Prestretched canvas Biotherm 64040, white, 400×400 mm, pack of 3

Prestretched canvas Biotherm 64040 is a ready-to-use white cotton/poly canvas stretched on wooden stretcher bars, size 400 × 400 mm, sold as a pack of three. The primed surface suits sketching, layering and finishing with acrylics, oils and mixed media, making these small canvases convenient for studies, practice pieces and craft projects.

Advantages

The canvases come pre-stretched on solid wooden stretcher bars and have a white, primed surface suitable for acrylic, oil and mixed-media techniques. Their compact 400 × 400 mm format and pack of three offer convenience for repeated practice, small original works or series studies. The combination of cotton/poly fabric and multiple priming layers creates a surface with good adhesion and balanced absorbency for common painting media.

Suitable for

• Acrylic painting
• Oil painting
• Gouache and mixed media studies
• Sketches, small finished artworks and craft projects

When it may not be suitable

These 400 × 400 mm prestretched canvases are intended for small-format works and practice; they may be too small for large-scale compositions or mural-size pieces. Artists requiring a very coarse or very fine tooth, archival cotton-linen grounds, or specific museum-grade priming may prefer alternative museum or custom-stretched supports.

Key specifications

• Format: 400 × 400 mm
• Pack quantity: 3 canvases
• Fabric: cotton/poly blend
• Surface: white, factory-primed (multiple coats)
• Suitable media: acrylics, oils, gouache, mixed media
• Stretcher bars: wooden construction with fitted corners

How to use

Start by checking the surface for dust and handle the canvas by the stretcher bars to avoid marking the primed area. Secure the canvas on an easel or flat table, sketch your composition on the primed white ground, and apply paints as required. For oil painting, allow sufficient drying time between layers and follow standard paint thinning and varnishing practices. Store unused canvases flat or upright in a dry environment to prevent warping.

What to consider before purchase

• Intended painting size and whether 400 × 400 mm fits your project
• Compatibility of cotton/poly primed surface with your chosen media (acrylic, oil, mixed media)
• Pack of three quantity versus the number of works or practice pieces needed
• Preference for tooth and fabric type (cotton/poly blend versus pure cotton or linen)

Usage recommendations

For best results with acrylics and mixed media, prime edges and allow the ground to acclimatise to room temperature before painting. When using oils, work in thin layers and allow thorough drying between coats; consider an isolation layer or final varnish for protection of finished small-format works.
