To use pigment paste in resin, add a small amount—roughly a fingernail's worth—per ounce of epoxy resin and thoroughly mix until the color is completely distributed. This colored mixture is then ready to pour and use for your resin project.
Here's a more detailed breakdown:
- Measure the Resin and Hardener: First, accurately measure the resin and hardener according to the manufacturer's instructions for your chosen resin. This is crucial for proper curing.
- Prepare the Pigment Paste: Have your pigment paste ready. Remember that a little goes a long way.
- Add the Pigment Paste: Start by adding a small amount of pigment paste to the mixed resin and hardener. A good starting point is about a fingernail-sized amount per ounce of resin.
- Mix Thoroughly: This is the most important step. Stir slowly and deliberately to avoid creating air bubbles. Ensure the pigment is completely dispersed throughout the resin. Scrape the sides and bottom of your mixing container to ensure even distribution.
- Adjust Color as Needed: If the color is not intense enough, add a tiny bit more pigment paste, mixing thoroughly each time. It's easier to add more color than to try and remove it.
- Pour and Create: Once you're satisfied with the color, the resin is ready to pour into your mold or onto your surface for creating your desired effect.
Important Considerations:
- Pigment Load: Adding too much pigment can affect the curing process of the resin and may result in a sticky or uncured finish. Stick to the recommended ratio.
- Type of Resin: Pigment pastes are generally compatible with most epoxy resins, but it's always a good idea to do a small test batch first.
- Opacity: Pigment pastes come in various opacities (transparent, translucent, opaque). Choose the one that suits your desired effect.
- Safety: Always wear appropriate safety gear, such as gloves and a respirator, when working with resin and pigments. Follow the safety guidelines provided by the resin and pigment manufacturers.
