Flexlock Efflorescence Cleaner will remove any efflorescence stains trapped in the concrete pavers and natural stone pores. It will make the pavers look cleaner and more vibrant without discoloring or damaging its surface. This efflorescence cleaning is a necessary step before a sealer is applied. The sealer will be able to get a deeper penetration into the now-clean pores.
Stronger cleaning formula but gentle to the concrete pavers, natural and wet cast stones.
