Estimate drywall mud, tape, and screws.
Enter the installed drywall area to convert coverage assumptions into gallons, linear feet, pounds, and practical package counts for ordering.
Installed-area input
Convert square footage into finish materials.
Use installed area before board-order waste. These materials cover the drywall actually hung and finished, so BoardCount does not add the sheet waste percentage here.
