Question 1: What is the primary purpose of a primer coat before painting?
- To add the final color
- To improve adhesion and seal the surface (Correct answer)
- To create decorative texture
- To protect from UV rays
Correct answer: To improve adhesion and seal the surface
Primer improves paint adhesion and seals porous surfaces, ensuring better coverage and durability of the topcoats applied over it.
Question 2: What paint sheen is best suited for high-moisture areas such as bathrooms?
- Flat latex
- Semi-gloss or gloss (Correct answer)
- Matte
- Chalk paint
Correct answer: Semi-gloss or gloss
Semi-gloss or gloss paints are recommended for bathrooms because their hard surface resists moisture and is easier to clean.
Question 3: What unit is a mil when used to describe paint application?
- Millions of square feet of coverage
- One-thousandth of an inch (Correct answer)
- Type of roller cover
- Minimum illumination level
Correct answer: One-thousandth of an inch
A mil equals one-thousandth of an inch and is used by painters to measure wet and dry film thickness of applied coatings.
Question 4: What technique minimizes lap marks when rolling paint on a wall?
- Roll in random overlapping directions
- Roll in one consistent direction while maintaining a wet edge (Correct answer)
- Apply very thick coats
- Always roll from bottom to top only
Correct answer: Roll in one consistent direction while maintaining a wet edge
Maintaining a wet edge by rolling in one consistent direction prevents lap lines that appear when a partially dried edge is re-rolled.
Question 5: What is the minimum temperature for applying latex paint outdoors?
- 32 degrees F
- 40 degrees F
- 50 degrees F (Correct answer)
- 60 degrees F
Correct answer: 50 degrees F
Latex paint should not be applied below 50 degrees F because cold temperatures prevent proper film formation and curing.

- 3/4 inch
- 1 inch
- 1/4 inch (Correct answer)
- 1/2 inch
Correct answer: 1/4 inch
A 1/4 inch nap roller is used for smooth surfaces like cabinets and doors to minimize texture and achieve a smooth finish.
