Painting Stretcher Frame Astra 50×60 cm, Astra model FC04AST

Astra painting stretcher frame 50×60 cm (Astra model FC04AST) is a wooden support frame designed for stretching canvas to produce a flat, stable painting surface. The 50×60 cm format provides a medium-sized rectangular support suitable for studio work, finished artworks and practice canvases. Constructed from kiln-dried timber with mitred corners, this stretcher frame is compatible with primed or raw canvas and can be used for oil, acrylic and mixed-media applications.

Advantages

The stretcher frame offers dimensional stability and a uniform flat surface that helps prevent canvas sagging and warping. Its lightweight wooden construction makes it easy to handle and mount, while mitred corner joints allow for even tension across the canvas. The frame’s standard depth supports typical gallery framing and hanging systems, and its plain profile is suitable for priming or finishing edges as required by the artist.

Suitable for

• Stretching primed or raw canvas for oil painting
• Acrylic painting and mixed-media works
• Studio practice pieces and studies
• Mounting prints or photographs for display
• Preparing canvases for framing or gallery presentation

Key specifications

• External dimensions: 50 × 60 cm
• Material: wooden stretcher bars (kiln-dried timber)
• Corner type: mitred corners designed for even tension
• Suitable surface: raw or primed canvas (oil, acrylic, mixed media)
• Profile: standard depth suitable for framing and hanging

How to use

Place the stretcher frame on a clean, flat surface and align the canvas over the frame so there is sufficient overlap on all sides. Starting from the middle of one side, staple or tack the canvas to the rear of the stretcher bar, then move to the opposite side and pull the canvas taut before fastening. Continue working from the centre toward the corners, alternating sides to maintain even tension. Trim excess canvas after securing and finish the corners neatly. If using raw canvas, apply a suitable primer before painting according to the primer manufacturer’s instructions.

Usage recommendations

For best results, tension the canvas evenly and avoid over-stretching. Store stretched canvases flat or hung vertically in a stable, dry environment to prevent warping. Use appropriate primers and allow full drying time before varnishing or framing.
