BB-CP1 Plaster Casting Powder DIY Decor Powder

Casting Resin Kit is a water-based casting powder for making handmade decor and molded craft pieces. It is easy to mix, pour, and demold, making it a practical material for small-batch makers, candle businesses, and DIY craft projects.

This is not epoxy resin. It does not require resin hardener or UV curing. Final results depend on your water ratio, mold type, pigment, mixing method, room temperature, and curing time.

• Water-based casting material
• Easy powder-and-water mixing process
• Good for silicone molds and small decor pieces
• Creates a smooth matte stone-like finish
• Can be colored with compatible pigments
• Beginner-friendly for small craft projects

1. Prepare a clean silicone mold.
2. Measure casting powder and water by weight.
3. Add powder into water slowly.
4. Mix until the material becomes smooth and pourable.
5. Tap the cup or mold gently to help release air bubbles.
6. Pour into the mold slowly.
7. Allow the piece to set before demolding.
8. Let the finished piece dry fully before sealing, painting, or selling.

For cleaner results, measure by weight instead of guessing by volume. Mix slowly and scrape the sides of the cup so dry powder does not remain unmixed.

• Thicker mix: Usually creates stronger pieces but may trap more bubbles.
• Thinner mix: Pours more easily but may reduce strength if too much water is used.
• Pigment: Add a small amount first and test color strength before scaling.
• Air bubbles: Tap the mold gently after pouring.
• Marble effect: Swirl pigment lightly instead of fully mixing.

• Candle vessels: Test for small candle jars, holders, and decorative vessels.
• Trays: Good for jewelry trays, vanity trays, and small display plates.
• Home decor: Use for ornaments, sculptures, and decorative objects.
• Silicone molds: Works best with flexible molds for easier demolding.
• Small-batch products: Good for makers testing handmade decor lines.

Most casting problems come from incorrect water ratio, fast mixing, trapped bubbles, weak molds, or demolding too early.

• Too many bubbles: Mix more slowly and tap the mold after pouring.
• Piece breaks easily: Use less water, cure longer, or test a thicker design.
• Surface looks powdery: Let the piece dry longer before sealing or handling.
• Hard to demold: Use a flexible silicone mold and wait longer before removing.
• Color looks uneven: Mix pigment more thoroughly or test a different pigment type.
• Edges chip: Avoid thin edges and demold more slowly.

If using finished pieces as candle vessels, sealing and heat testing are required. Casting materials can absorb oil, fragrance, dye, or moisture if left unsealed.

• Let pieces dry completely before sealing.
• Use a compatible sealer for decor or candle vessel testing.
• Test for leaks before pouring candle wax.
• Burn test every candle vessel design before selling.
• Do not use cracked, thin, or damaged vessels for candles.

Store casting powder in a cool, dry place away from moisture, humidity, direct sunlight, and strong odors.

Keep the bag sealed when not in use. Moisture exposure can cause clumping or affect the final casting result.

Is this epoxy resin?
No. This is a water-based casting material. It mixes with water and does not use epoxy hardener or UV curing.

What is this kit best used for?
It is best used for silicone mold casting, trays, decor pieces, ornaments, holders, candle vessels, and small craft projects.

Can beginners use it?
Yes. It is beginner-friendly, but measuring, mixing, bubbles, and demolding still need practice.

Can I color it?
Yes. Test compatible pigments in small batches first. Too much pigment can affect strength and surface finish.

Can I use it for candle jars?
Yes, but only after proper sealing, leak testing, and burn testing. Do not assume an unsealed casting piece is ready for candle wax.

Do I need to seal finished pieces?
For decor, sealing is optional depending on the look you want. For candle vessels, trays exposed to oils, or pieces that may touch water, sealing is strongly recommended.

Why did my piece crack?
Cracking can happen from too much water, thin walls, demolding too early, uneven drying, or weak mold design.

Why are there bubbles?
Bubbles usually come from fast mixing or trapped air in the mold. Mix slowly and tap the mold after pouring.

How long should I wait before demolding?
Demold time depends on mold size, thickness, water ratio, and room temperature. Small pieces can set faster; thicker pieces need more time.

Can I sand or paint finished pieces?
Yes. Let the piece dry fully first, then sand or paint as needed. Sealing after painting can help protect the finish.
