I'm considering buying a spray booth

[Guest]

airbrush-pro.co.uk

Click on "Spray Booths and Filters" at the left.

I am a beginner so don't want to lash out too much dough yet. I thought of making one from 1/2" chipboard and a 6" desk fan, but it would cost about 2/3 the cost of the above, including the hose, and quite a lot of work.

Is this one worth having?

Are there any others worth considering?

Thanks.

As a beginner i wouldn't splash out on one just yet personally. Unless you are spraying somewhere in the house that is close to others. I spray in a spare room in our house and always wear a mask personally. Cannot justify a spray booth yet

[Guest]

Thanks, flounder_al. What type of mask do you use, type, and where is it sold?

In theory, (my guess) no mask can prevent you breathing solvent vapour. Its a gas and mixes with the air. This implies that only a scuba-like compressed air tank system could be totally safe. But that's being rather obsessive!

Yes I have one of these booths Steve & they are very good.

But they are not wide or high & for instance you would never get a full 1/72 Lancaster in there or probably many if any 1/48. Think you can get an extension kit which doubles the width.

I spray in front of mine. Also I found if I used the extractor, it works fine, but it pulls air through including all the small hairs in the air. Guess where they land. Tried it again only last week & hairs !!!!

On masks. I use Vallejo paint which are specified as non toxic so that is a great help. But spray gets all over in very small droplets not noticeable on skin etc but you can feel it in your nostrils so it is a good idea to have a mask. But you need to get the right mask if you need it to do the right job. Mine have two filters at the front about 2.5" dia. These are removable for replacement. You need, if you want the best mask & filtering, a manufacturer who does a series of filters each performing a specific task. You can then get the filters to match your task.

You are right some does get through but a lot less.

That's not correct and is an important cosideration when buying protection. Many respirators (like mine from 3M) do protect you from organic solvents as well as small particulates and aerosols.

I can't check the numbers on mine as I'm not at home but any reputable supplier should be able to explain the various grades and levels of protection.

make one out of wood. im in the process off doing it right now.

if wood is too heavy you can buy plastic sheets from ikea or b and q. fit a light inside it, simple.

Or use a card board box on its side.[ATTACH]53306.vB[/ATTACH]

And when your not spraying you can pretend to be a storm trooper and play star wars with the kids

Any decent Mask with a close fitting nose/mouth cup and an active carbon filter will catch 99% of all the nasties. Just check that the filters are organic solvent safe. Also when not using the mask keep it in a closed (air tight) bag of box. Active carbon filters degrade in the air and lose their protectiveness quicker if just left out in the open.

When making a spray box. Just make sure that ALL electicals are gas safe.

Good advice Ian. My mask came with a resealable airtight bag.

You are not helping John :laughing:

Despite having all the correct filters in a half face mask you will not get anything like a 100% filtration.

First the mask has to fit tight to the cheek/nose the chances of that being achieved is very small indeed & reduces with age.

Secondly the air extract mechanism is primitive & although probably fair for a short time of its life but will then draw in some contaminated air in on each interval of breathing in & out. Do not know of any half mask with a filter on the out air.

A full quality face mask will to a great degree reduce all the above problems. A good spray booth will have face masks with a respiratory air flow connected bringing in out side fresh air.

The use of the more sophisticated units tells that a face mask is a primary defence. When I started with enamel Humbrol I used a good quality half mask with the specified filters for turpentine substitute thinners & I could still smell some thinners in the mask. There was also a smudge of paint around the out valve. The reason I went to Acrylics.

Not suggesting a face mask or more sophisticated efforts for intermittent use. But if you have any breathing difficulties then care is really needed with the use of a half face mask plus the materials used to airbrush.

I do that to keep kids out of my den

Scares the crap out of them :lol:

I sprayed an entire 1/48 airliner with Alclad,very pongy stuff,wearing this mask or one similar,using an extractor as well,and didn't smell a thing......until I took the mask off.

You can see the spray booth behind me and the exhaust hose seemingly emerging from the top of my head before exiting the window.

Assuming that I get a booth some day, a question on where to expel the fumes. The booth is designed to expel via the flattened end of the hose pushed into a 1" opening in a window or door. In my case it would be the window in my spare bedroom which is in the roof space (but of course enclosed by walling). Opening a door or window would make it cold in Winter.

How is this for a crazy idea: poke a hole in the bedroom's plasterboard wall and expel into the rest of the roof space. Although I would not be doing long sessions of airbrushing, would the build-up of enamel thinner vapour cause a fire hazard? (The blurb advises expelling into a door gap. This implies a door leading into a possibly internal landing or stair.) The roof is tiled without any tarpaper lining — its a 1925 bungalow — so the roof space is quite well ventilated.

Crazy idea, or lateral thinking?
