Your Essential Guide to Buying Grit Sandpaper for Wood
Choosing the right sandpaper makes a huge difference when you work with wood. Good sandpaper smooths wood nicely. Bad sandpaper can leave scratches and make your job much harder. This guide helps you pick the best grit sandpaper for your next woodworking project.
Key Features to Look For
When you shop for wood sandpaper, look closely at these important features:
1. Grit Number: The Smoothing Power
- What it means: The grit number tells you how coarse or fine the sandpaper is. A low number (like 40 or 60) means the paper is rough. A high number (like 220 or 320) means the paper is very smooth.
- When to use it: Use low grits for fast material removal, like shaping wood or removing old paint. Use high grits for final smoothing before applying stain or finish.
2. Mineral Type: What Does the Cutting?
The mineral is the actual abrasive material glued to the paper. Different minerals work best on different woods or tasks.
3. Backing Material: How Strong is the Paper?
The backing holds the grit onto the paper. It needs to be strong so it doesn’t tear easily while you sand.
Important Materials Used in Wood Sandpaper
The material of the abrasive grit and the paper backing are very important for how the sandpaper performs.
Abrasive Materials
- Aluminum Oxide: This is the most common and best choice for general woodworking. It cuts fast and lasts a long time on both hard and soft woods.
- Silicon Carbide: This grit is usually sharper and works very well for sanding finishes or very fine work. It is often used for wet sanding, though you might use it dry on wood too.
- Garnet: Garnet wears down faster than aluminum oxide, but it produces a very smooth finish, especially on softwoods.
Backing Materials
- Paper: Standard sandpaper uses a heavy paper backing. It is cheap but tears easily, especially if you sand curves.
- Cloth: Cloth backing is more flexible and much stronger. It lasts longer, especially when sanding edges or using orbital sanders.
Factors That Improve or Reduce Quality
Not all sandpaper is made the same, even if they have the same grit number.
Quality Boosters
- Closed Coat vs. Open Coat: Closed coat means the grit covers the entire surface. This removes material faster. Open coat has gaps between the grit, which helps prevent clogging when sanding softwoods or sticky materials. Open coat often lasts longer for general use.
- Adhesive Quality: Strong glue keeps the grit stuck to the paper. Poor glue means the grit falls off quickly, wasting your money.
Quality Reducers (Things to Avoid)
- Premature Loading: If the paper gums up with wood dust too fast, it stops cutting. This happens when the grit is too close together (closed coat) or the wood is very resinous.
- Paper Tearing: If the backing material is thin, it rips easily around corners or under heavy pressure.
User Experience and Use Cases
How you plan to use the sandpaper changes what you should buy.
Sanding Power Tools vs. Hand Sanding
- Power Sanders (Orbital or Belt): These tools use sandpaper very quickly. You need durable backing (like cloth or heavy paper) and a long-lasting grit, like aluminum oxide. You must buy the correct shape (e.g., round discs for orbital sanders).
- Hand Sanding: When sanding by hand, you can often use slightly lighter paper, as you control the pressure. Flexibility matters more here if you are sanding detailed moldings.
Project Stages
- Rough Shaping/Stripping: Start with low grits (40-80).
- General Smoothing: Use medium grits (100-150).
- Finishing: Finish with high grits (180-320) before staining or painting.
10 Frequently Asked Questions (FAQ) About Grit Sandpaper for Wood
Q: What is the best starting grit number for rough wood?
A: For wood that is very rough or has old paint, start with a grit between 60 and 80. This removes material quickly.
Q: When should I switch to a higher grit number?
A: You switch to a higher grit after the previous, lower grit has removed all the deep scratches. Never skip more than one grit number (e.g., don’t jump straight from 80 to 220).
Q: Does grit size affect how the wood stain looks?
A: Yes. If you sand too finely (using a very high grit like 400), the wood pores close up. The stain might not soak in evenly, leading to blotchy color.
Q: Is aluminum oxide always better than garnet for wood?
A: Aluminum oxide is tougher and lasts longer on most woods. Garnet is softer and breaks down faster, but it can give a slightly smoother initial cut on softer woods.
Q: What does ‘open coat’ sandpaper mean?
A: Open coat means there are small spaces between the abrasive grains. These gaps stop the paper from clogging up quickly with wood dust.
Q: How do I keep my sandpaper from loading up (clogging)?
A: Use open coat sandpaper when possible. Also, try wiping the wood surface occasionally with a tack cloth or a piece of scrap wood to clear dust.
Q: Can I use the same sandpaper for hardwood and softwood?
A: You can, but softwoods load up paper faster. You might need more open coat paper or need to change your paper more often when sanding pine or cedar.
Q: What grit should I use right before applying oil finish?
A: Aim for 220 grit. This smooths the wood enough for the finish to look good but keeps the pores open for the oil to penetrate well.
Q: What is the difference between sanding discs and sanding sheets?
A: Discs are round and attach to orbital sanders using Velcro or adhesive. Sheets are flat and you use them for hand sanding or on belt sanders.
Q: Is it okay to reuse sandpaper?
A: Yes, if it is not completely worn out. If the grit has fallen off, it is done. If it is just clogged, you can often clean it by brushing it or striking it against a clean scrap piece of wood.
