A blasting machine for wood can be used to remove old paints, deteriorated wood stains, adhering dirt and residues from shutters, window frames, beams, doors, furniture and craft artefacts. However, the machine must be chosen according to the wood species, coating thickness, geometry and required aesthetic result. For small localised jobs, an electric blasting machine may be sufficient; for shutters and furniture, a compact pneumatic machine may be suitable, while professional work requires an adjustable low-pressure system. Beams, tongue-and-groove panelling and batches of windows and doors instead require greater autonomy and working continuity.
Why use blasting on wood
Blasting can reach pores, joints, slats, mouldings, edges and irregularities that are difficult to treat uniformly with sanders and manual tools.
It can be used to:
- ✓ Remove old paints
- ✓ Remove deteriorated wood stains
- ✓ Clean blackened surfaces
- ✓ Reduce surface residues
- ✓ Restore the grain
- ✓ Obtain an aged effect
- ✓ Treat surfaces before a new finish
- ✓ Work on complex geometries
- ✓ Clean wooden parts combined with metal hardware
Blasting does not automatically replace sanding in every phase. After treatment, it may be necessary to:
- ✓ Even out the fibres
- ✓ Finish some areas manually
- ✓ Remove residues
- ✓ Check moisture
- ✓ Apply consolidating products
- ✓ Carry out light final sanding
- ✓ Prepare the painting or wood-staining cycle
Wood does not all react in the same way
The correct configuration depends on the structure of the material. The following must be assessed: wood species, hardness, grain direction, density, moisture, presence of knots, state of conservation, thickness, presence of glued joints, any veneer, existing finish, historical or craft value. Soft wood can be eroded quickly in less dense areas. Hard wood can tolerate a more incisive treatment, but can still lose details, edges or surface finishes.
Softwoods
Spruce, pine and other relatively soft species have areas with different densities. A jet that is too intense can remove the softer fibres more quickly and create: very pronounced grain, irregular surface, excessive brushed effect, small grooves, loss of edges and greater absorption of the subsequent finish. The effect may be desired in some decorative treatments, but may represent a defect when stripping a window or door frame.
Hardwoods
Oak, chestnut, beech and other more compact species may require greater removal capacity, especially when covered with resistant paints. Greater hardness does not eliminate the risk of modifying texture, opening the pore excessively, wearing details, creating colour differences or increasing roughness.
Ancient wood
Ancient wood may present dehydrated fibres, biological attack, friable parts, repairs, old consolidants, fillers, nails, weakened joints, several layers of paint and significant differences from one area to another. Processing must start from a conservative sample. An apparently robust area does not necessarily represent the entire artefact.
Veneers and thin panels
On veneers, thin plywood, MDF and laminated panels, blasting must be assessed with particular caution. The jet can go through the surface layer, reveal the underlying support, damage edges, open glued joints, lift fibres or coatings and create unrecoverable depressions. When it is not possible to carry out a representative test, an alternative technology may be preferable.
Main applications of wood blasting
Shutters and window frames
Shutters and windows and doors have a complex geometry made up of slats, rebates, frames, edges, joints, hardware and areas that are difficult to reach. Blasting makes it possible to work on areas that would require a great deal of time with manual sanding alone. However, the jet must be adjusted to avoid rounding edges, eroding slats, opening joints, altering mouldings and excessively wearing the most exposed areas. For professional work, the main solution is normally an adjustable blasting machine such as SABIX 8. TROLLY can be assessed for a limited quantity of shutters or less continuous jobs.
Beams and roof beams
Blasting beams can be useful for removing old paints, eliminating blackening, reducing residues, restoring the natural appearance, highlighting the grain, treating irregular surfaces and reaching cracks and splits. Beams may show significant differences between sound wood, sapwood, heartwood, knots, eroded parts, areas attacked by insects, repairs, mortar or plaster residues. On extensive surfaces, tank capacity and operating continuity become relevant. In these cases, SABIX 28 can be assessed, as it offers greater autonomy while maintaining a transportable configuration.
Furniture and furnishings
Blasting furniture must be assessed according to wood thickness, construction system, presence of veneer, carvings, glued joints, decorations, hardware, historical value and aesthetic result. On rustic solid-wood furniture, it may be possible to use a controlled jet to remove old finishes or create a material effect. On veneered, inlaid, gilded or decorated furniture, open blasting may be excessive or unsuitable. For moderate surfaces and robust furniture, TROLLY can be assessed, always proceeding through a preliminary sample.
Doors and large doors
Solid-wood doors can be treated to remove paints, wood stains, dirt, residues and degraded finishes. Attention must be paid to panels, mouldings, edges, joints, repaired parts, differences in wood species, hardware and glass. A large flat surface allows higher productivity, but the operator must reduce intensity when approaching reliefs, frames and edges.
Tongue-and-groove panelling and cladding
Tongue-and-groove panelling can cover extensive surfaces and have repeated joints. Blasting can reach grooves, but it is necessary to maintain constant travel speed, uniform distance, regular overlap, stable abrasive dosage and direction consistent with the grain. A machine that is too small may require many refills, while an excessive configuration can quickly erode the substrate. For this type of work, SABIX 28 may be more consistent than compact systems, provided the compressor and jet are correctly sized.
Small localised jobs
For touch-ups, repairs, hard-to-reach areas or work without a compressor, BLSTR sander can be assessed. However, it must not be confused with a machine intended for continuous stripping of beams, entire tongue-and-groove surfaces or large batches of windows and doors.
What result is required
The jet and type of abrasive vary according to the processing set for the wood:
- Paint stripping: Paint removal depends on composition, thickness, number of layers, adhesion, elasticity, penetration into pores and wood hardness. A highly adherent paint may require stronger action than a finish that is already flaking. It is not always correct to seek total removal in a single pass. Progressive treatment reduces the risk of eroding the substrate in areas where the paint detaches first.
- Surface cleaning: Cleaning requires lower intensity than paint stripping. The aim may be to remove dirt, consolidated dust, blackening, surface residues and non-adherent finish parts. In this case, it is often preferable to work with fine abrasive, reduced dosage and quick passes.
- Aged effect: Blasting can wear softer fibres more and leave harder fibres in relief. This effect can be intentionally used on beams, panels, cladding, rustic furniture and decorative elements. The result must be defined with a sample, because the effect varies greatly between wood species and cuts.
- Treatment before a new finish: After removing paint or wood stain, the surface must be checked before applying primer, wood stain, oil, wax, paint or protective treatment. Excessive roughness can increase absorption and make it difficult to obtain an even finish. Light sanding may therefore be necessary afterwards.
Wood-blasting technologies
Electric blasting machine without compressor
A portable electric blasting machine can be useful when the job is localised, a compressor is not available, work must be carried out at height, space is limited, a machine must be ready quickly and the surface is not extensive. The main advantage is logistical. There is no need to transport a compressor, pressure vessel and pneumatic hoses. The limitation concerns productivity and autonomy: it is not the primary solution for continuous work on large quantities of shutters, beams or cladding.
Compact pneumatic blasting machine
A compact open-blasting machine offers greater continuity than an electric tool, nozzle choice, pressure adjustment, the possibility of changing abrasive and better adaptability to moderate surfaces. However, it requires a correctly sized compressor and proper dust and abrasive management.
Professional low-pressure blasting machine
For windows and doors, shutters, ancient wood and sensitive surfaces, it is important to be able to adjust pressure, abrasive quantity, particle size and jet intensity. SABIX 8 is designed for controlled work, low-pressure blasting and operations on sensitive materials.
Blasting machine with greater autonomy
When surface area, number of artefacts, frequency of use, working hours and quantity of paint to be removed increase, it becomes important to reduce pauses for abrasive loading. SABIX 28 has a 28-litre tank and can be assessed for longer jobs, including applications on windows and doors, beams and furniture.
Blasting with dampened abrasive
Dampening can help reduce dust lifting, but on wood it must be assessed carefully. The following must be considered: water absorption, swelling risk, glued joints, connections, hardware, residual moisture, drying times and the subsequent finishing cycle. The Acquablast kit available for SABIX 8 and SABIX 28 must not be used automatically on every wooden surface. The choice depends on the artefact, the quantity of water and the possibility of obtaining correct drying.
How to choose the abrasive for wood
There is no abrasive suitable for every wood species and every coating. The choice must consider: wood hardness, fibre condition, paint to be removed, desired effect, particle size, grain shape, friability, amount of dust and compatibility with the machine.
- Vegetable granulates: Plant-based granulates can be assessed when a relatively progressive action is required. They may be suitable for ancient wood, furniture, delicate surfaces, removal of light finishes and controlled cleaning. Their lower hardness does not eliminate the need for a sample.
- Bicarbonate: Bicarbonate can be considered for some cleaning and light-removal operations. It is relatively friable and can produce a significant amount of dust. Complete removal of residues before the new finish must also be checked.
- Fine mineral abrasives: Fine mineral abrasives can be used on wood by correctly choosing particle size, pressure, distance, quantity delivered and travel speed. They are suitable when greater removal capacity is required than with softer granulates. On delicate or soft woods, it is necessary to start from a low-aggression sample.
Abrasives to avoid: Generic sands must not be used: damp, unclassified, irregular in particle size, undocumented or potentially containing free crystalline silica. An unsuitable abrasive can produce clogging, wear, uncontrolled dust, non-repeatable results and risks for the operator.
Pressure, nozzle and compressor
Pressure is not the only parameter. Lowering pressure is not sufficient to protect wood. The result also depends on abrasive hardness, particle size, nozzle diameter, distance, angle, dosage, travel speed and exposure time. A hard abrasive used very close to the surface can erode wood even with relatively low pressure.
Nozzle diameter and distances: A small nozzle concentrates the jet more, facilitates localised areas, reduces the treated area and can increase the risk of point etching. A larger nozzle covers a wider strip, increases air demand, can improve productivity and requires greater attention on edges. A short distance concentrates energy. As distance increases, the jet spreads, point intensity decreases, the affected area increases and control on delicate surfaces can improve. A perpendicular jet tends to etch more. A more grazing angle can help lift some paints, but can accentuate the grain by following softer fibres.
Air compressor: The compressor must be sized according to the model, nozzle, pressure, required airflow, hose length and continuity of use. An undersized compressor causes pressure drops, an intermittent jet, unstable dosage, longer times and an irregular finish. It is not sufficient to assess the declared maximum pressure. What matters is the airflow actually available during the work cycle.
Dust and safety
Wood blasting can disperse wood dust, abrasive, old paints, wood stains, residues, fibres and contaminants present on the surface. Prevention measures must consider: area delimitation, ventilation, extraction or capture, periodic removal of deposits, respiratory protection, eye and face protection, operator hearing protection, gloves, suitable clothing, control of ignition sources, verification of old paints and separate management of residues. Wood dust can represent a respiratory risk and, under certain conditions, a fire or explosion hazard. Old paints, wood stains and protective treatments must not automatically be considered harmless. Before treating very old artefacts, it is advisable to identify, as far as possible, the nature of the coating.

Frequent mistakes
Mapping unsuitable operating behaviours protects the integrity of the wooden artefact:
- Using excessive pressure: Excessive pressure can erode the fibres before the paint has been stripped uniformly.
- Using the same abrasive on every wood species: An abrasive suitable for oak may be too incisive on spruce, pine or degraded wood.
- Insisting on areas still covered with paint: When paint penetrates the pores, insisting with the jet can wear the wood without achieving complete removal.
- Not checking edges: Edges, borders and frames are worn more quickly than flat surfaces.
- Treating veneer like solid wood: A thin layer can be penetrated in a few moments.
- Choosing a machine that is too small or too large: A compact machine may be suitable for one shutter, but become unproductive for dozens of windows and doors or large beams. A configuration oriented towards intensive work can be difficult to control on slats, furniture and details.
- Not drying compressed air correctly: Condensate and humidity can agglomerate the abrasive and make the jet discontinuous.
- Using water without assessing the artefact: Moisture can penetrate the fibres, open glued joints or delay application of the subsequent finish.
- Not managing dust: The dispersion of wood dust and old paints can make the operation hazardous and contaminate the working environment.
FAQ on blasting machines for wood
Which FEVI blasting machine is most suitable for shutters?
For professional work on shutters and windows and doors, SABIX 8 is the main proposal because it allows accurate adjustment of pressure and abrasive. For limited quantities, TROLLY can be assessed, while SABIX 28 is more suitable when the number of windows and doors requires greater autonomy. The choice must always be confirmed by a sample on the real wood, paint and geometry.
What is the difference between SABIX 8 and SABIX 28 on wood?
Both are adjustable professional blasting machines that can be used on shutters, windows and doors, beams and furnishings. SABIX 8 prioritises compactness, handling and control in small and medium-scale work. SABIX 28 has a larger tank and allows longer work between refills. The choice depends mainly on surface area, frequency and productivity.
Can wood be blasted without a compressor?
Yes, for small jobs, BLSTR sander® can be used, as it works with electrical power and does not require compressed air. It is suitable for localised areas, maintenance and surface blasting. However, it does not offer the same operating capacity and flexibility as a pneumatic blasting machine on complete shutters, beams or large panels. Before use, the abrasive and result must be checked on a sample.
Can blasting damage wood?
It can damage it if abrasive, pressure, nozzle, distance and speed are not correct. The main risks are fibre erosion, loss of edges, increased roughness and alteration of the grain. Soft woods and degraded parts are particularly sensitive. Blasting must start with a conservative configuration, gradually increasing intensity. Even the most robust surface must undergo a preliminary test.
Which abrasive should be used for shutters?
The choice depends on the wood species and paint. Plant-based granulates, bicarbonate or fine mineral abrasives can be assessed, but none is automatically suitable for every shutter. Resistant paint on hard wood may require a more incisive material than a light finish on soft wood. The sample must check removal, roughness, fibre erosion and quantity of dust.
Which blasting machine should be used for beams?
For localised work or a few beams, SABIX 8 can be assessed. When surfaces are extensive or work is continuous, SABIX 28 offers greater autonomy. The configuration must consider wood species, blackening, paints, presence of degraded areas and accessibility. On ancient beams, an unintended eroded effect must be avoided.
Is TROLLY suitable for furniture?
TROLLY can be assessed on robust solid-wood furniture and moderate-sized surfaces. It must not be used automatically on veneers, inlays, gilding or very thin parts. Pressure, abrasive and distance must be checked with a sample. For furniture of historical value or with complex decorations, specialist assessment is necessary.
Is it possible to use water during wood blasting?
It is possible in some applications, but it is not always advisable. Water can reduce dust lifting, but it can also penetrate fibres, cause swelling, interfere with glued joints and extend the time before the new finish. On SABIX 8 and SABIX 28, the Acquablast kit can be assessed, but the quantity of water and compatibility of the artefact must be verified before work.
Which compressor is required for blasting wood?
The compressor must be sized according to nozzle consumption at the actual working pressure. It is not sufficient to consider maximum pressure or tank volume. The blasting-machine model, nozzle diameter, hose length, required continuity and abrasive must be known. An insufficient compressor produces an intermittent jet and makes it difficult to obtain an even finish.
Does blasting completely replace sanding?
Not always. Blasting is effective for removing paints and reaching irregular areas, but it can leave raised fibres or a marked texture. Before applying a new finish, light sanding may be required to even out the substrate. The cycle depends on the required aesthetic result: a rustic effect can accept a more textured surface, while a painted window or door normally requires greater regularity.
Let’s identify the correct blasting machine for your wood project
The choice between BLSTR sander®, TROLLY, SABIX 8 and SABIX 28 depends on the artefact, finish and required productivity. To assess the configuration correctly, it is useful to tell us the wood species; type of artefact; dimensions; paint or treatment to be removed; state of conservation; presence of carvings or veneers; number of pieces; frequency of use; required aesthetic result; possibility of using water; working environment; and available compressor.
FEVI can verify machine, abrasive, particle size, nozzle, pressure and airflow together with the user, starting from a representative sample and without sizing the solution only on tank capacity.
