Painting your home is a big project, but with paints, primers and supplies from Walmart, you can get the job done — even on a budget.
For indoor painting, start by moving furniture out of the room or covering it with a drop cloth. Remove wall hangings, switch plates, etc., and use masking tape and plastic sheets to cover objects and surfaces that won't be painted and can't be moved. Cover the floor with drop cloths. Wash the walls and use a drywall compound to fill holes and smooth out rough areas. Once the compound is dry, lightly sand it with fine-grit sandpaper and vacuum up the dust.
Paint from top to bottom, starting with the ceiling and then doing the walls and woodwork. Paint the ceiling edges with a paint brush, creating a 2-3 inch wide border, and use a paint roller and extension handle to paint the ceiling itself. Use a brush to paint corners, ceiling edges and areas adjacent to woodwork, then use a roller to paint the walls. Paint molding and woodwork with a brush.
For exterior painting, first remove flaking, chalky or blistered paint with a paint scraper, putty knife and wire brush or a power washer. Fill holes in wood siding with an exterior-grade patching compound and seal cracks with exterior caulk. Clean the area and mask off areas that won't be painted. Paint gables first, then main siding, windows, siding trim and doors.
