• DInstalling roofing membranes and applying below-grade waterproofing as a standalone trade

Per 18VAC50-22-30, which surfaces may a PTC contractor coat or cover?

• ABoth interior and exterior surfaces
• BInterior surfaces only; exterior work requires the ROC specialty
• CExterior siding only; interiors require the HIC specialty
• DOnly new construction; existing buildings require a CIC specialty

Which preparatory operations does 18VAC50-22-30 include inside the PTC specialty?

• AInstalling floor joists and subfloor so a room can be painted later
• BSurface preparation, caulking, sanding, and cleaning preparatory to painting or coverings
• CRunning new branch circuits to power spray equipment

• BROC and DRY only
• CLAC and ASB only
• DCBC and RBC classifications and the HIC and CIC specialties

A Richmond homeowner wants vinyl wallcovering in a hallway and ceramic tile on the adjacent bathroom walls. What may a PTC-only contractor perform?

• ABoth the vinyl wallcovering and the ceramic tile, because both are wall finishes
• BThe vinyl wallcovering only; ceramic tile is outside PTC
• CThe ceramic tile only; vinyl wallcovering requires the FLR specialty
• DNeither finish; wall work on dwellings requires an RBC classification

A client asks a PTC contractor to permanently remove lead-containing paint as a lead-abatement project. How does 18VAC50-22-30 treat that work?

• AIt is the LAC specialty; no other classification or specialty, including PTC, provides le…
• BIt is ordinary PTC surface preparation whenever the building is older than 1978
• CIt is included in PTC if the contractor also sands and primes after removal
• DIt is included in HIC only, so a PTC firm may subcontract it without any lead credential

A PTC-only contractor is asked to hang gypsum wallboard, tape the joints, and then prime and paint the new walls. Which portion is inside PTC?

• AHanging the board and installing sheet-metal studs
• BTaping and finishing the joints only
• CPriming and painting the finished drywall; hanging and taping are DRY work

• AThe shingles are incidental caulking, so they stay inside PTC
• BReplacing roofing materials that form a weather-resistant roof surface is ROC work, not P…
• CAny exterior coating-related leak repair is automatically PTC
• DPTC may replace shingles if the area is smaller than one square

During an interior repaint, the owner wants new dedicated receptacles installed for future HVLP spray equipment. May a PTC-only contractor perform that electrical work?

• AYes, because the receptacles serve painting equipment
• BYes, if the circuits operate at 50 volts or less
• CYes, if a licensed electrician later inspects the connections
• DNo. Installing new branch-circuit wiring is outside the PTC specialty

A developer wants one contractor to build a new single-family dwelling, including framing, and then paint it. What does a PTC-only license authorize on that project?

• AThe painting and wallcovering portion only, not construction of the dwelling
• BThe entire dwelling, because paint is part of new residential construction
• CFraming and paint, but not plumbing or electrical
• DOnly the exterior paint; interiors require a separate HIC specialty on new houses

Why must grease, dirt, and chalk be removed before a new coat of paint is applied?

• ACleaning raises the gloss so fewer finish coats are needed
• BResidue is required as a bonding layer for latex
• CContaminants block adhesion and cause peeling, cratering, or telegraphing through the new…
• DCleaning is only a cosmetic step and does not affect film performance

An interior door has a hard, glossy alkyd enamel. What is the correct preparation before recoating it with a modern waterborne enamel?

• DDry-remove the efflorescence, correct the moisture source, and then prime with a masonry…

An older exterior acrylic has chalked so that a hand wipe leaves white powder. What is the correct prep before recoating?

• AApply a high-gloss alkyd directly to lock the chalk in place

• CLAC applies only outdoors; RRP applies only to metal primers
• DA PTC contractor may advertise abatement if an RRP firm certificate is posted in the shop

When lead-safe work practices are required on a housing repaint, which approach is consistent with those practices?
