CDA Surface Preparation & Painting Techniques 2

Question 1

When preparing a slick factory-finished wood surface for decorative painting, which step is most critical before applying a base coat?

Accepted Answer

Sand lightly with 220-grit and wipe with a tack cloth

Answer

Lightly sanding a slick surface scuffs it enough to give the base coat mechanical tooth for adhesion, and the tack cloth removes all dust.

Question 2

Which painting technique involves loading two colors on opposite sides of a flat brush and blending them on the palette before applying to the surface?

Accepted Answer

Double loading

Answer

Double loading places two distinct colors on each side of the brush, creating a gradient that transitions across a single stroke.

Question 3

A decorative artist notices streaky brush marks when applying acrylic base coats to a wooden plaque. The most likely fix is to:

Accepted Answer

Thin the paint slightly with water and use a foam roller or wide flat brush

Answer

Slightly thinned acrylic flows more evenly, and a foam roller or wide flat brush reduces visible brush strokes on flat surfaces.

Question 4

What is the purpose of applying a wash coat (very diluted paint) over a decoratively painted design?

Accepted Answer

To add a translucent tint that unifies colors and creates depth

Answer

A wash coat tones the entire design with a sheer layer of color that ties elements together and can suggest shadow or atmosphere.

Question 5

When painting on a terra cotta pot, why must the pot be sealed inside and out before decorative painting?

Accepted Answer

To prevent moisture from wicking through the porous clay and lifting the paint

Answer

Terra cotta is highly porous; sealing it stops moisture migration that would cause paint to peel or bubble.
