Choose an appropriately colored latex paint for your base coat. Black or white base coats will leave you with undesirable results after you lay the glaze. Ideal base coats for using metallic gold glaze will come from yellow or tan color ranges. Pick a color based on how bright or dark you want your walls to be. For example, a mustard yellow or golden tan will result in a very realistic gold color, while a lighter yellow will be brighter and have a more polished look.
Prepare your walls. Use paint tape to protect any surfaces you don't want to paint, like borders or window frames. Lay down plastic sheeting to protect your floors. Use brushes to paint smaller areas and to get into corners and edges. Pour some paint in the paint tray and use the rollers to lay your base coat. Allow the base coat to dry completely.
Use a foam roller to paint on the glaze. If you're working with a particularly small area, you can use a soft bristled brush; paint using a crisscross pattern until the entire surface is evenly coated. Glaze typically takes longer to dry than paint, so to avoid streaking, you should take your time to make sure the coat is even and smooth. If your walls are particularly expansive, streaking is unavoidable if you're using a roller to paint; rent a paint sprayer to lay your glaze.
