Spectralock 1 Questions

--Does this leave a film on tile if it is not cleaned up fast enough?
--Also can you use it on textured tile? I read that some people have issues with a film on the Mapei Flexcolor CQ even if they cleaned it up quickly. This is espcially, but it sounds like not limited to problems with textured tiles.
--Also another bath I have will have mosaic pressed glass tiles. Any issues using this product with that? Staining or scratching?
--When grout is "sanded" like this, are there ways to keep it from scratching tiles? Like a lighter touch? Better sponges? Something like that or you just test it and see? The pressed glass tile is confusing - one instruction sheet says not recommended for sanded grout and the other says to use epoxy grout if prefer stain resistance (which I think is always sanded).
--I don't care about strength - to me all grouts will be fine in my residential bathrooms from a strength perspective. I only care about staining over time. I want the best grout that is stain resistent, but also that it can be installed easily enough because I don't want to risk a bad job from my contractor. All of my tiles are ceramic except one is pressed glass. Several of the ceramic ones have texture to them. Thoughts appreciated on this.
Thank you for your help and advice.

Welcome, Lauren.

You'll do better by starting a project thread of your own in the Advice forum where you can give us all the particulars of your project and your tiles, rather than asking project specific questions on this single product thread.

[Edit] 06-19-20 posts moved to new project thread, but OP has never returned.

CX makes a good point but I will weigh in on a few of your questions. I haven't worked with the Spectralock 1 but it seems like you're comparing it to the Flexcolor CQ with which I'm very familiar. The Flexcolor CQ has a rounded aggregate (think little beads instead of grains of sand) which makes it less prone to scratching your glass and soft ceramic tiles. Cleanup on textured tiles isn't really a big issue, it gets used on them all the time. If you do get a film, some Windex will usually do the trick. If it is really dried on, a citrus based cleaner like Goo Gone can remove the haze. Usually just rinsing with lots of clean water when you're in the cleanup stage is enough though. Unlike with cement based grouts, you can't wash the pigment out of Flexcolor CQ because it's bonded to the aggregate. Based on the TDS it appears that Spectralock 1 develops more early (24 hour) strength. It also tends to be more expensive, close to the cost of a true epoxy grout. If you don't need the extra early strength or epoxy chemical resistance, you would probably be better off with the Flexcolor due to the rounded aggregate.

Thank you for your help. I only care about the staining from chemicals or soaps or dirt or mold. So does that mean an epoxy or epoxy -like is the solution? I don't want to be sealing every year. Is the Flexcolor CQ good against stains? I would still love to hear from someone on the Spectralock 1. Thanks so much

Can't comment on SL1, but I have used Spectralock epoxy grout and love the stuff. It is nearly bullet proof. If staining is a concern that's what I'd go with, a proven track record.
If I recall correctly my memory is excellent, but my ability to access it is intermittent.

DIYer: Used Spectralock 1

I used this based on Sal DiBlasi's Youtube video. Okay, so that was marketing. I am in the dry Southwest, and it dries very, very quickly here in no-humidity land. It was very mica-like, meaning there are sheet-like bits of plastic (or something) in it perhaps. (We used Dusty Grey. In the container, it is a darker gray. On the floor, it is a browner gray. We also used Sterling Silver which was pretty true to color for the gray cement-looking shower tiles.) We found it worked best with two of us working together, since it dried so fast. The dryness also made it less easy to spread, so I found sprinkling a few drops of water over the tile before putting down the grout helped make it smoother. We have been using the shower where I grouted, and there have been no problems, but it has only been a few months. I used Mapei UltraFlex Plus FA to do a backsplash recently, and I LOVE that grout much more. I bought that to put into our other shower. I did my own comparison between the two grouts, and the Mapei dried SO MUCH harder. Also I can seal the Mapei, and I plan to use 511 Impregnator which is solvent-based (per Mapei recs).

Amateur here. Just did my first ever tiling job on my bathroom. I used Spectralock 1. I’m located in NJ. I really liked the product, but I have nothing else to compare too as that’s the first grout I ever used haha. But I liked the premixed aspect to it, and the strength they are touting. Have a lot of clean water for cleaning. Also the instructional video says the second coat needs a doddlebug or whatever they call it to scrub off the residue. I had something similar I used. I keep it for stubborn stains on the interior of my car. I highly recommend that, it did the best work by far.

This stuff dries really really fast. So don’t apply more than you can wipe down in 5-7 minutes. Check my post history for pics of it. I think I posted a pic of me testing the grout on a test board. Good luck!
