Thinset for Veneer?

Anyone ever use Thinset instead of mortar for placement of brick veneers and then go back and grout in the mortar for the joints? I’m thinking maybe Thinset might hold the weight of the veneer better on the vertical portions and over the door opening instead of having to use another angle iron. I have two layers of 8mm insulation blankets on a Grande built to spec. Oh and the front door area is already built with fire bricks so the veneers will just cover the fire brick. Thanks!

When I set my veneers I used Liquid Nail / construction adhesive.
The company I bought my brick from said it would work fine and I have had no problems.
Make sure the construction adhesive is rated for outdoor use and I used strips of duct tape and tile spacers to make sure they stayed in place while the glue hardened.
For the grout I used left over stucco that I had on hand and it has held up fine also.
Good luck.

Edit, I glued my veneers onto the base coat of stucco, I am assuming you have the base coat completed.

Thanks for this. Yes I have the two layers of stucco/mortar already applied. I was actually wondering if a glue would be better than Thinset for the long haul. The primary additive in Thinset is concrete and it might adhere better to the stucco mortar layer? Probably either/or scenario will work. Price-wise I think the Thinset would be a lot cheaper than glue. I’ve used glue on a fire pit for retaining wall block and it works great but we also went through a lot of it. Thanks again.

Edit: I have a similar glue product made for brick and stone and everything looks good until you look at the product warning. Wow what a nice brick oven, KaBoom!!!

That does sound ominous, Mark!

In my opinion it would only be a problem if you happen to be baking and setting your veneer at the same time. It’s the carrier solvents in the adhesive that give off flammable vapors. Once the adhesive cures, the solvents will have “gassed off” and the residue (your actual adhesive) becomes inert.

The particular product in the photo can be applied dry or wet, and is expected to perform in outdoor settings. The adhesive itself needs to be soluble in something besides water, which most often means a solvent that has flammable properties.

I agree with your general point:

Yes it would be unfortunate if one were baking and using that glue to set veneers. LOL I used the same glue for a fire pit and never experienced any explosions post drying. and that’s a good thing! Used the Thinset tonight and it worked like a champ. Adhered fast too. Thanks everyone.

And I wish I could say I never knew anyone who might think that was an okay thing to do… :rofl:

Thanks Mark!
