U.S. Art Supply Clear Gesso Primer

It dries transparent, allowing the base surface to show through while providing the necessary tooth for paint. This primer is a versatile alternative to traditional white gesso and can improve blending and color vibrancy. It enhances surface grip without altering paint consistency, making it suitable for mixed-media projects that combine oil and acrylic media.
Flood Penetrol 1-Qt. Clear Paint Additive
Penetrol is a clear additive that improves adhesion, penetration, and flow of oil-based paints, varnishes, and primers. It fortifies exterior oil-based and alkyd paints, and helps the paint perform under varying weather conditions. This product is particularly useful for improving spray and brush application, reducing brush marks, and delivering a smoother, more even coat on wood, metal, and masonry surfaces.
Minwax 1/2 pt Clear Fast-Drying Oil-Based Polyurethane
Minwax Clear Fast-Drying Oil-Based Polyurethane provides durable interior protection for wood surfaces such as furniture, floors, and cabinets. This oil-based top coat dries to a warm satin finish, enhances the natural beauty of the wood, and offers excellent resistance to scratches and spills. It’s ideal when a traditional, durable oil-based finish is desired for wood projects that require a long-lasting, clear protective layer.
Nicpro Clear Gesso Primer for Acrylic Painting
Nicpro Clear Gesso Primer offers a premium, non-toxic formula in a large 21.2-ounce tub. It dries to a transparent finish, maintaining visibility of underlying sketches while adding tooth for subsequent acrylic or oil paints. The primer improves surface adhesion and color saturation without altering the paint’s consistency, helping to keep artwork bright and true to tone.

This product is suitable for sealing and preserving painted surfaces with a clear, hard finish.
Rust-Oleum Varathane Clear Interior Polyurethane
1/2 pint of Rust-Oleum 9061H Varathane Clear Interior Ultimate Polyurethane provides a fast-drying, glossy finish that highlights wood grain. It is self-leveling and minimizes brush strokes, delivering a uniform, clear protective layer for interior wood projects. This oil-based option is preferred for a high-gloss or clear satin-like look, depending on the sheen chosen.
FolkArt Enamel Paint
FolkArt Enamel Paint is a one-step, self-sealing acrylic enamel that dries to a durable finish. It is highly pigmented and offers quick-drying properties with scratch resistance. While not a dedicated topcoat, it provides a clear protective layer when used as a finish for small projects, and can be baked for added durability if needed.
Minwax Water Based Oil-Modified Polyurethane
Minwax Oil-Modified Polyurethane combines water-based convenience with the warmth of traditional polyurethane. It protects interior wood surfaces, including furniture and floors, and offers a satin clear varnish with elegant depth. The product is suitable for projects seeking a durable, low-odor finish that still preserves natural wood beauty.
Buying Guide: Key Purchase Considerations
- Material compatibility: Choose products compatible with your base—oil-based paints require sealants and primers that bond well with oil and enamel finishes.
- Finish and sheen: Determine whether you want a gloss, satin, or matte look, as this affects color depth and the visibility of the underlying surface.
- Drying time and handling: Consider cure time and recoat windows to avoid dust, brush marks, or tackiness.
- Surface type: Wood, canvas, metal, or plaster surfaces may require different primers or topcoats for optimal adhesion.
- Non-toxic and safety considerations: If using indoors or with children, prioritize low-VOC and non-toxic formulations when possible.
- Application method: Some products are spray-based while others are brush-on or wipe-on; select based on project size and precision needs.
- Durability and protection: For high-traffic surfaces, prioritize durable polyurethanes and protective clears to resist scratches and moisture.
- Transparency and base color: Clear primers and gesso may preserve underlying tones; for fully opaque finishes, white or tinted primers may be preferred.
- Maintenance: Some finishes are easier to touch up than others; consider how you’ll repair or refresh the coating over time.
