Step 1: Planning & Preparation
1. Review Local Building Codes
Check permit requirements
Verify footing depth and structural requirements
Confirm railing height regulations (typically 36")
2. Design Considerations
Plan board direction (parallel, diagonal, or picture frame patterns)
Calculate material quantities (add 10% for waste)
Mark utility lines before digging
Step 2: Building a Rock-Solid Substructure
1. Joist Installation
Space joists 12-16" on center (verify with DOMI specifications)
Use #10 x 3" structural screws for connections
Apply DOMI joist tape to all framing members
2. Proper Deck Slope
Create 1/4" per foot slope for drainage
Maintain 1/2" gap between deck and house
3. Special Considerations
For elevated decks: Install blocking between joists
In snowy climates: Reduce joist spacing to 12"
Step 3: Installing DOMI Deck Boards
Option A: Hidden Fastener System (Recommended)
- Install starter clip at house side
2. Insert first board with 3/8" expansion gap
3. Secure with DOMI hidden fasteners every 12-16"
4. Maintain consistent 1/4" gap between boards
Option B: Face Screw Method
- Pre-drill all screw holes
2. Use DOMI color-matched screws
3. Fasten at 45-degree angle into joists
4. Keep screws 1" from board ends
