Question: Does Alphabond require a primer?

Answer: Alphabond, our specially formulated roofing repair tape, does not require a primer. However, surfaces should be clean, dry and free of greases and oils in order to ensure optimum performance.

Question: Why purchase butyl tape?

Answer: Compared to other gasketing materials, butyl tape holds several critical advantages. Most notably, it is cleaner, safer and easier to work with than solvated products. Compared to open and closed cell foam tapes, butyls have a long track record of superior durability and typically at a lower price. In both field and laboratory settings butyl tapes have proven to withstand the elements longer and more effectively than their foam and solvated counterparts.
