General advice on if / how to re-render

Anonymous user 03/03/2024 - 3.24 PM

I moved into a large detached 1920s house, fully rendered, about a year ago. The render hasn't been painted for a long time. Trying now to make a decision now about the order of doing things including whether to re render or (for now) patch and paint. 1. I have 18 windows in various states of repair, many of which will probably need replacing over a number of years (due to cost), including 3 large bays. There are also 50m of old cracked soffits (not asbestos) that are about a foot deep that will need replacing. If I re render now, is it possible to replace windows / soffits over time without ending up with an awful finish on the render - is it easy to make good and match after doing these kind of jobs? 2. The current render is blown in small patches. If I were to instead get the current render painted, would an exterior decorator expect to patch small bits as part of the job, or would it need a separate job for plasterer to investigate and patch everything before the decorator comes in? 3. I live in an area with lots of oak trees. They stain car paint and window paint so I have to clean regularly. I've read that silicon / krend can be susceptible to this staining and ultimately require painting. Is this true and/or should I consider a different kind of render in this kind of environment? Appreciate this is long question(s) but it's a big house and I'm trying to plan for next 10 years and feel the order of doing things could be very important!

1.My advise would be to sort your windows out first 2.Get advise on the extent of the damage render 3.If blown make plans to have it redone I am not a fan of krend as a good sand and cement render using the right sand will always look better.

I would not use sand and cement render as you can not guarantee it won’t crack again and there is the upkeep of painting there are better products available now, but widows should definitely be your 1st job. Krend is really bad for staining but silicone silicate can be cleaned, in an area like that I wouldn’t recommend any render but if you had to go with one I would say silicone silicate. rendering should be your last job to get done

Like Simmonds Plastering, I would start with sorting the windows out first. Then the Render. 1920’s you are still around period of Lime Renders, soft bricks as the change to cement wasn’t really in full affect until the 30’s. So if you was to get a plasterer / renderer in, look to get a Lime plaster specialist to have a look. They’d look to see what the substrate is and so on. K-rend is said to be breathable but it’s always going to fail on the movement part. And the ‘non maintenance’ part isn’t true. You’ll need to clean it

1.Always attend to the windows first. 2. Inspect the state of render, if blown remove. 3. Replace with Monouche as this needs no maintanince and if done correctly using the full system including mesh cloth there will be no problems with the render blowing or cracking.
