Ordering color sealer quantity depends on how much grout you have.
Generally, a 4 oz bottle will cover 600 square feet of 12 inch tile with 1/4 inch grout line. If tiles are smaller than 12 inch, then the 4 oz bottle will not cover as much area. Likewise larger tiles will allow you to cover a larger area.
About our sealer
Our sealer is a protective sealant and color in one! It is our own company formula that we provide in a variety of colors. Its chemical makeup is eco friendly. Once the sealer is completely dried and cured, you will find that the bond is nearly unbreakable!
Colors render on monitors and cell phones differently. Use for general/approximate reference only. Color swatch cards are the most accurate way to select color and are available at any contractor supplier of tile and grout. (Home Depot, Lowes, etc)
