Brick has been painted in white semi gloss. I want the flat white to be thicker to soften brick and mortar. I have 5 gallons of white interior paint on hand. Thanks!!! Kathyb

    Experiment by just putting it on with a long-hair roller.

    Messing with the paint itself, especially 5 gallons, probably should only be done by a pro who has the equipment to make it blend completely. You know how long it takes on their machine just to mix colors.

    You can thicken it by adding joint compound to it. You will have to find the dry stuff. You will also need a very powerful drill so you can use a special stirring rod to blend your paint and compound mixture.
