Silicone or Acrylic Render ?

horsey63

Hopefully this is the right forum. We're getting ready to do an extension next year and also to insulate the house and are planning on doing external wrap with render, now here's the question (while we wait for prices), what are peoples thoughts on using Acrylic versus Silicone render ?


The logic seems to be that Acrylic is sufficient for the 'normal' domestic house (which ours would be), however, 3 houses in our estate have done it over the last 5 years and already they are looked quite 'tired', one I spoke to has taken a power hose to it with little effect. Some say you can paint it but my bit of googling suggests that its very easy to damage it as in when you would put a ladder against it. So thats when we came across Silicone render and wonder what people's thoughts are ?
TIA

I'm not familiar with silicone render, but my other experience with silicone suggests you will never be able to paint it.

Last thing you want to do with acrylic render is take a power hose to it. (perhaps that's a mistake ppl have made in your estate)
I've had it done about 3 years now and it still looks in good nick.
Had an issue where a guy (i had in doing some work in the front garden) power hosed a section of the front wall of the house (thinking he was doing me a favor) and it stripped the colour off. Tired is how i would have described the look.
I was getting the boundary walls done recently and got the guy to go over the damaged bit.

ps: ive no experience of silicone render so cant help with the comparisson.

The guy who had power hosed his acrylic render with little effect, thinks that a mild solution of bleach in the power hose is the next step yikes !!

Some good cleaning advice here:

Based on this (and no real world experience) silicone seems like a better fit to our climate.

Did you get any quotes on this? I'm looking at getting a spray render on two block boundary walls in the back garden of a new build in Castleknock. It's probably 50 sq metres in total.

Nope, not yet ! initial plan went to QS and way way over budget for the extension, so we're back to the drawing board, we'll probably have another go with QS in a month or so.
