1. |
Clean surface along the crack. Blow out crack with dry and oil-free compressed air. |
| 2. |
Bond injection ports with CI 070 Crack Sealing Compound. Port spacing approximately 6-12" with wider spacing for thinner slabs. |
| 3. |
Seal the crack with CI 070 EP in strips of minimum 2" wide, 1/8" deep. |
 |
4. |
A light tap with a hammer to the rear end of the cartridge breaks the glass cylinder releasing the hardener. Mix by see-saw motion for approx. 30 motions--do not shake. |
 |
5. |
Puncture the seal of the cartridge tip. Then screw on connection hose. Remove foil from rear of cartridge. |
| 6. |
Plug connection hose to bottom port. Tighten union nut, insert air relief stopper at next port above (non-return valve is opened--entrapped air can escape). Use only cap nut type dispensers |
 |
7. |
Inject CI 060 EP resin until it appears visibly in the next port above. Remove air relief stopper (non-return valve is now closed) and insert into next port. Continue injecting into original port until the port will accept no more resin when normal hand pressure is used on the dispenser. |
| 8. |
Detach connection hose from port and plug to the next higher port. Repeat operating steps 6 and 7 up to the end of the crack. |
 |
9. |
After the injection resin has set--generally overnight--the ports and the sealing compound can be removed with a flat chisel. If required, the surface can be ground even. |
