This 10-pound bucket of 18-40 grit walnut shells is the most balanced option for stripping paint from pine, oak, and other common restoration woods. The particles compress on impact — they shear paint layers without digging into the wood fibers — and the 10-pound quantity gives you enough media for multiple gun stock or furniture projects without running out mid-pass.

The Mohs hardness of 4.5 means it won’t etch glass or soft metals, but it handles paint removal on wood substrates extremely efficiently. Users running this in a blast cabinet report consistent stripping with minimal dust because the shells stay intact longer than harder media that shatters into fine powder.

Recyclability is strong: walnut shells can be cycled through a cabinet 5 to 8 times before they break down too small to strip effectively. That makes the per-project cost much lower than the initial price suggests, and the biodegradable material means disposal is simple.

Made in the USA, these #8 spec glass beads (70-100 grit) produce a smooth satin finish on wood after paint removal without leaving abrasive residue embedded in the surface. The round bead shape impacts at lower peak pressure than angular aluminum oxide, reducing the risk of warping thin wood panels or veneers.

Users highlight that this media works well with siphon-feed blast guns even on lower-CFM compressors. The glass beads are silica-free and inert, so they do not chemically react with the wood or leave contaminants that could affect stain adhesion later.

Volume-per-pound is the main trade-off: glass beads are denser than walnut shells, so 10 pounds looks smaller in the cabinet. For occasional wood stripping projects, the consistent finish and low etching risk make this a premium choice.

This 8-pound bag of fine 18-40 grit walnut shells is a straightforward entry point for wood paint stripping without the expense of larger bulk purchases. The organic media is silica-free and biodegradable, making cleanup easier than with mineral-based abrasives that leave sharp dust in the cabinet and on the shop floor.

Reviewers consistently note it removes paint and carbon buildup from intake valves and wood surfaces without damaging the substrate. The loose bulk density of about 40-50 lb/ft³ means this media carries well in a standard blast cabinet hopper without clogging the metering valve.

For projects on soft woods like cedar or poplar, the fine grit prevents the pitting that coarser media can cause. The 8-pound quantity suits smaller furniture pieces or sign work rather than full-house exteriors.

With a Mohs hardness of 9, this 100-grit aluminum oxide cuts paint layers faster than any organic media. The 14-pound bucket offers the best per-pound value among the harder media options, making it the choice for stripping paint from dense hardwoods like maple or teak where substrate marking is less of a concern.

Users report consistent cutting even after 10 hours of use in a blast cabinet. The media stays angular — it does not round off quickly like glass beads — so the stripping speed remains uniform through multiple recycles. The included sturdy plastic bucket prevents moisture contamination during storage.

On soft woods, 100-grit aluminum oxide can leave a visible etch if the blast pressure is not turned down. Keep the nozzle distance longer and PSI under 40 if you want to avoid grain damage on pine or fir.

If you are stripping paint from wood that has a metal component — like a cast-iron table base paired with a wood top — this 80-grit aluminum oxide handles both materials without requiring a media change. The Mohs 9 hardness cuts rust on steel and paint on wood with equal speed.

The manufacturer claims this media lasts ten times longer than silica sand per cycle. In practice, the angular brown fused aluminum oxide fractures into smaller cutting edges rather than rounding, so you get more usable media before it becomes too fine to strip effectively.

The 8-pound bucket is compact but the media is heavy, so the actual volume in the cabinet is low. For dedicated wood-only projects, walnut shells give better substrate protection, but for mixed-material restorations this is a strong contender.

These extra-fine glass beads (100-170 mesh) are the go-to media for cleaning paint residue from detailed wood carvings or moldings where you cannot tolerate any material removal from the original shape. The small bead size produces a peening action that dislodges paint without cutting the wood.

Users running this in a cabinet report consistent results on aluminum rims and car parts, and the same gentle action applies to wood. The beads leave a clean surface ready for primer without embedded grit that could telegraph through the new finish.

The main limitation is speed: extra-fine glass beads remove paint slowly compared to walnut shells or aluminum oxide. For a full furniture strip, this media requires more passes, but for delicate restoration work the safety margin is worth the extra time.

This 5-pound bag of 12/20 grit walnut shells is the most affordable entry into organic blasting media for small wood projects. The medium grit removes single layers of latex or oil-based paint effectively when used at low pressure (20-60 PSI) as recommended by the manufacturer.

The material is also marketed as a non-skid additive and pincushion filler, which hints at its gentle nature — it will not dull needles, so it certainly won’t gouge your wood. Users confirm the quality is consistent, though the 5-pound quantity is best suited for small workpieces like picture frames or trim pieces.

Some reviews note the media is dusty out of the bag. Pre-rinsing or running it through a sieve before loading the cabinet reduces airborne fines and improves flow through the blast gun.
