Steve Brookins says...

Spent more money than we had planned on spending for grout. But are very happy with the results!!! At first it was a little difficult to apply the grout compared to traditional grout.....but every batch got easier and easier to use. It looks and feels great....so happy we made the decission to use Spectralock....time will tell....hope to never see mold in the tub area that we used this in. It looks beautiful!

John Trent Tile & Stone says...

SpectraLock Pro Grout is a fantastic grout! The color consistency can't be beat and the protection it offers against staining is bullet proof. We use it in all our pool applications - Thanks Laticrete!

Great website for getting submittal and O&M information. The process is long enough without complicating it, but you made it much easier to work with. Thanks Laticrete!

We have been using this product for years. Easy to use & durable. Many of our shower installs are with natural pebbles, Jeff Madson, our lead installer will use nothing but Spectralock on them.

I have been using Laticrete epoxy grouts exclusively for years now. It makes only good sense to use the best grout in any curcumstance, and Laticrete has it!!!
