HIAC should be applied every 2 years and not every year.
PREVENTION
Be sure the surface is thoroughly clean and dry prior to resealing to ensure moisture is not trapped between layers causing adhesion failures.
SOLUTION
After years of resealing and building up layers of sealer, sometimes just a good solvent wash will provide the same look of a new coat of sealer. Wet the surface with the solvent and move it around with a roller to allow for even coverage.

What does higher solids mean?
Products with a higher solids content provide a higher shine or sheen. As far as performance, higher solids will provide longer protection. However, these products could be more difficult to apply. As always, a licensed, professional contractor is recommended.
