The Benefits of TK Product’s Concrete Finishing Aid

  • Increases “cream” and workability of the concrete without impacting the water/cement ratio
  • Lubricates concrete surfaces and reduces trowel and equipment wear
  • Prolongs workability in hot, humid, dry, and windy conditions.
  • Improved impact and abrasion resistance
  • Retains moisture in the slab for optimal curing and reduces curling and shrinkage
  • Minimizes checking, crazing, and scaling
  • Facilitates easier finishing with silica fume and air-entrained concrete
  • Reduces efflorescence and dusting for lower maintenance requirements over the life of the slab
  • Extremely low VOC content (<5 g/L)
  • Reduced potential for alkali-silica reaction (ASR)

TK-SLAB ASSIST is designed for use during final concrete finishing and should be applied to fresh concrete before screeding, floating, or troweling have begun.

Use a clean, hand-pump tank-type sprayer with a low-pressure tip to distribute the product evenly. Lightly mist TK-SLAB ASSIST over the entire surface to be treated and immediately follow with screeding, floating, troweling, or other finishing procedures.

Re-apply TK-SLAB ASSIST to any localized areas where the concrete has begun to prematurely dry.

Clean tools and spills with soap and warm water before the material dries.
