We recommend waiting for the growth to come off the surface completely, then painting the surface. That way the dead growth won't become sealed into the surface.

is it safe with cistern or cover gutter

Asked by Pete June 5, 2020
5
Answers

When using Wet & Forget on your roof that has a cistern, please follow these instructions: 1.) Disconnect the water supply to your cistern for at least 5 weeks after applying Wet & Forget to avoid any chance of contamination. 2.) Be sure that you have several rainfalls over the "stand down" period to wash the Wet & Forget from the surface. 3.) Check before reconnecting that the water flowing onto the ground, when it is not raining, is NOT foaming.

How can I reach my roof on a two story house with this product? A pump sprayer won't reach.

Asked by Coach May 11, 2020

Answers

Hi, Coach; I guess with a big house you might need an extra boost of power, but we have a split level and our pump was adequate... There are power sprayers available, like this one you can wear from HD; https://www.homedepot.com/p/Scotts-4-Gal-No-Leak-Professional-Backpack-Sprayer-190540/303588180. I hope this will be a good alternative. Good luck with your roof, I think you'll be pleased with this product!

I have a cottage in a densely treed area and had a lot of moss on my roof. Since using this product over the last several years I have had no moss problem and the roof appears like new. I recommend this to everyone in our area.

Hi Guy! Wet & Forget works with the rain and wind to gently clean up green and black stains on your patio. You won't see instant results. Black stains are a bit stubborn, and can take a month or two for you to start to see a change. We'd like to learn a little more about your application, if you could please give our office a call at 888-727-8524 so we can help you out. WetandForget

I live in Florida which has a high probability of hurricane hits so I have a metal roof which will withstand high winds. Unfortunately, part of my roof is under oak trees and the shade causes green algae to grow. I have used other algae removers that have to be rinsed off and can damage plants. This product requires no rinsing and does not harm plants. Just use a pump up sprayer and spray the problem areas. In a few days all of the green stuff and mildew was gone and my roof is nice and shiny. Another plus is the low price as this one gallon container of concentrate makes six gallons of remover. The remover was such a great buy that I bought more than I needed for future use. It was shipped right to my home at no extra charge. How do you beat that! Try it and I think you will be happy with this product as well.

In the past, I used my hand blower to remove clumps of moss, but I waited too long this time and the growth is out of control. After doing some research, I selected Wet & Forget (had to order online from Home Depot for pick-up from store) since it had a fair number of positive reviews and it was a MILD remover regarding surrounding plants and animals. Directions call to mix it 1 gal. of solution to 6 gallons of water, apply on an overcast day to avoid rapid evaporation and when rain was not expected for several hours. The image shows the results AFTER LESS THAN 48 HOURS: the moss clump on left was treated and the moss on right was a clump I had removed without treatment and then used for comparison. The Wet and Forget looks very effective so far! Looking ahead, once the moss dies off and I can blow the dead vegetation away, I am going to attach a zinc strip to the ridge vent for long term, continuous treatment. I will continue to use Wet & Forget for touchup as needed.

Two stars because it was easy to mix and apply BUT It's been over 2 weeks and I see absolutely no change. I used it on my wood deck, vinyl siding, brick steps and patio blocks. We've had a lot of rain which I thought was supposed to wash away the mold, mildew, etc. but it's all still there. Very disappointed. $32 for the product, $15 for the sprayer and nothing to show for it. :(

You most likely will not see changes on black stains after two weeks. Black stains and moss clean up after a few months. Green stains will clean up after two weeks with good rain. Please give our office a call at 888-727-8524 so we can look into this and help you out. WetandForget

This product is easy to use... as the name implies. . Just wet and forget. It does take some time to work . If you are looking for an immediate result than this product is not for you. It is easy to use and inexpensive enough to reapply often and take control of moss and algae growth on many different surfaces.. concert...wood... roof shingles ect.. I like it .. and would recommend it. Wish you could just walk Into a home depot and buy it.. ordering on line was ok.. but i would rather just go get it when I need it.

I use this product on family headstones that have been covered with moss and mold. It works brilliantly ! It slowly removes the moss and mold build up with no scrubbing or wiping. Just spray it on and mother nature does the rest.

What they did forget to tell you is that it absolutely DOES NOT work. Bought a 1/2 gallon and did a test on my my standard fiberglass shingles. A 100 sq ft area did absolutely nothing. Right next to it I did another test of bleach water and scrubbing with a broom - which worked well - but was certainly work. Don't waste your money and anxiety for a product that's a waste. Only thing that works on algae/mildew/moss stained roof is scrubbing with bleach water.

After a day or two, green algae will die off and have a grayish color. After a nice rain, you shouldn't see any remains. Please give our office a call at 888-727-8524 for more assistance. WetandForget

I have used Wet & Forget for several years to address Mildew & Algae related growths on buildings as I live in a heavily wooded area which means I'm always cleaning something, so Wet & Forget saves me from having to break out the power washer & spend half of a day washing the house. Like the name says, I just Wet & Forget, then a few days later you can see the difference. I was super impressed, when I used Wet & Forget to clean 43 years worth of weathering from a family tomb, this product restored the concrete to a like new condition, it did take 2 applications, but saved me so much time & effort. Whenever I see folks struggling with Mold, Mildew & Algae issues, I recommend they use Wet & Forget and I know I have converted others to fans of the product, because I see them using it and they too comment on how easy it is. The attached images are taken 2 days apart and demonstrate how simple and fast the product works for me.
