When installing resilient sheet vinyl flooring over a concrete slab, what condition MOST commonly causes adhesive failure and bubbling?
a.Slab that is too smooth
b.Excessive moisture vapor emission or high pH at the slab surface
c.Room temperature that is slightly cool
d.Using a notched trowel to spread adhesive
Explanation
High moisture vapor emission or elevated surface pH in the slab breaks down flooring adhesive and causes bubbling and bond failure. A smooth slab, a slightly cool room, and using a notched trowel are normal conditions or correct practices, not the primary cause of adhesive failure.
