Bob Ross Liquid Clear 237ml

Bob Ross Liquid Clear is a lightweight medium designed for acrylic workflows that seek enhanced glaze results without altering the underlying paint color. This product is a clear medium intended to extend working time and deepen color richness when used in glazing layers. The formulation is designed to be compatible with standard acrylic paints, helping colors stay vibrant while maintaining the painter’s control over transparency. Use it to blend seamlessly between hues, or to build layers of depth in a controlled manner. Its user-friendly profile makes it suitable for hobbyists and professional studios alike.
Key points: transparent finish, extends blending time, and helps achieve luminous glazes. Suitable for projects where the goal is to preserve the brightness of pigments while adding dimensional depth. Always follow the manufacturer’s guidance for ratios with acrylic paints to avoid altering drying times more than intended.
Golden Acrylic Glazing Liquid Gloss

Golden’s Glazing Liquid Gloss is a slow-drying extender that increases translucency and working time for blending acrylic colors. It allows artists to create layered translucent passages, soft edges, and luminous glazes. The clear gloss finish helps colors appear more saturated without introducing an opaque layer. This medium is widely used for glazing techniques, atmospheric effects, and achieving depth in landscapes or abstract works. It’s compatible with a broad range of acrylic paints, making it a staple in studios focused on color finesse and controlled light transmission.
Considerations: it lengthens the open time, raises color vibrancy, and provides predictable glaze behavior. When used in larger quantities, test layers to anticipate changes in dry time and texture, especially on porous or primed surfaces.
U.S. Art Supply Clear Gesso Primer (16oz)

Clear gesso provides a versatile, non-white ground that preserves the surface texture and grain underneath while giving the paint a proper gripping layer. This 16-ounce premium acrylic gesso primer dries transparent and enhances blending and color vibrancy. It allows underlying surfaces to show through, which is useful for mixed-media pieces or when artists want to maintain the character of the canvas or board. The formula aims to balance surface preparation with minimal color shift, helping colors sit true to their intent.
Use cases include priming canvases, wood panels, or other supports before applying acrylics or oils. It’s a good alternative to traditional white gesso when the artist wants a more natural-toned base while still achieving adequate tooth for paint adhesion.
Nicpro Gloss Varnish for Acrylic Painting

Nicpro Gloss Varnish is a high-gloss, non-yellowing protective finish for acrylic artworks. It forms a clear, flexible seal that enhances color depth and provides durable surface protection. The water-based formula dries quickly and is non-toxic, making it suitable for studios with family-safe considerations. The varnish is designed to be non-tacky when dry, preserving brush marks and the integrity of the underlying paint layer. It’s a practical option for artists seeking a bright, final glossy surface while maintaining color integrity over time.
Important notes: check the drying time for optimal layering and ensure adequate ventilation during application. Apply in thin, even coats to minimize visible brush strokes and achieve a smooth final appearance.
Falling in Art Clear Gel Acrylic Medium

Falling in Art Clear Gel is a transparent gel medium designed to extend, build texture, and retain brushwork in acrylic paintings. The 500ml tub offers a thick, creamy consistency that remains translucent when wet and dries clear. It adds impasto potential, helping artists create peaks, ridges, and tactile surfaces without dulling color vibrancy. The gel also acts as a flexible binder and can be used in mixed-media applications, where texture and gloss coexist with color clarity.
Practical uses include layering for texture, extending paint films to achieve deeper dimensional effects, and bonding lightweight inclusions for mixed-media pieces. This medium is non-toxic and suitable for a range of acrylic applications, from traditional painting to experimental works.
Buying Guide: Key Purchase Considerations
- Finish and translucency: For glazing and depth, prioritize glazing liquids or liquid clear mediums that preserve color brightness and allow light to pass through thin layers.
- Drying time and open working time: Slow-drying glazing mediums enable longer blending, while quick-dry varnishes suit final coatings. Test on a sample surface to gauge performance with your technique.
- Surface compatibility: Gesso primers should be chosen based on whether you want to show underlying surface texture or achieve a smooth, even ground. Consider whether you’ll paint on canvas, wood, or mixed media substrates.
- Durability and protection: Varnishes and sealers protect artwork from dust, UV exposure, and yellowing. Non-yellowing, water-based options are generally safer for indoor spaces and education settings.
- Texture and impasto needs: Gel mediums are ideal for extending color volume and maintaining brush marks, enabling pronounced texture without compromising clarity.
- Toxicity and safety: Opt for non-toxic formulations when possible, especially for classrooms or home studios. Verify ventilation requirements during application and curing.
- Brand ecosystem: If you already use a brand’s colors, consider whether their glazing liquids or varnishes are designed to be chemically compatible with your existing paints to avoid issues with drying or color shifts.
When building a painting workflow, select a mix of products that align with your goals: glazing for depth, primer for surface preparation, and varnish for longevity. Testing on a small sample panel can help you evaluate how each medium interacts with your preferred acrylic paints and substrates. By combining these options thoughtfully, you can achieve clearer, more vibrant, and durable acrylic artworks.
