1. What is Paint Mixing Ratio?

The paint mixing ratio refers to the proportion of different components (usually Part A and Part B) that need to be combined to create a paint mixture. This is especially important for two-component paints like epoxies and polyurethanes.

2. How Does the Calculator Work?

The calculator uses the paint mixing formula:

Where:

• \( Total \) — Total desired mixture volume
• \( Ratio \) — Mixing ratio (A:B)

Explanation: The formula calculates the volume of Part B needed, then Part A is the remaining volume to reach the total.

3. Importance of Proper Mixing

Details: Correct mixing ratios are crucial for paint performance, including proper curing, durability, and appearance. Incorrect ratios can lead to poor adhesion, reduced chemical resistance, or incomplete curing.

4. Using the Calculator

Tips: Enter the total volume of mixed paint you need and the mixing ratio specified by the manufacturer (e.g., for 4:1 ratio, enter 4). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What happens if I mix paint in the wrong ratio?
A: Incorrect ratios can cause various problems - too much hardener may make the paint brittle, while too little may prevent proper curing.

Q2: Should I mix by volume or weight?
A: Most manufacturers specify volume ratios, but some professional applications use weight. Always check the product datasheet.

Q3: How precise do I need to be with mixing?
A: For best results, stay within ±5% of the recommended ratio. Some products are more sensitive than others.

Q4: Can I mix partial ratios?
A: Yes, as long as you maintain the same proportion. This calculator helps with partial mixes.

Q5: How long can I use mixed paint?
A: Pot life varies by product - typically 1-8 hours at room temperature. Mixed paint should be used within this time.
