Can you do multiple pours of epoxy?
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.
Most projects need between two and four. However many coats you're planning on, you need to recoat at the right time and in the right way and ensure your surface is properly prepared.
After you've applied your first coat of ArtResin, wait about 3-5 hours until it starts to thicken and reaches a gel like state. At this point, you can pour the next coat on top. The stickiness of the resin will provide the tooth and the two layers will cure simultaneously, creating a very strong bond.
It will look terrible when you finish sanding it, but don't worry. After you pour the second coat of epoxy, it will look good as new! Depending on the epoxy you've chosen to work with, you'll have to wait between 4 and 24 hours before applying your second coat.
The layer is too thick
Each epoxy resin system has a “safe” pour depth at room temperature. If you exceed that depth the transfer of heat becomes problematic. If exceeded as the chemical reaction “kicks off” the amount of thermal mass exceeds the thermal transfer rate generating excessive heat.
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 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.
Allow your resin to set up 3-6 hours between layers, depending on the weight of what you're adding to the next layer. Example: if adding heavy metal charms to the layer, let previous layer set up for about 6 hours so the charm doesn't push down into the layer below.

Move your artwork into a warmer spot for 24 and let it dry ( resin drying time 20-24 hours ). Sand the entiry sticky surface off with 80-grit sandpaper and pour another resin coat layer. For the smaller sticky spots, you can try resin spray, which dries very quickly leaving a clear and gloss finish.
How do you fix epoxy mistakes?
If you do encounter an uneven finish with your epoxy resin, how can go about fixing it? A good rule to follow is to mix a little bit more epoxy than you need, ensuring you cover your surface completely. So, if your epoxy has already cured properly, you will need to sand down the surface and apply a second coat.
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.
You CAN get rid of bubbles after your resin has dried.
Simply sand down the entire surface of your piece with coarse sandpaper, making sure you sand out the bubbles completely. Wipe away the sanding dust with damp paper towel, repeating as often as needed until the surface is clear of sanding residue.
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.

Epoxy thicknesses can range from . 2 – 3 mils to 250 mils (1/4”) or thicker, depending on the application. The thinner epoxy floorings are typically used for new concrete or concrete that is in decent shape and does not need a lot of repair work.
If, after finishing a project, you're left with excess epoxy, it can be stored at cold temperatures to significantly slow or stall the curing process. It is recommended that you keep mixed epoxy stored at around 40°F for no more than a few days. Once you reheat the epoxy, the curing process can resume.
For heavy duty situations, standard epoxy floor coatings and resinous systems can be installed at thicknesses of 0.375 inches (375 mils or 3/8”) or greater. These typically incorporate various strengthening aggregates or powders, followed by application of select grout coats and topcoats.

How long does deep pour epoxy take to harden?
For best results, pour epoxy in controlled workspace at temperatures from 65°-80°F. Once epoxy is poured into mold, allow 24 hours for epoxy to gel and set in mold. Areas with low volume of epoxy will take up to 36 hours to fully cure. Increasing heat 24 hours after pouring can speed up cure time.
An uneven hardening of your epoxy resin can lead to dull, or even tacky spots. To fix an uneven epoxy finish, wait until the epoxy has dried thoroughly, and then sand it lightly with fine-grained wet sandpaper. After this, make sure to wipe down the surface, so it is entirely free of any sanding dust and other debris.

You cannot leave the sticky resin, as it will not harden after time, it will remain sticky. You will have to either throw your item away or fix the problem. In order to avoid the problem all together make sure to do the following: You must measure out your resin and hardener precisely.
If the resin is still soft or gummy after 24 hours, the typical reasons are: 1. Temperature is too low. 2.
However, if you place your workpiece in a better setting and your resin still won't cure correctly, you should add another layer of epoxy. So, does tacky epoxy ever cure? Yes, and surprisingly with little to no effort required by you.

Can you pour resin in layers?
Little Windows Brilliant Resin layers beautifully and seamlessly. You can pour thin or thick layers to add embellishment, and create dimension and 3D effects. Allow your resin to set up 3-6 hours between layers, depending on the weight of what you're adding to the next layer.
Layering in molds - allow each layer to set up for at least 3 hours before pouring next layer. Doming - you can apply your resin right after the 5 minute rest period, or let the resin thicken for up to 25-30 minutes.
Unfortunately, you cannot just add another layer on top, you will have to scrape the runny resin off. Make sure to get most of it off because if you leave any behind, this may leak into the new layer of resin. Once you are sure most of the gooey resin is gone, you can then pour a new layer of resin on to your surface.
