Surface Bonding Cement (SBC) instead of Stucco?

We drystacked the base yesterday. It was really pretty easy (we also did the cement and rebar per instructions) and then spread on the quikwall. It did crackle a little bit today, though. Maybe we didn’t keep the blocks wet enough? Are the cracks a structural problem, or just aesthetic? Should we put on another layer of SBC?

Aesthetic. Once your concrete infill cures, you’ve in essence driven concrete pilings down through your wall and tied it solidly to the base at all four corners. The Quikwall holds the blocks in place until the infill cures, and then presents a solid surface for any veneer or paint you will apply. Those superficial cracks will be filled by stucco, mortar, thinset, or whatever else you’ll use to finish the base.

There is a slight chance of weather exposure until you finish it, but I think it’s not worth worrying about.

Nice tint! And if that is going to be your finish (none of the stuff I mentioned above) then for aesthetic reasons you might want to consider a second coat. If you do that, you’ll need to either be exquisitely accurate with matching the first coat tint or plan to do the entire wall again. Here’s where it gets “fun,” because you will need to decide whether the time and materials are worth it to you.

In any case, that wall is tied to the base with rebar and concrete, and it’s going to take your slab, your oven, and the weight of a few pizzas just fine.

Thanks for the reassurance! We definitely have a lot of quikwall left over - it took less than 2 bags. Maybe we’ll consider redoing the whole base when we’re done. And it sounds as if we can use it for the oven too instead of stucco over the lathe (but maybe we should add the acrylic too?). But spreading it on was definitely easy enough. Very glad we did this instead of mortar!

I used the acrylic when I used it over the lathe, and have had no cracks or other issues. The only tricky part we had was tinting the different batches equally. It ended up looking splotchy, and we eventually painted everything.

What color tint did you use there? I have Terra Cotta and buff, but the bottles look identical because the tint is so concentrated. I think I settled on the buff to complement the red clay brick but hard to tell what it will actually look like after mixing and drying.
Thanks

It’s actually the buff, but with quite a lot of color in there! I meant for it to be lighter, but my kid kept emptying the bottle into the bucket.

Awesome thanks! I’ll try and keep the kids away…
