Liquid silicone shows up in a few craft and DIY projects you’ll see on this page.

• Mold making: Two-part liquid silicone pours into a container and cures into a flexible mold for resin, soap, candles, and squishy-style projects.
• Fluid art: Silicone pouring oil is a separate product that’s added to acrylic paint mixes to help create “cells” and interesting textures.
• Repairs & sealing: Clear silicone adhesives can bond or repair silicone, TPE/TPU, and other craft materials.
• Resin companion: Many crafters cast epoxy or UV resin into cured silicone molds (resin is a different material, but they’re often used together).

It helps to match the product type—mold-making rubber, pouring oil, or adhesive—to the job you’re tackling.

Silicone is the umbrella term for flexible, rubber-like polymers used in lots of products. On this page, you’ll see a few different forms:

• Liquid silicone for molds: A pourable, two-part material (Part A + Part B) that cures into silicone rubber you can demold and reuse.
• Silicone pouring oil: A non-curing liquid added to acrylic paints to encourage cell effects and interesting patterns.
• Silicone adhesives: Clear glues that cure to create a flexible bond for craft repairs and models.

So, “liquid silicone” usually refers to the uncured pourable type used for mold making, while the broader term “silicone” includes cured rubber items, oils, and adhesives. Checking each item’s intended use, mix ratio, and cure details can help you pick the right one.

In craft kits here, liquid silicone is typically a two-part, pourable material (labeled Part A and Part B). When you measure and mix those parts, it cures at room temperature into a flexible silicone rubber.

• Common traits: Often a 1:1 mix ratio, low to medium viscosity for easy pouring, and a translucent look that helps you see details.
• What it’s for: Capturing fine details to make reusable molds for resin, soap, candles, or soft squishies.
• Cure timing: Some fast-cure formulas list demold times around a few hours; full cure may take longer depending on formula and thickness.

It’s different from epoxy or UV resin—those are separate casting materials commonly poured into cured silicone molds.

Mold-making liquid silicone cures into a flexible, rubbery solid—not a hard plastic. It’s firm enough to hold detail, but stretchy enough to release casts. How it feels can vary by formula and thickness.

• Timing: Some fast formulas list demold times around 3–4 hours; full cure can take longer and depends on temperature, mix accuracy, and pour size.
• Silicone oil note: Pouring oil used in acrylic painting doesn’t cure into rubber—it’s an additive for paint effects.
• Adhesives: Clear silicone glues cure to a thin, flexible bond line.

For best results, measure Parts A and B accurately, mix thoroughly, and work at a stable room temperature. Results can vary by product and project setup.

A few specs can help you narrow it down based on your project:

• Mix ratio: 1:1 systems are beginner-friendly to measure and mix.
• Cure speed: Fast-cure is great for quick turnarounds; standard cure can offer a longer working time.
• Viscosity: Thinner silicone flows into fine details; thicker options can reduce run-off.
• Flexibility: Softer rubbers release complex shapes more easily; firmer rubbers support straighter edges.
• Clarity: Translucent formulas help you see placement and trapped bubbles.
• Volume: Choose a kit size that comfortably covers your piece.
