Step 1: Prepare the Surface
A. Clean the Tile Joints
1.Remove old grout, dirt, or debris using a stiff brush or vacuum.
2.Wipe tiles with a damp cloth and mild detergent to eliminate grease or residue.
3.Let the surface dry completely (24–48 hours).
Pro Tip: Moisture compromises adhesion—ensure joints are bone-dry before applying epoxy grout sealant.
B. Protect Adjacent Surfaces

Step 2: Load the Epoxy Grout Sealant Cartridge
1.Insert Cartridge into Caulking Gun:
•Place the two-tube epoxy grout sealant cartridge into the dual-chamber caulking gun.
2.Attach the Mixing Nozzle:
•Screw the provided mixing nozzle tightly onto the cartridge.
Step 3: Prime the Epoxy Grout Sealant
1. Discard the First 5–10ml:
•Squeeze the caulking gun trigger until the epoxy grout sealant flows evenly from the nozzle.
•This ensures the resin and hardener are fully mixed.
2. Test Consistency:
•Check that the epoxy grout sealant has a uniform color and texture.
Step 4: Apply the Epoxy Grout Sealant
1. Fill the Joints:
•Hold the caulking gun at a 45° angle and slowly squeeze the trigger to inject the epoxy grout sealant into the tile joints.
•Work in small sections (3x3 ft) to maintain control.
2. Overfill Slightly:
•Ensure the sealant sits slightly above the tile surface for easier leveling.
Pro Tip: Move the nozzle steadily along the joint to avoid gaps or air bubbles.
Step 5: Level the Epoxy Grout Sealant
1. Smooth with a Leveling Tool:
•Immediately after applying, use a plastic scraper or leveling tool to press the epoxy grout sealant into the joints and remove excess.
•Work diagonally across the tiles for even distribution.
Critical Timing: Level the epoxy grout sealant within 90 minutes of application (check product guidelines).
Step 6: Cure the Epoxy Grout Sealant
1. Initial Setting:
•Let the epoxy grout sealant harden for 6–8 hours (10–12 hours in cold or humid conditions).
Step 7: Remove Excess Epoxy Grout Sealant
1. Scrape Off Residue:
•After curing, use a shaver or utility knife to carefully remove dried epoxy grout sealant from tile edges.
2. Full Cure:
•Avoid water exposure or heavy use for 24–48 hours.
