oh... that one used a polyurethane adheasive PL400.. or locktite PL premuim... my favorte is the adheasive they use for the foam... from wind-lock called foam to foam adheasive... it goes into a foam gun... it says foam to foam... but it will stick anything to anything.. when
i get it on my hands.. there's a cleaner that will take it off.. if done promptly... but if you get a bit on you that drys.. it's a few days of bathing + scrubbing with a rough pumice stone to get it off.. that's how I rate an adheasive.. is how much abrasion it can take in the bath.. before comming away clean.. it's similar to the foam they sell that sprays out of the arerisol cans... but far superior.. and is a polyurethane foam... like the polyurethane in the pl adheasives.... but fills gaps... and is recomended to be used with the stone veneers..

notice ..in all the pictures they are wearing gloves... a smart choice.. although rarely do... and it does come off in a few days...
