The Step-by-Step FlexKRETE Repair Method.
CASE STUDY: Repairing Spalls Permanently
Customer: Lowes Home Improvement
Problem: Concrete spalls and damage from forklifts
Solution: Longterm repair using FlexKRETE Superior Concrete Material
1. Remove loose and hollow sounding concrete with concrete scarifier, milling machine, grinder or by blasting. Void-test by dragging chain or "pinging" with hammer. A clean, white, rough and solid substrate is desired
2. Use a diamond blade saw to establish perimeter by cutting 1/2" vertical 'key' with 45º slope from inside.
3. Route cracks with crack chaser, a minimum 1/2" deep to prepare for filling.
4. Blow or vacuum all dust and debris from cracks and prepped areas.
5. Using pressurized spary-gun, apply thin coat of FlexPrime, leaving no puddles or ridges. Apply just enough FlexPrime to darken concrete, then allow to tack.
6. Mix 2 parts sand with 1 part catalyzed FlexKrete and force flush into cracks with a trowel.
7. Mix 3 parts sand with 1 part catalyzed FlexKrete, fill spall areas and smooth with trowel, fresno or screed, extending to, and forcing material into perimeter 'key'.
