Features
- Extra Value 8oz Acrylic Paint Thinner Medium For Slow Drying Acrylic Paints: Retain the advantages of slow drying acrylics while applying a thinner for greater coverage, glazing effects, blending effects and numerous other techniques.
- Essential For Slow Drying Acrylics: The flexibility of slow drying acrylics allows for techniques that were only previously applicable to oil paint. Unfortunately, traditional mediums and water dilution can disable the paints ability to stay wet for longer. Our Acrylic Paint Thinner, used instead of water, helps paint retain its retardancy.
- Odorless Water Based Additive: For best results, add this acrylic thinner up to 25% dilution to slow drying acrylic paint. Designed to thin paint without impacting the effect to color value and quality.
- Thin-Bodied Retarder For Heavy Body Or Fluid Acrylic: When used with non-slow drying paint, it will slow drying time, allowing a greater variety of techniques and reduces waste from paint drying on the palette.
- Non Curdle Formula: Unlike other products on the market, our paint thinner for acrylic painting won't cause your paint to curdle. It mixes easily and consistently for an even result every time. Made In The USA!
