Why is my Deep Pour Epoxy hazy or bubbly after mixing?
A hazy, bubble-filled Deep Pour mix is not a bad batch. Our epoxy is manufactured in an ISO 9000 environment in very large batches, so a defect would affect thousands of gallons at once. The haze comes from how the batch was measured, mixed or poured.
Check these first:
- Ratio. UltraClear Deep Pour Epoxy must be mixed 2:1 resin to hardener by volume, not by weight. For 10 oz of hardener, use 20 oz of resin. An incorrect ratio can cause bubbles to form in the batch.
- Air. A mix that turns white has had too much air mixed into it. Mix at a steady pace for the time given in the instructions.
- Bubble removal. Pour in 1/4" layers and wave a heat gun or torch across each one to pop the bubbles, building up to your 1" depth. Pouring 1/4" to 1" with no torching leaves the bubbles in place.
- Room conditions. Work between 60 and 85°F and keep the humidity below 60%.
Small test cups also cure more slowly than a full pour. A small batch or a thin pour generates less heat, so it takes longer than the 12-24 hours a 1" pour from a 1.5-gallon batch takes. That is by design; a pour that cured too quickly would be cloudy.
If you still get a white mix after following the instructions, contact us with details of how the batch was prepared and we will troubleshoot with you.
