BARR Flash and Patch is a non-toxic, moisture-cured, elastomeric caulk/sealant designed specifically to waterproof and repair all types of residential and commercial roofing. 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 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. BARR Flash and Patch will not degrade from exposure to sunlight.
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. When you have serious roofing problems, being able to apply this type of material in cold wet conditions is a big plus.

Surface or Product Preperation
Surface should be clean, dry and free from all contamination including: dirt, oils, grease, tar, wax, rust and any other substance that may
inhibit the sealants performance. DO NOT use petroleum solvents such as mineral spirits or xylene to clean your surface before using this product. Instead, remove all dirt, oil, loose paint, frost and other contaminates with alcohol. Horizontal applications will require tooling. Allow treated wood to cure for six months prior to application. Do not use in areas subject to continuous immersion of water or chemicals. Do not use on TPO without Chemlink TPO Primer. In most instances BARR will not require a primer
However, certain applications or substrates may
require a primer to ensure a long lasting bond and
weatherproof seal. It is the applicators responsibility
to determine the need for a primer. Chem Link
recommends a primer be used for any application
where prolonged immersion is anticipated.
