We had our mantle painted white but feel like the grain showing doesn’t look right. Our painter said he can’t make it smooth but suggested repainting it grey (like kitchen island) or using gel stain. I feel like if we can’t hide the grain we’ll need to do stain but not sure about how gel stain looks or what color. Any suggestions would be much appreciated on what to do with mantle/fireplace. This is a focal point in our home and the kitchen cabinets are painted white with matte black handles across from this and floor Is special walnut stain.
