Materials & Finishes Selection Flashcards

What is the main characteristic of a two-component (2K) epoxy floor coating?

Answer: It cures through a chemical reaction between resin and hardener

Epoxy cures chemically once resin and hardener are mixed, producing a hard, chemical-resistant film.

A decorator notices that the existing paint chalks heavily when rubbed. What should be done before recoating?

Answer: Wash off the chalk and apply a primer suited to chalky surfaces

Chalk prevents adhesion, so it must be cleaned and the surface primed with a binding primer.

What does 'pot life' mean when using a catalyzed coating?

Answer: The usable time after mixing before the product becomes too thick to apply

Once components are mixed, the reaction starts, and pot life is the working window before it gels.

Which finish is typically recommended for kitchen cabinets that need durability and a smooth appearance?

Answer: Waterborne alkyd or urethane-modified enamel in satin or semi-gloss

Hybrid or urethane-modified enamels level well and cure hard, resisting grease and frequent cleaning.

Grasscloth wallcovering is best avoided in which location?

Answer: A steamy bathroom or splash-prone kitchen area

Natural-fiber grasscloth stains with water and is not washable, so wet areas are unsuitable.

Which solvent is used to clean up and thin conventional alkyd (oil-based) paints?

Answer: Mineral spirits

Mineral spirits dissolves alkyd binders, while water is used for latex and alcohol for shellac.

What is a key reason to choose a mildew-resistant paint for a basement or bathroom?

Answer: It contains mildewcides that inhibit fungal growth on the film

Mildewcide additives slow fungal growth in damp environments, though ventilation is still necessary.
