Paint Storage Problems - Sedimentation (Caking)
| 1. |
Sedimentation (Caking) |
|
|
|
Paint pigment is settled in the bottom of the can.
Hard deposit: Hard caking.
Soft deposit: Soft caking.
|
CAUSES:
|
|
|
Excessive storage temperatures. | |
|
|
|
Pigment’s specific gravity too high. | |
|
|
|
Excessive paint pigment in proportion to other components. | |
|
|
PREVENTION:
|
|
|
Store the paint in a dark, cool place, 68 °F (20 °C) or below. If it is stored for a prolonged period, invert the can occasionally. | |
|
|
|
Do not store the reducer/thinner-diluted paint for a prolonged period. Stir it thoroughly to remix before reuse. | |
|
ACTIONS:
Dispose the hard deposit (hard caking). If the deposit is soft (soft caking), stir it up thoroughly to restore a consistent viscosity before reuse.
