    Hi - I have a rendered wall that was re-rendered 18 months ago. I like the colour of the render - white cement was used- and I just want to apply the correct thing to protect the render from the rain and frost. I DON’T want to change the colour with paint. I can only find advice on painting. Should I apply something like Thompson’s Water Sealant, or should I not apply anything at all. There are no damp
    issues with the wall at all, and never have been, I simply had the render redone as it had blown in places, loads of cracks and moss.

    or do I HAVE to apply something like Dulux weathershield to protect the wall but find a colour that is like sand and white cement colour?

    thanks

    you shouldn’t need to put anything on it.
    thompsons is the last thing i’d use.

    is this a house wall? it shouldn’t have any cracks ,being relatively new. and given that information i’d paint it with something. sandtex is my personal preference.

    Yes, it’s just a short stretch, about 25 ft say, single storey on one south facing wall. Wasn’t sunny hot when done, so not in direct sun when drying out.
