Does the crown go up or down on deck boards? This is a common question among homeowners and contractors when it comes to installing or maintaining wooden decks. Understanding the direction of the crown in deck boards is crucial for ensuring the longevity and stability of your deck. In this article, we will explore the concept of crown, its importance, and how to determine whether it should go up or down on deck boards.
Deck boards are typically made from wood, such as cedar, redwood, or pressure-treated lumber. Wood is a natural material that expands and contracts with changes in moisture content and temperature. This expansion and contraction can cause the deck boards to warp, cup, or twist, leading to an uneven surface. The crown of a deck board refers to the direction in which it naturally curves or warps.
There are two types of crowns: concave and convex. A concave crown is when the center of the board is lower than the edges, while a convex crown is when the center of the board is higher than the edges. When installing deck boards, it is essential to consider the direction of the crown to ensure proper alignment and stability.
Does the crown go up or down on deck boards? The general rule is that the crown should go up on deck boards. This means that the edges of the board should be slightly higher than the center. This upward crown allows the board to expand in the summer months when temperatures rise and moisture content increases. If the crown goes down, the board will be more prone to cupping and warping, as it will not have enough room to expand. This can lead to an uneven surface and potentially damage the deck structure.
When installing deck boards, it is important to follow these steps to ensure the correct direction of the crown:
1. Inspect the deck boards for any warping, cupping, or twisting before installation.
2. Lay out the deck boards on the ground to determine the direction of the crown.
3. Start with the longest board on the longest side of the deck, aligning the edges of the board with the house or railing.
4. Place the next board next to the first one, ensuring that the edges are even and the crown is going up.
5. Continue installing the deck boards, checking for alignment and proper spacing between each board.
6. Use a level to ensure that the deck surface is even and that the crown is going up on each board.
By following these steps and understanding the importance of the crown direction, you can ensure that your deck remains stable, level, and aesthetically pleasing for years to come. So, next time you wonder, “Does the crown go up or down on deck boards?” remember that the answer is up, and it’s a critical factor in maintaining the integrity of your deck.
