Buying a variety pack then still needing 100 grit

A variety pack that skips 100 grit is not necessarily a bad purchase, but it may be the wrong pack for your project. Before buying another assortment, check the grit sequence you actually need, the sanding format that fits your tool or hand-sanding method, and whether a small pack of 100-grit paper costs less than unused sheets in a larger assortment.

Why variety packs often leave out 100 grit

Variety packs are usually designed to cover broad sanding stages rather than every grit in a continuous progression. A pack may include coarse, medium, and fine sheets while skipping useful intermediate grits such as 100.

Common reasons include:

• The manufacturer is trying to limit the number of sheets in the package.
• The assortment is built around popular starting and finishing grits.
• The pack is intended for light finishing rather than material removal.
• The grits are distributed across a range instead of supplied in consecutive steps.
• Different pack sizes are aimed at different tools or materials.

The important point is that “assorted grits” does not mean “every grit you might need.” Always read the included-grit list before buying.

When 100 grit is worth buying separately

100 grit is a practical middle-ground option for many wood and refinishing jobs. It can remove visible scratches, smooth rough surfaces, and prepare wood after a coarser pass without being as aggressive as a very coarse abrasive.

Buying 100 grit separately makes sense when:

• Your project instructions specifically call for it.
• You need to remove material faster than fine paper can manage.
• A coarser grit leaves scratches that need an intermediate step before finishing.
• You are sanding bare wood between rough shaping and fine smoothing.
• You only need one missing grit and would otherwise leave most of a second variety pack unused.

Do not assume 100 grit is always the correct choice. The best grit depends on the existing finish, the condition of the surface, the wood species, and whether you are sanding by hand or with a power sander.

A simple way to choose your grit range

Start with the surface condition rather than the number printed on the package.

For rough wood or significant defects

Begin with a coarser grit only if you need to remove substantial material, level uneven areas, or strip a failing finish. Coarse paper cuts quickly but can leave deep scratches that require additional sanding.

For general smoothing

A medium grit such as 100 may be useful after a coarse pass or when the surface needs more correction than fine paper can provide. Use light pressure and inspect the surface often so you do not create unnecessary scratches.

For final preparation

Move to a finer grit when the surface is already reasonably smooth and you are preparing for paint, stain, or a clear finish. The required finishing grit varies by coating and manufacturer instructions, so avoid sanding finer than necessary if the next coating needs some surface texture for adhesion.

A useful rule is to change grits when the current paper stops making progress, not simply because a preset variety-pack sequence says to do so. Remove the scratches from the previous grit before moving finer.

Compare the real cost, not just the pack price

A variety pack may have a lower price per package but a higher cost per useful sheet. Compare these details:

• How many sheets or discs are included in each grit?
• Is 100 grit included at all?
• Are the pieces the correct size for your sander?
• Will the abrasive attach to your tool’s hook-and-loop or clamp system?
• Are you buying several grits you will not use?
• Is the paper intended for wood, paint, metal, or multiple materials?
• Will you need extra sheets because the abrasive loads quickly?

If you need only 100 grit, a single-grit pack is often the more economical choice even if its package price is higher than a small assortment. If you are starting a larger project and need several stages, a variety pack can still make sense—but only when its grit list and format match the job.

Choose the format before the grit

The grit number does not tell you whether the abrasive will fit your equipment.

Sheets

Sheets work for hand sanding, sanding blocks, and some sheet-fed finishing sanders. Check the sheet dimensions and whether the paper is easy to cut or fold without exposing an abrasive edge that could damage the surface.

Sanding discs

Discs must match the sander’s diameter, attachment system, and dust-hole layout where applicable. A 100-grit disc that does not fit your tool is not a bargain.

Sanding sponges

Sanding sponges can conform to edges and contoured surfaces. They may be more convenient for detail work, but they are not interchangeable with flat sheets or machine discs.

Precut or specialty formats

Some tools require narrow belts, triangular detail-sanding sheets, or other shaped abrasives. Confirm the tool’s consumable size and attachment method before comparing grit packs.

How many 100-grit sheets should you buy?

Buy enough for the surface area and sanding method, but avoid assuming that one sheet will last through an entire project. Paper wears, clogs, tears, and loses cutting ability. Paint and resin can load the abrasive especially quickly.

A small pack is reasonable when:

• You are correcting a limited area.
• You are testing how the surface responds.
• 100 grit is only one step in a small repair.

A larger quantity is more practical when:

• You are sanding multiple furniture panels or doors.
• You are removing a coating from a broad surface.
• You are using a power sander.
• You want matching replacement paper available during the project.

For machine sanding, follow the sander manufacturer’s instructions for compatible abrasives and dust collection. Replace paper when it stops cutting rather than pressing harder; extra pressure can reduce sanding efficiency and damage the workpiece or tool.

When the variety pack is still the better buy

Keep or choose the variety pack when it includes grits you will use in a planned sequence and the formats fit your equipment. It can be useful for a project that involves rough correction, intermediate smoothing, and final preparation.

It is less attractive when:

• The pack skips the one grit your project requires.
• It contains too few pieces of the grits you use most.
• The sheets or discs are the wrong size.
• The assortment mixes materials or formats you do not need.
• You are paying for fine grits when the project mainly requires surface removal.

If you already bought the pack, use its grits where they fit the job and add 100 grit separately. Do not force an overly coarse-to-fine jump if it leaves scratches that take longer to remove than the extra intermediate step would have.

What to check before your next purchase

Use this quick checklist:

1. Identify whether you are removing material, smoothing scratches, or preparing for a coating.
2. Write down the grits you expect to use, including 100 grit if it is part of the sequence.
3. Confirm whether you need sheets, discs, sponges, belts, or another format.
4. Match the abrasive dimensions and attachment method to your tool.
5. Compare the quantity of each grit, not just the total number of pieces.
6. Check that the abrasive is intended for your material and finish.
7. Buy a single-grit pack when the missing grit is the only item you need.

If a variety pack repeatedly leaves you buying individual grits afterward, a project-specific assortment—or separate packs of the grits you use most—will usually be easier to budget and less wasteful.
