Can You Epoxy Cracked Concrete?

Yes, once the cracks are properly treated. Static cracks are filled; active joints are treated with flexible materials. Coating over untreated cracks lets them telegraph through.

Key points

  • Static cracks — fill with compatible material
  • Active joints — flexible sealant systems
  • Wide or deep cracks may need chase-out and structural repair

Frequently asked

Will the crack come back?

Static repairs stay hidden. Active movement will eventually show through any coating.
