So i need to repair some render, i had a new window put in 2 years ago and some render got popped off during the process on the reveal, no big deal it has silicone all over the area for now which i can scrape off. Im looking for the best way to fix this now though, it is slightly textured which i believe i can replicate with clay over the existing render and using it as a texturing piece.
Im looking for what product is best to achieve my goal here? I have some hairline cracks in render elsewhere too so if the product could fill those too with a putty knife that would be great.
I will be finishing it off with some sandtex microseal as the paint on it now is no longer waterproofing it and its 8 years old paint.
Thoughts on product or i can do this with, i did check google and i got alot of companies who do it and afew youtube videos of it being done but i cannot find a "render repair" product other than a bostik one which shows unavailable. Render is from 1970's so i assume it is cement based? (im uk based too)
