• Enter this number in the “Primer Coverage” field.
• Example: Most standard primers cover around 350 sq ft per gallon.

Step 3: Set Number of Coats

• Determine how many coats of primer you’ll apply.
• Enter this value in the “Number of Coats” field.
• Example: If you’re applying a single coat, enter 1.

Step 4: Calculate Primer

• Click the “Calculate” button.
• A progress bar will appear, simulating the calculation process.
• After a few seconds, the tool will display the total primer required.

Step 5: View and Share Results

• The result will appear in gallons.
• Use the “Copy Results” button to save the data or “Share Results” to send it to collaborators.

Practical Example

Imagine you are preparing to prime a medium-sized living room:

• Wall area: 500 sq ft
• Primer coverage: 350 sq ft per gallon
• Number of coats: 2

Calculation: Total Primer Needed=Wall Area×Number of CoatsCoverage\text{Total Primer Needed} = \frac{\text{Wall Area} \times \text{Number of Coats}}{\text{Coverage}}Total Primer Needed=CoverageWall Area×Number of Coats​ Total Primer Needed=500×2350≈2.86 gallons\text{Total Primer Needed} = \frac{500 \times 2}{350} \approx 2.86 \text{ gallons}Total Primer Needed=350500×2​≈2.86 gallons

With the calculator, you can instantly see that approximately 2.86 gallons of primer are required. No guesswork, no wasted material.
