Design Methods

Method Best For Skill Level Time Required Materials Needed
Direct Method Small projects, beginners Beginner 1-3 days Substrate, adhesive, tesserae
Indirect Method Large murals, detailed work Intermediate 3-7 days Paper, reverse planning
Double Indirect Complex installations Advanced 5-10 days Multiple transfer stages
Opus Vermiculatum Figurative work Advanced Weeks-months Fine tesserae, patience
Opus Tessellatum Geometric patterns Intermediate Days-weeks Uniform pieces, grid planning

Common Mosaic Patterns

Pattern Name Difficulty Visual Effect Best Applications Tesserae Shape
Running Bond Beginner Linear, structured Borders, backgrounds Rectangular
Herringbone Intermediate Dynamic, textured Floors, feature areas Rectangular
Basketweave Intermediate Woven appearance Traditional designs Square + rectangular
Fan Pattern Advanced Flowing, organic Decorative panels Varied shapes
Opus Palladianum Intermediate Natural, random Stone mosaics Irregular pieces
Andamento Advanced Directional flow Figurative work Follows form

Surface Preparation

Substrate Type Preparation Required Primer Needed Suitable Adhesive Indoor/Outdoor
Plywood Sand, clean, seal Yes PVA, cement Indoor only
Cement Board Clean, check joints Sometimes Thinset, epoxy Both
Concrete Clean, etch if smooth Sometimes Thinset, epoxy Both
Drywall Prime, check stability Yes Mastic, PVA Indoor only
Metal Clean, roughen surface Yes Epoxy, silicone Both
Glass Clean thoroughly No Silicone, epoxy Both

Colour Theory for Mosaics

Colour Concept Effect Application Tips
Complementary High contrast, vibrant Focal points, drama Use sparingly for impact
Analogous Harmonious, peaceful Backgrounds, gradients Creates smooth transitions
Monochromatic Unified, sophisticated Subtle designs Vary textures for interest
Triadic Balanced, lively Complex compositions One dominant, two accent
Neutral Base Grounding, versatile Large areas Add pops of colour strategically
Temperature Warm/cool contrast Depth, mood Warm advances, cool recedes

Project Sizing Guide

Project Size Time Estimate Skill Level Recommended Materials Typical Applications
Coaster (4”) 2-4 hours Beginner Small glass tiles Gifts, practice pieces
Trivet (8”) 4-8 hours Beginner Ceramic, glass mix Functional art
Garden Stone (12”) 8-12 hours Intermediate Weather-resistant materials Outdoor decoration

Maintenance & Care

Surface Type Cleaning Method Frequency Sealant Needed Special Considerations
Indoor Decorative Mild soap, soft cloth Monthly Optional Avoid abrasive cleaners
Kitchen Backsplash Degreasing cleaner Weekly Recommended Food-safe sealants only
Bathroom Mold-resistant cleaner Weekly Yes Focus on grout lines
Outdoor Garden Pressure wash, scrub Seasonally Yes Freeze-thaw protection
Pool/Spa Pool chemicals As needed Specialized Chemical-resistant materials
High Traffic Regular mopping Daily-weekly Yes Durable, sealed grout

Troubleshooting Common Issues

Problem Cause Prevention Solution
Grout Cracking Movement, wrong mix Proper substrate prep Remove, re-grout affected areas
Tiles Falling Off Poor adhesion Clean surface, right adhesive Re-attach with proper adhesive
Uneven Surface Thick adhesive application Use notched trowel Sand high spots when cured
Grout Discolouration Staining, efflorescence Seal grout properly Clean, re-seal, or re-grout
Lippage Uneven tile thickness Sort tiles by thickness Grind down or build up as needed
Haze on Tiles Grout residue Clean while working Acid wash (carefully) or polish

Safety Considerations

Hazard Type Risk Level Protection Required Safety Measures
Glass Cutting High Safety glasses, gloves Proper disposal of shards
Dust Inhalation Medium-High Dust mask, ventilation Wet cutting when possible
Chemical Exposure Medium Gloves, ventilation Read all product labels
Sharp Edges Medium Cut-resistant gloves Handle carefully, sand edges
Heavy Lifting Medium Proper technique Use helpers for large pieces
Repetitive Motion Low-Medium Ergonomic tools Take regular breaks
