Plastering an external wall

[Barney Crow]

Good afternoon everyone.

I'm hoping to find some help....if possible!

So I decided to plaster/render/stucco/cement a wall behind the house. It's 60ft by 3ft.

I want it to look like the photos attached. After many discussions i've been told every which way to get it done and none have had the result I wanted.

I was told cement. Then stucco. Then back to cement. The last guy said acrylic cement which is last on the list of everything else that we've tried.

My gut is that it is a cement finish because it's silky smooth. The Stucco was rough because it has stones in.

Problem is it's 90 degree weather everyday and the cement sets soooo quick.

Is there a specific brand of cement that will end up working? we got the cement on but had zero time to smooth it out etc.

Any help would be really great.

here's some links to examples

This is a UK site not a USA site.

Your pics show modern stucco thats probably been blown on - the prepared mix is delivered to the site.
Some Synthetic stuccos can be smooth finished - so can traditional sand & cement mixes.
What you are attempting in high temperatures is risky for a DIY'er.

Are you applying to a framed or a masonry background?
Is this a retaining or a boundary wall?
Was any kind of "metal mesh" used?

I have no experience with the materials you use, but in Southern France, for example, roadbuilders always pour concrete in the afternoon so it will not be exposed to the midday sun until it has had time to start curing.

in your position I would also use a fine water spray to wet and cool the wall before starting work, and to mist the new material during and after application. Wait until the sun has passed overhead and will not shine on your wall. When finished, hang plastic sheet over it to delay drying.

Cement products have negligible strength and hardness if they are not kept damp while curing.
