Sandblasting Profiles: What abrasive should I use?

Anchor patterns are extremely difficult to approximate due to the many variables at play.  Use this information with Caution!  This is only an approximation.

The type of metal use in this example was hot rolled steel with tightly adhering mil scale.  The type and hardness of your substrate, how thick the scale is, the degree of cleaning you are attempting to achieve, experience and skill of the person performing the sandblasting, etc will all factor into your end result.  In this example, the pressure blasting was done using a 90-100 psi nozzle pressure.  The depth of the anchor profiles listed below are approximations only, and are on average.

1.5 Mil Profile:

Using Crushed Glass To Clean Precast Concrete

Crushed Glass Used To Clean Precast Concrete

Armani Restoration Job SiteCrushed Bottle Glass Abrasive is used to clean and restore the exterior of this 27 story concrete building.  Using  a proprietary wet and dry blasting system, the contractor dramatically changed the surface color of the building, as you can see in the photo.  The concrete surface of this building was not smooth – it did have a texture to it, so a medium grade was chosen.

Crushed glass sandblasting abrasive is the perfect choice for either light cleaning of precast concrete, or by using coarser grades, exposing the aggregate in the concrete.  A medium grade was used for this job, as the customer did not want to damage the surface of the concrete.

Crushed bottle glass abrasive is a 100% recycled product, and is shipped from a variety of locations.  It contains no free silica, no heavy metals, is inert, and it blasts fast and clean.  Many times people will just leave it on the ground rather than clean it up (unless you are blasting off something toxic like lead paint or have local laws requiring cleanup).  Because this type of abrasive is shipped from all multiple points of origin, we will always try to find the closest location to your end job site when quoting.

Cleaning Bronze with Glass Bead Blasting

Here is a great video and article on glass bead sandblasting.

This company is using a fine glass bead to remove bronze patina from outdoor monuments, which restores them to their original state.  I would have liked to see some before and after photos of the monuments, but the article does contain a video clip where you can see (from a distance) the cleaned and uncleaned areas.

Workers from Sterling-based Mercer Lettering and Monument Works have been  sandblasting and pressure-washing the granite stonework over the past few weeks.  The granite stones also have been treated with an organic acid designed to  preserve the grass below while removing fungi from cracks in the stone.

On Thursday, they aimed nozzles at the bronze plaques and sprayed them with  fine glass particles. That removes the patina, or green and brown film, that has  developed on the metalwork over time without damaging the metal below it, said  Graeme Everson,  the company’s owner and a National Guard veteran.

“It brings back the shine of the bronze as it was when they put it up,” he  said.

The article does not discuss the size of the glass bead used, nor the exact machine they used, but the video shows the actual operator blasting.  You can therefore see the blast pot and the operator’s protective head gear which is useful for those just starting out and not familiar with protective gear.

Do It Your Self Sandblasting

Here is a fantasic business in Vancouver, B.C. that a couple of entrepenurs started recently. Do-it-yourself sandblasting! Now why didn’t I think of that?  Don’t we all have old furniture, rusted equipment, & gardening supplies that could use a facelift?

Everything from vintage metal toys and wooden chairs to bathroom tiles and car parts are being scoured clean at a Victoria do-it-yourself sandblasting company.

Customers pay $1 per minute (minimum 15 minutes) to blast their items, or $1.35 per minute (minimum 20 minutes) for a staffer to do the work at Blast It!, located in the Hillside industrial area at 2639 Turner St.

It’s easy. An item is placed inside a self-contained cabinet. Once the door is locked, a customer standing outside the cabinet slips his or her hands into heavy duty gloves which run into the interior. Turn on the control with your foot, point the nozzle of the wand at the item and the blasting starts. Continue reading
