied that can be up to a choice of 50 colours meaning no painting after less time paying for scaffold to be up and can be finished much quicker then traditional method as we can machine apply
Hope this helps"

"All depends if the old render is stable enough to put your bonding of R10 render aid on top which will then allow you to put your base coat and kay render on top of that."

"Yes most definitely you need to remove before krend if you go over the old stuff with fresh the old stuff would come off and crack."

"Only if the old render is loose and has no key for the base coat to apply to."

"There is a lot of products on the market now that you don’t have to take all the render off but the bottom line You’re only going over the top of rubbish which will make the top coat fall off .These products are not tried and tested I can almost guarantee you they won’t work in the long run."
