Since resin is pretty heavy, canvases are not recommended as a painting surface. If you use them, the weight will press too much in the middle of the canvas, which will bend through - causing the resin to flow into the middle. This will cause a pool of all the resin in the center of the canvas. Therefore, we recommend wooden painting boards. Remember to always use non-absorbent surfaces, otherwise, the resin will be absorbed into the painting ground and disappear.
