I went out and bought 16 gallons of Thompson water seal. Went to go seal the fence with the pump sprayer,had it on fan spray and came out in a straight line. So, went and bought another sprayer that appeared to have a larger fan. Water came out fanned. Tried the water seal which is a bit thicker and again came out in a stream. Very upset wondering if I need to take the Thompson back as it will not fan out of my pump pressure sprayer. HELP

You need to learn how to use the sprayer.. I use back pack sprayer over 100 gallons on TWS and it's great.. doesn't clog like thicker products.

Instructions say not to apply over RECENTLY stained wood. How long is recently? 48 hours, 1 week, one month, or? Thanks.
Asked by: Steven
Hello, Time is dependent on if the current product has weathered or is still sealing the wood. To determine if the surface is able to accept a coat of our product, you will need to first test your surface by performing a "splash test." This will tell you if the surface is porous enough to properly absorb our products. The test is done by splashing some water on the wood. The water will do one of two things: 1.) Absorb into the surface making it slightly darker. This is a sign that our product will effectively absorb into the surface and you can apply our product successfully. 2. ) Water will puddle or just run off. This means that the surface is not very absorbent and our products will just form an oily, tacky layer on top. We would not recommend applying our products at this time. As long as the water test shows that the surface is absorbent, then you can proceed to perform a test area. This is important for two reasons -- it will help you learn how much product to apply before the surface is saturated and also show you what degree of discoloration will occur. As you will notice, once the surface has absorbed a certain amount of our product, then the remaining waterproofer just sits on the surface and can lead to oiliness, blotchiness, or discoloration. For this reason we recommend test areas to determine the porosity of the substrate and how much product you can apply in any given area. Regards, Thompson’s WaterSeal Customer Support

I have to used before to painting or after

Asked by: Poison
Hello. Paint after our product is applied. As long as the surface is clean and dry, you can paint over our oil based products with an oil based paint 7 days after application, or with a latex paint 45 days later. Regards, Thompson’s WaterSeal Customer Support

Rated 5 out of 5 by from Product being phased out This high-VOC, solvent-based formulation of Thompson's WaterSeal Waterproofer PLUS Clear Wood Protector is being replaced by a low-VOC formulation that may not be as easy to apply. If you want to use the high-VOC version of the product in the future, you may want to stock up now. The low-VOC formulation of Waterproofer PLUS Clear Wood Protector is currently being sold in cans that are virtually identical to the cans used for the high-VOC formulation, so you have to look for the VOC information on the side of the can to know which product you're buying. The high-VOC formulation will say "Maximum VOC: 600 g/L - 5 lb/gal," and the low-VOC formulation will say "Maximum VOC: 100 g/L (0.80 lb./gal)." Although high-VOC Waterproofer PLUS says it is for wood substrates only, I successfully applied it to a clean, new cinder block and got perfect beading in rain after it had dried for 48 hours. High-VOC Waterproofer PLUS did permanently darken the cinder block to a medium gray from a very light gray.

Rated 5 out of 5 by from Can't beat the price We wanted to buy the expensive stuff, but none of them got good reviews. We were also worried about how the tinted vs. clear would actually color the wood. So we decided to try the clear since the fence was brand new cedar. We used a $10 hand pump which worked wonderful. The Thompson's also went further than we expected, so we have a few 1-gallon cans left over. The 5-gallon gives a nice break in price, but is a little more difficult to pour and can be messy. The 1-gallons were a breeze. Make sure to cover any plants as they will turn yellow or black where there is overspray. Finally, we were very happy with the color. When the fence is in direct sun - you can't tell a difference. When its in indirect sun, the wood looks a bit darker - almost like it's wet, keeping that beautiful cedar color. I took a picture of a spot where I couldn't spray due to a large plant in the way. This was taken approx. two months after I applied the sealer.

Rated 5 out of 5 by from THE BEST PRODUCT AVAILABLE FOR PROTECTING A WOOD DECK I have a large exterior wood deck at my home, with the decking made of pressure treated pine. I have used Thompson's CLEAR Water Sealer for many years to protect this deck from wood deterioration (mildew/rot) and to keep it looking attractive and am 100% satisfied with this product. It is the BEST ONE in this class of products by various manufacturers. Be certain that you get the "CLEAR" version; which will let the natural grain of your wood show through and will enhance the look of that grain. To get an idea of what your wood will look like after it has been applied, just wet the wood with water and see how it then looks. When the Clear is applied it will look like this but CONSIDERABLY better than when it was just wet with water. After you've applied the CLEAR any water will just bead up on the surface of the wood, rather than being absorbed into the wood. A single coat of Thompsons will suffice and should last for about 2 years. I STRONGLY SUGGEST that before applying the Thompsons that you pressure clean the surface of the wood with a high pressure water machine capable of producing 3,500psi at the nozzle. That HIGH PRESSSURE cleaning will make your wood look LIKE NEW, regardless of how old that wood is. This step is as important as applying the Thompson's water seal. Let the now cleaned wood dry for at least 2 days and then apply Thompson's CLEAR Water Seal and you'll be amazed at what you're now looking at. It will look better than you can possibly imagine, usless you have actually done this before and have seen the results. It is well worth the effort. DON'T USE A SEALANT THAT HAS COLOR IN IT ! That's my last recommendation to you. Do the "CLEAR" FIRST. Only then, if you're not satisfied (I cannot imagine your not being satisfied) only then apply a colored sealant to your wood, which you can easily apply over the CLEAR.

Rated 4 out of 5 by from thompson waterseal I found it very easy to used and was a very good product. I think that the price was a little high but it did the job. I also found a rebate form from thompson's on line so it helped. thanks

Rated 5 out of 5 by from Product easy to use and does what it claims I used two 5 gal. containers to treat my deck and wood fence. I used a garden sprayer, which made application easy and quick. After a couple of rains, I can see the water beading up, which tells me the product is doing what it is supposed to do.

Rated 5 out of 5 by from Can't beat it I got it on sale for about $10 off. Easy to use with hand pump sprayer. Great spout for pouring. Covered just about what it says it will cover in square footage. Gives wood (yellow pine) a rich, golden brown look. Follow the instructions...apply one thin coat and water beads and pools up and does not penetrate the wood.

Rated 4 out of 5 by from First time using green labeled product, always used red label. Used pump up hand sprayer to apply on powerwashed deck wood about 20 years old. Job went smooth with cheapy $10 sprayer. Cleanup easy. Wood had been treated every 3 or 4 years with red label Thompsons. Wood developed nice somewhat darker shade after application. Will have to wait a couple of years for results and compare.
