As the sap and moisture dissipate from the material, it will have a natural tendency to shrink. Dry material should be spaced a full 1/4 inch apart to prevent damage to the boards as the material absorbs moisture. The gap will naturally close and widen throughout the year as the weather and seasons change.
Move the furniture off the porch. Remove old filler material, dirt or debris from the gaps between the boards with a scraper.
Also to know is, do cedar boards shrink?
According to Albany Fence Designs, while cedar wood will not shrink or warp in the presence of moisture, it will check. As a result, the outer layers shrink inwards, but crack when they bump into the denser, moisture-heavy inner layers.
Likewise, do pressure treated deck boards shrink? Over time, most treated lumber will shrink slightly across its width as it dries out. Take this small amount of shrinkage into account when laying decking or fence boards. After being outdoors for six to 12 months, treated lumber will develop cracks, called "checks," along the surface of each board.
Thereof, do deck boards shrink?
Regular pressure treated wood tends to be somewhat wet when it's new. That means, as it weathers in the sun and the heat, it will dry out some and shrink slightly. For this reason, I usually butt deck boards as tightly together as possible, so that they'll leave a slight gap when they do shrink.
Does cedar decking need to be sealed?
Cedar Decking Requires Maintenance In order to keep it in good condition, cedar decking does take a lot of maintenance. Even people who want a cedar deck that looks “rustic” will still need to seal the wood every year or so.
How long should cedar dry before building?
The traditional rule-of-thumb for air-drying lumber is to allow one year of drying time per inch of wood thickness; this adage obviously only takes a few of the aforementioned variables into account, but it's at least a rough starting point in understanding the time investment required in order to properly air-dryDoes Red Cedar need to be sealed?
Sealing Exterior Cedar Because of its rot-resistance and stability, cedar used for outdoor projects, such as furniture, fences, siding and play structures, lasts for years without any finish.

Keep your house at 40 percent humidity (not lower than 35 percent) if you have lots of wood in your house.

When the humidity is high, it's the exterior air that's humid.Can I leave my cedar deck untreated?

The goal is to have about an 1/8-inch gap (the diameter of an 8d nail) between boards after the decking has dried to its equilibrium moisture content. If the decking is installed wet, as is often the case for pressure treated material, it is best to install the boards tight, letting gaps form as the wood dries.Can you use 2x6 for deck boards?
2x6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Most decking is not strong enough to support longer spans than 16". Some builders reduce joist spacing to 12" on center to strengthen the deck frame or to increase maximum allowable joist spans.What gap do you leave between decking boards?
A gap of 10mm between deck boards and external walls of adjacent buildings is recommended for drainage. Board spacing depends on the width of the board but a guide is 3-4mm for 90mm boards and 5-6mm for 140mm boards. Note that if wet decking boards are laid, when they dry out the gaps between them will increase.How long do you have to wait to seal pressure treated wood?
