Can stucco be placed directly on Hardibacker board ?
Building a barbecue island and using Hardibacker board. I know this will take Thin Set but am not sure if Stucco can adhere directly to it. No one will give me a direct answer. Hardibacker board company says to consult the stucco manufacutuer.
I don't want to hassle with a metal mesh if I don't have to. My assumption is if I use concrete adhesive and then stucco, it should be fine but want answers from people that know or have done this.
I plan to scratch, brown and texture coat. Also the Hardibacker board is attached to steel studs. I plan to tile the top which of course I will be using thin set but plan to stucco the sides.
As for the heat of the barbecue, I don't think that will be a problem since I see this method of contsruction on commerically sold barbecues.
As for the adhesive there are commerical adhesive that you apply on concrete which helps adheres aditional concrete or stucco. I was thinking of this since hardibacker board is made of cement.
