Liquitex BASICS Gesso Surface Prep Medium
Product notes: This white gesso provides a reliable base for acrylic and oil painting. The medium is designed for surface preparation and typically requires only one coat for adequate tooth and adhesion. Best for artists who want a versatile white primer on mixed surfaces such as canvas, board, or wood. Limitations: For very absorbent substrates, a light sanding between coats may improve tooth and adhesion.
BLUEBIRD Studio Acrylic Gesso
Product notes: A liquid gesso primer designed to prep canvas, wood, and paper surfaces. The 1-liter bottle supports multiple projects and provides a smooth, matte surface for better paint adhesion. Best for artists who need a dependable, reusable base coat with easy spreading. Caution: Do not apply too thickly, as it can crack when dry on flexible supports.
Apple Barrel White Acrylic Paint
Product notes: A convenient 8-ounce bottle of bright white acrylic paint, suitable as a base coat for stencils and decorative bases. Best for craft projects and base-coating where a solid, matte finish is desired. Limitation: Might require multiple thin coats for fully opaque coverage on very dark underlying colors.
Liquitex BASICS Gloss Varnish
Product notes: A permanent gloss varnish designed to protect finished paintings. It can be mixed with matte varnish to vary sheen and dries to a clear, non-yellowing finish. Best for artists seeking a durable, high-gloss protective layer without altering color. Limitation: Gloss finishes can emphasize brush marks if not applied evenly; consider a test coat on scrap material.
FolkArt Clear Primer
Product notes: A water-based, non-toxic primer with a clear finish that covers about 20 square feet. Best for base-coating surfaces where a transparent primer is preferred before painting. Limitation: Being clear, it may not provide visible tooth for certain paints on very glossy surfaces; test adhesion first.
Buying Guide: How to Choose the Right Base Coat for Acrylic Painting
What surface are you priming? Gesso works across canvas, wood, and paper. For canvas, a traditional white base coat helps true color payoff, while a clear primer can preserve the surface texture. Do you need finish control? Varnishes seal and add sheen; choose gloss for vibrant color depth or matte for a softer look. Is odor or toxicity a concern? Water-based primaries like FolkArt Clear Primer are user-friendly and suitable for indoor spaces. How much coverage do you need? Larger bottles reduce re-priming frequency but require proper storage to prevent drying out.
General tips for base coats
- Always prep a small test area before full application.
- Apply in thin, even coats; allow to dry completely between layers.
- Sand lightly between coats on rough surfaces for better adhesion.
- Store remaining primer upright and capped to prevent skin formation.
