I'm helping a contractor seal a hotel in Charlottesville Va with a siloxane based sealer. He wants us to spray the material with our airless sprayers. I'm not keen on the idea due to liability. We have pressure rollers that we can use but the material says it should be sprayed to the point of flooding the brick. My thought was to use a backpack type garden sprayer. The problem that I'm running into with that is all the sprayers that I've looked at say, "do not to spray flammable materials" (which this product is). Is there a brand of backpack or other type of garden sprayer that can be used with flammable materials? And what is the reason that a flammable material cannot be used with this type of sprayer? Static charge? Any help is much appreciated. I'm new to the site and haven't figured out how to fill out the bio page. Thanks!

I think the reason you aren't supposed to put flammables in a pump up is that the tank pressurizes. Dangerous.
What's the problem with using the airless? Too much atomization? Could shoot it out of the back of the tip, no cloud of mist just a stream. Works better with Titan reversible tips that the Graco brand ones. Try it with water first.
