Dā-mite® generates heat after it is mixed with water
Unexpected overheating can cause the product to blow out of holes when hot steam escapes after filling drilled holes. Dā-mite® can overheat if:
- Wrong type is used at wrong temperature
- Hole size is beyond diameter shown in literature or
- Mixing water is too warm.
Once blowout shot occurs, it will occur 3 - 4 times out of the same hole and it may occur in other holes. Stay away from the filled holes area when blowout shots happen.
To avoid blow-outs
a.Use the right color grade of Dā-mite® for the temperature range and hole diameter (refer to the temperature chart on sales literature)
