A lot of folks make the mistake of sanding to either too fine of a grit or not fine enough before applying stain. Too fine and the wood won’t be able to accept the stain. Too rough and the wood will be very dark almost to the point of being black.

Is sanding necessary before staining?
Sand Thoroughly
The best way to stain wood is to prepare the wood surface by sanding it with a sanding block or orbital sander. Sandpaper with a lower grit number will make wood rougher, allowing more stain to absorb and creating a darker color. Start with 120-grit sandpaper on refinished pieces.
Can you stain unfinished wood without sanding?
Most unfinished pieces need additional fine sanding before finishing to avoid surface fuzz or roughness that will show when the stain is applied.
Can I stain over stain without sanding?
Can you restain wood without sanding? While some light sanding may be advised for almost all stain projects, it is possible to avoid heavy sanding and stripping of existing stain. Using a gel stain means that you can avoid the heavy sanding and stripping usually required by traditional staining projects.
What happens if you don’t prep wood before staining?
Without diligent and effective preparation, your refinished product is up against obstacles like dust, wax, existing stain or irregularities in the wood surface. Fight as you will – if you don’t spend a bit of time making sure the wood surface is clean, your end result isn’t going to live up to expectations.
How much do you have to sand wood before staining?
On most raw woods, start sanding in the direction of the grain using a #120-150 grit paper before staining and work up to #220 grit paper. Soft woods such as pine and alder: start with #120 and finish with no finer than #220 (for water base stains) and 180 grit for oil base stains.
What happens if I don’t sand wood before painting?
It will look blotchy and rough, but it’s doing its job locking in the stain and creating a rough surface so the paint will adhere to it. What is this? DON’T SCRATCH AT THE BONDING PRIMER TO TEST ADHESION!
What happens if you stain Unsanded wood?
Likewise, when stained, the coloring along the grain of an unsanded board will appear mottled instead of crisp and evenly colored. To properly prep bare wood, first sand with 120-grit sandpaper to open the grain of the wood.
Should you sand unfinished wood?
Do NOT start sanding with very fine sandpaper on unfinished wood. Prepare the surface by using medium sand paper first, and then proceed to finer grades. Water based finishes need a smoother surface than oil based finishes, but do not over sand or you may seal the wood so much that it will not take a finish.
What happens if you sand after staining wood?
Sanding to at least 180 grit can clog the pores of the wood, and reduce stain absorption, leading to a less-blotchy appearance when staining softwoods.
Will 2 coats of stain make it darker?
Apply a second coat of stain after the first has dried fully. This will usually produce a darker coloring, but it adds a step to the process and slows production. Substitute a glaze or gel stain for the liquid stain.
Can I stain wood that is already stained?
To go from a dark shade to a lighter shade, you must strip and remove the dark shade first. When it comes to furniture and wood, staining over stain works exactly the same way!
What happens if you stain over polyurethane?
No, a standard oil stain won’t work on top of a polyurethane coat. Instead, the stain will just wipe off and leave no color behind after applying it. Standard oil-based wood stain works by seeping into the wood, but the coat of poly won’t allow penetration.
Can you stain right after sanding?
After sanding, power-wash the deck and allow it to dry for at least 24 hours before staining. Sanding exposes porous wood that’s ready to soak up the stain, but this isn’t possible if the wood is full of water.
How do you smooth wood after staining?
After the first “sealer” coat has dried, sand it smooth using very fine sandpaper. Not doing this is probably the single most common cause of finishes not feeling smooth after all coats have been applied. The most important thing you can do to achieve smooth results is to sand the first coat smooth.
Do you sand after water popping?
Once the surface is water popped, there is no need for additional sanding. If you were to sand the raised grain smooth again, you defeat the intent of the water popping.
How do you know if you sanded enough?
The best way to know when you’re done sanding is to scribble a light pencil line across your wood before you start. Once the line is gone, move up to the next grit. Repeat up to the highest grit sandpaper, then wet your wood with mineral spirits to confirm there are no remaining marks.
Why is my stain not penetrating the wood?
There are a couple of reasons wood won’t absorb stain. These include staining sealed wood, sanding too finely, and working with tight-grained woods that don’t take stain. There are specific solutions to each problem, but generally applying a sealer and a stain that sits on top of the wood is a simple solution.
Can you stain after sanding with 60 grit?
Even fresh lumber can have a “mill glaze” on it which will prevent proper staining. No matter what the condition of the wood it will likely need sanding first. Start with a 60-grit sandpaper to strip everything bare and then work up to an 80-grit paper and eventually finish with a 120-grit paper.
Do you always have to sand before painting?
Do you have to sand furniture before painting? Sanding isn’t always necessary. If you are painting over the same type of paint, sanding isn’t necessary if the furniture is in good condition (not peeling or chipping). However, be sure to wipe any dust or debris from the furniture before painting.
Can you stain over paint?
While you can stain over paint, realize that you are creating a unique look, not an authentic stained wood-grain look. For that, first strip off all of the paint, then apply the stain. Paint with greater gloss means that the surface is less porous. The stain will more easily slide off, resulting in a lighter color.
