What is a cold patch calculator?
A cold patch calculator is a planning tool that combines a repair's area and depth with coverage information for a specific cold-patch product. It estimates the material or number of packages needed; it does not determine whether the pavement is suitable for a surface patch.
How does a cold patch calculator work?
A traditional calculator starts with dimensions measured by the user. It applies the selected product's stated coverage method and rounds to purchasable units as that method requires. Coverage tables, package yields, supported depths, and rounding rules can differ, so the exact product instructions control.
How much cold patch do I need?
Cold-patch quantity depends on the repair dimensions and the coverage specifications of the exact product being used. Measure the area and representative depth only after confirming that the damage fits a localized patch workflow, then apply that product's current coverage data.
The guide to planning cold-patch quantity explains the measurement and product-data checks in more detail.
How many bags of cold patch do I need?
The bag count comes from the selected product's coverage data, not a universal pounds-per-pothole rule. Use the stated package table or yield for the measured area and depth, follow its section and rounding rules, and round to whole purchasable bags only at the point the product method specifies.
For Gem Patch, Patcher uses the verified six area-by-depth values and does not extrapolate a standard recommendation past the stated maximum depth. The product page keeps the manufacturer coverage table available for reference.
Do I need to measure a pothole manually?
A traditional calculator requires measurements you obtain and enter manually. Patcher's photo workflow can establish dimensions only when submitted scale, depth, and boundary evidence supports them. Otherwise it asks for another view or returns you to safe manual measurement.
If you are measuring by hand, review how to measure irregular pavement damage.
Is there an alternative to a cold patch calculator?
Patcher is an alternative workflow rather than another generic calculator. The web and iPhone workflows assess photo evidence, plan quantity using verified product information, continue into ordering, and keep current product information within reach.
From damage to repair
- Check the visible damage pattern and stop if the condition points beyond a localized patch.
- Measure the repair manually or use Patcher's photo workflow.
- Apply verified coverage information for the exact selected material.
- Confirm quantity and order details in Patcher.
- Follow the current instructions for the product delivered.
Start with the repair, not a guessed bag count.
