Do's
Tell Client to allow to cure for 72 Hours before using in a shower or tub
Get Color approval...especially from the picky clients. Undersell how well the color is going to match (we dry mix and show them it will be close to that color but not exact)
Put "kits" together with plastic cups, syringes, mixing stick(s) or putty knife
Wear gloves (I like (wife likes) my hands nice and soft... despite the "Caulk" paronomasia I'm a flaming hetorosexual
Have various grout colors (We mix colors to get within "10-15%" match (*part of my turn on to this product is not having to stock a ton of silicone colors anymore...WAY LESS WASTE)
Mix it extra thick for big vertical gaps and/or do those gaps LAST. The product will start to firm up so do the horizontal surfaces 1st.
Be Patient. If there's a lot to do and you're on your own only mix up what your going to use. I've mixed up too much before on big jobs (over confidence) and wasted material. I HATE waste (see Paul Aker's 2 Second Lean)
I can actually silicone/caulk faster than I can SGA on most jobs, despite this, I know this product outlasts silicone.
Have a small plastic garbage bag for throwing away the empty bottles, gloves, sticks etc.
Mix over a towel or drop clothe
Prep area properly, Mix thoroughly
Dont's
Make a mess. I've had one of my guys leave a chunk of this on a clients door knob, chunks in tubs, sinks, etc. Make sure you clean up well. If you get this stuff on your pants/clothing it's tough to get off once it's cured.
Breathe in a bunch of grout dust. Silica sand is bad. A respirator isn't a bad idea.
Don't eat it.
If you live in Kitsap County Washington, don't use it. It won't cure properly
