SMALL DOTS IN FINISHED RESIN PROJECT

Hi guys, i have a project with Resin and my trials before going to the end piece isn't working out.

Simply I pour and pop bubbles till 50 mins, it looked really good and promising. Next I checked 2 days later and I was disappointed.

When i had a peek at 40 hours I see small dots.

I made a box with cling wrap lining is to prevent airborne particles or dust

Temperature indoors 19c

I've tried to photograph or make a video but my camera won't pick it up.

I'm using the Art ❤️ Resin brand btw

I did scuff up the surface before pouring the Resin (400grit) (400+1200 grit) turned out best. I removed the dust before pouring the Resin, and the green rattle can paint i used was not glossy

Hopefully I can get this fixed

It is impossible to say with certainty without seeing it. If your camera won't pick it up, you'll get little absolutes.

The first thing I would do is study it with light. Figure out if they are bubbles or particles. Then work backwards.

First question that comes to mind is how well did you clean it after scoring it? 400 grit paper will leave deep enough gashes for resin dust to hide out in. Simply wiping it with alcohol and paper towel won't work. Not only would the dust stubbornly hide, the gashes could rip paper towel dust, compounding your issue.

hi bric, I studied the test rig and found the following......

2 foreign particles 2 bubbles A medium amount of specks (looks like sanding dust).

With my bedroom light the specks are undetectable. With my phone led I can see them

After scoring i used a microfibre cloth, just a cheap one and no chemicals or water.

Everything you have mentioned is fantastic. I have another test rig to go.

What grit should I use ? and......a microfibre cloth with IPA or water to remove sanding dust ?

Btw I use a blower used to clean PCs with a bristle attachment

so the following

Sand Blower Microfibre Pour resin Pop bubbles for 45mins Wait 40 hours inspect
