Canvas Board. 8×8.

Description

An 8×8-inch (approx. 20.3 × 20.3 cm) canvas board is a square, rigid art surface featuring a cotton fabric stretched over and glued to a hardboard or MDF backing. These boards are preferred for their portability and stability compared to traditional stretched canvases, as they do not warp or sag during the painting process.

Common Technical Specifications
Most standard 8×8 canvas boards share several professional-grade features:
Fabric Material: Typically made from 100% cotton duck or cotton cloth, often featuring a medium or fine grain texture that helps paint adhere.
Priming: Most are pre-primed with 2 to 3 layers of acid-free acrylic gesso, making them ready to use immediately for oil and acrylic paints.
Core Board: The inner support is usually a 2mm to 4mm thick MDF (Medium Density Fibreboard) or high-quality paper board designed to be lightweight and non-bending.
Archival Features: Quality boards are acid-free to prevent the yellowing or deterioration of artwork over time. Some also include anti-fungal treatments to protect against decay in humid environments.
