Preparing to Paint a Fireplace Preparing to Paint a Fireplace
When preparing to paint your fireplace remember to use high-temperature paint. Be sure to clean your surface before working with it because the cleaner your surface is before painting, the better the paint or stain will adhere.
Preparing Your Fireplace for Painting
Use a stiff bristle brush to remove crumbling or loose mortar, loose paint from the brick to prepare to paint. Vacuum up the dirt, dust and debris as you brush so that it does not remain on the surface. Follow the dry brushing with a brushing with hot, soapy water to clean the surface thoroughly. Allow to dry. Patch any holes, missing mortar or bricks. Paint the bricks with two coats of an oil-based primer and allow to dry.
The best paint to use to paint bricks is an oil-based paint. Also, be sure to use a high temperature enamel paint for the inside of a fireplace because it will withstand the heat, flames and high temperatures of a fire better. If you're painting the inside of a fireplace that is no longer used for fires, then any kind of paint will do.
