Recoating can be an excellent way to restore appearance and performance when the existing epoxy floor is properly prepared and is still firmly bonded to the substrate. Many existing resin floors remain structurally sound even after years of service but may show wear, dullness, or abrasion in high-traffic areas. With correct preparation, these floors can be renewed by applying a compatible Epoxy.com coating system.
This bulletin outlines the correct procedure for cleaning, testing, repairing, and mechanically profiling a properly prepared existing epoxy floor prior to installing a new Epoxy.com system.
A clean surface is essential before any further evaluation or preparation can occur. Remove loose dirt and debris, then scrub with a suitable detergent or degreaser. For oily or unknown contamination, we recommend contacting your trusted local janitorial supply house for the correct cleaner for your specific contaminants.
Rinse thoroughly and allow the floor to dry completely.
The installer must verify that the existing epoxy floor is firmly bonded to its substrate before recoating. This evaluation includes:
Only well-bonded, structurally sound areas are suitable for recoating.
If the existing epoxy floor is not properly prepared or is not firmly bonded to the concrete substrate, nothing can prevent that old layer from releasing. If the old epoxy lifts, the new epoxy will lift with it — regardless of how strong the bond is between the new and old coating.
It is the installer’s responsibility to confirm that the existing floor is prepared correctly, sound, and well bonded before applying any new Epoxy.com materials.
All loose, soft, delaminated, or deteriorated epoxy must be removed. Grind, scrape, or chip back to firm, well-adhered edges. Weak material left on the surface will undermine the new coating system.
After removing unsound material, repair all defects with:
Epoxy Gel – Product #2704 (Super Fast Cure)
#2704 is ideal for:
Allow repairs to fully cure before mechanical profiling.
Existing epoxy must be mechanically abraded to remove gloss and create profile. Accepted methods include:
The goal is to produce a uniform, de-glossed surface with enough mechanical “tooth” to ensure proper adhesion. Chemical etching is not acceptable for existing resin floors.
Before installing new epoxy:
Recoating must be done with a compatible Epoxy.com system chosen for the intended service conditions.
