Mobile Home paint calculator
Single-wide mobile homes (typically 14 × 70 ft) have ~1,000 sq ft of floor and ~2,500 sq ft of paintable wall. Double-wides run ~1,800 sq ft floor and ~4,000 sq ft walls. Mobile homes have unique paint considerations — wall panels are often vinyl-coated gypsum (VCG), which doesn't hold standard paint without prep.
Estimates round up to the nearest quart and are based on Kompozit's published coverage. Buy slightly more for touch-ups and color changes.
Vinyl-covered gypsum walls need bonding primer
Most mobile home interior walls are VCG: standard drywall with a vinyl decorative facing. Standard paint peels off it. Use a bonding primer first — Kompozit PRIME works — and topcoat with PRO satin. The vinyl facing seam joints are hidden by paint after a topcoat or two.
Exterior siding: depends on era
Older mobile homes have aluminum siding (paints with bonding primer); newer ones have vinyl (only paint with vinyl-safe topcoats — never paint vinyl in dark colors, the heat absorption can warp the siding).
