(5 reviews) Write a Review


At last! Grout that was designed for stained glass mosaics! This reclosable jar of raven black grout comes in powder form. Just mix with a little bit of water and it's ready to go. Instructions are on the back of the jar. Not suitable for freezing temperatures.
Each jar contains 1 1/3 cup of dry grout. Coverage per jar: 2 1/3 square feet of mosaic with 1/2" x 1/2" tiles spaced 1/8" apart. (Coverage may vary based on tile size and spacing. If you use larger tiles, less grout will be necessary. If you have larger spaces, more grout will be necessary.)

Books & tools are not subject to further discounts. U.S. shipping only.

    I used this product to complete a detail in a large garden mosaic in my patio. I worked great, exactly what I wanted.
