How to use injection capsule for crack reparing

1. Preparation of the surface for basic work.

injection capsuleCheck the state, width and depth of crack before working and decide work process.

First of all, remove the dust and foreign substances around the region of sealing by using spatular or wire brush and if there are oily substance including oil attached on the surface, remove the dirt on the surface completely using detergent like thinner.

2. Deciding the location for installing rack

Decide the suitable interval for installation of plate for fixing rack
depending on the state and depth of cracks. Generally, it is attached at about 20cm’s interval and interval may be enlarged according to the state of crack.

3. Combination of epoxy sealant

Mixing sealant and hardener 1 : 1 in the combination plate by using broad spatula.

*Taking out sealant and hardener separately and check the quantity and mix them.
*Check sealant attached in the middle of bottom and to spatula and then mix them.
*If they are a little solid, mix them with epoxy thinner

4. Seal the region around the crack

In order for epoxy injection material not to be leaked, seal the region around crack by 1mm of thickness and 30mm of breadth evenly with epoxy sealant by using of plastic spatular.

* even small crack causes leaking

5. Attaching the plate for fixing rack

Apply epoxy sealant to the below side of  edge evenly rolling sealant and attach  on the installation location as twisting a little.
(hardening takes about 24 hours at 25 degree Celsius)

6. Injection of epoxy

After mixing epoxy injection material 2 to 1 in stirring container(small basin) completely and put about 30cc of epoxy injection material into injection capsule and then hang rubber band on the rack. When you hang injection capsule with rubber band, support the other side to prevent leaking due to raising of other side.

When injection material is consumed, refill quickly with other one.
If there is air in injection capsule, expel the air.
Hardening of epoxy injection material takes about one day in summer and about 2 days in winter.
Complete hardening of it takes about 7 days)

7. Finishing work

Remove injection capsule and after confirming hardening of injection material. Clean the surface by hammer, spatula and grinder and finish it as almost original state by using of one coat crack covering material, or paint(after applying) and other material.

* If you use torch to remove injection capsule, epoxy sealant and , it may cause the risk of fire and burning epoxy. Be careful.

Notice: When you work at below 5 degree Celsius, viscosity rises, so injection may not be smooth and hardening time may be lengthened causing the risk of defects.
