Frequently Asked Questions

  • What causes epoxy not to cure?
    There may have been too much or too little hardener, which directly affects the cure time of the batch. Insufficient mixing. You may not have mixed long enough for the resin and hardener to be adequately mixed for a proper cure. Always mix thoroughly for a minimum of 5 minutes.
  • Can you pour epoxy in layers?
    Yes, you can apply a second coat of resin if you need to fix a mistake or a surface imperfection. You can also pour multiple layers if you need to cover areas of high relief, if you're pouring into a mold or if you simply like the look of a thicker coat.
  • What happens if epoxy gets too hot?
    This uncontrolled heat build-up is called uncontrolled exotherm. Epoxy heating out of control can foam, smoke, give off dangerous vapors and generate enough heat to melt its container or cause nearby items to catch fire.
  • Why is my epoxy sticky after drying?
    Sticky, tacky resin This is often caused by inaccurate measuring, not mixing thoroughly or by curing in cold temperatures. Try moving your piece to a warmer spot: if it doesn't dry, re-pour with a fresh coat of resin.
  • 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. You can pour the next layer after the previous pour has gone through its heat cycle, which is usually around 24 hours.
  • Can I sand epoxy after 24 hours?
    Tip: The epoxy resin must be really dry before sanding. You should therefore allow a waiting period of at least 48 hours before processing. Follow the manufacturer's instructions, as there are resins that take even longer to harden completely.
  • Can you epoxy over glass?
    Besides being a fun medium to create with, epoxy resin is also an excellent glue. You can use it to bond jewelry findings to your resin charms. Also, epoxy resin glues to glass very well, provided the surface is clean. That means if a glass surface is free of dirt and oil, resin will stick to it with no trouble
  • Can you layer different brands of epoxy?
    I have done this with different brands of resin before and it has worked for me. I would suggest making sure the layers are completely cured first and that you're using the same type (e.g don’t do a layer of epoxy, then a layer of polyester, etc.) Let us know how it works out for you! If you are a beginner don’t do it, get some practice in first.
  • Why do you spray alcohol on resin?
    You can use alcohol spray for resin bubbles. Fill a spray bottle with rubbing alcohol and spritz the surface of the resin. The alcohol breaks the surface tension causing the bubbles to pop and you'll see the bubbles pop right before your eyes.
  • Why is my resin bendy after 48 hours?
    Short Cure Time In most cases, the reason you have resin that bends is due to the fact that the resin needs more time to cure. After 24 hours, ArtResin will be at a 95% solidity rate. If you attempt to curve or move the resin before that 24 hour mark, the resin will likely bend. This can also happen when the mixture is wrong.
  • Does epoxy resin need air to cure?
    No ,epoxy hardens by chemical reaction rather than evaporation like wood glue does.
  • What causes micro bubbles in epoxy?
    Air bubbles introduced into the epoxy during the mixing process. This can be due to the epoxy user mixing too vigorously or for too long. You don't want to whip the hardener and resin together quickly and pull a lot of air into the mixture.
  • What can I do with leftover epoxy resin?
    Stop wasting your resin! use extra resin on a small project. create alcohol ink coasters. brush on small amounts. leftover tinted resin. make a 3d collage. make resin crystals. pour into a small mold. layer your leftovers. what to do with partially leftover cured resin. make a trinket dish.
  • Does temperature affect epoxy curing?
    The warmer the temperature of curing epoxy, the faster it cures . Heat speeds up epoxy chemistry or the chemical reaction of epoxy components.
  • Is burning epoxy toxic?
    When epoxy fumes are inhaled, they can affect the nose, throat, and lungs. Most symptoms from the inhalation of epoxy involve inflammation and therefore irritation of the nose, throat, and lungs. Repetitive and high amounts of exposure to these fumes can result in sensitization and asthma.
  • Can you mix epoxy with water?
    Never add Water to the Epoxy Resin.
  • Will cured epoxy crack in cold weather?
    Epoxy is a common floor coating material. Epoxy will not crack in freezing temperatures. The effects of freezing weather on epoxy only reduce its ability to cure properly.
  • Why is my epoxy not getting hard?
    If your ratio of resin to hardener is off, your resin will not harden. If the ambient temperature in your workspace isn't ideal, or if your resin mixture has been contaminated, this could also cause your resin to not cure correctly.
  • Is epoxy heat resistant?
    Usually, Epoxy can withstand up to 150 degrees / 300° Fahrenheit for a short period of time. Heat-resistant epoxy can withstand extreme heat of up to 600° Fahrenheit depending on the manufacturer and product.
  • Can you store mixed epoxy?
    Do not store mixed resin. Once it's mixed you have to use it or lose it. Otherwise, you will have a hard block of resin when you go to use it.
  • Which ratio resin is best?
    The right Mixing Ratio Typically, this is 1 : 1 or 2 : 1 between resin and hardener, but there are also much more complicated ones such as 100 : 45. You can usually find the details on the packaging or containers. We stick to the 1:1 Olloggin Art Resin and the 2:1 Olloggin Deep Pour.
  • Should you wear a mask when using epoxy?
    Provide ventilation and wear a dust/mist mask or respirator when sanding epoxy, especially partially cured epoxy. Breathing partially cured epoxy dust increases your risk of sensitization.
  • What is Sublimation Printing?
    Firstly, what is sublimation printing? Sublimation printing is a popular method of printing which aims at transferring a design from sublimation paper onto a piece of fabric or material by using pressure and heat (between 350 – 400 degrees). Changing the solid particles of the ink into a gaseous state, it is an easy and cost-effective way of adding personalization to products that is used by both companies and people at home. The high-quality end product of sublimation printing has resulted in its popularity increased over the past few years. However, like all forms of printing, it is essential that you know how to create the designs (by watching tutorials or reading guides like this one) before you try it for yourself.
  • What is the difference between sublimation printing and regular printing?
    Inkjet printers print liquid ink on top of paper, while sublimation printers permeate the material with ink vapors. Sublimation printing is best suited for printing graphics onto plastic substrates.
  • Can any printer be used for sublimation?
    Inkjet printers that use a thermal printing head cannot be used for sublimation printing. As a result inkjet printers manufactured by Canon, Hewlett Packard (HP), Lexmark or Dell are not suitable. Printers that use a Micro Piezo printing head can be used for sublimation printing.
  • What is the difference between sublimation printing and regular printing?
    Inkjet printers print liquid ink on top of paper, while sublimation printers permeate the material with ink vapors. Sublimation printing is best suited for printing graphics onto plastic substrates.
  • Is a CNC router worth it?
    They are hugely efficient at cutting curves accurately. But they are not so efficient at cutting square/rectangular parts. You'll be much quicker on your table saw. They can be efficient at cutting pockets out of material, but so can a simple jig with a handheld router.
  • Can you CNC MDF?
    MDF lends itself perfectly to CNC machining, and CNC Creations can expertly cut and create shaped, routed and grooved MDF panels up to a maximum size of 3660mm x 1525mm (12ft x 5ft).
  • Can a CNC router cut acrylic?
    Acrylic can be cut using CNC mills or CNC lathes. CNC lathes are generally used for softer materials like wood, foam, plastic, and aluminum, and rotate the part using a stationary tool. A CNC milling machine is very precise because it uses a multi-point cutting tool that can move along different axes.
  • What kind of bit do I use for CNC acrylic?
    When processing acrylic using a CNC router, solid carbide, up-spiral “O” flute router bits will produce the best results. They are available with one, two or three flutes. Common bit sizes are 1/8" to 1/2" diameter.
  • What is Blu in CNC?
    In a CNC machine BLU represents the smallest distance. Revolution of motor in one step = 1/200 rev./step. movement of the lead screw = (1/200)× (1/4) = 1/800 rev. of the lead screw. Movement of the lead screw is transferred to the table.
  • Can you laser engrave anything?
    The materials that the laser can cut materials like wood, paper, cork, and some kinds of plastics. Etching can be done on almost anything, wood, cardboard, aluminum, stainless steel, plastic, marble, stone, tile, and glass.
  • What is the difference between engraving and laser engraving?
    The main difference between laser etching and laser engraving is that etching melts the micro surface to create raised marks, whereas engraving removes material to create deep marks.
  • How long do laser engravers last?
    The general life of the laser tube is 5,000-10,000 hours. In the state where the current ratio is relatively small, it is no big problem for the laser tube to continuously emit light for 4 hours, and it will not cause too much damage to the laser tube itself.
  • Is engraving permanent?
    What is Laser Engraving? The laser engraving process releases enormous energy acting like a chisel to the workpiece's surface to create deep and permanent designs.
  • What metals can you laser engrave?
    Which metals are suitable for laser marking and engraving metals? Anodized aluminum Stainless steel Natural aluminum Brass Copper Coated metals AlumaMark® DuraBlack®
  • What wood is best for laser cutting?
    Hard Woods Birch, maple, cherry, mahogany, walnut, and oak are beautiful materials to work with and are favorites for laser cutters. They require more powerful lasers because of their density, but thick sheets can still be cut with the right power.
  • Do you sand after laser engraving?
    Sanding down your product will help remove residue left from the engraving and cutting process providing you with a cleaner and more professional-looking finish. If sanding down on a flat surface, wrap the sandpaper around a wooden block. Instead of using your hand.
