QuartzLock2 RapidCure Urethane Grout is a next-generation eco-friendly grout technology that makes grouting tile easier, safer and more long lasting. Quartzlock2 is a non-toxic urethane which is low odor (when wet) and odorless upon curing. QuartzLock2 comes pre-mixed and ready-to-use in either a 9 lb. or 18 lb. bucket. (The one and two gallon buckets will not be 100% full. This is normal). Use it on all ceramic, porcelain and natural stone tile indoors or outdoors and even in submerged applications. Once applied, the grout cures to a very hard, self-sealed, semi-elastic finish which results in a colorfast grout that's resistant to chemicals, stains, mold and mildew. Plus, QuartzLock2 won't shrink or crack.
NOTE: Quartzlock2 contains crystalline silica, (ground quartz or sand). However, the crystalline silica is bound in a polymer matrix; it cannot become airborne and inhaled under normal use. According to the state of California, repeated and prolonged exposure to high levels of respirable crystalline silica MAY lead to lung disease called silicosis and/or lung cancer. Unlike traditional grout, the crystalline silica contained in Quartzlock2 grout, as delivered, is not respirable and cannot be inhaled. Crystalline silica can only cause lung damage if inhaled. When cured, sanded or abraded, this grout will not crumble, crack or produce dry dust. The use of abrasives will only result in the creation of a gummy residue without the dust-producing potential of conventional grouts.
TIP1: For successful application, instructions must be read and followed to the T. Please read to your contractor. No exceptions. The biggest mistake is to not clean with fresh water during application. We suggest using 4-5 buckets of fresh water and changing the water every 3-5 minutes during cleanup. Reusing dirty water will produce grout haze. It must be clean or the urethane will be left and cure on the surface of the tile.
TIP2: Don't overmix. There will be a big lump of solid product in the bottom of the container with liquid on top. Mix only by hand for 20-30 seconds just until mixed. We do not recommend using a drill. Mixing with a drill can cause the consistency to become too runny.
TIP3: Don't use any acidic cleaners including vinegar for at least a week after this product cures as it will damage the grout. Once cured neutral pH cleaners work best.
TIP4: How to remove grout haze. Follow Tip #1. QuartzLock2 offers a proprietary cleaner called Blaze which is recommended. See the accessories tab.
QuartzLock2 Urethane Grout is a great replacement/upgrade to epoxy, cement and pigment-based grouts. Unlike epoxy grout, it's much easier to apply and clean up; unlike pigment-based grout, there's no risk of incorrect mixing. Quartzlock2 comes pre-mixed and can be used a little at a time as needed. With epoxy grout, you must use the entire amount or it cures in the bucket. It also requires special sponges and clean up. The real bonus, however, is that QuartzLock grout never has to be sealed!
QuartzLock2 can be used for indoor or outdoor, commercial or residential, wet or dry and horizontal or vertical applications. It requires no water and it won't sag in vertical applications (as long as it is properly mixed) and won't dust. It's UV stable and non-allergenic; plus leftover grout can be saved for later use instead of being thrown in the dump.
Please Note: QuartzLock2 is NOT made to withstand temperatures higher than 140°F.
Forget dirty stained grout lines. Forget mold and mildew. Forget sealing your grout. One application and you are done forever. If you've ever used an epoxy grout, you know how hard it is to apply and clean up. This innovative non-staining grout removes all the pain and adds some great features. Contractors love this and you will too.
Alert: Warning! Do not use vinegar or acid-based cleaners as they will weaken the grout during the curing process.
