Application Instructions

Crack Repair (Negative Side)

Application Instructions:

1. Prepare the crack using a 1" (25mm) wide chisel, chip a 1" wide chase along the entire length of all cracks to a depth of 1.5" (38 mm).
2. Fill one-third of the depth of the chase with Krystol Plug™ and hold until water stop flowing or seeping.  Mix only enough material as can be placed in 1 minute.  Repeat the procedure from one end to another.
3. Pack the Krystol T1® into the chase to a thickness of 1/2" (13 mm) over the Krystol Plug. The chase should now be two-thirds full.
4. Fill the rest (outer third) of the chase flush to the surface with Krystol Bari-cote™. Mix only as much as can be placed in 15 minutes.
5. Coat the repair area, extending at least 8 inches to either side of the repair, with Krystol T1® and then apply a second slurry coat of Krystol T2® after the Krystol T1 application has set hard. Mix in the same proportion and apply at the same rate of coverage.

Note: The chase must be square shaped. Do not form a V shaped chase. Surfaces to be treated must be pre-wet to a saturated-surface-dry (SSD) condition. Do not leave any standing water.

For more detailed application instructions, please read Technical Bulletin 101.
