These 10 free RFI questions are organized by exam domain, so you can see how each part of the Resilient Flooring Inspector (RFI) blueprint is tested. Reveal the answer and explanation under each question.
A contractor rejects a submitted homogeneous sheet-vinyl product because its data sheet lists a factory-applied polyurethane surface treatment. The construction description shows uniform composition and pattern throughout the vinyl body, with no printed film or separate backing. How should the inspector evaluate this objection?
Correct answer: D - Retain the homogeneous classification; the factory surface treatment does not contradict it.
An invoice identifies a resilient sheet product as vinyl. Which entry in the manufacturer's material declaration would most clearly contradict that identification?
Correct answer: D - An oxidized linseed-oil and rosin binder formed onto a jute backing.
Which ingredient most directly allows a PVC flooring compound to be formulated as flexible sheet rather than a rigid material?
Correct answer: B - Plasticizer
An authorized examination of a detached glue-down plank shows adhesive still bonded to both the plank backing and the prepared slab. The fracture runs through the adhesive itself; the patch and the plank's manufactured layers remain intact. Which failure-plane description belongs in the report?
Correct answer: C - Cohesive failure within the adhesive layer.
New blue-gray Marmoleum has a yellow cast where opaque floor protection was left in place. Approved routine cleaning does not change the color, but an uncovered test area begins to lose its yellow cast under ordinary room lighting. The surface is intact. Which response best fits these findings?
Correct answer: C - Allow light exposure and reassess the color before corrective treatment.
Hospital bed casters repeatedly cross vinyl-flooring joints, and several joints have loosened. Uninstalled material met the project's ASTM F970 residual-indentation requirement. The supplier argues that this result rules out a flooring-system contribution. Which additional evaluation would most directly address the service condition involved?
Correct answer: A - Rolling-load testing of the actual flooring, adhesive, and underlayment assembly.
A concrete RH test plan specifies 1.2-inch-deep holes in a uniform, 6.0-inch-thick suspended slab. Nonperforated steel forms remain against the entire underside, so only the top face is available for drying. Applying ASTM F2170's depth requirement, what revision is needed?
Correct answer: A - Use 2.4-inch-deep holes to account for one-sided drying.
Submittals for a glue-down LVT assembly permit concrete RH up to 95% for the flooring, 90% for the adhesive, and 85% for the patching compound. Valid in-situ tests read 88% RH. No moisture-mitigation system or written exception is specified. The contractor proposes proceeding because both the flooring and adhesive limits are met. What should the inspection record state?
Correct answer: B - The patch's moisture limit is exceeded, so the specified assembly is not acceptable.
During dry layout of a new Marmoleum sheet, a broad transverse rise appears near the middle of the roll. There is no crease or backing damage. The supplier identifies a stove-bar mark from the bottom of a loop used during manufacturing. Which treatment follows Forbo's installation guidance?
Correct answer: A - Massage the rise into wet adhesive and roll it first, maintaining full contact.
At a U.S. renovation, a crew is preparing to grind old resilient flooring and its adhesive. The owner produces a negative asbestos report for the tile, but the report expressly excludes the backing and mastic. Neither excluded material has been evaluated. The crew has a shrouded grinder and HEPA dust collection. What must happen before the proposed grinding can proceed?
Correct answer: D - Hold the grinding pending a qualified assessment of the backing and mastic.
