Revolutionary pre-mixed, self-sealing, stain-free grout

QuartzLock2 Urethane Grout is a next-generation eco-friendly grout technology that makes grouting tile easier, safer and more long lasting. Made with a ultra-low odor non-toxic urethane, QuartzLock2 comes pre-mixed and ready-to-use in either a 9 lb. or 18 lb. bucket. 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.

TIP: For successful application, instructions must be read and followed to the T. 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.

How to remove grout haze. 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 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.

This is an encapsulated product in which the sand component (crystalline silica) is bound in a polymer matrix. The sand contained in QuartzLock2 cannot be inhaled under conditions of intended product use.

How much do you need? See the coverage chart on page 4 of this guide.
On the Installation and Coverage Chart, the 9 lb. unit corresponds to the 1-gallon size; the 18 lb. unit corresponds to the 2-gallon size.

For glass and metal tile, we recommend the use of StarGlass Grout, also by StarQuartz.

Why we like it

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.
