Questions & Answers
3 questions

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.

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.

Is this grout waterproof?

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

Great product, awesome company!

by Rob H -

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.
