Could pre-coat with PVA and let it dry?
More testing needed.

Now I do know that PVA does peel off plasticard unless you really abuse the surface first. I have used the stone DAS clay and I normally put a few blobs of superglue under the clay first.

Not sure what the correct term is but some 'PVA' glue does stick to plastic. 2mm Scale Association sells Easitrac Glue, which is very effective. There must be equivalents elsewhere. Alternative suggestions include gluing tissue paper to the plasticard or maybe even soften the surface of the plasticard with something like Liquid Poly and gently indenting it with something slightly rough. Even fingerprints might do the trick

Ah yes, gluey fingerprints, those I can do.

Tissue paper and liquid styrene cement would work and may well provide the render texture you're after without resorting to fillers for the final finish.
An alternative is to look at artists watercolour or cartridge paper/card which come in various textures and finishes. Such as the ones used for laser cut slates.

I was thinking of an artist's paper of some sort.

A local art shop has “Payperbox” card and paper available. I bought the card for my slate roofs from them, and a just-off-white card for my laser printed Mica van bodies. They do a wide range of card one of which might serve.
That said, I suspect I’d probably try a paint approach.

Hi,
if you decide to go down the paint and talc route may I suggest you apply the talk with a fine, small sieve as used by bakers to coat cakes with a fine layer of icing sugar. It's easy to ensure an even coat and any excess can be easily removed for reuse.

Hi Chris I am finally feeling good enough to make a rational comment after a long week of absolute exhaustion due to getting Covid last Tuesday. The use of art paper or card cover stock glued to the styrene would probably be a good candidate for the rendering. Perhaps use some gesso as an undercoat.

I'm in Birmingham today so will be having a look in the art shop to see what's available.

Render...
This does work for smaller scale "tarmac" or asphalt type surfaces, at least in small areas.
Wet and Dry type paper, but sanded down with the same thing.
It removes the uniformity and some of the textural highpoints; but not to the same degree as using used paper would do.....

Thankfully in this case, the end wall has no brick surrounds to the windows. It does have some external raised casing... Easier to hide paper ends.
I'm not replicating the fancy double doorway as my end gable doesn't abut a busy shopping street.

For your render, here's another possible option.
I've used it as ground cover in a yard (in 4mm), but it could work as 7mm scale render. There is a finer version too. Hard to get a sense of the texture in photos.
Spreads on in much the same way that you apply a full size render finish. Seems to adhere very well to card and plastic, remains reasonably flexible when dry (which takes a couple of hours). Downside: not cheap, this 237ml pot was £15, but would cover a lot.
