2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( \text{Area} \) — Total area to be covered (square feet)
• \( \text{Coverage Rate} \) — Adhesive coverage rate (square feet per gallon)

Explanation: This calculation helps determine how many gallons of adhesive you'll need for your subfloor project.

3. Importance of Proper Adhesive Calculation

Details: Accurate adhesive calculation ensures you purchase the right amount, avoiding waste or project delays from insufficient materials.

4. Using the Calculator

Tips: Measure your floor area accurately. Check the coverage rate on your specific adhesive product (typically 150-300 sq ft/gallon). Always round up to the nearest gallon.
