Question 1

What safety precaution is MOST critical when operating an airless sprayer?

Accepted Answer

Never pointing the gun at any body part - high-pressure injection can penetrate skin

Answer

Airless sprayers operate at 1,000-3,500+ psi, which can inject paint through skin, causing serious injury requiring immediate emergency medical treatment.

Question 2

A C-33 contractor needs to strip multiple layers of paint from ornate interior woodwork. Which tool is most appropriate while minimizing damage?

Accepted Answer

Chemical paint stripper with profile scrapers

Answer

Chemical paint strippers soften paint for removal with profile scrapers that follow the contours of ornate woodwork without damaging the underlying profiles.

Question 3

What is the correct procedure for testing spray pattern before beginning production painting with an airless sprayer?

Accepted Answer

Test spray on cardboard or scrap material, adjusting pressure and tip until achieving a uniform fan pattern

Answer

Always test the spray pattern on cardboard or scrap material before painting the actual surface. Adjust pressure until the fan is fully atomized with even distribution.

Question 4

Which type of brush bristle is recommended for applying water-based (latex) paint?

Accepted Answer

Synthetic bristle (nylon or polyester blend)

Answer

Synthetic bristles (nylon, polyester, or blends) are recommended for latex paint because they do not absorb water and lose their shape like natural bristles do.

Question 5

A C-33 contractor is using a power washer for surface preparation before exterior painting. What maximum pressure is recommended for wood siding?

Accepted Answer

1,200-1,500 PSI

Answer

Wood siding should be power washed at 1,200-1,500 PSI maximum to effectively clean without damaging wood fibers.
