Painting thermofoil kitchen cabinets is risky because the vinyl wrap on MDF tends to peel and reveal texture unless you fully strip and refinish them. This makes paint jobs on thermofoil cabinets less durable and prone to failure, especially when paired with brown tile floors and green countertops. If your cabinets are thermofoil, consider keeping their finish and focusing on updating floors, hardware, or backsplash instead for a better upgrade.
