Enjoy cumaru decking all year round on a covered porch. Just make sure it's protected from moisture.

2. Predrill into the seam where the boards will meet at a 45° angle.

3. Using a stainless steel trim head screw, secure the board to the joist.

4. Slide the next deck board into place, hiding the trim screw head.
