Dry-Sponge Soot Cleaning Takeoff and Seal Coat
Turns soot-affected wall and ceiling area into the chemical sponges, labor hours, and odor-seal primer the dry-smoke cleaning phase consumes: sponges from a per-sponge coverage, labor from a production rate, and primer gallons from a coverage rate. The residue type governs the method, so dry sponging is for dry smoke; protein, wet, and fuel-oil residues need wet cleaning. A quantity screen for a fire estimate, not a cleaning protocol. IICRC S700 governs.
Formula and source
dry_sponges = ceil(affected_sf / sponge_coverage_sf); labor_hours = affected_sf / production_sf_per_hr; sealer_gal = seal_coat ? affected_sf / primer_sf_per_gal : 0.
Dry-sponge soot cleaning takeoff and the 300 ft^2/gal primer coverage, by name; ANSI/IICRC S700 fire and smoke restoration. Field-takeoff arithmetic, not edition-bound.
