Flexible Concrete Floor Control Joint filler

  • For cracks and control joints
  • UV resistant polyurea-resists fading
  • Cures to a clean finished look
  • Packaged in  dual 300ml, 1:1 Ratio Dual Tube Sets ( 3/8 x 24 )mixer and Nut Included)
  • Ready for regular traffic in about an hour
  • The Concrete temperature must be 50 degrees F-10 Deg C or higher at the time of application


Common Applications:


  • Basements: Use this product to fill expansion joints in basement floors.  An expansion joint is a common source of moisture and dangerous soil gases like radon, 85-90 seals the joint while still allowing slab movement.
  • Warehouse floors: Expansion and control joints in warehouse floors often catch the small wheels of carts.  Emecole 85-90 self-levels in the joint and it can be shaved smooth for a seamless transition from one slab to the next.
  • The Joint Between a Patio and a Foundation:  There are typically gaps between a patio and the foundation of a home.  Rainwater collects on the patio and it can run down into that gap.  That water then runs down the depth of the foundation and increases the likely hood of water in a basement.  85-90 can waterproof that gap so the water does not run down the foundation wall.


Flexible control joint filler for cut and formed expansion joints for weather seal and profile. Warehouse floors-sidewalks- transitions.
