Mont Marte Professional Stretched Canvases feature an 18mm deep frame and provide a professional and polished look. Triple coated with a universal primer, these canvases are ready for immediate painting. Made from acid-free 380gsm canvas, and constructed from 100% cotton duck fabric with a high-density weave, they provide a robust and durable surface. Mitered corners and double-row back stapling add to the canvas’s clean and professional appearance. For larger sizes over 60cm, the canvases include bracing and wooden stretcher keys / wedges for added stability and support. The 18 x 38mm pine wood frame, combined with kiln-dried stretcher bars, ensures the canvas’s structural integrity and resistance to warping. Suitable for use with both Oils and Acrylics.
