I expect that most of you are well aware of the general subfloor requirements and limitations for all resilient floor coverings. This includes the variations with flatness, expansion gaps, moisture limits—and some will even talk about pH—but to the relief of many at the ASTM F06 committee, I am not going down that road today.
A little while back, I was evaluating a claim for one of our SPC products, in this particular product the locking mechanism used is an “angle-drop-lock”. For those unfamiliar with this, basically the long side joint is first engaged at an angle, then you slide the floor covering to line up the end joint, lower it down, and tap along the high side with a 1 lb. soft faced dead blow hammer or rubber mallet to lock the joint together.
