What actually damages a floor finish?
Not the rug. The pad. Latex and rubber backings degrade against urethane and oil finishes, and a pad that has gone hard or tacky leaves a haze, a yellow cast, or a pattern imprint that only refinishing removes.
The failure is slow, which is why it usually surfaces long after the project closes and lands on whoever touched the floor last.
What belongs in the specification?
Four elements, each of which closes a substitution path:
- Material: 100% post-recycled felted fiber, latex-rubber free
- Thickness: 1/4 inch standard, 1/8 inch at door clearances and radiant heat
- Dimension: cut to the finished rug size, not a stock size
- Supplier: named, so "rug pad by others" cannot be value-engineered
How do you explain it to a client?
The pad is the only product in the room touching the finished floor twenty-four hours a day. Clients accept floor protection as a reason far faster than they accept a discussion of pad density.
