Painting rough render

Time to paint our recently-rendered external walls. Trouble is the

Persevere with the brush. Masking for spraying also takes a lot of time.

Have you tried one of the small 4" rollers? I find you can get much more force on the smaller area, and get the paint into the surface better.

First coat on fresh render, what paint are you using? When I did this place on partially bare render and very firm old paint I followed the paints instructions for fresh/bare and diluted the first coat with about 5% (10%?) water (Dulux Trade WeatherShield Smooth Masonary Paint). That makes a heck of a difference in how well it gets into the cracks and pores.

Didn't really have much trouble with getting near 100% coverage with a fairly long haired roller.

Well if you want to paint, your garden , your neighbours garden, your car and teh streets cars feel free to spray. B-)

And harry's solar panels.....

In your (wet) dreams!

Standard Sandtex water based masonry paint diluted 10:1.

Our new render is pretty rough.

We don't have any neighbours, but I take your point. The other drawback with sprayers seems to be that they clog up easily unless you are very careful washing them after use. Perhaps the roller isn't so bad after all.

First time I've ever heard the term 'tyrolean'.

The render is what I have always called rough-cast.

Thanks for this and especially for your sheepskin roller suggestion .

Usually a very rough cast finish - often pre-pigmented, that is spattered on by a rotating brush in a tyrolean machine that kind of "flicks" the finish at the wall.

Yep, that sounds like ours, except no pigment.

I had that - its only left on the garage - and actually just go wet with a flappy roller.

Going off at a slight tangent, part of our external walls are covered in crushed shells - sea shells, not egg shells! I think it is a Scottish thing, and I'm sure there is a special name for it, but cannot remember.

Any thoughts on what it is called, and how best to apply paint? The same sheepskin roller?

Thanks,

Yes, I've seen that, in a place called Seahouses in Northumberland.

very waterproof, are seashells.

seashell cladding seems to be the term....
