Why do I keep getting fish eyes in my epoxy tumbler?

Substrate contamination is the most common problem that causes fish eyes and pin holes in epoxy seal coats. Dust, dirt, wax, silicones, even the oil from your fingers when touching the part prior to sealing with epoxy will deter epoxy resins from laying flat and curing with a perfectly smooth surface.

Why does my epoxy keep fish eyeing?

When a coating is applied to a substrate that is contaminated with low surface energy particles such as oil, wax, grease, or silicone, fish eyes may develop in the coating as it is applied. These fish eyes are produced because the coating is unable to wet out the contaminated area.

Why am I getting dimples in my epoxy tumbler?

Dimples can occur for 3 reasons: temperature fluctuation, micro dust particles and overtorching. To avoid getting dimples in your cured resin, make sure that the temperature in your resin room stays stable, that you use a dustcover and that you only lightly torch your resin!

What causes fish eyes in clear?

Dampen a clean rag in mineral spirits and wipe the surface again; the solvent cleaner will remove any grease, oil (including skin oil) or wax buildup. Any contaminants on the surface at all will result in fish eyes in the clear coat, so make sure you thoroughly clean the surface.

What are the reasons for the fish eye defect?

Fish eyes are a type of coating defect which is characterized by circular voids or separation in the coating. Fish eyes are small, crater-like openings in the finish after it has been applied. They are usually caused by oil and grease on a coating substrate.

Why do we get fish eyes?

Causes. Fish-eye disease is caused by mutations in the LCAT gene. This gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase (LCAT).

How do you fix fisheye?

Can I epoxy over fish eyes?

Care should be taken not to cut through the stain. Apply another seal coat of epoxy using an 1/8" nap foam roller, working to fill in the craters. Allow the epoxy to cure hard, sand entire application flat, and re-coat to finish.

Should you sand between coats of epoxy?

Sanding epoxy resin between coats will not only get out the imperfection, but will also serve to provide some tooth between the first and second layers.

How many coats of epoxy does a tumbler need?

Our crafters wonder typically how many coats of epoxy is enough for their tumbler. It does depend on what you're creating, but the average is 2-3 coats. To properly seal all the layers beneath, we recommend using a topcoat of your resin.

What causes powder coating fish eyes?

A fair amount of the time, fisheyes are caused by contaminants like oil, silicone, or water; either in the powder itself, on the substrate, or contaminating both during application. Oil and silicone are particularly notorious for causing fisheyes.

What does fish eyes look like?

Fish eyes are similar to the eyes of terrestrial vertebrates like birds and mammals, but have a more spherical lens. Birds and mammals (including humans) normally adjust focus by changing the shape of their lens, but fish normally adjust focus by moving the lens closer to or further from the retina.

How do I stop solvent popping?

How do you keep pinholes from painting?

How long do you let epoxy dry on tumbler?

Let The Tumbler Cure:

Leaving the motor running, allow the cup to continue turning until the resin is dry to the touch, approximately 18-24 hours later. Remove the tumbler from the cup turner and remove the tape. Allow the cup to continue curing - it will be fully cured at the 72 hour mark.

How long do I leave my tumbler on the Turner?

If you leave the tape on you'll end up sealing it under the epoxy layer. Let the tumbler turner spin the cup slowly for 6-8 hours.
