How to Prepare for Resin: A Step-by-Step Guide

Working with resin can be incredibly rewarding, but getting a flawless finish starts before you even pour a single drop. In this guide, we’ll take you through the essential steps to prepare your workspace, mold, and resin so your projects come out smooth, bubble-free, and professional-looking.

Step 1: Choose a Stable, Level Surface
A level surface is key to a smooth resin pour

A level surface is the foundation of a perfect resin project. If your table or workspace is uneven, resin can pool in certain areas, leaving one side thicker than the other.

Tips:

  • Use a flat, stable table.
  • Place protective sheets or parchment paper under your mold to catch any drips.
  • Check with a spirit level if possible, especially for larger projects.
Step 2: Clean Your Mold Thoroughly
Cleaning your mold ensures a flawless finish

Even the tiniest dust or fingerprints can show up in resin. Cleaning your mold properly ensures a crystal-clear finish.

Steps:

  1. Wipe the mold with a lint-free cloth.
  2. Use cellotape or masking tape to lift away tiny particles.
  3. Ensure the mold is completely dry and free from oil or residue.

💡 Pro Tip: Silicone molds can be wiped with isopropyl alcohol for extra cleanliness, but let them dry completely before pouring.

Step 3: Wear Gloves and Prepare Safety Gear
Protect your hands before working with resin

Before handling resin, protect yourself and your workspace. Safety gear helps prevent skin irritation and keeps your environment clean.

Steps:

  1. Put on nitrile gloves to protect your hands. (Avoid latex gloves—they can react with resin.)
  2. Wear a mask if you’re working in a small or poorly ventilated area.
  3. Keep paper towels or cleaning wipes nearby for spills.
  4. Cover your workspace with a plastic sheet or silicone mat for easy cleanup.

💡 Pro Tip: Always work in a well-ventilated area and keep food and drinks away from your workspace.

Step 4: Measure Resin Accurately
Measure resin and hardener precisely according to instruction

Resin comes in two parts: Part A (resin) and Part B (hardener). Mixing them in the correct ratio is crucial for proper curing.

Steps:

  1. Check the manufacturer’s instructions for the exact ratio (e.g., 1:1 or 2:1).
  2. Use separate measuring cups for Part A and Part B.
  3. Pour carefully to avoid spills and maintain precision.

💡 Pro Tip: Always measure by volume, not weight, unless the instructions specify otherwise.

Step 5: Mix Resin Thoroughly
Mix gently but completely, scraping sides and bottom

Mixing ensures that Part A and Part B react properly. Improper mixing is a common cause of sticky or uncured resin.

Steps:

  1. Pour Part B into Part A.
  2. Stir gently but thoroughly for at least 2–3 minutes.
  3. Scrape the sides and bottom of your mixing cup to make sure everything combines.

💡 Pro Tip: Mix slowly to reduce bubbles, but don’t rush—thorough mixing is essential.

Step 6: Optional Workspace Preparations
  • Remove dust from the air or cover your project with a box or plastic sheet.
  • Have a heat gun or torch ready to remove surface bubbles after pouring.
  • Double-check your workspace lighting so you can see bubbles and details clearly.
Conclusion

Preparation is the key to perfect resin projects. Spending a little extra time on leveling, cleaning, and mixing ensures your pieces come out clear, smooth, and professional every time.
