FAQ
Common questions
How much does a first mosaic project cost?
Around $55-80 for the complete first-time kit: wheeled nippers (~$20), Weldbond adhesive (~$12), a glass tile variety pack (~$20), sanded grout (~$10), and a small wood panel (~$8). The tools last for years; you only restock tiles and grout.
Can I use floor tiles or leftover tile from a hardware store?
Yes, with caveats. Glazed ceramic floor tile works fine but cuts less cleanly than mosaic-specific tiles, and the glaze can make adhesion tricky. Avoid porcelain tile as a beginner, it's much harder to cut and will destroy your nippers quickly.
Do I need a special workspace for mosaics?
Any stable table works. Put down a silicone mat or cardboard to protect the surface. You'll generate tile chips when cutting, work on a tray or inside a shallow cardboard box to contain them. Good lighting matters more than dedicated space.
What's the difference between sanded and unsanded grout?
Sanded grout is for gaps 1/8 inch or wider, the standard for most mosaic work. Unsanded grout is for narrower gaps or polished surfaces that sanded grit would scratch. Start with sanded for vitreous glass or ceramic tesserae with standard spacing.
How long does a mosaic take to make?
A 6×8 inch piece takes 3-5 hours spread across a weekend: an hour for cutting and layout, an hour for gluing, 24 hours of adhesive cure time, then 30 minutes for grouting and cleanup. The cure time is waiting, not work. Your first piece will be done before the next weekend.
Can I put a mosaic outside?
Yes, but you need thinset adhesive (not Weldbond) and exterior-rated grout. Weldbond fails when it freezes. For outdoor pieces, use polymer-modified thinset and seal the finished grout with a silicone-based sealer annually. A properly made outdoor mosaic can last decades.
