We have just had the house re-roofed. To complement it we figure that it would be nice to improve the appearance of the walls. We cannot justify the cost of re-rendering so are looking into painting the horrid roughcast pebbledash stuff.

So, I figure that we have a couple of options.

1 Pay someone to do it. I figure that this is the easiest and most expensive option that will also probably give the best results.

2 DIY, either with a brush/ roller or with a sprayer. With a brush/ roller it will kill my arms but will definitely? be the cheapest option. I've loads of painting and decorating experience, even did it for a living for a short time. But never on roughcast. Yuk.

I could hire a compressor/ spray gun if I knew the specs required. Or similarly I could buy one and thus have more man-tools for future use, 'cos you never know when you might need one. I've seen compressors on-line for £120, sprayguns seem cheap enough too.

It's a three bed detached house in sunny Carmarthenshire.

I stippled (brush) ours, front and back of our small terraced cottage. Made me want to kill indiscriminately. Seek other options.

Spray. Get a pro to do it (I did mine, they will be much quicker/better)

You want an airless spraying system for that type of application.
Also, spraying outdoors can be a nightmare if your neighbours cars are within 50m or so.

Big roller will be fine.

Unless it's painted now then don't. It will start the forever painting cycle. It will need doing again in five years and will lower the value of the house. It will always be the wrong colour and you will never get it back to being unpainted unless you take the lot off and re-render.

Dont do it its not as simple as it sounds.
you must use a really high quality paint or it will fall off like dandruff you will have to pressure wash and treat the mold or it will be back like arnie even if you cant see it its there and its bloody hard work.

oh and remove all gutters and drain pipes and cables or you will have paint on them too
and it will look crap.

Don't tell me that. I have a half painted house (!?) that note needs doing this year, as well as a couple of patched spots...

I doubt it. My wife and I painted the pebbledashed front of our beach hut last year - took us 3hrs to paint approx 4sqm.

Render it or forget it.

Loads to think about here folks, many thanks. The membrane, felt and battens are done. The lead too and most of the slates. It is looking fantastic. Ridges yet to be done, likewise the guttering.

Once the scaffolding is down I'll reconsider painting. The black streaks on the dashing will fade surely once there is less water pouring down the walls instead of being intercepted by the gutters.

We too faced the painting dilemma but had the house clad with solid wall insulation, then rendered with coloured render.
It's transformed the house from a comfort point of view.
Just s thought if it's a solid wall property. To pay a firm to paint it might be half the cost of insulating it.

Whatever you do, dont try it with a brush. Utterly mangled both my wrists and got virtually no-where trying to do parents garage.
Dad told me what man-child i was and he'd do it himself. Oh the smugness i felt an hour later when he too had mangled wrists, also hadn't made much progress, and had half destroyed the brush for good measure 😆

Give it a good wash and then see what it looks like ,you have to wash it to paint it any way.

Render

Ah well, I mustn't have painted the pebble dashed back of the house last year with a 12" deep pile roller, my mistake.

If you want a real pain in the balls try roller painting [u]new[/u] pebbledash.
The in-laws got me to do about 60m² that they'd had re-rendered last year.
I power washed it thoroughly beforehand to remove any loose gravel and still came away looking like I'd been used for target practice by every seagull in the universe!
Every stroke of the roller flicked a handful (literally) of freshly coated gravel [b]EVERYWHERE[/b]
When you add in that you have to thin the paint to fill all the wee holes, give it three coats and still have it look crap I can only say NEVER EVER AGAIN!!!

Massive floppy haired roller and some decent paint. Ladder is also handy

decent paint

Absolutely this too, use a trade centre, I use Johnstone/Leyland locally, the trade stuff is night and day compared to B&Q etc.

Our neighbour who's a decorator did ours last summer. Came up looking ace. For the bare portions he coated it with a clear coat of something first - can't remember what it was. He then did two coats and it tranformed it. He stiple brushed it all by hand. He would never do roller/spray application as he was worried about neighbours cars.

I did the whole outside of our house 3 years ago. By myself. It was bloody hard work but it looks way better now and am still pleased with the results. 3 years later it is showing no signs of discolouration or any flaking, staining etc.

My tops tips would be:
-Don't bother washing, I found it to be unnecessary.
- Do give it a thorough brushing witha stiff brush to remove loose pebbles and dirt.
- Do use stablising solution first e.g. http://www.wickes.co.uk/Wickes-Exterior-Masonry-Stabilising-Solution-1L/p/214144?CAWELAID=120135120000006501&CAGPSPN=pla&CAAGID=37524966292&CATCI=pla-72073524379&gclid=CJvV4-zT-9ICFUgW0wodWD8KeQ&gclsrc=aw.ds
it makes the paint go on sooooo much easier.
- I had no luck with a roller, just by a few decent brushes and accept you are going to trash them with aggressive stippling.
- Use a quality paint. I got a good deal on Sandtex and it's still looking good 3 years on.
- It's going to take a while and will knacker you out!

You're forgiven 😉

Maybe it depends on the type of pebbledash - plus I can see that the more coats of paint there are the easier it would get. But a roller??
