T-250

 

This is a 100% solids, two component, equal volume, elastic-type epoxy. It has the proper consistency and working qualities for filling and sealing narrow masonry joints and grooves to prevent their damage as well as to promote a clean sanitary surface. Formula T-250 can also be grouted into cracks, holes and other defects in existing concrete to restore its structural integrity and prevent further deterioration .

Formula T-250 has excellent abrasion and penetration. It bonds tenaciously and permanently to clean dry joints. It reinforces joint and crack edges to prevent deterioration. It seals and protects against fresh and salt water solvents, detergents, waxes, petroleum oil, greases, animal and vegetable fats, mild acids and alkalies, and many other common industrial chemicals. Formula T250 is used wherever saw cut and control joints exist.

Product mixing:

  1. Stir each component separately.
  2. Blend equal volumes of base and reactor.
  3. Mix until color is solidly uniform.

LIMITATIONS:

  1. Grooves and joints must be clean, sound and dry for application.
  2. Should not be applied when concrete is less than 5 to 7 days old.
  3. Do not apply at below 50°F
  4. Due to T-250 being designed as a hard seal, do not use in areas where ultimate movement is more than to%
