Why do you glue the end joints with white glue?

I also use the Mannington Floor Runner, the silver and blue ones. I own two as a few years ago I was installing alot of Mannington engineered flooring. You MUSTuse the nylon coated staples that are 1 7/8" long with the mannington products, I had a problem once using another brand of staples that they claimed made the floor pop after installation. It took me until I started the installation with the "proper" staples to show them in fact it wasn't the staples- it was the flooring.

From then on I always check what a floor manufacturer either reccomends or states that a particular tool or fastener must be used. I think it's their way of increasing the bottom line in cahoots with a tool manufacturer at the cost of the installer.

Again we get screwed.
