Where to buy smooth finishing render mix

[RrogerD]

I'm looking for a bag of pre-mix external finishing render (smooth). Any ideas where I can buy it from any of the usual building suppliers? I've looked online at the usual suspects; Wickes, Travis Perkins, B&Q, Selco etc but cannot seem to find the right thing. They appear to have base coat but not finishing (smooth) coat.
I have a 1980s mock-tutor (white render, black boards) property. I'm removing the horizontal boards but what remains is quite rough, needs smoothing before painting.

Couples off boxes of toupret masonry powder will do It

Presumably, scour the surface and a tacky coat of sbr first?

Will stick fine as is.
About 12 mind in it's used for cracks so you can have a look at it being used.
Just for filling it would work well as you aren't skimming over everything

Ready-mixed cement-based products do not exist, because they can't - cement starts setting the moment water is added, it will even set under water. It doesn't need to dry to set, in fact drying while setting weakens it. So anything pre-mixed would be a brick.

Any pre-mixed cement lookalike products are not cement. They'll be a chalky or plastic-based goo with bits of sand and some grey colour in.

Isn't JetCem cement?

I wasn't after a wet solution, just the correct ratio mix, dry.
I've bought and used the Toupret stuff now. It seems to be working ok (work in progress).

Damp sponge edges to bend in.
You can mix up some and roll over if you want to rough up surface a little.
Get artistic and creative.

What's beneath it? Concrete block? I'm guessing if it's modern then it's not actually panels and the timber isn't actually structural, more likely just nailed on planks.

You may be wasting your time, it's moved before so will move again and crack your patches. You'll probably see the joins and over-skim marks once it's painted.

Probably best to re-do it all, with a modern product in embedded mesh. While you're at it you could consider losing the mock tudor look if you fancy a less fussy finish with less maintenance.

Or just finish one panel, all done your way and painted, see how it looks after a winter.

I'm beginning to despair rather. I started with using the Toupret stuff but it's becoming a massive ball-ache. There seems to be just too much of an area that needs doing. I did try just painting over with Santex smooth to see if the imperfections would show through and they do sadly. Tjis gas had two coats. The painted bit is the better half that I hadn't 'blasted off' with the karcher.
My thoughts: if I used a Santex rough paint, would it hide the imperfections?
Or alternatively, is there such thing as a render skim-coat? If this was an internal wall then a skim over the lot would cover all sins.

Sandtex Trade’s High Build Textured Decorative Coating.
It's like really thick paint and you roll on to give a textured pop pattern.
I can't vouch for how it will look.
No cheap either.

Or you could use.
Teraline (often spelled Tyrolean or teraline render) Teraline (often spelled Tyrolean or teraline render) is a textured, cement-based decorative wall coating applied to interior or exterior surfaces using a specialized flick or spray machine

You’ve got a few options like sandtex textured (easiest but may not cut it), “high build” masonry paints that you roller on with a really thick roller, or a silicone render thin coat which you’d likely scratch finish. In all cases you’d still need to finish filling the actual dents/holes with the filler.

Haha very similar response to Wayners, wrote at same time. Altho I’m talking silicone thin coat rather than tyrolean.

Tyrolean is old I guess.
I was applying that in late 80s as a teenager.
Getting mix consistency correct was the problem as you needed to keep it all the same.
Wind away with gun and it flicked out on wall but looked ok I thought.
I have known people use render and trowel on making a pattern as another option.
Spanish plaster type..
As for skimming so it looks new there are no easy ways.
Patch up and except it or find something that will texture the surface is your only options.

Oh dear, seems I balls-up a bit.
The textured paint 'may' sort it but, we live on the back of a heritage railway with soot blowing across every summer. It gets filty with the smooth paint. I dread to think what it'd be like with the textured.
Thanks for your thoughts and suggestions.
