I have been painting the exterior of my mother-in-laws house with oil based primer and then an oil based “gloss” top coat. She says it has too much shine to it. It needs a second coat and I was wondering if there is a way to add something to the rest of the paint I have to make it a semi-gloss or flatter? The paint is from Sherwin Williams and I have about 10 one gallon cans left.
Exterior oil based gloss to a semi-gloss?
