Hi Cataan. I went in to work last night and grouted the floor only of the Yale Town Condo Job I'm working on. We discussed the grout one more time and in the end made a last minute change. We decided since we like both the 100% white and the 75%-25% version to go in the middle. So I made up a 87.5% - 12.5% mix. A digital scale is needed for these measuring steps. I took some pictures for you so you can see how I go about it. I have more info on measuring at this blog post of mine: http://no-curb.blogspot.ca/2013/04/choosing-best-grout-for-your-no-curb.html I measured out 875 grams roughly of the white and then topped it off with the Sauterne until I hit roughly 1000 grams. This gives me the 87.5% - 12.5% blend. The two powders where dry sifted and blended and then I mixed up a small batch of the epoxy. I was a gram over on the first pour. with out resetting the scale I keep adding powder slowly. The fall rate gives a false read so you wait a second till the powder settles. I went a little over with the final dose. So we have a blend here now. I used two buckets and went back and forth with shaking to get all the powder evenly dry mixed. Then mixed up epoxy and added the powder. The epoxy grout installed so fast. These large tiles have almost no grout joints. You can see this picture is taken after I have forced the grout into the joints but before any of the cleaning passes. Epoxy is sticky. You can feel it on the sponge and on the tile. I do a first wash where I try and remove as much grout as possible from the tile without touching the joints. Then switch out the water and go to the Initial Wash package from Laticrete. I then tool the joints with the sponge and remove all the excess. Making sure the smear of Epoxy haze covers all the tile surface - everywhere. Then I take a break. Clean the buckets. Call my wife, my kids. Go for a walk and get a coffee and come back to do the final wash. This is one hour roughly from the application. So for me about 45 minutes after installation. I use a Micro fiber rag myself after I have cleaned the floor with the sponge. I find the micro finer rag does a better job leaving the floor spotless. You can screw up the grout joints this way if your not careful. But using the rags is the Cat's Ass I think. Now stay off the floor for at least 24 hours. Epoxy grout darkens a hair while curing. Cementiuos grout lightens. So this colour batch will darken a hair. You can see in the photo that is almost a dead ringer of a match right now.....

I have no idea what happened, but I'm getting far different answers today. So please ignore the above....in fact it was so bad, I deleted the comment. Below in order of closeness to the valspar... Valspar Blue Whisper BM Come Sail Away PPG Delicate Mist Behr Refreshed SW Crystal Clear

SW can match the color and may already have it in their system.

@Patricia ColwellYeah, I agree with you! We are now planning to just head to Kelly Moore and start from there. At first we weren’t sure which vendor we wanted to use, so we had different brands to consider. Now we’re settled on the Kelly Moore painter. The thing is, we already have BM Mascarpone in our family room and *love* it, so we thought we’d just continue that. Decision made - easy! 🙃 But yeah, it’s not that easy. Since theyre all so close, and appear different in different lighting, getting one that’s not BM‘s color isn’t a big deal. Now we just need to pick a soft white or cream for the walls and a good white for the trim and doors.
