Do not brush over inconsistent epoxy seal coat areas, that will most likely reduce the surface tension and result in a larger fish eye or separation. A drip of extra epoxy is all you need on the area to solve the issue.
How do you cover fish eyes in epoxy?
Lightly sand the existing epoxy with 120-150 grit. 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.
What is a fish eye in epoxy?
Fish eyes are where a coating pulls away from the underlying surface creating ‘holes’ or craters in the topcoat that go down to the bottom coating. They sometimes happen under certain conditions with epoxies. Two part polys (LPU) coatings are especially sensitive to fish eyes.
How do you fix fish eyes in polyurethane?
To eliminate fish eyes from an old, already hardened but otherwise satisfactory finish, first wash down the surfaces using a cloth dampened with mineral spirits to get rid of wax and dirt. Then wear down the finish gently with 320 waterproof abrasive paper lubricated with a splash of water.
What causes divots in epoxy?
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!Feb 13, 2019.
Why is my epoxy not sticking to my cup?
Mixing ratios can greatly affect how your piece will cure. If the mixing ratio is off or not completely mixed properly, this can cause the resin to remain tacky, or have soft spots. To ensure that you have the proper mixing ratios measured in measuring cups, and to ensure that you are mixing by volume.
How do you fix dimpled epoxy?
Whether your divots occurred during the pouring process of your countertops, or afterwards due to a soft cure, the solution is always to pour another coat of epoxy. You can pour directly over the previous epoxy pour within 24 hours of the first pour.
Can you buff out fish eyes?
Fish eye (Fig. 10) is caused by a contaminant on the surface prior to application of paint. After the paint is fully cured, if slight remnants of the fish eye are visible, it can be sanded and polished.
Why isn’t my epoxy smooth?
The most common cause for uneven epoxy resin is often not using the correct mixing ratio, or even using hardener and resin that is too old. These problems can be prevented by ensuring your work area is well ventilated, not too humid, and using a torch to heat the epoxy and allow the air bubbles to escape.
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 am I getting fish eyes in my polyurethane?
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.
How do you fix fisheye?
SOLUTION Remove wet paint film with solvent, clean and refinish. Add the recommended fisheye eliminator and respray the affected area. If fisheyes appear in a basecoat, allow the color to flash then spray a mist coat over affected area.
Why is my epoxy so thick?
Temperature The ideal room temperature for mixing ArtResin epoxy resin is between 75 and 85 degrees F or 24 – 30 degrees C. If it’s colder than that, the resin will be thicker and harder to mix, will have more bubbles and will take longer to cure until it’s dry to the touch.
How do you fix white spots on epoxy?
Sanding with dull paper can heat the epoxy and soften it, and result in the same ‘white’ look with dust mixed with softened epoxy. Wet sanding (water and a drop of dishwashing detergent, using wet/dry sandpaper) usually works better for me. Don’t be afraid to experiment a bit. With epoxy, you can always sand off extra.
How do you stop air bubbles in epoxy?
A small amount of baby powder can work to reduce bubbles in resin. If you are using colored resin, you can even choose a powder that matches the color of the resin you are using. Use a delicate paintbrush to dust in the powder, then tap out any extra before pouring.
Do you have to sand between coats of epoxy?
Sanding will not only get out the imperfection but will also serve to provide some tooth between the first and second layers. It will look very scuffed in the short term but do not worry, once you pour the second coat over top, all of those sanding marks will disappear.
How do you get rid of clear fish eyes?
Does Fish Eye Eliminator work?
Fish eye eliminator (FEE) usually increases the amount of texture (orange peel) in the finish and causes any materials laid on top NOT to bond properly. If a surface is cleaned properly and you have a decent filter on your compressed air you should have no problem with fish eyes.
What causes fish eyes?
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 smooth epoxy?
Wet sanding with waterproof sandpaper is often the best approach to sanding cured epoxy resin. Wet sanding removes unevenness while you are sanding, reduces clogging of the abrasive paper and drastically reduces the amount of dust emitted into the air.
