Question 1

On a blueprint legend, what does the abbreviation 'PT' typically indicate for a painting contractor?

Accepted Answer

Paint type

Answer

In blueprint legends relevant to painting, 'PT' commonly stands for paint type, identifying the coating system to be applied.

Question 2

A paint specification calls for a 'shop-applied' primer on structural steel. What does this mean for the field painting contractor?

Accepted Answer

Primer is applied at the fabrication facility before delivery

Answer

Shop-applied primer means the coating is applied at the steel fabricator's facility, so the field contractor typically only applies topcoats unless the spec requires touch-up.

Blueprint cross-hatching on a wall section typically indicates which of the following to a painting contractor?

Accepted Answer

In the project's paint specification section or legend

Answer

Paint system codes are defined in the specification section (often Division 09) or the finish schedule legend, not on floor plans or structural drawings.
