Elastomeric means it will stretch and shrink with the seasons. Flash and Patch performs well on chimney seals, asphalt shingles, roof valleys, seams and flashing. This liquid rubber comes in a black gloss and is able to work in cold conditions as low as 40 °F, as well as in wet conditions; this makes it great for temporary emergency repairs. NovaLink FP will not degrade from exposure to sunlight. Videos NOTE: We recommend using this product within 6 months of the date of purchase. NOTE: This caulk will not bond to HDPE plastics. NovaLink FP applies as black and dries to a black gloss. NOTE: ChemLink products do not adhere to polyethylene or polypropylene (recycled plastics) [tabs] Why We Like It NovaLink FP (formerly known as BARR Flash and Patch) will last a very long time without cracking or shrinking and it won't smell like solvent or petroleum-based products.
