I need to install my bathroom granite back splash and side splash and was
wondering what the best method would be to install it. Should I just use
PL400 adhesive? I am thinking I shouldn't in case I need to take the granite
counter top off some day. I am not sure what adhesive to use. I was thinking
I may be able to get away with some silicone on the back and bottom of the
back and side splash. Not sure.

Also should I seal the back of these before I put them on? I am thinking
just the front will need to be sealed. While I am at it, what type of sealer
should I pick up? I have grout sealer, but not sure if this is what I should
also use. I am told I need to seal the granite counter top once every year.

Thanks for your help.
