What’s Included in Our Range

Eco-Friendly Casting Powder & Fine Cements: Specially milled for casting; mixes smoothly without clumps, flows effortlessly into intricate molds, and cures with a silky-smooth, porcelain-like stone texture.
Non-Toxic Protective Sealers: Water-resistant, stain-proof acrylic and penetrative sealers designed to protect concrete candle jars from hot wax absorption, soot, and daily moisture.
Rich Liquid Pigments & Acrylic Paints: High-load color concentrates engineered specifically for tinting raw cement mixes or hand-painting finished décor with vibrant, fade-resistant color.
Precision Brushes, Sponges & Palette Knives: High-density craft sponges and fine bristle brushes for applying even coats of sealer, texturing surfaces, and adding artistic marble or metallic highlights.
Mixing Tools & Sanding Pads: Durable stainless steel scoops, scrapers, and multi-grit waterproof sanding pads to level vessel bases and polish surfaces to perfection.

Key Advantages

Silky Smooth Finish: Formulated to eliminate unsightly pinholes, air voids, and chalky residue.
Wax & Heat Safe: Properly sealed vessels withstand heat and prevent candle fragrance oil seepage.
Fast Curing & Easy to Demold: Eco casting compounds reach demolding strength rapidly, speeding up your production workflow.
Versatile Applications: Perfect for Jesmonite-style resin composite art, terrazzo effects, white and grey cement casting, and plaster crafts.

Recommended Crafting Workflow

Mix: Combine eco casting powder or cement with the recommended ratio of water/liquid binder. Add mineral pigments drop by drop to achieve your desired shade or marbling effect.
Pour & Degas: Pour slowly into your silicone mold and tap firmly on your tabletop to release trapped air pockets.
Demold & Sand: Once set, gently demold your piece. Smooth down the base using fine-grit sandpaper for a balanced, level sit.
Seal & Protect: Apply 1–2 thin, even coats of SL Shopping Sealer using a soft brush or sponge, allowing each coat to dry thoroughly to lock out moisture and wax.
