Reference tables
Look-up charts built from stable conventions — material coverage & waste factors, paint per gallon, drywall sheets per sq ft, tile/flooring waste, cost-per-sq-ft planning bands and a renovation project-phase checklist.
Material coverage & waste factorsHow far common finish materials go and how much extra to order — paint sq ft per gallon, drywall per sheet, and typical tile/flooring waste, as labeled planning bands.Paint coverage — sq ft per gallon per coatTypical interior paint coverage of ~350–400 sq ft per gallon per coat, with the gallons needed for common room sizes at two coats — a labeled planning band.Drywall sheets per square foot (4×8 = 32 sq ft)How many 4×8 drywall sheets (32 sq ft each) a given wall/ceiling area needs — the fixed convention behind the drywall calculator.Tile & flooring waste factorsTypical order-extra (waste) percentages for tile and flooring — 10–15% by layout — as labeled planning bands, not a rule.Renovation cost-per-sq-ft PLANNING bandsRough per-square-foot planning bands for scoping a renovation — labeled estimates for a first pass, NOT a current price index or market pricing.Standard renovation project phasesA standard sequence of renovation phases — from planning and permits through demolition, rough-ins, finishes and punch list — as a timeless checklist.
