Spectralock vs Opticolor Epoxy Grouts

I have used the spectralock epoxy grout for over 2000 ft2 of tile in bathrooms, living rooms, and walls around our house. The grout has lived up to its billing and then some. Our 5 year old was sick and didn't get to the toilet in time when throwing up. The grout cleaned up perfectly.

For big jobs I buy commercial size units, and for small projects I used to buy the mini kits from lowes. Lowe's has since switched to mapei's epoxy grout, and I hope someone has some experience to compare the two products.

(1) Mapei's instructions don't include much information about cure time vs temperature. Spectralock's instructions were very detailed in this respect and if I remember correctly the curing time for full stain resistance is generally 3 to 7 days depending on the temperature, and perhaps as long as 14 days if the temperature is very cold. Does anyone know if Mapei sets up and becomes stain resistant at a quicker or slower rate compared to spectralock?

(2) I had very good results to clean up spectraock when i intially washed with 2 cups white vinegar mixed into 3 gallons of water about 30 - 45 minutes after I started the grout application. I then did a final wash with water alone about 30 minutes after the first wash. Mapei's instructions suggest that water alone will work. Would persons recommend to use only water with Mapei's product or to mix some white vinegar into the initial wash water.

(3) Mapei's instructions sugest that excess water can leave a permanent film on the grout. Is the mapei product more prone to water damage than spectralock?

Thanks for any help.

Ham, I haven't used Spectralock but I did grout my shower last weekend with Opticolor. I cleaned it with plain water but the spots that I missed I cleaned up with a vinegar solution a day later. Mapei suggests that you not leave excess water lying on the tile surface as in flooding a floor. They don't mention the use of vinegar for cleaning and I don't think it's necessary for the initial cleanup. The vinegar was very effective the next day however.

I'm currently using Opticolor in my bathroom, and it's stellar. I actually find it easier to work with than cement grout. So much so that unless I have some specific reason such as $$ because of too much sq footage, I'm going to use it for the rest of my tiling jobs.
