Blasting of wood

From wooden furniture to oak beams to flooring and panels, the right grade of abrasive can bring wood back to its best.

Used in conjunction with a low-pressure blasting system, our range of abrasives can treat almost any type of wooden surface. This process can also be used to give wood an authentic aged look.

We’ve seen fantastic results with Bekagrit BG250, Scorex SC250, crushed glass, and our new fine-grade Vasilfine.

All of these abrasives can be used for both dry, wet and slurry blasting.

Whether wood is new or old, painted or unpainted, abrasive / grit blasting (sandblasting) is a perfect way to enhance appearance and bring items back to life. As with facade cleaning, it’s important to select the right type of abrasive blasting media to ensure good surface preparation without any damage.

As well as the products mentioned above, we’ve also seen excellent results with ground walnuts. This type of abrasive / grit blasting media is excellent for soft surface preparation, as it won’t cause any problems with etching. Ground walnuts are also biodegradable, making this a particularly environmentally friendly form of blasting media.

Please contact us today to discuss your abrasive / grit blasting (sandblasting) needs – we’ll advise you on the best type of blasting media for all of your wood restoration surface preparation requirements.

NAstra

NAstra® is an iron silicate (copper slag) abrasive. NAstra® is produced in accordance with DIN EN ISO 11126-3. It is a perfect blasting grit for blast cleaning steel, stone and concrete, and for the removal of mill scale, rust, old paint and dirt.

During melting of copper ore concentrates an iron silicate is formed. This is passing a groove and is granulated at a temperature of approximately 1250 °C, using a temperature-controlled pressurized water jet. After cooling down in a tank with fresh water, the fine particles are separated from the granulate manufactured in this way. It is a vitreous amorphous slag, it does not absorb water. During the manufacturing of the abrasive no crushing or grinding procedures are included. Therefore, the single abrasive particle is not broken up and retains its extreme hardness and tenacity which is the case for all particle sizes.

NAstra® used as blast cleaning abrasive for all application fields in conventional corrosion protection on almost all surfaces. It is suitable for surface preparation standards SA-3, SA-2½, SA-2 and SA-1. It is a non-hazardous material, containing less than 0,1% free crystalline silica.

ScorexPlus is accurately processed and sized and fully complies with ISO standards 11126-6 and 11127. It contains less than 1% free crystalline silica.

OK-grit

OK-grit is a granulated iron silicate. It is an iron silicate blast cleaning abrasive made with nickelslag from the Boliden Harjavalta nickel smelter in Finland where it is pre-screened. At Sibelco Nordic’s Nakkila plant the raw material is dried, screened into different grain sizes and the dust is removed. OK-Grit is suitable for a wide range of blasting applications and also as a high-quality granule for the roofing industry. The material is produced in accordance with ISO 11126-5 and 11127.

It is used as blast cleaning abrasive for all application fields in conventional corrosion protection on almost all surfaces. Suitable for SA-3, SA-2½, SA-2 and SA-1.

Very suitable for use as roofing granules, as it is weather resistant and has uniform colour and grain size.

Fajalit

Fajalitis a granulated iron silicate material extracted at Boliden’s Rönnskär copper production facility in Sweden through a unique process called ‘fuming’ whereby the silicate is exposed to high temperatures, resulting in a very pure product. After drying, the material is then sieved to an optimum particle size for blasting. Fajalit can be used on most surfaces and is produced in accordance with ISO 11126-3.

It is used as blast cleaning abrasive for all application fields in conventional corrosion protection on almost all surfaces. Suitable for SA-3, SA-2½, SA-2 and SA-1.

Very suitable for use as roofing granules, as it is weather resistant and has uniform colour and grain size.

Vasilgrit

Vasilgrit® is an aluminium silicate blast cleaning abrasive made of coal slag from coal fired power stations. Vasilgrit® is designed for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-2½ and SA-2, as well as SA-1, also called sweep blasting.

Vasilgrit® is a by-product of coal fired power plants and is an inert, natural abrasive that contains less than 0.1% free crystalline silica. Vasilgrit® is very accurately processed and sized and fully complies with ISO standards 11126-4 and 11127.

AbraVer Glass beads

AbraVer® is a non-metallic mineral abrasive, made of soda glass.

They are also suitable for inspection blasting (fraction and fracture detection) and for glare free, decorative matt satin finishing. Another application is micro peening. When using glass beads, there is no abrading or scouring action, no deformation of material and no contamination or embedment of particles. Glass beads are suitable for dry compressed air blasting as well as for wet blast cleaning.

Doloblast/Microdol Dolomite

Doloblast/Microdol is a natural calcium/magnesium carbonate-based micro abrasive used frequently for wet blasting. It is particularly suitable for the restoration of monuments and statues, façade cleaning, and the removal of dirt, paint and graffiti. Doloblast/Microdol contains no heavy metals, free crystalline silica or corrosive salts and will not cause efflorescence. Due to its low hardness, Doloblast/Microdol does not damage the blasted surface, instead acting more as a cleaning agent. It can therefore be used to blast clean glass and there is no need to tape off hard metals or hard types of paint (provided they are not oxidised or weathered). Aluminium, copper, zinc and thin layers of paint (latex, synthetic materials) will still need protection.

It is very suitable for restoration of monuments and statues, facade cleaning, and removal of dirt, paint and graffiti. It does not contain heavy metals or free crystalline silica and therefore harmless to health and environment.

Due to the low hardness of the material, Doloblast/Microdol does not damage the blasted surface.
