First, no mixing, so no color variations. Epoxy needs mixing also...and is messy. Any leftover can be re-sealed and used for another project later on. No sealer needed. Good color. I've seen white used on a test board... two hours later, splashed mustard, wine and coffee over it and wiped up clean with a damp sponge. A little learning curve for application~ Do small areas at a time. Fill joints well. Slightly dampen tiles before application. Using a WELL wrung out sponge, clean the area in a circular motion within a minute or so of application. I like to use either a microfibre-backed sponge or a sponge with a well wrung out microfibre cloth wrapped around it to make single passes over the area within a couple of minutes. Go on to the next area. An hour or two later, just buff off any haze with a dry or almost dry microfibre towel. Two people working together make it go very easy....although one can do it. Remove any rings and wear some disposable gloves....Fusion Pro loves skin, as well! Once done, you should never need to do anything else to it other than general cleaning.

Go to the Laticrete web site to get the final word. But this is what I understand. SpectraLock is an epoxy grout, meaning that it has a part A and a part B that is mixed (like epoxy) and then the colored sand is added. It is durable and stainproof. There are 2 formulations of SpectraLock, the Pro (at Lowes) and the Pro Premium. I have heard that while they are both epoxy there is a slight difference in the color out come and they should not be used next to each other (in the same grout job) because the grouts will be slightly different in color. I have also heard that the Pro Premium is supposed to have better spreadability. Laticrete has a regular cementous grout product called LATICRETE PermaColor. I do not think that Lowes carries this any longer. I have heard from Bill V. on this site that this is a very fine product. I have just finished grouting my slate bathroom floor and used the SpectraLock Pro Premium that I ordered online with great success. The site I ordered from was linked on the Laticrete site as a distributor. This is their web site and I was very happy with the packing and shipping time frame. http://www.tilestoreonline.com/default.asp I got the "full unit" without the bucket for $43.70. I can't remember if shipping is free. Anyway, got the grout, and with my 1/4 grout margins, I got about 45-50 sf out of this "full unit" - about what I predicted using Laticrete's grout estimator. I have read that epoxy grout is hard to use for some people. I did not find it to be difficult, but I don't have much to compare it to. I followed the instructions to the "T". Except I learned on the JB forum from a poster, that you can freeze the epoxy and take it out later for patches. So, I took a zip lock bag and put about a 1/2 cup of the grout in to it, smashed it to about the thickness of a pancake, zipped it shut, and froze it. A few days later I found a few divots in the floor where my toes or fingers may have pushed in, as I was grouting. I broke of some pieces of the frozen grout and it thawed very quickly. I smeared it into the imperfections, then waited 20-30 minutes. I then went over it with a damp sponge rinsed and rung out in a few cups of H2O mixed with a few TBS of white vinegar. In other words I used the same cleanup procedure that I was instructed to do with the initial installation of SpectraLock. Except I didn't have the "rinse" product. I had read on the JB forum to use vinegar in the water and this will work as a rinse. After it fully dried I could not see any difference between the small patches and the original installation. I plan to use SpectraLock Pro Premium on my walls too when I get them tiled. Here is a link that might be useful: Laticrete web site

How abobut the fact that if there's a problem that developes, even initially, nevermind over time, that Custom Building products has built itself a reputation for making sure they find any and all reasons why it's not their problem, while Laticrete has built just as strong a reputation for standing behind their products, no matter the cost. It's the biggest reason why I'm such a strong supporter for the use of their products. I've done projects in the past, one, in fact, that cost them dearly, where there was a failure, and they covered every single penny, from demo, to reinstallation, to all materials, including the tile itself. THAT, is a company whose products I want to use.

Hi. I usually post at the Pet Forum on this site, and I know that this is an old thread, but I just want to add another thumbs up for ThisOldGrout.com. I had a porcelain tile kitchen floor installed last month and chose Laticrete #34 Sandstone to bring out the color and define the joints of the diagonal tile (I have a long narrow galley kitchen). The grout came out several shades lighter and a different shade than the colorcard...more of a pinkish beige than a mauve-taupe. Yuch. Both Laticrete and the tile store suggested an Enhancing Sealer to darken the grout. I bought some locally(AquaMix's)and tried a small hidden area. It did darken the grout slightly but not much. I called Aquamix's Tech Support line ...they told me something important: That they could not guarantee color consistancy with the Enhancer and once it was applied, nothing could be done to correct any color inconsistancies. They suggested I try a small sample of their grout paint. Unfortunately, neither of the 2 paint samples I ordered hit the right color...a shame because folks had good things to say about AquaMix paints. I did another web search and came up with this thread and the ThisOldGrout suggestion. They also have good tech support (they don't try to over-sell you). I ordered the colorant. It came out great...exactly the Laticrete color I wanted. It was relatively easy to apply. I did mask around the joints for a clean line that didn't need scrubbing. It doesn't have an odor and dries quickly. The color is perfectly consistant. I hope it stays that way. Thank You Joang for the suggestion. LF
