Questions & Answers

can you spray on with a sprayer

Asked by: john
No! The new milky white water based product works OK in the sprayer but will go on too thick and stay sticky for weeks.

Can this be used is a garden/pump type sprayer?

Asked by: Woody
Yes. I would HIGHLY recommend you purchase a quality sprayer such as the 2 Gallon DB Smith Contractor Pump Sprayer, Model #190216. Cheap sprayers will usually clog at some point and do not normally provided the option of adjusting the spray pattern/mist. The DB Smith sprayer is extremely well built, has multiple spray nozzles included (I suggest using the “red” high pressure one), easy to use and clean. It is reasonably priced considering its level of quality. I just submitted a detailed review that may provide additional application tips.

can it beused on pressure treated wood
Asked by: 69nova
Yes. Pressure treated wood can still dry out over time. I recommend applying it every 6 months. Unless you're in a climate that dries it out quicker. Then you may want to do it every 4 months. A simple squirt gun test can help determine if it's ready. Squirt a small area and if it soaks in and darkens the wood instead of beading up you're ready to reapply.

There seems to be a love it or hate it situation with wood protectors. I put this on new pine fencing. Read good tips for using a sprayer, the best being to make sure it is as warm as possible to help thin it out. It did happen to be 100 degree the day my wife and I rolled it on but we ended up just using a 3 foot diameter kiddie pool and sliding it along as we went. Worked well give the volume of product you are dealing with verses filling a painters tray about every 2 minutes. This worked well but plan on getting some on you. If you use a fluffy "rough surface" roller it is going to fling it around pretty good when you are loading it up with the product. Comes right off with soap and water as far as I can tell. Visually the fence looks great. Really darkened the pine and brought out the details. Will see how it looks after a season but honestly with EPA regulations I don't think there is anything better to be found.

I’ve used Thompson’s products on my wood fencing over the last 40+ years of various home ownership. This current review is based on the most recent purchase and use of the product on my daughter’s newly installed wood fencing. Details as follows… Fencing type: 6’ x 7 ¼” Rough Cut Dog-Ear Cedar. Fence condition: Brand new, untreated wood. Total square footage sealed: 2,356’. Application method: 2 Gallon DB Smith Contractor Pump Sprayer, Model #190216, in conjunction with a Linzer 5” flat stain block brush, Model #3350-5. Amount of Thompson’s Sealer used: 9.5 Gallons. Average square footage per gallon: 248’. Total amount of time to seal (including preparation, application and equipment cleanup): 9.5 hours. Climate Location/Details During Application: Southern California – Temperate. Sunny. 77 Degrees F. Applicator: “Old Dude” - 60 years young. First to address other review comments regarding the length of time this product lasts, and some of the negativity implied with that. This product is not marketed, advertised or designed to last indefinitely. I know of none that will. YES, you will have to reapply at some point to continually achieve maximum protection. My experience has been roughly at the 2-year mark. I consider it to be a part of routine/preventive maintenance on the fencing investment. With that said, it IS part of the consideration when purchasing. If you want minimal maintenance and a much longer finish, I suggest you PAINT your fence. In this instance, the main desires were to provide UV protection, prevent water and mildew damage, and maintain the natural color of the wood. Hence, the clear coat version of the product was used. For what it is designed for, this product works well and is reasonably priced. Board preparation is critical for proper penetration of this product. In this case, the boards were new and recently installed. As such the only preparation needed was to brush/sweep dust and dirt from the boards using a corn broom. Boards previously sealed or stained with another product, or old, dirty, untreated boards will require additional cleaning and preparation time. To begin the application process, I hand applied the sealer on the top “dog ear” portion of the entire fence using a brush. This ensured adequate saturation AND ultimately expedited the spraying process for the majority/flat portions of the fence. If you are going to apply using a sprayer, I would HIGHLY recommend you purchase a quality sprayer such as the one listed above. Cheap sprayers will usually clog at some point and do not normally provided the option of adjusting the spray pattern/mist. The DB Smith sprayer is extremely well built, has multiple spray nozzles included (I suggest using the “red” high pressure one), easy to use and clean. It too, is reasonably priced considering its level of quality. Addressing another common negative review aspect, regarding application with a sprayer. If you simply try to “spray and walk away”, meaning do nothing BUT spray on the product, you WILL encounter uneven saturation and/or runs. Got news for you…you will encounter that phenomena with ANY product you spray on in such a manner. Particularly with uneven, rough cut wood fencing materials. From both a quality of application AND final appearance aspects, it is best to immediately follow-up the spray on application by brushing in with a napped brush. This works the product deeply into the wood grain, particularly in between the board seams AND enables you to smooth out any over-sprays or runs. For me, what worked best was to completely spray four fence boards at a time, (roughly 174 square feet), then to immediately work those boards with the brush. Once done with those boards, repeated the process, until completed. In conclusion, I was completely satisfied with the end results, as was my daughter. I hope this review helps the “DIYer” in determining if this product is right for you, as well as provides application considerations and suggestions.

We bought a new house which came with a new fence and in order to protect the fence and maintain the color of the wood we bought Thompson's WaterSeal. The WaterSeal was easy to apply. We got one of those spray bottles which you are able to pump air into and apply the the WaterSeal. Our fence was a decent size and so we used about 2 of the 5 gal cans. The fence is currently maintaining it's original color and the wood will be protected and keep longer than if not treated. Definitely looks better that the neighbors. So far so good and I happy about my purchase. Home Depot associate was very knowledgeable and helped explain how to apply the WaterSeal and everything.

Rated 5 out of 5 by from Pump-Sprayer Issue Resolved - Thicker formula DOES spray! This is a detailed review which contains information on the project, preparation, difficulties encountered and a resolution. To bypass the lengthy review please scroll to view the summery. After studying feedback and comparing prices, Thompson's Wood Sealer appeared to be the best bang for the buck. Negative reviews were read concerning Thompson's thicker formula and its inability to be sprayed via pump sprayer. However; it was decided to give the product a try based on the good-to-bad review ratio. The project: Sealing 250 lineal feet of a 6' high shadow box fence. 1500 square feet total. For preparation, Berh All-In-One Wood Cleaner #63 was used the weekend prior. The directions were followed on the back. It took (5) 1 gallon jugs of cleaner and 8 hours of pressure washing. This made the wood look new. The fence dried beyond the 48 hours recommended by Thompson's. Doing so ensured the fence did not contain moisture. The initial sealing test: To start, (1) five gallon bucket was purchased from The Home Depot. Additionally, a Flo•Master 885-021 2 gallon pump sprayer was obtained. The gentleman at the paint desk machine-shook the bucket since the pour outlet did not support traditional stir-sticks. The first usage took place around 6:00PM on Thursday September 22, 2016. The temperature was about 77 degrees Fahrenheit. The product sprayed smoothly; no uneven build-up or runs. Excess material unnoticeably made its way to the bottom of the pickets and dripped off effortlessly. NOTE: Additional passes were needed for complete coverage because of the "fuzz" formed on the wood. The fuzz was created by pressure washing. The fence would have consumed less product and the application would have gone faster had an electric orbital sander been used on the pickets prior to sealing. A couple passes up and down with 120 grit sandpaper would have done the trick. It probably would have taken about 2 hours to sand the face of the pickets. After 35-40 minutes of filling, pumping and spraying, 5 gallons of sealer had been used. (6) 8' sections of fence were sealed and completed. That's 288 square foot of coverage. As mentioned above, more area would have been covered had the pickets been sanded. With coverage expectations in mind, (5) more 5 gallon buckets of sealer were purchased Saturday evening after work. These five cans were machine-shaken as well. The cans were stacked on the porch Saturday night to be used Sunday morning. Work began the next morning at 9:00am. The temperature was 62 degrees Fahrenheit, which was also the night-low. Filling the sprayer container, the sealer was thicker and poured more slowly than the bucket from the days earlier. When Spraying began, a huge problem was immediately encountered; uneven coverage, inconstancy, building-up and thickening. The product had to be evened out with a paint brush. Even after inconveniently brushing, the fence section still looked gooey. Thinking back on the negative reviews, the cans were searched for a production date; the batch number was located. The first can was 200xxx and the other cans were 130xxx-160xxx. A different Home Depot was contacted (store #4115) since all but 1 can were purchased from the first store. Unfortunately, all their stock was the lower batch number as well. The woman's name who gave assistance over the phone was Yvonne. She was extremely helpful, patient and determined to find a solution. It was agreed that contacting Thompson's on Monday was the best way to get accurate information on the batch numbers. Strapped for time and lack of work-days-off, another solution had to be found. "How can this stuff be thinned without ruining it"? The directions clearly state "do not thin". Then an epiphany!! The main ingredient is mineral oil. Oil gets thicker when cooled and thinner when heated. The directions mention the workable temperature is 50 degrees Fahrenheit and higher. That morning it was about 62 and rising. The cans were placed under the sun for about 2 hours. This brought the temperature above 70 degrees. The result was remarkable. The product once again flowed like water. The thick and gooey clear transformed into the beautiful workable product from days earlier. The fence was finished 3 hours following the increase in product temperature. There were 2 gallons leftover upon completion. The end result was beautiful, glowing natural-looking wood. This was very pleasing. So the issue is not with the mixture but with the operational temperature. The other folks who experienced a problem over the last few years most likely would have benefited from an increased temperature as well. The next day Thompson's was contacted and the findings were reported. The woman from Thompson's mentioned there was a formula alteration in 2013 which thickened the product. This was due to a change-in-requirements of the Environmental Protection Agency. She also mentioned there shouldn't be a significant difference in consistency between the different batch numbers. The negative reviews were brought to her attention as well. It was suggested to her the usage temperature be increased to 70 degrees Fahrenheit. Furthermore, the directions should state: if being applied with a pump sprayer, do not store container in an area where the temperature may decrease below 70 degrees. She mentioned she would immediately forward the information to the marketing department to address the concern. After speaking with Thompson's, Yvonne from The Home Depot was contacted. She was very happy to learn of the fix. Yvonne said she would educate her staff about the findings which would ultimately benefit the consumer. She represented her employer with utmost professionalism and sincerity; qualities not always found in today's corporate workforce. She is an asset to The Home Depot. Summery: *The product is excellent. It looks great and maintains a darker but natural wet look. *The price is wonderful compared to other marketed competitors. *The application is very easy when applied with a pump-sprayer. **If using a pump sprayer, be sure to store the can(s) in a room where the temperature remains above 70 degrees Fahrenheit or let the cans sit in the sun for 1-2 hours to increase the temperature. (Fall was 2 hours, the summer season may only need an hour). *If applying after pressure washing be sure to sand off the "fur" created by pressure washing. 120 grit sand paper with an electric orbital sander should work great. Otherwise, more product will be required to cover the desired area. Finally, enjoy! This product has just enhanced all your hard work.

We were pleasantly surprised how well our fence looked after a single coat of Thompson's WaterSeal. If it protects the fence as well as its looks now, we will wait and see, and update this review. But all indications are that it is a product that Thompson.s could proudly stand by. Thank you Thompson's and thank you Home Depot for a great product at a reasonable price. It met our expectation.

It left my deck blotchy with white stripes and white blotches. It is still tacky a week after application. I sprayed it on and the results are unacceptable. My can had a sticky label advising not to apply too thick. If you must use this poor product apply by hand and really thin. This stuff sits on top of the wood and does not penetrate dry wood like the previous product. I will not use again.
