What Do You Mean By “Deep Pour” Epoxy Resins?
“Deep pour” epoxy resin is specially formulated resin designed to cure at a thickness of up to 2 inches or more in a single pour.
Deep-pour resin has a slower curing time and generates less heat, allowing them to be poured in thick multiple layers without issue.
This makes them ideal for creating river tables, large casting projects, and other applications that require a thick, clear, and smooth finish.
Other Resin Types
Coating Resin
This can be used to cover things up and protect them. It can make the surface look really shiny and smooth.
Coating epoxy resin can help keep the thing you’re covering safe from scratches and other damage. It’s especially useful for covering concrete floors to make them look nice and shiny.
UV Resin
It only has one part, and it needs a special light called a UV light to make it harden. This material dries really fast once you shine the light on it, which gives you more time to work with it. But it only lasts for six months, so you have to use it up quickly.
Alkyl Resins
Polyhydric alcohols and polybasic acids are the key ingredients in producing these materials.
They possess excellent thermal resistance and are efficient conductors of electricity, which makes them ideal for insulation, electronic device production, and paint manufacturing.
Acrylic Resins
These items are created from acrylic acids and possess remarkable tensile strength while also being resistant to UV radiation.
Silicone Resins
Due to their ability to repel water and excellent thermal stability, these materials are frequently used to produce laminations, rubber, coatings, paints, and other products that are water-resistant.
Polycarbonate Resins
These materials have a high refractive index, which makes them valuable for producing photographic films, helmets, lenses, and other similar items.
Polyester Resin
Characterized by flexibility and high heat resistance, these materials are cost-effective and widely utilized in various industries such as lamination, construction, fishing rod production, decorations, coatings, and even for manufacturing bottles. (More about heat-resistant epoxy here!)
Polyurethane Resin
This is used in cars and to protect electronics. When you heat it up, it becomes really tough and strong and can even handle high temperatures. It hardens quickly, sticks really well, and can flow easily, which makes it great for making molds.
Why is Epoxy Resin Ideal for Thick Pours?
Epoxy resin is a popular choice for broad pours for several reasons. When we talk about thick pour, we mean pouring the resin in layers that are at least 1/4 inch or more. Here are some reasons why epoxies are ideal for thick, deep pours:
- Epoxy resin generates low amounts of heat during curing, which means it can be used without cracking or melting.
- It is self-leveling, which spreads out and settles evenly over the surface. This helps prevent air bubbles from getting trapped in the resin.
- Epoxies have a higher viscosity than other types of resin, and it is less likely to run or drip when poured in thick layers.
- Once cured, epoxies have high strength and durability and are ideal for use in high-traffic areas or in objects that need to be sturdy.
- It has a clear finish that enhances the beauty of wood, stones, and other materials.
- Epoxy resin is UV resistant and heat resistant, so it can be used outdoors without yellowing or fading.
- It is also resistant to chemicals, making it ideal for use in laboratories or where chemicals are commonly used.
Deep Pour Resin vs Tabletop Resin: What are the Differences?
Deep pour resin and tabletop resin are two types of resin epoxies that differ in their properties and applications.
Deep-pour resin is designed to be poured in thick layers of up to 2-4 inches, and it takes longer to cure, usually 24 to 48 hours. Deep pour has a low viscosity, which allows it to flow more easily and remove air bubbles.
Deep-pour resin is commonly used for creating river tables, deep resin molds, and other similar epoxy projects that require a significant amount of resin to be poured at once.
On the other hand, the tabletop resin is intended for applications where a thinner, more consistent layer is required, such as coating surfaces like river tables, countertops, and bar tops.
It cures relatively quickly, usually in 24 hours or less, and has a higher viscosity than deep-pour resin, which allows it to stay in place and not flow over the edges.
Epoxy Resin vs Casting Resin: How Do They Differ?
It is not appropriate to use the terms “casting epoxy” and “epoxy resin” interchangeably, as they differ in their intended use.
Epoxy resin [1] is typically used for bonding, coating, or sealing surfaces, while casting epoxy resin has low viscosity specifically formulated for deep pours, such as in creating river jewelry or river tables and for encapsulating objects in molds.
Epoxy Resins for Thick Pours Buyer’s Guide
UV Damage
Most epoxy resins are highly susceptible to UV deterioration. To ensure longevity, we recommend using a non-yellowing formula and acquiring a UV-resistant topcoat in addition to the preferred finish.
Durability
If your project will be subjected to wear and tear or harsh conditions. Buy epoxy resin that is designed to be strong and durable, with good resistance to impact, scratches, and chemical damage.
Bubbling
Bubbling can be a common issue when working with epoxy resin, especially during the curing process of a low-viscosity epoxy resin. Look for a resin that is specifically formulated to minimize bubbling and ensure a smooth, even finish.
Some resins may require additional techniques, such as using a heat gun or torch, to eliminate bubbles. Be sure to carefully follow the manufacturer’s instructions and take steps to prevent bubbling during the pouring and curing process.
Water
If your project will be exposed to water or moisture, it’s important to choose an epoxy that won’t soften or break down when exposed to moisture.
This is particularly important for projects such as countertops, tables, and other surfaces that will be frequently exposed to water.
Abrasion and Scratch
If your project is subjected to frequent use or heavy traffic, look for the best epoxy resins specifically designed to resist abrasion and scratching.
This will help ensure your project maintains its appearance and functionality over time, even with regular wear and tear.
Mixing Ratio
When you are new to epoxy pouring, the mixing ratio of the epoxy resin and hardener is a critical factor that affects the performance and properties of the cured resin.
When buying epoxy resin, look for a resin with a mixing ratio. It’s important to carefully follow the epoxy resin store instructions and measure the components accurately to ensure a proper cure and optimal resin performance.
Food-Safe Capability and Safety
If you want to use epoxy resin on a tabletop that you eat on, you need to make sure that it follows all the rules set by the FDA. You should look for a formula that is safe and doesn’t have any dangerous chemicals.
However, even if you choose an epoxy resin-safe formula, it’s important not to use it indoors instead, use it in a place with good airflow. You might also need to wear a mask, glasses, and gloves to be extra safe.
Application and How Much Resin You Need
Consider the application method and the amount of resin you will need for your project. Some epoxies may require a specific application method, such as using a brush or roller, while others can be poured directly onto the surface. But what kind of surface does epoxy not stick to? Find out next!
Working and Curing Time
This can affect your ability to achieve the desired result. Some epoxy mixtures may have a longer working time, which can benefit complex projects, while others may have a shorter curing time, which can help reduce the overall project time.
Self-Leveling
When looking for the best epoxy resin for thick pours, look for ones with self-leveling properties because it can make your project so much easier. You can use it to fill in holes, cover up cracks, and smooth out bumps on the wood surface.
The best part is that you don’t need to worry about leaving brush marks or other mistakes because you don’t need a paintbrush or roller.
Resin Quality
Look for a resin that is manufactured to high standards and has been tested for quality and consistency. Some manufacturers may offer certifications or third-party testing to ensure their epoxy resin products meet industry standards.
Things To Consider Before Starting The Project
Make sure that any materials you plan to use with epoxy resin are chemically compatible. To determine which materials are safe to mix with the resin, you can conduct research online or consult the manufacturer’s instructions.
Ensure you use silicon molds because the resin heats up when mixed with the hardener and starts to harden. Silicon can handle heat well and is often used to make molds.
Don’t forget to protect yourself by wearing gloves, an apron or coat, safety goggles, and shoes when working with epoxy resin.
The fumes from the resin can be strong, so it’s important to work in a well-ventilated room with windows and doors open.
Are All Epoxy Resins Good For DIY Arts & Crafts?
Not all epoxy resins are good for DIY art and crafts. Some epoxy resins are specifically designed for industrial use, while others are formulated for specific applications, such as coating or casting.
How to Make Floral Coasters Using Epoxy Resins
- You will need epoxy resin, a silicone coaster mold, dried flowers, and a mixing cup.
- Select your favorite dried flowers and trim them to the appropriate size for your coaster mold. You can mix and match different types of flowers for a unique look.
- Follow the manufacturer’s instructions to mix the resin and hardener in a mixing cup. Make sure to mix the components thoroughly to ensure a proper cure.
- Pour a small amount of the epoxy resin into the bottom of the coaster mold, covering the entire surface.
- Arrange the dried flowers on top of the resin, pressing them down gently to ensure they are fully submerged.
- Pour the remaining resin over the flowers, covering them completely.
- Use a toothpick or a heat gun to remove any bubbles that may have formed in the resin.
- Let the resin cure for the recommended time; usually, epoxy resin cures for 24-48 hours in a dust-free area.
- Once the resin has fully cured, remove the coasters from the mold by gently bending it to release the coasters.
Using Deep Pour Resin Effectively in 4 Steps
Step #1: Prepare Your Workspace, and Your Workpiece
Prepare your workspace by covering it with a tarp or old newspaper to prevent resin from spilling or splattering on your furnishings.
Ensure your workspace is well-ventilated, and wear appropriate personal protective gear such as a face mask and gloves.
Preparing your workspace and workpiece is the most important step when working with epoxies to prevent contamination or poor adhesion.
Step #2: Ready Your Chosen Resin
Mixing deep pour resin can be tricky, but with a 2:1 ratio of resin to hardener, it’s important to use twice as much resin as a hardener.
The change in ratios makes deep-pour resin cure slower but allows for more resin to be poured before it becomes too thick. To mix, pour the hardener and resin into a separate cup based on how much you need.
Step #3: Now, Pour Your Resin
Once you have mixed your resin and hardener, it’s time to pour the solution into the coaster molds. To pour the resin properly, slowly pour a small amount of resin into the center of the mold.
Then, use an ice cream stick or a toothpick to spread the resin evenly across the mold. Make sure that the resin covers the entire surface area of the mold and is distributed evenly.
Do not pour too much resin simultaneously, as it may overflow and create a mess. Instead, pour in small amounts and continue spreading until the mold is covered.
Be sure to work carefully and take your time while pouring the resin to ensure a smooth and even finish.
How to Prevent Bubbles While Working With Epoxy Resin
To prevent bubbles from forming when pouring resin, use a mold or form made from material that does not contain air pockets, such as silicone.
Choose a resin with a thin viscosity and pour it slowly at room temperature, around 75 degrees Fahrenheit. Warm the resin and hardener in warm water before mixing them, and mix slowly to avoid introducing air.
If bubbles develop, apply heat with a heat gun or propane torch to bring them to the surface and use a toothpick or drinking straw to remove them.

Step #4: Curing and Finishing Your Epoxy
To properly cure your epoxy, be patient and wait until it is fully cured, which may take up to a week. To finish your project, use sandpaper to remove any excess and achieve a polished finish.
For large, deep pours, a planer can be used. Apply a finishing coat with mineral oil for food contact or polyurethane/wax oil for non-food contact.
Applying Deep Casting Resin & Surface Pour Resin
1. Prepare the surface: Make sure the surface is clean, dry, and level. If casting in a mold, apply a mold release agent to prevent the resin from sticking to the mold.
2. Mix the resin: Follow the instructions on the resin packaging to mix the resin and hardener in the correct ratio. Use a slow and steady stirring motion to avoid introducing air bubbles into the epoxy mixture.
3. Pour the resin: Slowly pour the resin into the mold or void. Start from one corner and work across the surface to ensure even coverage. If necessary, use a spatula or brush to spread the resin.
4. Wait for the resin to cure: Deep clear casting resin and surface pour resin can take several hours to cure completely, depending on the thickness of the layer. Check the resin packaging for the recommended curing time.
Tips & Safety Precautions While Using Epoxy Resins
Work with Good Ventilation
It’s important to ensure good ventilation in your workspace when working with epoxy to prevent exposure to harmful fumes.
You can achieve this by creating cross-ventilation in the room, such as using a ceiling fan to draw the fumes away or opening windows.
Use Gloves and Safety Glasses
Wearing gloves can help to protect your skin from touching the hardener and resin. It’s best to use nitrile gloves because they won’t make a reaction.
Sometimes, latex gloves may not work well and can stop the resin from drying properly.
Use of a Respirator and Apron
When working with many epoxy or other chemicals, it’s important to wear a respirator to prevent breathing in harmful fumes.
Even if the product’s safety data sheet says a respirator isn’t needed, it’s still a good idea to wear one for safety.
It’s a good idea to wear also an apron when working with epoxy because spills can happen and ruin your clothes. A plastic apron is a cheap and easy way to protect your clothing.
Must-Read: Is Epoxy Resin Food-Safe?
Mix Your Epoxy Properly Using the Correct Ratio
Mixing your epoxy is an important part of the process. You need to follow the instructions carefully so that your epoxy projects turn out the way you want them to.
Each product may have a different mixing ratio of resin and hardener, such as 1:1 or 2:1, and you can find this information on the packaging.
Using an epoxy calculator can be helpful in figuring out the correct ratio. You should measure the resin and hardener by volume using a measuring cup, not by weight, to get the ratio right.
Observe Temperature & Humidity
If you mix the resin and hardener at temperatures lower than 68 degrees Fahrenheit, the curing method will slow down, and the resin might crystalize.
On the other hand, mixing at temperatures above 68 degrees Fahrenheit will speed up the curing method but reduce your working time.
Warm Your Epoxy Resin
Before using your resin, it’s important to let it sit at room temperature, around 71 degrees Fahrenheit, for 12 hours. If you need to speed up the process, you can also warm up the resin by placing the container in warm water.
Add Colors to Your Resin
It’s important to make sure that the liquid pigments, color paste, or alcohol ink you use are compatible with your specific epoxy resin.
Be Careful While Mixing
It’s important to mix your hardener and resin thoroughly, or else your epoxy might not cure properly, and your material will be soft.
We do not recommend mixing different brands of hardener and resin together, as it can cause a chemical reaction that produces excessive heat.
Water & Epoxy Resins
When working with epoxy resin, it’s important to keep all of your equipment and tools completely dry because moisture or water doesn’t mix well with liquid pigments resin.
