Use these study tools to review construction painting concepts, prepare for supervised practice and organize project information. These are learning aids—not a substitute for training, specifications or safety procedures.
Quick glossary
- Adhesion: the ability of a coating to remain attached to a surface.
- Binder: the film-forming ingredient that holds coating components together.
- Chalking: a powdery surface caused by degradation of a coating binder.
- Efflorescence: soluble salts deposited on masonry as moisture moves through it.
- Holiday: a missed or discontinuous area in a coating film.
- Pot life: usable time after multi-component products are mixed.
- Substrate: the surface receiving the coating.
- VOC: volatile organic compound.
Pre-job planning worksheet

- Substrate type and existing coating condition:
- Known moisture, corrosion or contamination issues:
- Potential lead or other hazardous-material concerns:
- Specified primer and finish products:
- Required surface preparation and film thickness:
- Environmental limits and access equipment:
- Protection, ventilation, PPE and waste controls:

Knowledge check
- Why should a painter identify the substrate before selecting a primer?
- What is the difference between wet-film and dry-film thickness?
- Why must moisture problems be corrected before coating?
- Where should a student look for recoat time and application temperature limits?
- What should be checked before disturbing paint in an older building?
- Why can VOC limits differ by coating category and local air district?
Suggested answers
- Different substrates and conditions need different preparation and compatible primer systems.
- Wet-film thickness is measured during application; dry-film thickness is the resulting thickness after drying or curing.
- Trapped or recurring moisture can cause adhesion failure, blistering and substrate damage.
- Consult the manufacturer’s current technical data sheet.
- Assess building age, potential lead hazards and applicable lead-safe rules before sanding, scraping or other disturbance.
- Rules are established for product categories and jurisdictions with different air-quality requirements.
