I wanted to put a neutral colour on the part of the wall that is darkly coloured, so that when I come to paint all the walls red, it will come out the same shade on all walls. I picked up the cheapest neutral colour paint I could find and paint an entire wall (although it is a small wall) with it. Stupid me bought paint for wood and metal. It came out very glossy and was wondering if I am okay to paint over this with the red. Will it stick okay? Will the red come out glossy too despite it being matte?
