Application

Preparation

• Follow all ACI recommendations.
• Remove all contaminants such as dirt, grease, and loose materials.
• Profile concrete substrates to a minimum CSP #4; shot blasting is preferred.

Priming

• Prime withSpecPoxy 1000at approximately 100 sq. ft. per gallon.
• Apply using a notched squeegee, broom, or roller.
• While epoxy is still wet, broadcast coarse dry sand to refusal.
• Allow to dry for a minimum of 12 hours, then remove loose sand before applyingSpecLevel PCT-Gray.

Mixing Instructions

• Small Batches:Mix 7 pints of water per 50 lb. bag for 3 minutes.
• Large Batches:For 34 bags, mix for 45 minutes.
• Pumping:Mix for 3 minutes in the pump’s mixing tank.
• Extended Mix:Add 15 lbs. of 3/8” pea gravel per 50 lb. bag during the last minute of mixing.

Installation

• PourSpecLevel PCT-Grayover the substrate and spread with a long-handled spreader or gauge rake.
• Self-levels in the first 20 minutes at 70°F.
• Accepts foot traffic in 24 hours.
• Use cleated shoes during installation for best results.
