Prime Plug-It is fast-setting, requiring only 5 to 10 minutes initial set time and only 15 to 20 minutes final set time in accordance with ASTM C-191. Prime Plug-It is also easy to apply, and delivers 6,000+ psi of compressive strength after 28 days according to ASTM C109.

You can use Prime Plug-It with new and old concrete, with architectural concrete, on vertical concrete surfaces and concrete columns, inside tunnels and parking garages, and on below-grade concrete structures.
