Surface
Preparation
|
|
All
receiving surfaces must be structurally sound, clean, free of dust,
dirt, silicones, paint products, efflorescence or any other contaminant
which could prevent proper penetration. Allow new cement and masonry
surfaces to fully cure (approximately 28 days) prior to application.
A sample area should be tested to be sure no color variation will
occur. |
|
|
|
|
|
Application
|
|
For best results,
use suitable spray equipment, maintaining consistent spray pressure.
Starting at the bottom, apply a fog coat followed immediately by
a saturation coat. Do not over apply to the point where material runs or drips.
Protect all glass and metal surfaces from direct contact
or overspray. For smaller areas, a brush or roller may be used.
|
| |
|
|
|
Clean
Up
|
|
Clean
all tools and equipment with detergent and water immediately after
use. Clean up drips, runs, and overspray on non-treated surfaces while
MicroSeal II is still wet, using detergent and water if necessary. |
| |
|
|
|
Storage
|
|
Do
not store in direct sunlight. Storage temperature should be 50°
- 90° F (10° - 32° F). Protect from freezing. Shelf
life is one year with proper storage. Keep container
tightly sealed when not in use. |
| |
|
