The Woodworker's Epoxy

FlowCast has been formulated with a simple 2:1 mix ratio and is designed for larger projects such as river tables, ocean tables, and encapsulated objects. It can be combined with Liquid or Metallic pigments to create custom colors and effects.

FlowCast is intended for pours of 13-38 mm (0.5-1.5”) per layer, with a maximum pour volume of 30 L (without the use of additional cooling). FlowCast can be worked using the same tools you have in your woodshop. 

With our ever-growing line of EcoPoxy pigments and accessories, we can support you with everything you need for your epoxy projects.

Used to Create:

  • River Tables
  • Ocean Tables
  • Encapsulated Objects
  • Decorative Art Pieces
  • Custom Furniture

Frequently Asked Questions

Can I use FlowCast® for small pours?

Used in low volumes, FlowCast cures extremely slowly. Product cure times vary depending on the volume used. For smaller castings, such as serving trays or coasters, we recommend that you use FlowCast SPR.

Can I do multi-layer pours?

Yes, FlowCast is suitable for multi-layer pours. Additional layers can be poured without surface preparation when the previous layer is tacky to touch. If the previous layer is no longer tacky to touch, you will need to wait for the resin to reach sufficient hardness (approximately 72 hours), then scuff the surface with 220 grit sandpaper. Remove excess dust and debris with compressed air and wipe the surface clean with denatured or isopropyl alcohol before pouring the next layer.

Can I pour thicker than 38mm (1.5”)?

If you are planning to pour thicker than 38 mm (1.5”) and at a volume greater than 30 L, pouring in multiple layers is suggested to prevent overheating. Alternatively, you can actively cool a thicker pour with fans, but you must be prepared to constantly monitor the temperature to make sure that your project does not overheat. Note that results will vary depending on ambient temperature. When mixed in large quantities, this product can generate significant heat. Handle with care.

Do I need a seal coat? What product do you recommend?

We recommend seal coating any surfaces that will be submerged in FlowCast. Seal coats help prevent air and moisture from migrating out of submerged materials, which can cause bubbles. UVPoxy is the preferred system for seal coats as it is a faster curing resin made for applying in thin layers. Cured seal coats should be abraded and cleaned before proceeding with pours.

What products can I use to finish my FlowCast project?

For a high gloss top coat, EcoPoxy’s UVPoxy is an ideal choice. For matte to gloss finishes, use wood wax, hard wax oil, or urethanes. Any product that is intended for wood finishing is compatible with FlowCast.

Will my project yellow over time?

All epoxies yellow over time. To combat this, we formulated FlowCast with UV stabilizers. These additives absorb UV light and prevent damage to the resin. Eventually, the stabilizers will lose their effectiveness. Adding metallic or liquid pigments to FlowCast will help it resist yellowing better than if it is left transparent. Completed projects should not be kept outdoors.

Mixing & Application Instructions

Mixing

In a clean, dry container combine (by volume) 2 parts resin with 1 part hardener and mix thoroughly for 4-5 minutes. Add Liquid or Metallic pigments as desired and mix until evenly dispersed.

Application

Working area should be clean, dry, and free of dust. FlowCast can be poured at 13-38mm (0.5-1.5”) per layer. FlowCast will not shrink while curing under normal conditions. However, it may slowly fill cracks and voids in live edge wood pieces, causing the resin level to drop. Be prepared to add more epoxy as needed.

Epoxy releases heat when curing. For pours of 30L or more, multiple thinner pours may be necessary to prevent overheating. Fans blowing across the curing epoxy may also be used to help dissipate heat. For best adhesion between layers, wait until the first layer is tacky to touch before pouring a second layer. If the previous layer is no longer tacky, sand with 220 grit sandpaper and wipe down before pouring another layer.

Premium FlowCast Features

Ideal for Thick Pours

With the ability to cast from ½” to 1½” thick pours, FlowCast is perfect for river tables, ocean tables, and any other deep pour or large casting application.

Bubble-Free Castings

FlowCast’s low viscosity provides excellent air release allowing trapped air to rise to the surface, significantly reducing bubbles in the cured casting.

Outstanding Transparency

FlowCast cures to a transparent water-clear finish. It can also be combined with Liquid and Metallic pigments to create custom colors and effects.

Low Heat Build Up

FlowCast cures slowly with low heat build up resulting in less warping and cracking in your epoxy project.
