Purpose:  Stock mats fade, warp, rip, or just stink.  Replace with Hydroturf or something similar for a different look and feel.  If you add footwells to a standup, you'll have to replace the turf.

Recommended for:  Anyone modding their hull/tray or anyone unhappy with their current mats.

Difficulty:  Easy when using a kit.  It takes a little more planning and attention to detail for custom jobs where you cut your own sheet.

Tools/Supplies:  

• eXacto blades (use very fresh razor blades if not eXacto...)
• Lint roller
• 1 can of contact cement - get Original not Gel
• Plenty of gel superglue
• 80grit sandpaper
• Orbital sander with 150-220 grit paper
• Masking tape
• Cheap paint/chip brushes
• Heat gun
• Rubber mallet
• Sharpie
• Straight edge
• Gloves
• Respirator
• Acetone for cleanup

Installation:  

1. Mask off your paint if you want to. 
2. Pre- or post-spray your footwells with paint that matches your turf so you won't really notice any spots that don't get covered.
3. Sand surfaces on your ski with 80-120grit
4. Hit the back of the turf and both sides of padding with an orbital sander and ~150-220grit. 
5. Clean up the klingons with a lint roller.
6. Apply padding and turf in sections - plan out your attack strategy.
7. Fit your padding how you like it - I recommend stacking thin padding on top of the thick stuff right about where the arches of your feet go to help keep them lined up and comfortable.
8. Apply contact cement to ski and to turf, let it dry, apply again, let it dry, don't goop too much on. 
9. Don't be afraid to leave some turf overhang in parts and cut as you go. 
10. If you peel up any turf because it's crooked, you might need to start all over, judgment call. 
11. Use a heat gun to soften up the turf just before and while you are stretching it over curves. 
12. Make relief cuts as you are stretching the turf into the footwells. If done right, you'll barely notice them afterwards.
13. Use fresh razors/xacto's and always cut at a 45deg angle. 
14. Beat it on with a rubber mallet asap. 
15. Superglue loose edges, gel style works good
16. Sand edges of turf with 80grit if you need to.
17. Don't waste your time cutting a stern eye if you are using thick padding. Instead just cut a slit in the turf at the rear run your tow loop under the padding

Turf flavors:

• Hydroturf @ www.hydroturf.com
  • Cut or molded - molded looks a little prettier but has limited colors
  • Self-adhesive or not - Self-adhesive is great for sit-down kits, but not for standups with footwells
  • Thick or thin padding - Personal preference but the thick stuff really is best for the trays of standups.  Padding is not required for sit-downs unless you want to get creative with your turf job.  I usually get self-adhesive on the thick padding.
  • B-stock - "scratch and dent" grey molded turf can be bought cheaper than the usual stuff
