GoBoard Washers

INSTALLATION

1. Position GoBoard. Use shims or spacers to ensure 1 /8“ gaps.
2. Place first GoBoard Washer approximately 12” from edge (push washer into GoBoard surface). 
3. Install the provided Hi-Lo or Self-drilling fastener.
4. Install remaining washers spaced 12” apart in the interior area (field) of board. To ensure a waterproof installation, GoBoard Washers should be only installed around board perimeters AFTER GoBoard Pro Sealant has been applied.
5. Position next board; use spacers to ensure 1 /8 “gaps.
6. Repeat steps 2 thru 4 to install GoBoard Washers.
7. Install additional boards until wall is covered with GoBoard.
8. Fill 1 /8“gaps with GoBoard Pro Sealant or equivalent.
9. Repeat steps 2 thru 4 to install washers over joints.
10. Using a putty knife, spread excess sealant 1” on either side of joint joints. Apply more sealant as needed.
11. Apply sealant over each washer.
12. Using a putty knife, spread sealant to completely cover washer with sealant. Apply more sealant as needed.

Cover adjacent walls with GoBoard repeating steps 1 thru 12. Once all boards are installed, begin tiling when GoBoard Pro Sealant has formed a suitable skin layer, which is usually 30 to 60 minutes depending on ambient conditions. In dryer climates or when installing at colder temperatures, GoBoard Pro Sealant will take longer to skin over.

FASTENING TIPS

• Use the included T-25 Torx bit for GoBoard Fasteners with any variable speed corded or cordless screw gun or drill.
• If using backer board screws from another manufacturer, use the appropriate bit.
• If applicable, when fastening the panels without GoBoard Washers, make sure to adjust clutch setting such that fasteners are seated flush and not overdriven through top surface of board.
• For waterproof installations, make sure to seal each fastener penetration, with GoBoard Sealant, GoBoard Pro Sealant, or approved alternative - extending the sealant approximately 1-in in diameter around the perimeter of each GoBoard Washer.
