Frequently Asked Questions
How many mosaic tiles do I need?
Divide your project area by the tile area (including grout gaps), then add 10 to 15 percent for breakage and waste during cutting.
What size mosaic tile is best for beginners?
Three quarter inch tiles are the most versatile for beginners. They are large enough to handle easily but small enough for good detail.
How much grout do I need for mosaics?
Grout amount depends on gap width and tile thickness. A general rule is about 0.5 ounces per square inch of grout area for standard craft mosaics.
