Quartz-Lock® Grout is a READY TO USE Urethane grout.
• DO NOT add any water, liquid or other material to QuartzLock® Grout!
• Liquid may be present on the surface of the grout when opened. This is from normal settling in shipment. Use a margin trowel to fold the liquid into the grout.
• Prepare two 5 gallon buckets of cleaning water. Add a 2 oz bottle of StarClean additive (provided with each bucket of grout) to one of the buckets. This water will be used for final cleaning.
• After surfaces are cleaned (and sealed, if necessary), let surfaces dry thoroughly before grouting.
• Spread the grout using a sharp-edged, firm rubber grout float. Work the grout into the joints, packing them full.
• Remove excess grout off the tile surface using the edge of the float like a squeegee, pulling diagonally to avoid pulling grout out of filled joints.
• For best results, remove grout haze AS YOU WORK, particularly in warm or dry climates. If working alone, only grout as far as you can reach before cleaning.
• Use 5 gallons of clean water with a sponge to clean up excess grout as you work. Rinse clean sponge in water and wring until damp. Change water mixture after each 100 square feet or when dirty.
• Keep the sponge flat; lightly wipe grout and tile surface, loosening grout residue while making the joints smooth.
• Rinse sponge after every pass; use each side of sponge only once between rinsing. Check work as you clean. Repair any low spots with additional grout. Unlike other grout, DO NOT wash too vigorously.
 • After the tile surface dries following the initial clean, wipe the tile to remove any excess grout or haze using second 5 gallons of water with the StarClean additive.
• Like before, keep the sponge flat; lightly wipe grout and tile surface with a clean damp sponge. Use each side of sponge only once before rinsing thoroughly.
• One 5 gallon bucket of cleaning water is sufficient for each 18 lb bucket of grout.
• Allow cleaned areas to dry and inspect tile/stone surface. For persistent grout haze, after grout has cured, scrub tile with mixture of StarClean and water.
• Protect finished surface from light traffic for at least 24 hours at 70°F (21°C). Complete cure requires 72 hours at 70°F at 50% relative humidity. For wet areas, like showers, wait 7 days before use. Do not expose grout to stains or cleaners for 7 days. For outdoors applications protect grout from moisture for 72 hours.
• For use in joints 1/16” or greater. i.e. (12x12, ¼” joint = 126 sq ft/18 lb. unit) For additional coverage information consult product technical bulletin or visit www.starquartz.com.
• Use an approved waterproof sealer for Mud bed applications 24 hours prior to setting tile.
• If needed, cover only with breathable paper.
• Call StarQuartz industries before using Quartz-Lock Grout in the following applications; pools and hot tubs.
• Use product in temperatures above 40º F. If product freezes return to room temperature and use as directed.
• Do not use solvent based adhesives or sealers.
• Always use protective clothing (gloves and eye protection) when working with grout.
