Painting over exterior render

Anonymous user 23/02/2024 - 3.48 PM

Hi, We have a house that was built in 2017, it's covered in a cream-tinted render which is unpainted. The original owners had some patch repairs done on the render, which stand out as a slightly different colour to the original. Overall it doesn't look terrible, but you do notice the patches if you look for them. The patch repairs were done by Linden Homes by means of a warranty claim, who planned to follow up this work by painting the entire house. The painting wasn't done in-time before we bought it, so we inherited the job and the claim. Getting the painting organised has been a 2-year long epic, and now it looks like they can finally schedule it in. After all their incompetence, now we're getting cold feet about giving them so much responsibility, and a job that could damage the appearance of our house if not done properly. A 3rd party, Hometech-UK will be doing the work. My question is first of all, is it really a good idea to paint over bare tinted render? We've been told by those inspecting it, that painting over render is a sort of "upgrade", as it will become washable, less susceptible to dirt and grime, and easier to match the colour with any repairs in the future. We have also noticed the original render colour can be "washed out", as evident beneath where a gutter had been leaking previously. I also asked them whether the bare render needed to be treated with a biocidal wash beforehand (as the paint manufacturer tends to advice), but they said this probably wouldn't be necessary.. Is this a red flag? or reasonable for an only 5-year-old house where the render is in pretty good condition. Any wisdom or advice would be greatly appreciated. A bit more knowledge about how this *should* be done, will make us less susceptible to them cutting corners or doing a poor job. Many thanks!

absolutely fine to paint over the existing. in fact, it's advisable for the reasons you have already mentioned, future colour matching, visibility of repairs, weather proofing etc..just be sure that a good quality exterior masonry paint is used. Most masonry paints tend to be water based but there are some oil based ones such as pliolite etc..are there other houses around yours that are the same design? same rendering ? if so, have a look about at their houses..render, especially on a relatively new build is sometimes prone to cracking due to settlement and in any case, weather conditions. It may therefor be a wise idea to use an elastomer based product which is "stretchy" and will allow movement without tending to crack. Your local paint dealer will be able to advise you on what products are available. good luck. ps. no need for a biocide i shouldnt think on such a relatively new build.
