How to Use Solid Solutions Gesso Primer (White)

Solid Solutions Gesso Primer is a professional, water-based acrylic primer designed to prepare surfaces for painting. It seals porous materials, improves paint adhesion, and creates a consistent surface with ideal tooth for both acrylic and oil painting.

Step-by-Step Application

  1. Stir Thoroughly
    Mix the gesso well before use to ensure an even consistency and proper dispersion of pigment and binder.
  2. Prepare the Surface
    Ensure the surface is clean, dry, and free from dust, grease, or loose particles. Suitable for canvas, timber panels, MDF, paper, cardboard, plaster, and other porous surfaces.
  3. Adjust Consistency if Required
    If needed, thin slightly with clean water or a flow medium. This is particularly useful for the first coat on very absorbent surfaces. Avoid over-thinning, as this may reduce sealing strength.
  4. Apply the First Coat
    Using a wide flat brush or foam roller, apply a thin, even layer. Work in long, consistent strokes, brushing in one direction to minimise visible marks.
  5. Allow to Dry Completely
    Let the first coat dry fully before applying additional coats. Drying time will vary depending on temperature, humidity, and surface absorbency.
  6. Apply Additional Coats
    For acrylic painting, two coats are generally sufficient. For oil painting, apply three or more coats for improved sealing and durability. Lightly sanding between coats can help achieve a smoother finish if required.
  7. Ready for Painting
    Once fully dry, the surface will provide a stable, lightly textured ground ready for paint application.
  8. Clean Up
    Clean brushes and tools with warm soapy water while the gesso is still wet.

Advanced Techniques and Professional Tips

  • Tinted Gesso Grounds
    Add a small amount of acrylic paint to tint the gesso. This helps reduce glare from bright white surfaces and allows artists to establish a coloured ground before painting.
  • Smooth, Fine-Art Surfaces
    For highly detailed work, lightly sand the final coat using fine sandpaper (400–600 grit). This creates a smoother surface ideal for realism and precision painting.
  • Textured Effects
    Apply gesso more thickly with a palette knife or stiff brush to introduce surface texture. This technique works well for expressive, abstract, or mixed-media applications.
  • Cross-Directional Coating
    Apply each coat in alternating directions (horizontal, then vertical) to improve coverage and reduce brush marks.
  • Sealing Highly Absorbent Supports
    On raw MDF or timber, apply a slightly thinned first coat to seal the surface before applying standard coats at full strength.
  • Custom Absorbency Control
    Light sanding combined with controlled thinning allows you to tailor the absorbency of the surface, making it suitable for glazing, dry brushing, or fluid paint techniques.

Gesso Questions & Answers

Gesso is used to seal and prepare surfaces for painting, improving paint adhesion and preventing uneven absorption.
Pre-primed canvases can be painted on directly, but adding extra coats of gesso allows greater control over surface texture and absorbency.
Two coats are typically sufficient for acrylic painting. Oil painting generally benefits from three or more coats, especially on absorbent supports.
Yes. Small amounts of water or flow medium can be added to improve brush flow, particularly for the first sealing coat on very absorbent surfaces.
Wait until the coat is fully dry before painting. Drying time varies with temperature, humidity, and thickness, but is commonly one to several hours.
Sanding is optional. Sand between coats for a smoother finish, or skip sanding if you prefer more tooth and texture.
Yes. Gesso is well suited to sealing and priming timber, MDF, and hardboard surfaces. A slightly thinned first coat helps seal highly absorbent boards.
Yes. A foam roller can create fast, even coverage and can minimise brush marks on larger surfaces.
No. Gesso is formulated as a ground with binders and fillers to create tooth and controlled absorbency, while white acrylic paint is designed primarily for colour.
Yes. Once fully dry, acrylic gesso provides a stable ground for oil painting. Use additional coats for better sealing and durability.
