There are a few reasons why part of the resin could cure cloudy or have bubbles.
1.If the resin is too cool when you pour it. If it is stored in a cooler spot and not properly warmed up to room temperature of 70+ degrees then it can become cloudy or have more bubbles when pouring. After pouring if you torch the surface enough before it cures it will warm those areas then the cloudiness will usually go away and the bubbles will be released. Wave the torch 4 to 6 inches from the surface. (Another tip is before you start to warm the closed part A resin bottle in a warm water bath before mixing it with part B to warm it back up. You will still need to apply the torch but it helps starting with warmer resin)
2. If the resin is poured too deep then the surface can become cloudy because bubbles can get trapped in the deeper part and the torch won’t be able to reach them.
3. If areas of the mixture weren’t mixed thoroughly they can sometimes become cloudy or not cure properly.
These are things to keep in mind for the future to avoid it happening.
How do I fix cloudy resin or resin with bubbles?
The best way to fix your project if it cured with bubbles or is cloudy is to lightly sand out the area of concern. Wipe any dust off with acetone and make sure the surface is fully dry. Apply another thin coat to the area following the proper mixing instructions below.
Mixing Instructions for best results: First place the Resin Part A bottle with the lid tightly fastened in a hot water bath to warm up the resin.Make sure your resin bottle is completely dried off before mixing. You don’t want to get any water in the mix because that could prevent it from curing.
Then take graduated cups and measure equal parts of part A and part B. It’s best to add hardener 1st then add the resin because the resin consistency is thicker. Mix the cup of part B and part A together. Stir for 4 minutes making sure to scrape all the edges and base of the cup to make sure everything is stirred into the mix. Transfer your mixed part A and B into a separate cup to make sure the bottom of the original cup doesn’t have any unmixed areas. Then it is ready to pour.
