Punjab PSEB Sr. Sec. NSQF Construction (Painter & Decorator) study plan

List at least eight painting-specific hazards (solvent vapour in a closed room, lead dust from old paint, paint mist from spray, fall from ladder or scaffold, electric shock when painting around fittings, dermatitis from thinners, blocked escape route, empty solvent drums near flame) and match each to a control in the hierarchy of control.

Extract from a sample safety data sheet the flash point, VOC content, storage class, required PPE, spill action and first-aid measures, and place them on one sheet.

Select the right respiratory protection for three tasks (solvent-based gloss with A1P1 or A2P2, dry sanding of putty with P2/P3, two-pack or isocyanate-containing product needing an air-fed system) and demonstrate a user seal check on each.

Demonstrate brush loading and lay-off on a practice panel with a 75 mm cutting-in brush and a 100 mm flat brush, then the same with a medium-pile roller, keeping drips to zero and roping to under three visible lines.

Set out a site safety routine for a one-room repaint: isolate and re-energise the circuit, ventilate, barricade the wet area, and hold a two-minute toolbox talk in your own words.

Measure and record moisture content (target 12% or below for masonry/plaster) and surface pH (target below 9–10 for emulsion over new plaster) on three differencing substrates, and give a written go/no-go verdict for each.

Sequence a full preparation routine on three surfaces - dust off, degrease, scrape, patch, abrade through graded paper (80 to 120 to 180 grit), dust off - and justify each step.

Strip loose and blistered paint with a scraper and heat gun, feather the edges, and state when a lead test is required before sanding paint on older joinery.

Treat four recurring defects: efflorescence on new brickwork (dry brush, wash, alkali-resisting primer), knots in softwood (knotting or shellac), rust on steel (wire brush to bright metal, zinc phosphate or red oxide primer), and hairline cracks (open to a V, fill, tape if movement is expected).

Demonstrate correct filling of dents and nail holes with putty or filler in two passes, sanding flush without dishing the surrounding surface.

Classify ten products by binder, thinner, suitable substrate, recoat interval and typical coverage - alkali-resisting primer, wood primer, zinc phosphate/red oxide metal primer, cement paint, acrylic emulsion, alkyd gloss enamel, distemper, wall putty, texture material and a sealer.

Mix wall putty to a workable consistency, apply two coats at roughly 1–1.5 mm each, and sand between coats to a smooth, pinhole-free surface.

Calculate the thinner required and the recoat window for three products using label data, and record what happens if the recoat window is missed on an alkyd system.

Draw the standard coating build-up for interior plaster (primer plus two finish coats) and for exterior masonry (four coats including alkali-resisting primer) and state target dry film thickness for each.

Distinguish primers from sealers from undercoats, and explain when a mist coat is used on new plaster or skim.

Cut in a 3 m ceiling-to-wall junction freehand, achieving a line within about 2 mm without masking tape, and repeat at a door frame and a window reveal.

Apply the same coating by brush, by medium-pile roller and by spray on three identical panels, then compare film uniformity, overspray, edge definition and time taken.

Measure wet film thickness with a comb gauge, calculate dry film thickness from volume solids (DFT = WFT × volume solids %), and check the specified DFT is reached.

Diagnose six defects from written descriptions - sagging, orange peel, blistering, holidays or misses, fat edges, brush marks - and prescribe cause plus remedy for each.

Plan coat intervals and drying conditions for a full room sequence (ceiling, walls, woodwork, doors) so that you never re-enter a wet coat, including ventilation and temperature limits.

Match access equipment to four given jobs - single-storey exterior, stairwell ceiling, 4 m high hall and a shopfront fascia - and state the load limit and inspection requirement for each.

Set a ladder at the correct 1-in-4 angle, foot it or tie it at the base, secure the top, extend it about 1.05 m above the landing point, and demonstrate the three-point contact rule.

Inspect an erected scaffold against a ten-point checklist: base plates, standards, ledgers, transoms, lift height around 2 m, guardrail height, toe boards, platform width, ties to the structure, and a current inspection tag.

Handle and store materials safely: stack cement bags off the floor, keep solvents in a locked ventilated store away from ignition, earth or bond drums when decanting, and dispose of empty containers correctly.

Clean and store tools after use - brushes washed in the thinner matching the binder, rollers combed and dried upright, spray gun flushed and nozzle soaked - and record the cost of poor tool care.

Produce three decorative effects on sample panels: knife-applied texture, a stencilled motif with correct registration, and either ragging, sponging or colour washing over a base coat.

Hang a wall covering on a sample board: size the wall, cut with the pattern repeat added, apply the correct adhesive, allow the specified soaking time, book-fold, match the pattern, and smooth out air bubbles.

Lay out the tool and glaze sequence for wood grain and for a marble effect, naming the base coat, glaze, dragging or veining tool, and the protective top coat.

Calculate texture material for 100 m² from the supplier's consumption figure, adding 8% wastage, and cost the decorative scheme alongside a plain emulsion alternative.

Measure a room with a tape and rule, deduct openings correctly, and compute paintable area for walls, ceiling, doors and windows separately.

Prepare a take-off and cost sheet using litres = (area × number of coats) ÷ spreading rate, plus 5–10% wastage, a labour constant per m², overheads, profit margin and applicable tax.

Write a client quotation for a two-room job with scope, exclusions, brand and sheen of the proposed system, payment terms, timeline and validity, and defend the price in a two-minute explanation.

Draft a one-page CV and portfolio entry listing six competencies (surface preparation, putty and sanding, brush/roller/spray application, texture work, estimation, safety) and two project descriptions.

Role-play a client conversation: present three finish options at different price points, then handle a complaint about patchy sheen using a five-step script - listen, inspect, explain, remedy, confirm.

Execute one complete small project end to end - inspect, prepare, prime, putty, sand, undercoat, finish, snag, clean and hand over - recording the time and material used at each stage.

Inspect a finished surface under raking light against a ten-point snag list and rectify three deliberately induced defects (a sag, a holiday, a sanding scratch) with the correct remedy.

Complete two full-length timed mock tests across all nine domains, score at least 75% in each, and write a correction note for every wrong answer.

Explain the inspection and handover procedure to a client in writing, including a maintenance note on washing, recoating interval and touch-up storage.
