How to Install Cumaru Decking with Wood Plugs
Cumaru is a gorgeous wood, so why mar that natural beauty with unsightly screw holes? Using cumaru wood plugs with S4S E4E (surfaced 4 edges / eased 4 sides) can hide these holes and make your deck surface look flawless. Follow these illustrated instructions to bring out the real beauty of your deck:
1. Countersink 3/8" holes into face of deck boards.
2. Pre drill 1/8" pilot holes completely through the deck boards.
3. Screw the deck boards down with stainless steel screws.
4. Glue cumaru plugs into the holes with waterproof glue.
5. Knock off plug tops with a chisel.
6. Sand smooth with 80 grit sandpaper (a round orbit sander works great).
