Generally, ironing directly over foam can damage both the foam and the iron. Before attempting this, use a protective layer, such as a cloth or parchment paper, to avoid heat-related issues. Additionally, check the iron’s temperature settings and ensure they match the foam’s heat tolerance. Comparatively, low-heat settings work better for delicate materials. Specifically, foam with heat-resistant properties can withstand moderate ironing. Otherwise, it may warp or melt. Whenever you iron over foam, maintain caution and avoid prolonged contact. Eventually, proper technique ensures better results without risks. Altogether, safety and preparation make the process manageable.
