Buying Guide: Key Purchase Considerations

What type of pouring technique will you use most often? If you plan to experiment with multiple methods (dirty pours, direct pours, etc.), choose a versatile medium that dries with a reliable finish and manageable flow. For large projects or classrooms, a bulk option with easy dispensing can save time. If you want a glossy, cell-rich look, select a gloss medium designed to enhance cells and clarity. For beginners, a clear bottle with a simple 1:1 mix ratio helps establish consistent results quickly.

How does finish affect your project? Satin finishes are more forgiving on color shifts, while gloss finishes offer bright, vibrant results with high contrast. Consider the surface you’ll paint on, as some media perform better on canvas, wood, or panels. If durability or resistance to cracking is a priority, look for media formulated to minimize cracking and fading during drying.

What about compatibility with acrylic paints? Most pouring mediums are designed to work with acrylics, but textures and pigments can react differently. Start with small batches to confirm flow and color interactions before committing to large pours. For color-rich pieces, test color separation and cell formation on swatches first.
