Question 4

What is 'paint blocking' or 'blocking' in the context of interior walls?

Accepted Answer

Applying a stain-blocking primer over stains before painting

Answer

Blocking refers to applying a stain-blocking primer over water stains, smoke damage, or tannin bleed before painting to prevent them from showing through the finish coat.

Question 5

When spraying a two-part epoxy or polyurethane coating, why is the pot life (working time) important?

Accepted Answer

It limits how long the mixed material remains usable before it begins to gel and cure

Answer

Pot life is the time window after mixing two-part coatings during which the material remains workable — once exceeded, the coating gels and cannot be applied or cleaned from equipment.
