Types
Manufactured stone veneer (MSV): Made from cement, aggregates, and iron oxide pigments. Molded from real stone for authentic texture. Much lighter than natural stone (can be applied to wood-framed walls). Wide variety of styles: fieldstone, ledgestone, stacked stone, river rock, limestone, cobblestone. Consistent color and sizing (easier to install). Cost: $6-$15 per square foot (materials). Brands: Eldorado Stone, Cultured Stone (Boral), ProVia, GenStone.
Natural stone veneer: Real stone cut thin (3/4 to 1-1/2 inches thick). Authentic natural appearance and texture. Each piece is unique. Heavier than manufactured (may need additional wall support). More expensive and harder to cut. Cost: $12-$35 per square foot (materials). Types: bluestone, limestone, granite, sandstone, slate, fieldstone.
Faux stone panels (lightweight): Polyurethane or fiberglass panels. Ultra-lightweight (can be glued directly to surface). Easy DIY installation (no mortar, no metal lath). Less realistic up close. Good for interior accent walls and backsplashes. Cost: $8-$20 per square foot. Brands: GenStone, NextStone, Urestone.

Applications
Exterior: Entire home exterior (common in mountain and rustic styles). Foundation skirting (bottom 3-4 feet of exterior wall). Accent walls (front of home, chimney, entry columns). Porch columns and knee walls. Outdoor kitchen and fireplace. Retaining wall facing.
Interior: Fireplace surround (most popular interior use). Accent wall (living room, bedroom, dining room). Kitchen backsplash. Bathroom accent. Entryway or foyer. Bar or wine cellar.
Style options: Ledgestone: thin, stacked horizontal pieces. Modern and contemporary. Fieldstone: irregular shapes and sizes. Rustic and traditional. Stacked stone: dry-stack look (no visible mortar joints). Clean and modern. River rock: rounded, natural stones. Organic and casual. Limestone: uniform, cut blocks. Classic and elegant. Cobblestone: rounded, larger stones. Old-world and charming.
Installation
Exterior installation (manufactured stone veneer): 1. Install weather-resistant barrier (WRB) over sheathing (code requirement). 2. Install metal lath with galvanized nails or screws (over WRB). 3. Apply scratch coat: 1/2-inch layer of Type S mortar over lath. Score with notch trowel. Let cure 24 hours. 4. Dampen scratch coat and back of stones. 5. Apply mortar to back of each stone (1/2 inch thick, butter method). 6. Press stone firmly onto scratch coat. 7. Start from corners (use corner pieces), work from bottom up. 8. Grout joints if desired (use grout bag). 9. Brush joints for finished texture. 10. Seal with stone sealer (optional, recommended for exterior).
Interior installation (on drywall): Manufactured stone CAN be applied directly to drywall (for interior non-wet areas). Use construction adhesive plus mortar. Some MSV can be adhered with just adhesive (check manufacturer). Metal lath is recommended for heavy stone on drywall.
Faux panel installation (easiest): Adhered directly to surface with construction adhesive and screws. Panels interlock for seamless appearance. Cut with circular saw. Can be applied to drywall, plywood, or concrete.
Tips: Dry-fit stones on the ground before adhering (plan the layout). Mix stones from multiple boxes (varies color and size naturally). Corner pieces are critical for exterior applications (most expensive per piece). Allow mortar to begin to set before tooling joints. Protect finished stone from mortar smears (difficult to clean once dried).
Maintenance
Cleaning: Rinse with garden hose (low pressure). Mild soap and soft brush for stains. Do NOT pressure wash manufactured stone at high pressure (can damage surface). Avoid acidic cleaners on cement-based stone (damages surface).
Sealing: Exterior stone: seal with breathable stone sealer every 2-3 years. Prevents moisture absorption, staining, and efflorescence. Interior stone (near fireplace): optional sealer for soot protection.
Repairs: Loose stones: re-adhere with mortar or construction adhesive. Cracked mortar joints: re-grout with matching mortar. Color fading: manufactured stone retains color well (iron oxide pigments).
Lifespan: Manufactured stone veneer: 20-75 years (depending on quality and installation). Natural stone veneer: 50-100+ years. Faux panels: 10-20 years.
