The Ultimate Guide to Mixing Epoxy (And Setting Up Your Space for Perfect Pours)

Get crystal-clear, bubble-free, professional results — every time.

So you’ve got your resin and hardener… now what?
Whether you’re crafting a tumbler, making a river table, or pouring your first tray, how you mix your epoxy matters just as much as what you’re making. And your room setup? That’s half the battle.

This guide covers everything you need to know about mixing epoxy and prepping your space so you get smooth, strong, crystal-clear results with no yellowing, bubbles, or fails.

Step 1: Set the Right Room Conditions
Before you even open your bottles, let’s get your environment ready.

Ideal Room Conditions for Mixing Epoxy:

• Temperature: 72°F–77°F (room temperature)

• Humidity: Below 40% (30%–35% is optimal)

• Airflow: Gentle air circulation — no fans blowing directly on your pour

• Lighting: Natural light or white LEDs (no heat lamps or colored lights)

Avoid working in garages or basements without humidity control — moisture will wreck your finish.

Pro Tip: Use a dehumidifier if you’re in a humid area and store resin in a climate-controlled space (not the garage shelf).

Step 2: Warm Your Resin for Better Flow
Cold resin = thick resin = more bubbles.
If your bottles are cool to the touch, place them (sealed) in a warm water bath for 10–15 minutes before mixing.
Target temperature: approximately 75°F
Do not microwave epoxy — ever.

Step 3: Mix the Right Ratio
Most epoxy resins (including Artistry Epoxy) are mixed 1:1 by volume.
That means:

• 8 oz of Part A = 8 oz of Part B

• Don’t measure by weight unless your instructions say so

• Don’t “eyeball it” — be precise

Use silicone measuring cups or graduated plastic mixing cups for best results.

Step 4: Mix Slowly and in Two Cups
This is where a lot of people mess up.
Double-cup mixing method:

• Pour equal parts into your first cup

• Mix slowly for 1 full minute — scrape the sides and bottom

• Transfer to a clean second cup

• Mix for 1 more full minute

This prevents streaky resin, reduces bubbles, and guarantees a full chemical reaction.
Pro Tip: Use silicone stir sticks or tongue depressors. Avoid whisks or high-speed tools — they trap air.

Step 5: Pour and Pop Bubbles (Without Overheating)
Once mixed, pour immediately into your mold or surface.

• Use a heat gun or torch 6–8 inches away to pop surface bubbles

• Don’t overheat — this can scorch or cause “flash cure”

• Pour in layers if needed (especially for deep molds)

Artistry Epoxy includes a built-in bubble release, so torching should be minimal.

Optional: Additives, Pigments, or Color Correct+
Add mica powder, glitter, alcohol inks, or Color Correct+ UV+ Dye after your epoxy is fully mixed.

• Stir gently

• Start small and build up — a little goes a long way

Common Mixing Mistakes to Avoid

• Mixing too fast = bubbles galore

• Pouring Part A and Part B into separate cups, then combining

• Wrong ratio = soft, sticky, or failed cure

• Pouring in a humid room = hazy, cloudy finish

• Using cold resin = slow cure and poor clarity

• Not scraping the sides = unmixed epoxy = tacky spots

Final Tips: Clean Tools, Clean Results

• Always use clean cups and tools

• Wipe down work surfaces

• Wear gloves (resin is a skin irritant)

• Use a silicone mat under your project for easy cleanup
