Many people recommend allowing the wood to dry first. Is it possible to sand wet wood? You have asked yourself this issue, particularly if you have been working on a few wood ventures and your wood supplies got caught in a rainstorm or spillage.
Let us find out the solution in this post to avoid misunderstandings. The wet board should not be sanded, particularly if used to make furniture. When boards are left outside to cure the climate, they must be hardened before sanding.
Why Do You Need Wet and Dry Sandpaper?
Woven sandpaper is suitable for engraved and twisted wood. If you have a mister water bottle, you can use dryer sandpaper. Keep the contact area moist with water and sand any fluid slop to avoid a large mess.
If you use a chain sander, the sander will be burnt. After the wood has been cured for a reasonable period, sand it again to remove the elevated grain.
Utilizing sand permeating oil in the last few coats on certain furniture like slab desks using wet and dry sandpaper and a specialist palm sander.
When wet, carving and twisted wood is simpler to work with. However, it becomes an issue with the vast majority of flat cards.
Sanding damp board is not suggested for making furniture. When boards are left outside to cure in the weather, they must first be dried before sanding.
What exactly is wet sanding?
Wet-sanding is a process used by furniture makers to provide a smooth and delicate finish to their work. Initially, the wood must be varnished and then dry-sanded properly.
It is also critical to select moist sandpaper and soak it in water before using it. Sanding wooden furniture in moderate rings should be done using damp sandpaper.
Sand the wood repeatedly or three times, adjusting the grit of the sandpaper each time.
What Supplies Will You Require?
The following items are required for dry and wet sanding:
- shellac or paint
- a sanding paintbrush or sling sandpaper (90, 105, 115, 125, and 150 grit for dry sanding)
- sanding sandpaper (210 grit to 2500 grit for wet-sanding)
Sanding removes a thin layer of wood or paints to smooth it out. It is critical to use a brush or cloth to apply paint or shellac before wet sanding.
Softwoods typically require three coats, whereas timber requires two to three coats. Before sanding, permit the shellac or paint to set overnight.
What exactly is dry sanding?
Dry sanding reduces the hardness of the wood to the stage where wet sanding is still most productive. You may use an automatic sander or hold the sandpaper in your hand.
Begin with 90 grit sandpaper, then go on to 110 grit, 125 grit, and 145 grit to 160 grit sandpaper to soften the wood.
Before actually wet sanding, dry sanding is performed. Eliminate the dust by using a motorized air compressor or a can of pressurized air to blast it away.
You may also use suction with a hose connected to a buster. Another approach is using a clean wet towel to wipe the dust away from the wood gently. Allow the wood to cure before proceeding.
How Do You Sand Wet?
Wet sanding requires a different type of sandpaper than dry sanding. Wet sandpaper is designed to stand up while wet, and it has a finer grit for a smoother texture.
The minimum grit used is 210, while the maximum grit utilized is 2500. Sanding hydrogels, which adhere to the surface much smoother than sandpaper, can also be utilized.
Immerse the fine-grit sandpaper in water for at least one day, preferably overnight. As a result, the sandpaper will absorb as much water as feasible. If you hurry, soak the sandpaper for at least 10 minutes while you get everything ready.
Before sanding, lubricate the fine-grit sandpaper. Soaking it in water is beneficial; sometimes, immersing the sandpaper in grease is essential while sanding.
Heterogeneous spirits, and a mixture of water and soap, are efficient lubricants. Ensure the sandpaper does not dry out as you work and moisten it every few hours as a basic guideline.
Thread the sandpaper around a loofah or wood board, leaving a few centimeters of sandpaper interface with the wood. Simply holding the sandpaper in your palm will not cover the same amount of ground.
Sand, the surface of the wood in circular movements, exerting light pressure while keeping the fine-grain sandpaper on the wood. It is not required to adhere to the wood’s grain exactly. Keep your hand moving circularly along the wood.
Begin with a border and work your way down one edge of the board to the other, working down the wood a little and sanding halfway across toward the corner.
Repeat this sequence while sanding from sideways. After sanding, polish the surface wood and add a sealant if needed.
The wet board should not be sanded, particularly if used to make furniture. When boards are left outside to cure in the weather, they must be dried before sanding; I hope you found this topic interesting!
