Tips & Warnings

• Be sure to imbed your pier blocks into the ground so that there is no risk of the spa deck sagging later on.
• Make sure when you are attaching your boards to the floor joist that you use screws and not nails. Nails will work themselves out of the boards over time.
• Make sure you check the level of the pier blocks and edge band before installing your deck boards.
• Also check that the deck boards are not warped.
• It is very important to use pressure-treated wood when an item built is made for outdoors.
• A good sealer should be reapplied at least once a year for proper protection.
