Chapin Xtreme 3.5 Gallon Tri Poxy Industrial Concrete Open Head Handheld Tank Sprayer with Tri Lock Seal, 4 Inch Wide Mouth Opening, and Lock On, Red

This product works beautifully. I used it to spray patterned/stamped concrete patio about 700 square feet and it took me about 30 minutes including one refill. The entire process was a lot easier than originally thought. The spray was even and effortless. The sprayer is well made. The plastic holder to hold the sprayer wand is a bit flimsy.I had difficulty getting the sprayer pump to close and lock properly. That was not an issue with the sprayer but the instructions in the user manual. The user manual had instructions on how to close and lock the pump, but no explanation on the possible causes and steps to get it close and lock properly if it ran in to issues. I wasted an hour or so trying to fix the problem. I finally gave up and was almost ready to ship the unit back as being defective. The next day, I took it to a rental store renting the similar unit and the technician got it working within 30 seconds. The manual should include Frequently Asked Questions section and include this common issue.Another item to expand in the user manual is about cleaning the sprayer. The manual says to clean with water only. However, the rental store told me that you can use xylene or paint thinner or water depending on the solvent in the spray material you are using. I have not confirmed this with the manufacturer. However, the manufacturer can include better description about cleaning fluid and explicitly include/exclue other cleaning fluids.Since this is late in the season, I will try the sprayer on other spray applications next season and see how versatile this sprayer is. However, it worked beautifully for the main application I bought this sprayer for.

Just used it to apply degreaser to 5,000 sqft concrete -- AN OUTSTANDING PRODUCT! I was blown away by the quality as soon as I took it out of the box. Construction is beautiful. Viton brass nozzles (1 GPM and 1/2 GPM); long brass wand; brass trigger; brass barrel tube (for the pump) and corrosive-resistant interior. Durable steel tank and heavy-duty paint job.PERFORMANCE:-Super strong pump handle and spin-lock collar. Unlike other designs, this allows you to pump without accidentally unlocking the whole pump cylinder. Simple but brilliant.-3.5 gallons is perfect for spraying most areas. It doesn't weigh a ton, but you still get enough volume to avoid frequent refills. My whole job took exactly three canisters (50 minutes). Filled weight is 40 lbs; 10 lbs empty.-Large mouth with flanges lets you fill quickly. If you need to dilute, there are measuring grooves inside and out of the canister for easy measuring. No straining your eyes with those useless "see thru" gauges.-Excellent spray consistency for an unregulated sprayer. After the initial fill and pump, I only had to re-pump once.-Nice spray pattern, owing to the quality brass nozzles. What a difference over plastic!-Made in "America?" Whoever these people are, they build nice stuff. Don't bother looking for this at bLowes's or Home Despot.-Minor complaint: The wand/spare nozzle holder is somewhat flimsy plastic. It's awkward to use, because the hose is heavy-duty and fairly stiff. Still, it's better than nothing (which is what most other sprayers offer).If you're tired of toy poly sprayers with bum nozzles, inconsistent pressure and triggers that get stuck in the open position...buy this! It's an amazing value, considering that it will probably last longer than you.

Wow... what a lifesaver. I used this to apply Sherwin Williams HC Paver Sealer (xylene solvent based) and it did wonderfully through all 20 gallons. With my wife helping to backroll the spray, it took about 2-3 hours to do a 100 foot long driveway (2 car wide), turn around, front porch, and pool deck. Not only did it provide a nice spray pattern (using the 0.5gpm tip) it also used about half of the material that I used two years ago rolling it by hand. Paid for itself by saving me more sealer at $30-40/gallon and cleanup was quite easy. As an engineer, thank you Chaplin for building a quality product.The bad? The fan spray pattern was not perfecly even (heavier at the ends) and you really need to pump it up. Additionally, the black paint and metal used on the lid could be more durable. Will still likely get many used with this.

The product works great, quality made, I used it for sealing my driveway, great product, I do recommend it, I was disappointed on the shipping, it was shipped on its original box with nothing to protect it from dents, mine came with a sharp dent through the box as you can see in the pictures, this product needs to be shipped into another padded box to protect it from getting damaged.
