Rendering Guidance

[Danwild]

Hi,

I am currently renovating a house I have recently bought. I have no DIY experience, I am self tough through the Internet and Books.

I am wanting to render my external backyard wall, which is currently painted in a high gloss paint.

Can I just render over this paint, and if so what mixture should I use, and any special cement. I really don't want to have to strip the paint off.

Does anyone have any pointers on how to start off ect.

Many thanks
Dan

If it is stable you could apply a good coat of Tyrolean or a product called High build available from the merchants to tidy it up some.
If it is perished then it will need to be removed in order for you to start afresh, and without sounding rude it may be something you would want to leave to a pro... plastering /rendering aint easy and its highly likely if it is your first time that you will make a pigs ear of it, no offence intended. If you can decide what needs to be done (tap around the wall if it sounds hollow it has blown and needs removing) and you are determined to give it a shot then by all means post back and I would be happy to advice the procedure.

i think if the paint is well stuck then i would screw on sheets of expanded metal lath. even if the paint is in a bad way i would probably still use eml but take scabbler to the paintwork first.
really the above is all prep, so you could still do it and get a spread just for the rendering

Thanks for the replies.

The paintwork is in great condition, it looks like it's only been painted a year ago. I think I'm going to have a go myself on a small section of wall which is hidden from view.

What mixture of sand and cement should I use, and should I use any aditives?

Thanks again,

Dan
