used NP1 and Sel for years, as long as it stick, it will last almost forever. use this to glue tiles where regular thin set will not hold for long, due to vibration and cold weather expansion. for expansion joint( sidewalk and walls), when use correctly, will stop weed from ever growing again between cement floor/sidewall crack( like a permanent round up weed killer), caulk and hold similar and different material together. used on wet location like outside, bathroom, glue toilet to the floor. gap between baseboard/door trim to drywall( cost more than alex caulk, but guarantee not to redo them again(almost forever) patch nail hole on drywall, wood, you name it, it will hold.and the stingky smell are now gone, you should try the old years ago product, it smell for weeks, and too hard to remove from skin.
Pros: Very Adhesive, High Quality of Material, Easy to Apply, Easy Instructions, Good Coverage, Easy to Use, Good Protection
Cons: after application when expose must be painted
