penetrating sealer not only densifies and hardens concrete making it up to 50% stronger, but it is the go to
choice to harden and prime basements and driveways. It is also an excellent choice for polishing concrete.

• Polished concrete/extremely smooth concrete surfaces
BENEFITS
• Increases abrasion resistance
• Strengthens concrete up to 50%
• Excellent penetration
• No change in appearance
• Low VOCs
• Resists UV degradation
PREPARATION
Avoid contact with skin, eyes and clothing. Wash hands after use and do not take internally. Please refer to
the product Safety Data Sheet (SDS) before using. The preparation process should be followed to ensure
adequate penetration and optimum performance:
Step 1:
The concrete substrate must be structurally sound, thoroughly dry and clean. Wait at least 24-48
hours after rain and/or pressure washing before sealing; concrete should be visibly dry.
Step 2:
Remove all paints, previous sealers and/or adhesives before application.
Step 3:
The substrate must be clean of oil, grease, dirt, wax, curing compounds, efflorescence and other
contaminants that might interfere with the penetration of the sealer.
Step 4:
If acid is used to clean the concrete, neutralize the surface completely and rinse it with water prior to
application. Then wait for the concrete to dry out for at least 24-48 hours.
Step 5:
The surface-zone moisture content of the concrete should not exceed 4%wt.
