No scratchcoat over board, thinset directly to it for adhered veneer.

I have pounds of EIFS on my clothes, I am convinced that the stuff has some serious lasting power after all the washings its held up through.

.

That is true,but its a contraversial topic...I have seen holes in acrylic from where it was knocked with foot or a soccer ball etc...

but properly done acrylic or sand/cement will give you same effect.

With sand/cement stucco you have to watch more things compared to acrylic.

With acrylic you need proper moisture management. Now that is sometimes PITA to sell to customer...

I could see thinset sticking better to cement board since it seems to use a chemical bond rather than a mechanical bond (I don't really do tile so I'm just guessing here) but for a product like cultured stone, where there is such a rough back, would there be enough surface contact to make a decent bond to the unit?

I have done maybe 6 stones total with thinset(ran out of mortar,didnt wanna drive to vendor,had bag of thin sitting in van) and I gotta say I hate it...thinset has peanut butter consistency,its hard to handle compared to simple mortar...I can see how what Tscar is saying is plausible but I still wouldnt want to do it because of thinset's consistency.

Not to mention that you still getting reg. mortar anyway because you gonna be grouting if you are wet-stacking.

Quit buying cheap ass Home Depot thinset. The good stuff has a 45 minute board life in the heat, is high-build and highly modified, and you even have time to adjust the stone before it grabs.

Who told you I am buying HD thinset?

what about the lack of surface area on the back of cultured stone, eldorado stone etc.. i can def see using it on "realstone system" or any natural stone with a saw cut back but the rough back of culutured stone, there's less against the wall than not

Follow manufacturers installation instructions for the thinset, not the stone, since they warrant the bond.

Interesting. Square notch or V notch?

 

[Tscarborough]

Margin, since they require full coat on the stone, not the board.

What, just glop it on? or a thin smear over everything?

I've used PL many times before for fireplaces, I could climb the wall the next day, but never thinset.

oh, I see. extra steps required and about the same result as a mortar with acrylic additive. That installer has no idea bout masonry, that's obvious.

I think i'll keep staying away from thin veneer except for fireplaces.

actually the stuff was invented to repair masonry buildings damaged in ww2

you dont do any cultured besides fireplaces?how come?

 

[dom-mas]

I do, but i try to price them not to get them. I don't like it and I don't trust it. I don't like that I can't cut it without having to hide the cut. I do fireplaces because they're quick and good indoor winter work or weekend jobs

If you talking about quality of product,then yes I dont trust them.

But I find it to be quick cash...it is great way to do some winter work though I agree...

No, i don't trust mortar to stick product on the wall for a lifetime. To me mortar is a gasket between different surfaces, not to be treated as a glue. That's why I like using PL. But on a bigger job, PL would be very expensive, which was why I was hoping to get excited about that lactite stuff. i've been using bagged parge mix lately and I trust that quite a bit more than regular type N but at $5 a bag and it only covers maybe 10sqft it can get expensive as well. Basically I don't know enough about it, never taught just picked it up kind of, so that makes me nervous. I've been in business about 10 years and haven't had any call backs, I feel like cultured stone would start.

It happens but I would think I would be more worried abot anything else but cultured stone...

I would suggest looking into SPEC-MIX line they have some good products...parge mixing you buy for 5$ a bag is essentially same stuff...I add weld-crete to mix when I lay cultured...that does good trick too..

Do the kind of work you want to do, but if you are going to do it, do it right. Lath over cement board is stupid, as is scratching board. If you are going to stick concrete to concrete board, then do it with a product engineered for that purpose.
