I have a client that is wanting to used flamed granite inside and outside a spa that is currently in cosntruction. Has anyone had experience with flamed granite in a pool or spa? Did it last? Was it slippery? Were there challanges getting it to stay adheared underwater? Cusrious minds need to know!
We just used a flamed granite for coping on a large gunite hot tub. It's beautiful material.
It's not slippery when it's flamed. Polished like a counter top will be slippery.
.If you have to cut the material, use a wet saw. A demo saw or a grinder jumps around. It's very hard stone.
We treat it's setting much like bluestone whereas we make up a paste of Portland and water to a mayonnaise consistency and apply it to the stone and to the bond beam prior to laying down cement. It's a dense stone and it needs a good bond.
We have not set inside a pool or hot tub. We probably would use a waterproofing material such as Hydro-Ban from Laticrete prior to setting stone. They have very specific products for his application. Worth a look on their site or calling tech support.
Thanks Kevin. I appreciate the input.
