A pressure sprayer is an undoubtedly useful tool in the natural building realm, especially when working with cob or plaster. Sometimes a hose is way overkill, or simply not possible to rig up. A portable sprayer fills the void, and can be especially good when you want a lot of control. When you need to wet your walls down to lay up plaster, for example, it’s useful to have something that you can work with a certain amount of finesse, only spraying what you need and not saturating everything else in the process.
Over the years, I’ve burned through any number of pump-style pressure sprayers. You know the ones — the tools with the plastic tank and plastic handle that you pump for a minute, and then try to eek enough water out of the plastic nozzle before you have to pump again… annoying, to say the least. And usually pretty cheaply made.
However, I’ve been using this Hudson trombone sprayer for a couple of years now, and can vouch for it. It’s come in quite handy during all of the plaster work we’ve been doing lately.
