what is the coverage of 1 gallon?

This is dependent on the dimensions of the tile you are using and the joint width desired. Please reference the "Manual" PDF on the page, as it contains a breakdown chart in regards to coverage.

Is this grout waterproof?

No, it is not waterproof. You will need to look at the porosity rate of the grout. Laticretes Pro Premium Grout has a porosity rate of less than 1%, while the Spectralock PreMixed Grout has a porosity rate of less than 3%.

Can you use a refillable caulk gun to apply to tile seams. Is the grout sanded or un-sanded?

The SPECTRALOCK 1 Pre-Mixed Grout is too thick to be put in a caulk gun and is recommended to be spread like normal grout. This is sanded Grout.

Additional Info

Great product, awesome company!

I have found the SpectralocK is the best alternative to 3 part epoxy. After watching a few videos from Laticrete, others in the trade who have used it and from personal experience, I have determined this is my go to for grout Not a replacement for steam showers or for shower floors.... otherwise its the best I have found so far. Nothing quality is ever inexpensive. Contractors Direct is the best source which saves me time, money and is convenient. They always update me on order status and delivery.

Great!

Great one step product. No more mixing 2 parts. Went down smooth and cleaned up great

Easy ordering

Ordering was easy and it arrived quickly with no issues.

take your time.

Works stiffer than normal grout in tight joints and does take twice as long to grout shower. But does clean up good if you don't try to do to much at a time.

Great product

Super fast shipping. Great product. We have used it many times.
