PuDuo Epoxy Resin Instructions

Updated: Jul 13

This information has been copied, from the PuDuo insert that comes with your resin kit, in case you misplace it.


Please read these instructions in their entirety before starting your project. Attention to the instructions for your project (casting vs coating).



Set up: Find a well ventilated, dust free area to set up your resin pour. The temperature should also be roughly in the 70F (21C) to 80F (27C) range, but 65F (18.3C), minimum for the resin to cure properly. Lay down a plastic drop cloth to protect your table and/or floor. You should also have nitrile gloves, protective eyewear, paper towels, mixing sticks (wood and plastic both work), plastic cups for mixing, measuring cups (optional), and your prepared mould (optional), a foam brush (for table coatings), and lacquer thinner or isopropyl alcohol for clean up where/if needed.


First, you will need to figure out how much resin you will need for your entire project, including all of the different colours if applicalbe (refer to coverage info at the end of this document to calculate how much resin is needed when coating a table or bar). Or ArtWorks Resin Canada has a couple of calculators you can use as well. Keep in mind; it is always better to have a little extra resin left over than it is to have to mix up another batch of it mid project.


Pour equal parts of resin (part a) and hardener (part b) into two cups and then pour those cups into a third mixing cup (or you can use an accurate measuring cup (and just use the measure lines). It is normal that you might feel the cup may get warm because it is a faster dry type of resin. It is extremely important that you mix thoroughly in this cup, making sure to scrape the sides and bottom of the cup as you stir. Mix for 3 to 5 minutes, or until there are no "streaks" or striations left in the resin as you are stirring. This helps to eliminate the risk of soft spots. Pour your mixed resin in to a new cup and stir it for another 20-30 seconds or until all the striations are gone for sure. This eliminates the possibility of unmixed resin from the sides or bottom of the first cup from causing soft spots. It is free insurance so DO IT Please! :-)


You can either pour this resin as is for a clear finish or you can mix in any colour at this time. If you are using more than one colour, pour the clear resin from the mixing cup into new cups, one for each colour, and then stir in your pigments thoroughly. If using powders, check they are fully dissolved.


Once mixed, you should quickly but carefully pour your resin into your mould or substrate (table, canvas, wood panel, tray, etc). Cover you completed work with a plastic bin or cardboard box if possible, to help keep dust, and hair in the air from landing on it. Check piece in about 10 minutes for any air bubbles. For smaller castings, bubbles can be popped with a toothpick.


Your finished casting can be removed from the mould after 10 hours, and full cure is after 24-48 hours depending on the temperature and mould sizes. PS: Our resin will be thicker or higher density when it is colder weather. So we suggest to warm the resin before you start your project in order to get best results. Just put the bottle into warm water, roughly 176F (80C), for about 2-3 minutes.


Be aware, PuDuo resin will not cure within 8-10 hours for smaller crafts like earrings, pendants or thinner castings (such as rulers), and it will most likely need to be left for 24-48 hours to properly cure. The more resin put in a mould, the more heat is produced which will speed up the curing time.




Table/Bar Coating specific instructions:


Place a drop cloth underneath table or work area, and verify your table is level. Wipe the table off with a damp rag and allow it to dry completely. It is recommended to seal porous surfaces such as wood, with a thin coating of the mixed resin using a squeegee or foam brush prior to doing the main resin pour. Let cure for 6 hours. (Or you can use a primer/sealer product, but it must be fully cured prior to adding a resin layer). If your surface is not porous or has been sealed previously skip this step.


Create a barrier using masking tape or painter's tape around the edges of the table top, if the top doesn't already have a raised rim of its own. Press the tape in place around the entire table top with the tape sticking up at least half an inch.


Place the objects you wish to trap in the resin on the table top surface. Keep in mind that pouring the resin over items, may move them, so you may need to affix lighter objects first, so they don't float. If gluing down a photograph (should be sealed first), or image for example, while the glue is wet, use a roller or smooth round bottle to roll out any air bubbles from underneath the print. A glue gun can be used for objects such as coins, bottle caps or any other loose items that may need fastening prior to pouring resin.


Mix enough resin to create a thin coating at a maximum thickness of 1/4" (.635cm), see chart below as a guide. If you need to pour several layers for added thickness, wait for each layer to cure for 6 hours prior to pouring the next coat. Subsequent coats beyond 24 hours require a light sanding with 220 grit sandpaper. After sanding, wipe down the surface with a solvent such as denatured alcohol, isopropyl alcohol or acetone.


Note, larger pours may require mixing for more than 5 minutes, and it is recommended to not mix more than 1 gallon at a time. Never leave your resin sitting in the mix cup. Pour a thick layer of the resin mixture onto the top, pouring it slowly in a thin stream onto the center of the surface. Fill any indents or flaws in the table's surface with the mixture by using a foam brush to guide the resin into these indentations. Continue pouring until the entire table top is coated. After a few minutes, air bubbles may rise to the surface, use a propane torch (on low flame) to remove the bubbles. Hold the torch approximately 8 inches (depending on torch size) from the surface, (not allowing flame to touch resin), and using a gentle slow moving pace, wave the torch over the whole surface. Do not hold torch in one spot or area as that can damage the surface and coating. Keep torch away from any items that might be flammable (paper cups, taped edge, etc.).


Second and subsequent pours over table:

Allow the first coat to cure for 6 hours before making a second pour. Remove the tape rim from the perimeter of the table and create a fresh taped rim around the table top. Mix a new batch of resin, making a slightly larger batch than before. Pour the resin mixture slowly onto the table top until the entire top is coated. Apply additional coats, as needed, using a fresh rim of tape each time. After applying the final coat, allow the table to cure for 24 hours. You can spray your fully cured epoxy table surface with a UV resistant acrylic spray if desired, for added protection against the outdoor elements. Note; All epoxy will eventually yellow after prolonged UV exposure. We recommend you allow the table top to cure and harden for 5 days before placing objects on it.
