Chapin 19249 Made in the USA 3.5 Gallon Dripless Xtreme Concrete Open Head Sprayer for Professional Concrete Applications with Unique Tri-Lock Seal Feature, Red

Chapin 19249 3.5-Gallon. Nice rugged construction. Yes the holder for the wand is flimsy plastic but I don't use it so not an issue for me. The rest of the sprayer is very heavy duty. I sprayed Armor 500 sealer on my stamped concrete with it. Bought the adjustable nozzle too. Better than the ones that come with the sprayer. Cleaned sprayer with half quart of xylene as per clean up instructions on sealer. Does great job.

Used it to seal my driveway and I used a water based sealer instead of the resin based sealer which was double the price and through my experience in the past. The resin based sealer didn't seem to last much longer on my driveway than the water based. But, this will be different from person to person. The plastic holder is very loose and come off with the slightest movement. Other than that the unit itself is easy to use and works very well. Just make sure to clean it thoroughly after using it. I used acetone to clean mine out and then a good rinse with water in the tank and the wand. Only time will tell how long this sprayer will last but, it should definitely last for many years to come as long as it's cleaned after each use.

I tried to get this working for several hours and really wanted it to work as I need a good long term sprayer for sealing our concrete every few years. Couldn't get it to pressurize and finally noticed the threading was not catching in the pump - see pic which I believe is required to make a proper seal. Looked on the website and couldn't find anything about how to get this to properly thread so it would pressurize. Finally gave up and used a plastic low pressure pump to complete the job. I cleaned it, packed and sent back

My brother-in-law lent me his Chapin Xtreme Sprayer (Model #19049) for the weekend. Suffice to say, I was quite impressed with it and so I decided to buy my own (Model #19249). However, you do have to take care of these tri-poxy-coated tanks. The coating will deteriorate/flake off and the tank will then rust if you don't maintain it properly. I would HIGHLY recommend storing the tank inverted so that it dries completely.Something I didn't quite care for was the spray wand holster. I appears flimsy, but it remained perfectly intact on my bro-in-law's tank, despite several years of use. Keep in mind, Model #19249 is equipped with the straight-shaft wand and comfort-grip handle. The holster is primarily designed to retain the curved-style spray wand, but you can still hang the straight-shaft wand on the holster's hook. In my case, I don't plan to use the holster much, as the tank will remain inverted during storage.Overall, if you take proper care of this sprayer, it should last you a very long time.

Solid & dependable. So far I've used it for 2 jobs -- applying Thompson's Water Sealer to about 1200 sq feet of concrete, and separately, applying about 2 gallons of RoundUp herbicide to various weeds. Works fine in both cases. Even with 3 to 3.5 gallons of liquid in it, it is not difficult for a man in ordinary shape to carry around (by the solid metal handle, locked onto a solid metal collar) while using the sprayer. Functionally this device is 5 stars - the only reason I gave it 4 is that the included plastic holster for the spray gun is flimsy and under-designed. It works, but just barely. If it was 3 times thicker & stiffer it would match the rest of the build quality but as it is it seems like an afterthought.Some hints for use & for longevity:1) If a consistent, even spray pattern is important for your job, be sure to keep the pressure quite high. As soon as the pressure drops below ~75% I found that the 1 edge of the "fan" spray started to get dribbles & heavier coverage.2) The user manual says "remove pump & store unit upside down when not in use." You really do have to do that to get it to dry out. Even a few drops of water way down in the bottom will stay there for days or weeks, unless you live in a desert climate. This steel tank is "triple poly lined" but as everyone knows, water + plain steel, even coated plain steel, is no bueno in the long run.3) What the manual doesn't mention is that in order to get all the water out of the feed pipe & hose, it's best to remove the pump assembly, invert the unit, & hang the hose & gun below the level of the upside down tank, and hold down the trigger until everything drains out. Otherwise the several tablespoons of liquid trapped in the feed tube & possibly the spray hose slowly dribble into the tank over days & weeks, keeping everything damp inside.4) What I do to greatly accelerate & complete the drying process: After a 1st (or 2nd) rinse & spray-out with water & a bit of soap, I do a final rinse with about 2 cups of 90% isopropyl (rubbing) alcohol. I'm sure 70% would work fine too. This evaporates much more easily & quickly than water & leaves everything bone dry. Paint thinner could also work but I don't use that as it may tend to leave residues or oils in the tank / tubing that I don't want in there.

I purchased this because a client wanted a solvent sealer used and typical sprayers can’t handle the material. This was able to spray the solvent through the larger tip. However you have to ensure the seal is good on the can and it does take a fair amount of pumping. You need high pressure to spray thick material such as a solvent. So while it does do what it’s technically suppose it by no means makes the job easier.

Fantastic worth every penny... Got tired of low cost plastic sprayers from local hardware stores - every year need new one or tape old one together. This is a solid industrial grade sprayer. Comes assembled ready to go in the box with two spray nozzles. Arrived, I opened box and five minutes later poured in 1.3 gallons of Ortho spray and covered 800 sq feet of patio in about 15 minutes - Held pressure for entire 1.3 gals. Easy to handle with grip and and wide area spray. Nothing shabby disagree about others who said plastic holster junky - was rugged and holds nozzles.
