Clean Lift 20/20

Application

For New Concrete:

• Mix well before use. Apply undiluted.
• Apply after final troweling and when surface water has evaporated.
• Ensure full coverage on steel-troweled concrete at 250-350 sq ft per gallon.

As a Bond Breaker:

• Apply on a well-cured, smooth, and clean slab.
• Remove all contaminants before application.
• Spray apply the first coat at 400 sq ft per gallon. After drying, apply a second coat at 500-700 sq ft per gallon at right angles to the first.
• Ensure complete and uniform coverage. Reapply if necessary for even coverage.

For Old or Water-Cured Concrete:

• Ensure slab is clean and free of curing compounds.
• Saturate with clean water, remove excess, then apply Clean Lift 20/20 to rejection. Apply a second coat as above.
• Ensure the treated surface feels dry and soap-like before pouring concrete.

Before Pouring Concrete:

• The treated surface should have a dry, soap-like feel.
• Test with water droplets; they should bead up.
• Flood the slab with water prior to concrete pouring to avoid surface scouring.

Special Considerations

• Reapply if exposed to rain before drying.
• Use a low-pressure sprayer for application.
• Contact SpecChem for advice on concrete mixes containing pozzolans or for special situations.

Hot Weather Tips

• Apply cure coat immediately after finishing, before joint cutting.
• Saturate the casting slab before bond breaker application to fill porosity.
• Ensure uniform, adequate coverage to prevent water migration and surface defects.
