Paint

In Plain English

Liquid coating applied to surfaces to protect them and add color.

Definition

Paint is a liquid coating applied to walls, ceilings, trim, and other surfaces to protect and decorate them. Construction-grade paints are classified by sheen level (flat, eggshell, satin, semi-gloss, gloss) and formulation (latex/water-based or alkyd/oil-based). A paint schedule on the drawings or specifications identifies the color, sheen, manufacturer, and number of coats required for each surface.

Why It Matters in Bidding

Painting is takeoff-by-area work, so the estimator measures wall, ceiling, and trim surface and applies coverage rates per coat, making the paint schedule and number of coats decisive for the labor number. Sheen, substrate prep, and primer requirements drive cost as much as the paint itself, and missing accent walls or a higher coat count in the spec is a common way painting subs underbid and lose margin.

Example

Reading the finish schedule, the painting estimator measures 18,000 square feet of wall to receive primer plus two coats of eggshell latex and prices the patch-and-sand prep separately because the spec calls for a Level 4 drywall finish.

Frequently Asked Questions

Estimators take off wall, ceiling, and trim areas from the plans and finish schedule, then apply coverage rates per coat and labor production rates per surface type. Prep, primer, number of coats, sheen, and substrate all adjust the unit cost, with openings deducted or counted depending on the estimating standard used.
Each coat is a separate pass of material and labor, so a two-coat versus three-coat spec changes both significantly. Dark colors over light, or color changes, often need an extra coat or tinted primer. Estimators must price exactly what the spec requires rather than assuming a standard two-coat application.
Prep often costs more than the paint. New drywall needs priming and a finish level that may require additional skim and sanding; previously painted, masonry, or metal surfaces need cleaning, patching, or specialty primers. Estimators line out prep separately so a clean takeoff does not hide significant labor in the unit price.
