What happens if you pour epoxy too thick?
If your epoxy pour is too thick, the reaction can create too much heat, resulting in a product that does not cure properly with cracks or excessive bubbles. The rule of thumb is if you can make an imprint with your fingernail in the epoxy you can pour again and the epoxy will chemically bond to the previous layer.
Can you pour epoxy over cured epoxy?
Can I put another coat of epoxy over cured epoxy? Yes. Since the epoxy has cured a chemical bond is not possible so what is called a mechanical bond is needed. This simply means that the cured epoxy has to be lightly sanded before the next coat is applied: the first coat should have a matt, almost white, surface.
Why is my epoxy bumpy?
Surface Imperfections This problem can be caused by anything floating/falling into your resin while it cures, resulting in imperfections in the surface. If you are experiencing imperfections that look more like domed bumps in the resin, skip down to #4.
When can I take resin out of mold?
How Long Will It Take For My Pieces To Harden? Little Windows Brilliant Resin is designed to set up in 12 hours, so you can remove it from your molds or Doming Tray after that time. For the first day your pieces will be a bit flexible, so this is the easiest time to drill and finish your creations.
How do you even out epoxy resin?
An uneven hardening of your epoxy resin can lead to dull, or even tacky spots. To fix an uneven epoxy finish, wait until the epoxy has dried thoroughly, and then sand it lightly with fine-grained wet sandpaper. After this, make sure to wipe down the surface, so it is entirely free of any sanding dust and other debris.
Why is my resin bendy after a week?
In most cases, the reason you have resin that bends is due to the fact that the resin needs more time to cure. If you attempt to curve or move the resin before that 24 hour mark, the resin will likely bend. For a full cure, we recommend waiting 3 – 5 days to ensure that the resin is 100% firm.
How do you fix resin that didn’t cure?
How to easily Fix Wet/Soft Resin Use a sandpaper: we recommend 80 or 90 grit coarse sand paper. Sand down the cured surface and clean away with napkin. Remove gooey resin as much as you can. Once you’ve scraped and surface is clear of dust, then pour a new coat of Baltic Day resin.

How long does it take 2 part epoxy to dry?
Usually, it takes around 72 hours to fully cure the epoxy. Whatever the dry time, the resin should be allowed to fully cure before attempting to move or sand it. If the epoxy isn’t allowed to rest until fully cured, your project will be prone to surface contamination.
