About FlashSeal Elastomeric Flashing Sealant, 1 Gallon (Black)
Overall Feedback:
89% positive
93% appreciated the waterproofing feature
After the first rain, there was no leak, indicating that the deck-sealer is effective in waterproofing.
I tried the deck-sealer on leaky air vents that left a gap between the brick and wood. After using it, there were no more water leaks.
I tested the deck-sealer by drilling holes in a small metal bucket, sealing the bottom, and filling it with water. After several weeks of being submerged, the sealant was still effective.
92% were satisfied with the drying time
I found that the product dries so fast that by the time I finished applying the base coat on the bottom section of the chimney and the two sides, the bottom was essentially mostly dry.
