Frequently Asked Questions

Q

How much does DIY terrazzo cost per square foot?

DIY terrazzo typically costs $5–$15 per square foot for materials, depending on the aggregate type and resin choice. Professional terrazzo installation ranges from $20–$80 per square foot.

  • Epoxy resin: ~$45/gallon covers roughly 12 sq ft at 1/8" thick
  • Marble chips aggregate: $8/lb, the most affordable option
  • Mother of pearl aggregate: $25/lb, premium look at 3x the cost
  • Sealant: $25/quart, plan for 2–3 coats minimum
  • Polishing supplies: ~$30 one-time investment for sandpaper set

Q

Should I use epoxy or cement-based terrazzo?

Epoxy terrazzo is better for DIY countertops and small projects because it cures faster (24–72 hours) and is easier to work with. Cement terrazzo is cheaper but requires 7–14 days to cure.

  • Epoxy cures in 24–72 hours, cement needs 7–14 days
  • Epoxy costs ~$45/gallon, cement is ~$15 per 50lb bag
  • Epoxy is non-porous and stain-resistant without sealing
  • Cement terrazzo is more traditional and heat-resistant
  • For countertops and tables, epoxy is the clear winner for DIY

Q

What aggregate density should I use for terrazzo?

A 40% aggregate density is the standard for most terrazzo projects, giving a balanced look with visible chips throughout. Use 20% for subtle accents or 60% for heavily speckled surfaces.

  • 20% density: subtle, resin-dominant look with scattered chips
  • 40% density: classic terrazzo look, most popular choice
  • 60% density: heavy aggregate, dramatic mosaic appearance
  • Higher density uses more aggregate but less resin
  • Test a small sample first to preview the final look
Q

How do I polish DIY terrazzo?

Polish DIY terrazzo by wet sanding through progressively finer grits from 200 to 3000, then apply a polishing compound. The process takes 2–4 hours and costs about $30 in supplies.

  • Start with 200-grit sandpaper to level the surface
  • Progress through 400, 800, 1500, and 3000 grit
  • Always wet sand to prevent dust and scratching
  • Finish with a polishing compound for high gloss
  • A full sandpaper set (200–3000 grit) costs about $30
Q

How much aggregate do I need for a terrazzo countertop?

For a standard 48" x 24" countertop at 1.5" thick and 40% aggregate density, you need approximately 4–5 pounds of aggregate chips. The exact weight depends on the aggregate material density.

  • Volume formula: Length × Width × Thickness × Density%
  • Marble chips: 2.7 g/cc density, heaviest common aggregate
  • Recycled glass: 2.5 g/cc, slightly lighter than marble
  • Buy 10–15% extra for mixing losses and test pours
  • Smaller chip sizes (1/4"–1/2") are easiest for DIY projects
