How to Seal Around an Existing Floor Drain with Epoxy.com Systems
Updated May 2025 with improved product recommendations and application tips.
The Problem
“I have a second-floor production area that has a long stainless steel trench drain around the center of the room. We hose the area down with hot water, but a crack is developing next to the drain that allows water to leak into the room below. The floor under my quarry tile is concrete.”
The Solution
Here’s how to permanently seal around a stainless steel drain using Epoxy.com Products #660, #10, #82, and #2 for industrial-grade waterproofing and chemical resistance.
Step-by-Step Instructions
1. Remove Surrounding Tile
Carefully remove the quarry tile around the perimeter of the floor drain.
2. Clean Back to Bare Concrete
Remove all grout and thinset to expose clean, sound concrete.

3. Undercut or V-Groove the Concrete Edge
- Cut or chip a V-groove around the drain
- Increase bonding surface for epoxy
- Avoid cutting through the slab
4. Abrade the Drain Edge
- Roughen stainless steel to remove shine
- A dull surface improves bonding
5. Clean Thoroughly
- Vacuum loose debris
- If using air, ensure it’s oil-free
6. Prime the Drain Edge
Apply Product #660 – Aluminum Filled Primer.

Mix and apply neat (resin + hardener only) Product #10 to all concrete and primed metal surfaces.
8. Install Epoxy Mortar
Mix Product #10 with Product #82 Mortar Aggregate.
Trowel into the cleaned drain perimeter and smooth flush. Let cure overnight.
9. Seal the Surface
Apply a squeegee coat of neat Product #10 to fully seal the repair area.
10. Allow to Cure
Let cure for 10–12 hours at 75°F.
11. Topcoat with Product #2 + Anti-Skid
Apply Product #2 – Chemical Resistant Epoxy Coating with Anti-Skid Additive.
12. Apply Second Coat
Repeat Step 11 for added durability.
