We tried using the clear Thompsons Water Seal with this sprayer and the fan tip kept getting clogged. We could never get the fan tip to actually work unless we had plain water running through it. We ended up having to return the sprayer.

Rated 2.9 out of 5 by 68 reviewers.
Rated 4.0 out of 5.0 by Best Deck Sprayer Easy to assemble, has an even spry. Easy to clean and store away. June 10, 2014
Rated 1.0 out of 5.0 by Not a good product I purchased this sprayer for semi-transparent stain. As it states on the box and instructions, this sprayer is capable of handling this type of product. I loaded the sprayer and all it would do is spit a large amount of stain. No even coat and wasted more time than it's worth. I tried to adjust the nozzle and everything and same results every time. I do not recommend this product. May 22, 2015
Rated 2.0 out of 5.0 by The Product is a White Bottle Both The Website and the packaging show a black plastic bottle, I ordered 2 of these and both arrived with white bottles. One had a defective pump. I have contacted Home Depot about the wrong color shown on the site, they advised that they would send a message to their IT department and it would be taken care of in the next few weeks or so.

Rated 2.0 out of 5.0 by Not the best sprayer for semi-transparent stain The RL Flo-Master sprayer model 1125D is recommended for various Behr products with one of them being semi-transparent concrete stain. I tried using both of the nozzles included in the box (poly and brass) and the spray did not come out even or in a fine mist spray, it sprayed hard on the outside edges and light in the center. The label on the can mentions to apply the stain using a "high quality pump sprayer at a fine spray setting". I can't say this was a high quality pump sprayer. There are 2 positive features of this sprayer, the pressure release switch on the side and the continuous spray option on the wand. A better option to consider is using an airless electric sprayer.

Rated 2.0 out of 5.0 by CAREFUL: DESCRIPTION OF PRODUCT IS INVALID MANUFACTURER SAYS IF YOU USE THIS PRODUCT TO SPRAY BLEACH, THE FIVE-YEAR WARRANTY IS AUTOMATICALLY VOIDED! Ordered this a couple of weeks ago. I wanted a large capacity unit I could use to de-mildew about 150 ft of brick walkway, and the web description indicated this would handle that chore. When I received it, I got two surprises: Positive: it comes as a translucent body rather than black, making it easier to see how much liquid is in the tank. Negative: the box and the user instructions explicitly state: do not use bleach in this unit! I contacted Home Depot Customer Service by "live chat" first (a 45 minute chat), and then via email, and received the usual: "We'll record your concerns in your account file". I called the manufacturer who verified that indeed it is not to be used for bleach and to do so voids the warranty. The bleach apparently erodes the seals in the unit, though it is possible to order replacement seals. I decided to keep the sprayer because I need the volume capacity, reconciling myself to having to scrupulously clean it after every use, which includes having to disassemble the pump unit to get at and dry the seals. Funny thing, all this appears to have been filed away somewhere in Customer Service, because the website still makes the invalid claim... April 11, 2015
Rated 4.0 out of 5.0 by Good Product This is a good product for the use this I purchased it for. February 7, 2015
Rated 5.0 out of 5.0 by Makes Staining Much Easier I bought this to try. It's only $20 and if it didn't work, it was worth the money to try it out. Overall, this made applying stain to the deck quicker and easier. There are some precautions though. If there is any wind, be careful for over-spray on bushes, landscape or the house. The other precaution is more of a notice, the sprayer does go through more spray than the conventional brush. Just keep that in mind. If you want to save hours, buy an extra gallon of stain!

Rated 3.0 out of 5.0 by Owned for 5 years This sprayer worked well however the wand is not the best quality. If you purchase consider replacing wand with a brass one as this plastic one will not hold up to time. Either that or find a sprayer with a brass wand that comes with it. The wand began to leak heavily from the area you hold with your hand after owning for a couple of years and it was only used about 5 times. November 25, 2014
