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 is my resin dimpling?
Dimples can occur when the resin cures in cooler temperatures, or if there is a temperature dip in the first 24 hours of a cure. Dimples can also result from surface contaminants ( such as dust particles ) landing in your wet resin.
Why is my epoxy bumpy?
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. This can lead to sticky spots in the cured resin. Surface preparation is often key to these problems, so make sure you have done yours well.
How do you fix fisheye 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.
Why do I keep getting fish eyes in my epoxy?
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.
What happens if you overheat resin?
If your resin overheats and smokes, you do not want to put it into a plastic or cardboard container. These can also leak or worse — catch fire. Do not throw the hot resin in your trash! The reaction is still occurring and can melt your trash can or start a fire.
Why is my epoxy not leveling?
Nearly all the epoxy resins you can purchase are self-levelling. However, if you find your epoxy resin is not levelling out properly, it could mean you are using too little resin. So, if your epoxy has already cured properly, you will need to sand down the surface and apply a second coat.
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 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.
Why would epoxy resin get hot?
When you mix Part A (resin) and Part B (hardener) together new chemical bonds begin to form causing an epoxy exothermic reaction. Energy is released in the form of heat as the mixture catalyzes.
Why did my epoxy resin get hot?
The main reason that epoxy gets so hot is due to the exotherm during the curing process. When base epoxy resin and the hardener (curing agent) are mixed, there is a chemical reaction that causes them to heat up.
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.
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.
Can you over mix epoxy resin?
If you mix too vigorously, you can trap air and introduce bubbles. If you’re overly enthusiastic, you’ll get a “foamy” epoxy that looks like whipped cream. Note that a few bubbles will appear in properly mixed epoxy.
What happens if you use too much hardener in epoxy?
Too much or too little hardener will affect the cure time and thoroughness of the cure. A. Remove the uncured epoxy. Do not apply additional material over non-curing epoxy.
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.
