LR-321 Formulas Offer Versatility for Various Crack Injection Applications

LR-321 crack injection epoxies offer versatility for various high performance structural applications. LR-321 LV (formerly known as LR-321) is a low viscosity epoxy for cracks that range from 1/8 in. to < 1/4 in. LR-321 SLV is a super low viscosity epoxy for fine cracks up to 1/8 in. LR-321 TXO (formerly known as LR-321G) is a medium viscosity epoxy with unique thixotropic properties making it ideal for injection of blind-sided cracks ≥ 1/4 in.

Great product! Miracle Bond can pretty much fix anything around the house, from a small concrete crack on my wall to repairing the rotten wood panels around my door with a coat a paint everything looked brand new!
