The blasting nozzles we were using here was a 3/32" Tungsten Carbide nozzle. Our nozzles are attached to the end of our Blasting Hose which is feed from the bottom of our Pressure Pot. Our Pressure Pots are attached to our cabinets which allow for unique self-contained recyclability of the blasting media. We also sell these Pressure Pot's as "stand-alone" system for on-site work or using with existing blast cabinets. See: www.rayzist.com/Equipment/PPot.php or visit Rayzist.com "equipment"

Rayzist manufactures photoresist film designed for Sandblasting; our sand resist product often requires additional adhesive when blasting onto non-polished surfaces like natural stone or honed granite. We use our blastable adhesive RZ2; we would also use 'heat' on the surface of the stone to help activate the bond between our photomask and stone surface.

We do not use vinyl. Our resist film is a photoresist; unlike vinyl its an image reproduction process, so there is no weeding to the image. The adhesive we are using is our product called RZ2 adhesive. Found at Rayzist.com

not to mention the sheer amounts of hand lotion she must use up.

I know it's cutting through brick and yet her hands are not protected. How dumb is that

Here's a trick I learned in the army: just sandblast the brick, not your hands. You're welcome.

Hello Dave, Thanks for reaching out. Rayzist does have the ability to make stenciling for you through our Custom Mask department. We can apply a "heavy" adhesive coverage on 9Mil photoresist film. We can produce a single mask that is up to 42" x 42" before you have to register a second mask. Email/upload the file (design); four days later, we will send you a premade stencil(s). I suggest we do a spec sample (with heavy adhesive) before we go into production. Beyond having the surface clean, heating the surface will cause the photoresist to draw down onto the surface of the irregular stone. Please check out a few of our videos on the "Learn Sandcarving" playlist. Rayzist.com

Thanks for watching; this is a very old video.... When determining blasting pressure and media size, it really depends on the "resist" you are using. As a photoresist manufacturer, we have thinner films, as seen in this video, and thicker films, which will withstand coarser abrasives and higher blasting pressure. Using thinner photoresist film and lower pressure just means the "depth" into stone will require more passes to achieve more blast depth.

+Mike Connolly Thank you, no gloves, fume hood not turned on

The photomask used is ONE mask. The purpose of this particular video was to illustrate, "if required" a thinner 4Mil mask could be used for a paver brick. We would suggest the use of a thicker photoresist mask mask for production. Most "walkway pavers" do not require too much blasting depth so a thinner photomask can be used, again if necessary. If significant blast depth was required; you could double the mask if you had to.

Sandcarving Thank you.

Hello Ron, thanks for your comment. Obviously, this does not hurt or harmful in any way. You are assuming this process is an industrial one with course media and it’s quite the opposite. Although we use a pressure blaster the blast media is quite fine and does not hurt your hands in any way.

gr8deals2do Our products are perfect for slate and all natural stone blasting. The minimum air requirement would be a compressor delivering minimally 5.5CFM if sandblasting at 30PSI. Sand blasting stone could require higher pressure to achieve depth faster. Yes, we do have our products available from our partner company in the UK, The Glass Scribe. See: www.glassscribe.com you will be able to get product, pricing and support.

Yes, of course, you can Sandblast onto the granite and all types of stone media. Etching time is relevant to the 'thickness' of material you are using, blasting media size, blast pressure, and depth you are trying to achieve. This is a difficult question to answer. Might I suggest you visit our KZfaq channel and see more the recent videos, KZfaq.com/Sandcarving (perhaps our monument videos)

Yes you can. However building brick often has a lot of aggregate which is much harder to achieve an even blasting depth and often does not show good image resolution unless your design it's very bold.

Hello Aaron, this video was primarily done really to show that you "can" blast a paver using a 4Mil photoresist stencil (note this is a clay paver and concrete pavers are much more aggressive as soon as you break through the surface) In truth, you really should be using a thicker resist, if at all possible so you can blast more aggressively (higher pressure or slower blasting strokes to allow the blast media to achieve depth quickly) 5Mil even 6Mil is preferred with using our SR2000 or SR3000 films. Lasermask as eluded to in the video has resistant strength equal to 5Mil+! Explore Rayzist sandblasting film for your next photoresist order. Rayzist.com

Appreciate the comment and for watching. We do recommend personal (latex) gloves, but they are personal preferences. Unlike industrial blasting the blasting grain is very fine and not harmful; secondly, the nozzle we use is very focused, so the blast stream is narrow. The point of our clips is a demonstration on a process, but there is nothing wrong with wearing gloves.

Thanks for watching! Please take a look at some of our newer videos, see the "Learn Sandcarving" playlist.

Hello Jeff, very thoughtful question. The resist used on Rayzist's photoresist films is a blastable adhesive and had little resistance strength. Photoresist film like the SR3000 Self Stick film, actually has no adhesive in the open area, the product is simply "Self Stick". Thanks again for the question.

Certainly would not want you to do that.. Paver simply indicates a walkway stone that would/could be personalized rather then a brick they you would build a wall with.

Hola Miguel, no estoy seguro de a quién puedo recomendarte también. ¿Dónde están ubicados?

Thank You Michael. Liz is blasting using a 150 grit Alum Oxide, which is a fine blasting abrasive; not harmful to your hands nor is the media aggressive. For sanitary reasons protective gloves in our systems are more personal preference between rubber gloves and or lighter weight disposable latex. Often times engravers using finer blasting media choose not wear gloves.

Sandcarving do you need to wear gloves with 150 or 180 grit?

4Mil = micrometer (thousands of an inch) or accurately 100 µm We do have photoresist film 9Mil & Monument grade film. What's being referred to in the video; if using LaserMask (which is 4Mil), you can lay down two layers for added resistant strength. You can apply as a blastable adhesive (RZ2 Adhesive) to LaserMask or photoresist film for added adhesion. see: Rayzist.com for more details on our product range

If you had invented it back in 1983, what would you have called it ?
