My husband is installing a stone stacked backsplash in the kitchen. It is groutless.

Why would anyone use "mud" when using the pl 400 is so much easier and less messy.
Thanks in advance for your opinions.
Not really sure of the product you refer to as stone stacked. Is it a thin stone veneer product intended to mimic a dry stacked stone?
I have never seen anyone use a construction adhesive for stone veneer application. Besides being unsure of long term holding power, since most such adhesive become brittle and dry with age, the solvents may soak into and discolor the stone. Natural stone is porous and many types are very sensitive to oil or solvent based products under them. By "mud", I'm guessing you mean thinset mortar, the norm for stone and masonry installation. I'd stay with the thinset. If spread on the backer board with the recommended size notched trowel, there should not be a problem with messy visible squeeze out.
Before using anything, check the product manufacturer's recommendations. If not installed with their recommended adhesive, they will not honor the warranty should there be a defect in the materials down the road.
