"Prior to sealing, cracks should be cleaned and any peeling caulk removed to aid adhesion."
"Latex- type caulks clean up easily with water and are paintable. Caulks that dry clear are often easier to use than pigmented caulks since they don't show mistakes. "
"Fill in small cracks inside and around cabinets, where the wall and floor connects, around baseboards and where fixtures meet the walls with silicone or acrylic latex caulk. Use enough caulk to completely cover the crack. For a neater appearance, smooth over the wet caulk with a gloved finger moistened with water."
"Seal small cracks on the walls, on wood surfaces and on flooring with a coat of water-based latex paint."
"Stuff steel wool or copper mesh in large cracks that are 1/2-inch wide or larger, followed by an application of caulk or a coat of spackle."
