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.
How do you fix dimples in 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.
Why does my epoxy tumbler have dimples?
A: Dimples can occur for 3 reasons: 1) If the temperature fluctuates in the room while the ArtResin is curing during the first 24 hours. Make sure that the temperature stays stable in the room ( 72-77F or 23-25C ) while your piece cures. 2) If you get some dust particles in your piece.
How do you smooth out 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.
Why did my epoxy fisheye?
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.
How do you prevent fisheye in epoxy?
This can be avoided by sanding with 120-150 grit. Allow the existing epoxy to cure hard and block sand flat using 120-150 grit until leveled. If the cratering is minimal, you can use a squeegee to fill in those areas with epoxy and then sand flat. Proceed by re-coating with epoxy.
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 resin bumpy?
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.
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.
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 many coats of epoxy does a tumbler need?
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. For a sparkling finish, you can mix in glitter from our friends at Alumilite to realize your epoxy glitter tumbler vision.
Should you 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.
Can you put polyurethane over epoxy?
Both oil-based and water-based polyurethane can be applied over epoxy, although oil-based polyurethane may leave an amber hue (while water-based will be more clear). To ensure proper application, be sure that the epoxy has completely sealed/hardened, and sand first to allow for a mechanical bond.
Can you sand epoxy and recoat?
A lot of first-time users ask, “Can you sand epoxy?” The answer is, YES! This is the primary way to prepare your epoxy for a second coat.
Can I put Modge podge over epoxy?
Cover the curing resin so dust does not ruin the finish. Use an inverted box for multiple items or cups for individual items, leaving space for air to circulate. To prevent discoloration, seal both sides and edges of the image with Mod Podge® or Elmer’s® Glue-All®. Let adhesive dry completely before adding resin.
Why is my resin wavy?
Sometimes, resin components can crystallize when the kit has gotten too cold. These crystals can show up as swirls or waves in resin. Before using the kit again, gently warm it in a warm water bath. Moisture has contaminated the resin.
Is one coat of epoxy enough?
Manufacturers may suggest two coats of epoxy paint and topcoat, but most standard kits only supply enough for one coat. If you choose to add color flakes, which will help hide concrete’s inherent imperfections, determine how heavily you’ll broadcast them across the floor so you don’t come up short.
How do you get bubbles out of epoxy after it dries?
Yes, you CAN get rid of bubbles after your resin has dried! Simply sand down the entire surface of your piece, making sure you pay special attention to the areas with bubbles. Wipe away all the sanding residue with a damp paper towel. Apply a fresh coat of carefully measured and mixed ArtResin epoxy resin.
