Hi,

I'm looking for some advice on rendering.

Having moved into a property last September, I knew the property needed the wall ties replaced and I am carrying out the work this spring. As scaffolding will be up, i've investigated getting the house re-rendered because its quite patchy in places where areas have been patched up very poorly and no effort made to blend the original rough finish with the new smooth. The render sounds solid (not hollow) so i'm not concerned it will break away, but i've looked into hacking it all off and starting again but unfortunately our budget won't allow us to do that this year.

Seeming as scaffolding will be up, I wondered if anyone has any ideas how I could turn the 'new smooth' render rough to match the 'old render' to at least make it not as obvious before its repainted.

Could I potentially use a sandblaster or some sort of blasting method?

Obviously I don't expect to make it perfect, but if anyone has any ideas which may at least tidy up the render I would really appreciate it.

I've attached a few photos which may or may not help.

Thanks,

Tom

It may help to get an answer if you would list your location.I've been doing construction in the US for 45 years and am not familiar with some of your terminology.

Hi mako1,

Sorry, i'm actually in the UK.

Which terminology are you unsure on?

The house is rendered and has a rough textured finish, but in areas someone has recently rendered over and left a smooth finish. (Image 1 shows an example of the difference between smooth render and rough textured render)

I'm looking for advice on turning the smooth render so that it looks more like the rough textured render. I currently can't afford to remove all the render and start again so i'm interested if anyone has any ideas which could potentially be a quick fix for a couple of years so the difference between the smooth and rough render isn't as obvious.

Thanks.

I would guess it's the UK, so you will find it difficult.
Render is stucco.

In the US, to render is to convert a pig into tallow. Has other meanings as well, but I have never heard stucco called render. Kind of like the boot of a car, two nations divided by a common language.

There are some textured masonry paints that can be used with a honeycomb roller.
You could also go over it with a Tyrolean gun.

Thanks for confirming Wildo1: I'm not real familiar with what is available in the UK. Always wanted to visitand still hoping to.
To answer your question:Find some fine sand (masonry sand) and some Portland cement .Mix them together with water to get the consistency you need and spread it on with a flat trowel.
You'll have to play around with the mix and the trowel to get the correct pattern and graining as everybody has their own way of doing it. 100 guys will give you 100 answers but this is basically what you have.
