Woodworking projects require sanding to get a smooth, finished look. To create the perfect finish for your project, you may be wondering if you should sand between coats of stain.
Find out if it’s worth putting in the extra effort to sand between coats of stain. Let our pro woodworkers explain this matter in detail for a beautiful finish!
Sanding Between Coats Of Stain: Is it Recommended?
When staining wood, sanding between coats is only necessary before applying the first coat of stain. For most stains, you can simply add coats of the stain without any further preparation.
However, if using water-based stains, be sure to sand lightly with 300 fine grit sandpaper or higher after each application to improve smoothness and eliminate grain raising on the surface.
Pros
Eliminates Uneven Spots
Even with best efforts, water-based stains can cause uneven spots or raised grain sections on your project surface.
Light sanding between coats of stain will smooth these areas out, resulting in an even and polished look you’ll be proud to display!
Lightens The Stain
When a stain on wood turns out darker than desired, sanding between coats of stain can be your secret weapon to lighten it up.
This will not only reduce the darkness of the hue but also bring more definition and texture to its grain.
Cons
Removes the Majority Of Stains
Sanding between coats of stains removes the stain color coatings entirely, leading to more work and a poorer finish.
Store-bought pigments sit on top of the wood surface rather than being absorbed into it, so they are particularly at risk from sandpaper.
Alters Wood Grains
Too much sanding between coats of stain removes natural wood grain and blocks deeper absorption, resulting in a lighter second coat than desired.
To avoid this problem, we recommended minimizing or even bypassing sanding altogether.
Time-Consuming & Messy
Sanding between coats of stain is often messy and labor-intensive, so if it’s not creating a major advantage, we recommend skipping this step.
To make the best decision for your project, test sanding on a scrap piece of wood first.
How to Sand Between Stain Coatings
Tools You’ll Need
Belt Sander
A belt sander is a tool used to quickly remove wood and shape wood.
Random Orbit Sander
A random orbit sander is a tool used to sand wood and plastic surfaces.
Mouse Sander
Mouse Sander is a tool used for sanding in tight spots.
Drill Drum Sander
This tool is designed for sanding round holes or curved features.
Sanding Block
The Sanding Block is designed to sand between coats of small pieces of wood and knock off sharp edges.
Step 1
To create a beautiful finish on your project, choose sandpaper with a high grit number (220-240). This will ensure that any imperfections are gently smoothed out without damaging the stain. Never use steel wool [1].
Step 2
Make sure you have a sanding tool handy to make your project smooth as silk! If not, simply wrap the sandpaper around some scrap wood or even use just your hands. Either way, you’ll be one step closer to revealing an amazing finish.
Step 3
To bring out a beautiful wood finish, lightly sand the stain coat in one direction. Use multiple very light sandpaper to get rid of any rough patches, and inspect your progress by gently running your hand along the surface; it should be smooth and soft when done right!
Step 4
To remove dust from wood surfaces, start by vacuuming and finishing with a dry cloth. If you have an oil-based stain to deal with, dampen the cloth in mineral spirits for extra protection against any lingering particles.
Be sure not to use water on wooden objects – it can raise the wood grain, which will require sanding down again!
Can You Sand After Staining Wood? (Before Polyurethane): Here’s How!
Give your wood project a smooth surface and polished finish with these simple steps: Sand, coats of stain, then layer on the polyurethane for maximum protection!
Using a Sanding Tool
If you want your wood project to have a smoother finish, try using a sanding tool for even and effortless results. Just remember to keep at least 8 meters away from the surface to get that perfect result!
Using a Smooth Sandpaper
For a smooth, stained wood surface free from visible flaws, sand the wooden surface with 220-250 fine grit sandpaper. It’s important to go in the direction of the grain and make soft touches on both ends for the best result!
Using a Dry Cloth
Give dusty wood a makeover by dusting off the surface, wiping it with a dry rag, and, if using an oil stain, dipping the cloth in mineral spirits.
How to Sand Your Stained Wood Furniture
To remove old stain coats color, use 150-grit medium sandpaper until the bare wood appears. Then switch to fiber paper for an extra smooth finish. Make sure you always follow the wood grain when sanding between coats of stain.
How to Stain Your Wood Furniture Without Sanding
Try mineral paint for its durability and wood stain resistance, use bonding primer to skip the sandpaper on glossy surfaces like metal or glass, or liquid deglosser that works by applying it directly to create an instant chemical reaction with new wood stains.
Should You Sand All Types of Stains?
Oil-Based Stains
Oil-based stain is a popular choice for woodworking projects. Prepare the wood by lightly sanding between coats to help smooth out any grooves and scratches, then apply a thin layer of oil-based stain with a clean rag wiping off the excess stain as needed.
Water-Based Stain
To create a beautiful and smooth surface finish with water-based stain, it’s essential to sand between every coat – except for the last one.
A light grit of 220 or higher is best when using a dry cloth to wipe away any lingering dust from sanding between coats.
Gel Stains
With gel stain, you can kiss those tedious sanding sessions goodbye! This thick and paint-like product sits on the surface of your laminate cabinets or wood instead of penetrating its pores. So, no extra sanding between coats is needed after the first coat of gel stains.
Lacquer Stains
Lacquer stains are a great addition to your arsenal of wood staining solutions. No need to sand coatings in between.
For optimal results, take care when applying lacquer stain; if you spot any imperfections on the surface after application, simply wipe gently with a clean cloth until it’s smooth before adding that final touch.
Polyurethane Stains
Polyurethane stains, or simply varnish stains, give you two great options: oil-based stains and water-based stains.
Their fast drying time means that once each coat is applied, there’s no need to sand – plus any excess drip or mistakes can be wiped away straight away with varnish stains!
Metal-Complex Dye Stains
Enhance the color and durability of dense wood or outdoor finishes with metalized dye stains. These specialized tints use metals such as copper and chromium to create a stronger, more resilient finish that won’t fade easily.
With this stain, there’s no need for sanding between coats of stain, as it applies seamlessly straightaway!
Water-Soluble Dye Stains
Create the perfect shade of stain with this easy-to-use powder dye. Simply dissolve one ounce in a quart of water for drier tones, or add more powder for richer results.
And, because it’s water soluble, don’t forget to sand between coats of stain as you work your way toward an exquisite finish!
How Long To Wait for the Stain to Dry Before Sanding Again?
To tell if a water-based stain is dry enough to sand-stained wood, put your palm on the surface, and it should be neither wet nor cold.
You can also wait an hour up to four hours, depending on humidity levels in your area, or test by sanding off a small spot and seeing if the excess sanding dust turns whitish and sticks onto your paper.
Sanding Tips To Make Stain Look Great
Sand With Your Hand
The last step before staining is sanding wood, but don’t let it take too long! If you see scratches remaining after your first go-round, switch to a coarser grit and start again.
Don’t Oversand
Achieve an attractive look with smooth sanding and oil stains finish. But beware, rough scratching can lead to a less-than-ideal outcome if you choose to use stain coats. For the best results, opt for 220-grit sandpaper.
Sand in Diagonal Strokes
To achieve a smooth, even finish on your project surface, sand between coats diagonally with coarse-grit paper followed by fine sandpaper, finer and finest grits in alternating directions.
Use Waterproof Glue as Sealant
Protect outdoor furniture from rust and fungi with sealant! A waterproof epoxy solution is a perfect way to safeguard grainy, stained wood surfaces against erosive elements.
Clean Your Sanded Wood
You can blow off dust with a brush, air compressor, or vacuum. Then wipe down the sanded surface using either water or mineral spirits on a rag, and don’t forget to use a tack cloth for final cleansing before applying stains.
