I talked a little about protective gear you should wear before, but wanted to go more in detail about sandblasting hoods. Some people call them blasting masks, suits, lens or helmets.
The main reason I wanted to make a post about these is I think that anyone who sandblasts outside without a cabinet should wear one of these blast hoods.
I can tell you that I have sandblasted a few times outside with the below gear and it is such an uncomfortable messy experience and not recommended.
My Old Protective Sandblast Gear
- Dust mask
- Eye goggles
- Ball cap
- And later on I would place the cheapie sandblast hood (which comes with most systems like this) over all the above for added protection.
Those cheap masks that come with many pressure pot systems aren’t the best but it is better than nothing. I suspect many people might not even use them or throw them in the trash.
New Low Cost Protective Blast Route
Anymore, I recommend you use a better sandblast hood or at least an economical hood. There isn’t really a reason not use them since many of these are fairly economical. I think most people will be happy they did.
I’ve seen some of the air-supplied helmet systems cost upwards of $1,000+. That of course would be the best option but more ideal for someone that blasts frequently.
Since many folks only sandblast occasionally, the next best route is to try out one of our economical blast hoods which can be found on Amazon here. It will ensure an more enjoyable sandblast experience without the high cost.
A Must Have Accessory with Blast Hoods
These sandblast hoods provide some nice comfort in preventing abrasive from hitting you in the face, getting stuck in your hair, eyes, ears and mouth. It really does suck when these aren’t used!
But there is one problem that these hoods have that sucks too… Fog!
Anti-Fog Spray Method
When you are breathing inside a hood, the water vapor from your mouth will fog up your lens within a minute, rendering the hood almost useless for seeing. But there is a solution that you must get to solve this and that is anti-fog spray.
You can find all types of this anti-fog spray here. It isn’t overly expensive either and is an absolute must if you are going to use sandblast hoods, or even any goggles for that matter.
Extra Dust Mask Method
Another suggestion is to use an extra dusk mask inside your blast hood for two reasons:
- Provide better protection from inhaling sandblast dust. Some dust will always find its way inside a hood. Our sandblast hood has a simple diaphragm valve which controls the intake and exhaust of air through the lens. Even though it prevents a lot of dust, it doesn’t keep it out 100%. Dust will add up when blasting for a long duration.
- Hinder the fog & water vapor from accumulating on the lens. A good amount of the hot, humid air coming from your breath will get caught on the dust mask in between your mouth and lens.
In my opinion, the first point with the addition of another dust mask is important. Be sure to at least use a simple dust mask or a dual respirator filter mask if you can find one that will fit snug inside.
what is the very best way (if any ) to clean / polish a plastic lens after damage from sandblasting some time so you can see through it again
@ Ted, usually you would have to replace it. However, if it is something that you need to salvage, you may want to try one of those headlight polishing kits like here: https://amzn.to/3zhvOYY
I wonder if those ceramic coatings would even fill in the pits and restore it. I haven’t tried either of these but they are ideas to try. See here for what I was thinking https://amzn.to/3csEkLJ
I always recommend using a plastic film on blasting lens, then pull to remove and replace with new one when needed.
