    摘要: Sealants and caulks (i.e., polymeric fillers) disclosed herein are polymeric fillers that comprises a polymeric material composition and one or more lipolytic enzymes dispersed within the polymeric material composition. In preferred embodiments, the polymeric material composition is an acrylic latex sealant such as that in the form of a caulk and the one or more lipolytic enzymes comprises a lipase such as, preferably, a triacylglycerol lipase. Advantageously, the one or more lipolytic enzymes of such sealants and caulks degrades lipid-containing contaminants and resulting lipid-containing stains that contain lipids. The degradation is a result of the ability of a lipolytic enzyme to catalyze a reaction on a lipid-containing substance (i.e., a substrate) to hydrolyze or move (e.g., intra-esterification) ester bonds of such lipid-containing substance. This lipid-degradation functionality at least partially inhibits the growth of such mold and mildew resulting from exposure to lipid-containing contaminants.

    摘要: A system for installing pre-painted moldings. The system includes pre-painted moldings each configured to be fastened to a wall by fasteners. The system also includes a caulk material, filler material, concealer material, and touchup paint each color matched to the paint color applied to the moldings. The caulk material is configured to fill a gap defined between each of the moldings and the wall to which the molding is fastened. The filler material is configured to fill a gap defined between any abutting portions of the moldings. The concealer material is configured to conceal any surface disturbances caused by the installation of the fasteners. The touchup paint is configured to adhere to the paint pre-painted on the moldings. The system may also include a marker configured to apply a coating color matched to the paint applied to the moldings, a scraping tool, and/or a buffing tool.
