Planning assumptions
5Included scope: Interior wall paint, Interior walls and ceiling paint, Exterior wall paint.
Planning assumptions · 5
- Openings are deducted as simple rectangles. Trim, casing, closet interiors, and built-in millwork are not added back into the paint scope.
- Primer is planned as one coat. Patched walls, bare drywall, stain blocking, or dramatic color shifts can need more primer than this baseline carries.
- Coverage assumes smooth walls. Texture, porous surfaces, sprayer loss, and deep-base colors reduce the manufacturer baseline rates used here.
- Many finish paints are sold as paint-and-primer-in-one; the separate primer line is for bare drywall, patches, stain blocking, or major color changes. Uncheck the primer allowance if your walls do not need it.
- The BOM rounds packaged materials to whole purchase units such as gallons, bags, boxes, buckets, rolls, cartons, tubes, jars, bundles, or kits, so bought quantity can exceed the exact theoretical coverage shown by the area metrics.
Not included / Trade review
22 total scope notes to read before ordering or contractor handoff.
- Labor, permits, inspections, delivery, taxes, site prep, and site-specific engineering are not included.
- Pre-1978 homes may need lead-safe practices first. EPA RRP rules can apply before sanding, scraping, or demolition disturbs old coatings - verify with local rules and a certified professional.
