Chem Tank

[Trevor C.N 15]

I was hoping someone could give me advice on purchasing a chem tank and sprayer. I’m looking for a 25 gallon chemical sprayer to reduce the amount of time it takes me to mix chemicals on site. I typically work with sodium hydroxide (stripper) and brightener. I found a duel 25 gallon tank with a single hose (It has a control valve for tank selection). This seems like a good option for me, but i’m wondering if sharing the same hose would be a problem with these two chemicals? Should each chemical tank get a separate hose?  

Also, what length of hose is adequate for residential jobs? I need to make sure it can stretch far enough into most backyards.

 

Any better suggestion in mind? please tell!

I'm far from an expert in wood care. But I'm pretty I do kno sh is an alkaline and yur brighter us probably and acid so I definately would want to keep the two seperated. What kind of brighter ru using?

[Trevor C.N 15]

I use oxalic acid for my brightener.

[ckeener 30]

O yea u wanna keep them seperated. They would probably have a pretty good reaction if they were to come in contact with each other

It depends on how large the decks are . Stripper (sodium hydroxide) Is easy to mix in a couple of 6 gallon containers  for doing decks  and you can control the strength of the stripper better at the deck. 25 and 50 foot lengths of hose is good . Don't leave stripper in the hose! I have jobs wear a 100ft is needed. I like mixing at the site .  Powder acid mixes better in hot water.

 

Same hose for your purpose not a good idea. Also 25 gallon tanks are 150 pounds filled. Most decks I do i would have to run 100 to 200 feet of chem hose.

If your tanks are truck mounted you are definitely going to need 200 feet of hose. Make sure you inspect the hose often. Last thing you want is stripper spraying all over someones house, and not finding out until the damage has been done.

We don't do decks or wood care at all. Just curious do u apply stripper then powerwash?

Yes, but it is really power rinsing.  

[ckeener 30]

Ok. Could u downstream yur chems then?

You don't downstream stripper. It wouldn't be near strong enough and you definitely don't want sodium hydroxide (in strengths required to strip a deck) flying all over the place. You can however downstream the brightener/neutralizer. Usually stripper is applied with a pump up or 12 volt pump.

[ckeener 30]

Yea good point. High pressure sh is never a good idea. Brain fart I guess. How many gallons does it take for an average size deck?

Of stripper? Depends on what you are removing. It's one of those things you learn over time, because the coverage rates vary depending  on what your are applying to.

So Let's say I end up getting a 200 ft chemical hose that's mounted from my truck. When i'm done spraying the stripper, what would I do with everything that's left in the hose?

[ckeener 30]

We have a 25 gal tank we use for a few thing and it has a plug in bottom. If we have left over chem we just open it up into a bucket or container and then flush our hose with lots of clean water

If you are using a 12 volt pump, most of them can run dy. Just spray back into the tank for 10-15 seconds, then drop intake hose into a bucket of water. when you get to the air gap, you are done cleaning out the hose. This is how I clear out my oxalic acid, I use for hard water stains on driveways.

"run dry" Wasn't wearing my glasses.

Thanks! So  I can probably get away with using the same hose for all my chemicals, as long as i'm careful to clean the hose out before I switch it over?
