The substrate should be free of dust, grease, wax, oil, dirt, loose plaster, laitance, curing compounds, paint and all other friable materials and contaminants likely to prevent the adhesive bonding.
All substrates should be structurally sound, securely fastened and properly supported to eliminate any movement that may cause cracking.
Smooth surfaces on new and old concrete should be scabbled.
Prefill any dormant cracks with CEMIX CEMGROUT GP or CEMIX REPAIR & GROUT.
It is recommended to prime the surface with a CEMIX bonding agent before the applicaton of CEMIX RAPID REPAIR H.
