I got the same color of existing wall color. But the problem is that even though the existing paint is at the least glossiness, it is still a lot more glossy than the old walls. Is there any paint or method I can use to reduce the glossiness of wall paint so I can match the old walls with the paint I got?
Edit: To further the conversation. Is there any coating paint that will reduce the sheen gradually by the number of layers being applied. For example, when I apply first layer, it will dull the sheen for certain percentages, and then the second layer will dull the sheen for certain amount, until I can very closely match the surrounding color and sheen?
