Selecting the best epoxy for thick pours can be confusing given the wide array of thick pour epoxy resin lineup in the market right now. So, what epoxy resin should you go for, and what factors should you pay attention to? How thick can you pour epoxy resin? What are some of the tips you should be aware of when handling epoxy resin for thick pours? How long does an epoxy resin for deep pour take to cure? Kindly read the article below for the full insight.
WHAT ARE THICK POURS?
Thick pours are design situations usually relatively deep depressions in surfaces (metal, wood, plastic) that warrant filling by another material. One of the best materials that you can use to fill such depressions is epoxy resin. Thickness is specific to depressions for example, we can have 1”, 2” or 4” depressions that would require as much epoxy resin height to fill by multiplying the thickness of the depression.

The instructions for this epoxy resin advocate for 2” maximum pour when dealing with small epoxy molds and 1” when dealing with large casts. The epoxy has a self-leveling capability.
The epoxy resin to hardener ratio is 3:1, which is easy to measure out.
Since the epoxy resin requires a long working time, the resulting surfaces are tough, durable, and waterproof, being perfect for beginners and pros alike.
The epoxy resin produces an ultra-clear gloss that can be manipulated by adding solvents to enhance appearance for example, mica powders, alcoholic dyes, and color pigments.
This epoxy is eco-friendly and only produces low odor due to its low VOC formulation. Therefore, the epoxy is ideal for spaces with relatively less ventilation for example, underground garages, shops, or any indoor use. When the surface cures, the result is a piece free from BPA (Bisphenol A) that is safe for drinks and food.
Another advantage, as with all other epoxy resins, for thick pours, is the ability to pour deeply at a go.

FAQ Frequently Asked Questions
HOW THICK CAN YOU POUR EPOXY RESIN?
Each epoxy resin has a maximum thickness imposed by the manufacturer, beyond which you need to stop the pour, wait for the surface to cure, and then proceed to add consecutive layers onto the surface.
Therefore you can only pour epoxy resin as thick as advised by the manufacturer in a single pour.
However, you have a limitless possible thickness if you are working in phases since after reaching the maximum height of a single pour, you can add as many consecutive layers as you want.
This article considers an epoxy resin for thick pour to have at least 1” maximum pour on a single application.

SELECTING THE BEST EPOXY RESIN FOR THICK POURS – Buying Guide
There are several factors that we need to pay close attention to when selecting the best epoxy resin for thick pours
1• MAXIMUM POUR THICKNESS PER LAYER
If you are in search of the best epoxy resin for thick pours, then you are probably looking at epoxy resin with over 1” in the maximum thickness per layer. You could be looking for this property to ensure you fill your deep void as quickly as possible without having to pour many layers.
You do not have to pour 1/8 inch of epoxy and wait for 24 hours to apply a consecutive layer. This process could take you close to 8 days.
2• WORKING TIME
With a long working time, a user is assured of complete cures that allow functional use. The result surfaces are tough and durable without the loss of bond integrity at layer boundaries. However, slow setting epoxy resins require patience and might require simulations to assess the quality of curing.
3• BONUS FEATURES
Working with epoxy resin in the current waves of Green Energy, it is critical to ensure you not only use an ideal epoxy for your specific project but that it is also safe for human use during and after the application.
Having the ability to add pigments to epoxy allows users to explore resin art by making patterns that make the limitless list of possible thick pour epoxy resin projects.
Often when dealing with thick pours, you end up with large surface areas exposed. If these surfaces are exposed to UV light, then the degree of yellowing significantly increases, and hence an epoxy with UV resistance properties is an advantage.
TIPS TO REMEMBER WHEN USING THE BEST EPOXY RESIN FOR THICK POURS
If one is working with an epoxy resin with a rapid pot life, then it is beneficial to work in phases. Although working in phases involves extra steps that increase operation time and energy, phases allow the user to form a tougher, more durable, less susceptible to yellowing, more aesthetically appealing (less unwanted waves on the surface due to shrinkage) resulting surface than could have been achieved if the entire mass of epoxy was poured all at once.
When working in phases, it is critical to ensure the surface of the previously poured layer is cooled to around 22˚C since any temperature higher than this figure positively catalyzes the curing of the next layer hence compromising the integrity of the bond between the 2 layers.
On the other hand, if one is working with an epoxy resin with a slow cure (low pot life), then one is at an advantage of pouring the epoxy all at once, being patient as the mass of epoxy resin cures slowly and finally producing a tough, durable and beautiful surface.
Be sure to work at a controlled temperature as per the manufacturer’s instruction when doing thick pours all at once due to exothermic nature of the curing reaction.
Patience is the key when waiting for the epoxy resin to cure and even more important when dealing with thick pours. As such, we often drip some of the epoxy resin for the thick pour project in one or two disposable jars where we can simulate the curing stage without having to disturb our real project. This tip will save you a lot.
ANTI-BUBBLING STRATEGIES FOR EPOXY RESIN FOR THICK POURS
Avoid vigorous stirring. Avoid using blenders or round spatulas for your stirring and instead uses a flat metallic spatula that could significantly reduce bubbles.
Beware that high viscosity epoxy resin has a higher likelihood to produce bubbles than low viscosity epoxy resin. Although this choice will be dictated by your specific project, if you have the choice of viscosity, then go for a low viscosity epoxy resin.
Thick pour epoxy resins are very important in art and craft. The list for possible thick pour projects is endless, especially coupled with the potential to add pigments to epoxy. The primary factors to watch out for are maximum pour thickness per layer and working time. In addition, there are other bonus factors that make the application of thick pours close, and that include eco-friendliness, self-leveling properties, pigment compatibility, and UV resistance. There are a few tips to remember when using the best epoxy resin for thick pours, including effective curing and anti-bubbling strategies for epoxy resin for thick pours.
