FAQ

What grit can I use?

All the grits you want BUT

Stick in the beginning to 0.2-0.5mm (there is a conversion table on the website)

Do NOT use cheap white sand that you buy for your children to play in. That sand, when it breaks or is blasted, releases silicata which is EXTREMELY dangerous

We have good experience with Metabo grit Aluminium Oxide, available on Amazon and others

Can I use other grits outside the 0.2mm-0.5mm range

Yes, the BLSTR sander will not get damaged. We recommend that in the beginning you stick to the dimensions above. To get a good feeling of the BLSTR sander. Later you can experiment. Finer grit will however create lots of dust. Thicker grains can cause blocking (and then you need to clean it).

What's the difference in performance with compressor sandblasting?

There is none. The disadvantages of a compressor beside being big, bulky and loud, is that it loses power (pressure) very fast. WIth a 10BAR 100Liter compressor you will very quickly be at 8BAR, once you have started. Then you will have to wait until pressure is back to 10BAR.

The blasting itself is quite the same. It takes off the paint and rust with exactly the same ease or effort.

Why not with a battery?

It will one day.

What types of materials can I sandblast with the BLSTR sander?

The BLSTR sander is versatile and can be used on a variety of materials including wood, metal, glass, and brick. It’s important to select the correct grit size and adjust the sander’s settings according to the material to ensure optimal results without damaging the surface. Always try first a small part to see if the result is what you want.

How do I clean the machine

Once in a while you need to open the top cover (3 screws at the top) and remove it together with the metal topcover (to assure the tube is kept in place). When it's open, you can clean the tube with a cotton stick and remove the grit from the centre of the impeller (the part with the 6 blades in).

When reassembling the top, make sure the tube runs through the plastic and metal cover AND make sure the end of the slider (with the 2 pins) is well inserted in the fork that controls the gritflow.

IN "MANUALS" YOU CAN FIND PICTURES HOW TO OPEN THE TOPCOVER

You do not need to unscrew the blades in the impeller!

The body of the machine (with the motor in it) should never be opened nor cleaned!!

The BLSTR sander starts fine but then grit stops flowing What can I do?

This issue could be due to a blockage in the grit feed system. Ensure that the grit container is not only filled correctly but that the grit itself is dry and free from clumps. Blockage can be caused by humidity. Check the feeding tube for any obstructions. Verify that the grit flow regulator is properly adjusted according to the manufacturer's instructions.

You can open the top of the machine via the 3 screws on the top. Remove the plastic top cover (together with the metal plate!) and then you can check the tube and clean the inner part of the machine from cluttered grit. When putting it all back together make sure the small tube is going correctly through the metal topcover AND that the sider (with the 2 pins at the end) is well inserted in the fork above the handle).

Can the beam or gritflow not be more narrow?

No, we tried but unfortunately physics does not help us. That's the way the tool works. Once you get the feeling of BLSTing, it doesn't bother you anymore.

The advantage is (compared to traditional sandblasting with compressor), the surface is blasted wider/larger (no deep spots) and you get smoother results.

In the manual it says not to open the machine, but how can I check the blades etc?

Not opening the machine refers only to the body of the machine. Do not open this body and if this is broken you need to contact us.

The upper part of the BLSTRsander can be opened to replace, check, clean etc. the rotating parts. You can compare these parts as the replaceable parts of a grinder

Unscrew the 3 black screws at the top and you have acces to the impeller (=the 2 aluminium plates that keep the 6 blades in place), the metal topcover (with the slider inserted in it) and the plastic topcover with the tube.

Make sure that when you assemble the tool again , the tube goes well through the metal topcover, that the slider is well in place and opens/closes correctly and that the slider- end is well inserted into the "fork" that guides the gritflow.

N "MANUALS" YOU CAN FIND PICTURES HOW TO OPEN THE TOPCOVER

I opened the upper part of the machine before I used it myself and there is grit inside. The machine is used!

correct, we do a very small test before packing everything.

It is a brandnew tool and we are still learning/optimizing and to avoid you receiving a BLSTRsander that does not work propperly, we test with a small amount of grit to be sure. It makes our production process longer and more expensive, but we want to deliver a good machine that you can enjoy for a long time.

However, inhouse Quality Control is still not the same as real usage by you. So, yes there can still be issues. Forgive us, we do everyting to improve. On a daily basis. If it is the case please contact us, and we will find a good solution for you.

The little screw on the left side of the machine (upwards), do I need to use it? How to assemble the handprotection guard.

Yes, you need it to fixate the handguard to the machine. In that way the handguard is fixated on 2 points (the handgrip and the little screw).

If only fixed with the handgrip, it is not stable and will break off.

Can the BLSTR sander be used for wet sandblasting?

No, the BLSTR sander is designed for dry sandblasting applications only. Using it for wet sandblasting can damage the internal components and void the warranty.

Why does it cost more than an average anglegrinder or drill

We use very abrasive resistant components on the inside to avoid the tool being eaten from the inside. These ceramic parts are not very common, and certainly not in this shape. Therefore it is very expensive. Also, as we are not a big multinational like the well known brands, we don't get to benefit from economies of scale. Not yet :-)
