Simple 4-Step Construction Process

Achieve perfect caulking results with five easy steps, no complex skills needed:

Prep the Tile Joints: Thoroughly clean tile crevices with a utility knife or joint cleaner, removing all dust, debris, and loose particles to ensure a completely dry, dust-free surface for maximum adhesion.
Apply the Grout Evenly: Load the grout into a caulking gun and dispense at a steady, consistent speed, filling joints fully to eliminate gaps or air bubbles.

Smooth & Level the Joints: Use a joint indenter ball to press and flatten the freshly applied grout, creating a uniform, seamless finish while ensuring full contact with the tile edges.
Remove Excess Grout: Once the grout has reached its initial cure stage (typically 30–60 minutes, depending on temperature), scrape off residual material from tile surfaces with a dedicated grout scraper, then allow the grout to cure fully for long-lasting durability.

Storage & Safety Guidelines

Store unopened products in a cool, dry place at 5℃–27℃ and 30%–70% humidity, with a 12-month shelf life. Do not return unused materials to original containers to avoid contamination. Wear protective gear during construction; rinse with clean water immediately if contacting skin or eyes. Keep the product out of children’s reach and refer to MSDS for full safety details.
