3M Mix Ratio Insert Pack

This pack contains one hundred transparent plastic inserts designed for the 3M Paint Preparation System 850mL cup. They suit professional painters and bodyshop technicians who mix coatings regularly. Each insert displays ratio markings for common blend proportions.

Installing the inserts

Drop an insert into the cup before pouring components; the flexible plastic seats itself against the wall. The clear material lets you verify alignment with the tri-scale printed on the cup. A common error is using a worn cup where the scale has faded, causing misread ratios.

Check your mixing setup

Confirm you are using the 3M 850mL cup that carries the matching tri-scale. The inserts support 1:1, 2:1:1, 4:1:1, 6:1:1 and 8:1:1 ratios only. They will not fit smaller cups or systems from other brands.

Questions about this item

How can I verify the mix ratio insert is seated correctly in the 850mL cup after setup?

The transparent plastic insert should sit flush inside the 3M Paint Preparation System 850mL cup with the ratio markings visible through the cup wall for 1:1, 2:1:1, 4:1:1, 6:1:1 and 8:1:1 mixes.

What comes in the pack and do I need to buy the mixing cup separately?

The package contains 100 large generic mix ratio inserts; the 3M Paint Preparation System 850mL cup is not included and must be purchased separately.

Which version of the insert should I choose for the 850mL cup and tri-scale ratios?

This single version (16091) is the large generic insert designed for the 850mL cup and covers 1:1, 2:1:1, 4:1:1, 6:1:1, 8:1:1 ratios plus 3M Tri-Scale markings.
