Pebbledash to smooth finish

All,

I am based in South West London and have a terraced house where the front of the house is pebbledashed. I am keen to get the pebbledash to having as smooth a finish as I can and painted to a different colour. I came across two solutions without having to remove the pebbledash:

1) Apply GRC render / Wethertex on top of pebbledash
2) Apply exterior wall coating which will not hide the pebbledash but have been told that it will look a lot better https://www.treatexwallcoatings.com/exterior-wall-coating/

Which is the better option and are there any other choices?

Many thanks for your help
AmberCh

If you are satisfied that your existing rendering is on sound and is clean then there are options.

Talking in Weber product talk then a coat of their rend-aid2 then their OCR will give you a flat render. You could give it a coat of Parex (manufacturer) Microgobetis then their GPR. There are also various high polymer thin coat renders that can be used but I prefer the traditional sand and cement type renders (OCR, GPR).

Incorporate a mesh into the render for crack resistance.

Is the original painted and if it is will rendaid work or only parex parinther?

Always vary cautious about going over existing spar,the thicker the render the more chance of it delaminating, unless it’s roughcasting which is usually baked on.weve a big domestic job to start soon and it’s been overdashed already 3 times.

And you'd trust that over painted dash as in the op's photo?
I'd have thought Parex Parinter might be an option if they won't go with a full removal?

Quite right but I didn’t look at the photo close up, more on what I read. Yes on painted dash then parinter or Fassa K over. Subject to a pull test of course.
