📐 ​​Step-by-Step Install Guide​​

✅ ​​Step 1: Measure Your Space​​

​​Use this simple math:​​
​​Panel Count = (Wall Width × Wall Height) ÷ Single Panel Size + Extra for Errors​​

• Example: 8ft wide × 5ft high wall = 40 sq.ft
• One panel: 2ft x 8ft = 16 sq.ft
• 40 ÷ 16 = 2.5 → Buy 3 panels
• Add extras: 3 × 1.15 = ​​4 panels total​​

💡 ​​Smart Tip:​​ Buy matching ​​PVC corner pieces​​ for neat edges!

✅ ​​Step 2: Cut Panels Correctly​​

See our Easy PVC Cutting Guide for details
​​Key Cuts for Bathrooms:​​

• ​​For Faucets/Pipes:​​
  1. Trace fixture shape onto cardboard
  2. Copy shape onto panel back
  3. Drill starter holes → cut with jigsaw (use down-cut blade)
• ​​Sloped Ceilings:​​
  1. Hold panel in place
  2. Mark angle using angle tool
  3. Cut with circular saw (turn blade upside down for smooth edge)

✅ ​**​Step 3: Add Moisture Protection

(SKIP THIS = MOLD RISK!)
​​Best Methods:​​

1. ​​Over Drywall:​​
   • Hang thick plastic sheeting (6 mil)
   • Overlap edges 6″ → seal with waterproof tape
2. ​​Over Concrete:​​
   • Paint on rubbery waterproof coating (like RedGard)
   • Add 2 coats with tape at corners
3. ​​Shower Areas:​​
   • Add cement board before waterproofing

✅ ​​Step 4: Apply Glue​​

​​Bathroom-Specific Tips:​​

1. Use ​​strong liquid glue​​ (like Wedi Joint Glue)
2. Spread with notched tool:
   • Vertical lines: 12 inches apart
   • Border: Continuous line
3. ​​Warning:​​ Keep glue away from edges!

🌡️ ​​Temp Alert:​​ Glue won’t stick well below 50°F → Warm room first

✅ ​​Step 5: Hang Panels Right​​

​​For Perfect Fit:​​

1. Start at inside corner (usually shower end)
2. Press first panel firmly with rubber hammer
3. Check level often → use wedges to adjust
4. Leave small space between panels
5. Install ceiling panels last
6. ​​Press Firmly:​​
   • Press center → push out to edges
   • Roll diagonally with a roller

✅ ​​Step 6: Seal & Finish​​

​​Stop Mold:​​

1. ​​Seal Joints:​​
   • Use mold-blocking silicone
   • Shape into smooth curve
2. ​​Add Trim:​​
   • Inside corners: Use L-shape trim
   • Outside corners: Overlap trim
   • Floor edge: Angled baseboard trim
3. ​​Caulk Guide:​​​​Location​​​​Product​​Panel jointsPVC-specific siliconeTub/wall meetAnti-mold siliconePipe holesSpecial waterproof sealant

⚠️ ​​7 Common Bathroom Mistakes​​

1. ​​Forgetting space gaps​​ → Panels warp in steam
   • Fix: Leave gap at ceiling/floor

   • Fix: Wait 2 days after install
3. ​​Panels touching tub​​ → Water creeps up
   • Fix: Leave small space → fill with caulk
4. ​​Blocking air vents​​ → Mold grows
   • Fix: Cut around exhaust fans
5. ​​Skipping surface prep​​ → Panels fall
   • Fix: Rough up shiny surfaces
6. ​​No plumbing access​​ → Costly repairs
   • Fix: Add small removable panel
