SpecTilt WB

Application

For New Concrete:

• Mix or agitate SpecTilt WB before each use. Apply undiluted.
• Apply immediately after final steel troweling, once the surface water has evaporated, ensuring full coverage at 250-350 sq ft per gallon on tightly steel troweled concrete.

Bond Breaker Coat:

• Ensure the casting slab is well-cured, smooth, and clean of all contaminants.
• Apply just before adding reinforcing steel, within two weeks of pouring panels, at 400 sq ft per gallon.
• Apply a second coat at right angles after the first coat dries, typically at 500-700 sq ft per gallon, ensuring complete uniform coverage.

For Old or Water-Cured Concrete:

• Ensure the slab is free from any materials that could impair performance.
• Flood the slab with clean water, squeegee off excess, and then apply SpecTilt WB until rejection. A second coat should follow at right angles once dry.

Before Pouring Concrete:

• Ensure the entire treated surface feels dry and soap-like. Test by sprinkling water; it should bead up.
• Mist the slab with water before pouring to prevent surface scouring. Reapplication may be necessary if exposed to rain before the bond breaker coat dries.

Hot Weather Application Tips

• Apply cure coat immediately after finishing to ensure a uniform surface film accumulation, especially on porous or roughly finished slabs.
• Cool the slab and fill any remaining porosity with water before applying bond breaker coats.
• Ensure uniform application to avoid the “osmotic effect” where water migration from fresh concrete into the dry slab can affect panel surface hydration.

Additional Considerations:

• Use caution with stack panels and waste slabs to prevent sticking; a double coat may reduce this risk.
• If applied correctly, panels can be painted once the moisture content reaches an acceptable level for paint application, adhering to the paint manufacturer’s instructions.
