FAQs
Q: Are silicone-based sealants compatible with RoofSeal?
A: No. Silicone sealants or lubricants should not be used near RoofSeal, as they interfere with adhesion.
Q: What should be used to clean the surface before applying RoofSeal?
A: Use EternaClean or a residue-free solvent such as acetone or lacquer thinner for best surface preparation.
Q: When is RoofSeal Plus recommended over RoofSeal?
A: RoofSeal Plus should be used for rough, porous, or uneven surfaces that need extra sealing thickness.
