A: Not at this time. The 1 gallon concentrate productis a different formulation and less concentrated then the SFSRC product. You would not get the right concentration of Spray & Forget to achieve optimal performance.
A: Yes! All Spray & Forget products work extremely well on all composite decking as both a cleaner and a preventative. Simply use a garden pump sprayer and follow the directions on the label as if your were applying to any exterior surface or use our new House & Deck product.
A: Using a garden pump sprayer, one gallon of Spray & Forget concentrate mixed 5 parts water to1 part Spray & Forget concentrate (5:1) will cover approximately 1000 Sq. Ft. and a mixture of 9:1 will cover approximately 2000 Sq. Ft. This is just an average coverage ratio based on using a garden pump sprayer and one gallon of Spray & Forget concentrated cleaner. Coverage can vary depending on the apparatus used to apply the product, the amount of concentrated product being used and the composition and inclination of the surface being treated. As a precaution, wet perimeter landscaping before and after you apply Spray & Forget as instructed on the label.
A: The super concentrate product will cover approximately 600 Sq. Ft. per unit and the 32 Ounce pre mixed product will cover approximately 100 Sq. Ft.
A: On average, Green stains will disappear in 1-3 days, black stains on non-roof surfaces will disappear in 1-8 weeks and roof stains will disappear in 30-180 days. The removal time is dependent on the amount of rainfall received, the severity of the staining, the concentration of the mixture used (5:1 to 9:1), and the type of stain.
A: Yes. Spray & Forget is very effective on roof moss. Simply apply a 5:1 to 9:1 mixture of Spray & Forget (5 parts water to 1 part cleaner or 9 parts water to 1 part cleaner) to the affected area and the moss will be completely removed with subsequent rainfall over the next 1-3 months, on average, or use our super concentrated roof cleaner with built in hose sprayer that mixes automatically and shoots up to 20 Feet. For thick moss applications, remove as much of the growth as possible first using the back end of a rake or broom and then apply spray & forget. This will expedite the removal process. Re-apply Spray & Forget every 18-36 months to prevent the stains from returning. Spray & Forget will not work to remove dirt, pollen, sap or soot.
A: Yes, Spray & Forget will work on almost any exterior surface and actually works faster on these surfaces then on roof surfaces. Apply 5 gallons of water to 1 gallon of Spray & Forget mixture to these surfaces. Green stains will disappear in 1-3 days and black stains in 1-8 weeks. Do not rinse! If you must have rapid results then you can rinse with a pressure washer using low to medium pressure. We do not recommend using a pressure washer unless you are an experienced user as they can cause damage to many surfaces.
A: Yes, you can paint/stain surfaces after applying Spray & Forget on them. If you are in a hurry, simply pressure wash the surface after applying the Spray & Forget to get it clean. There will be a small residual of Spray & Forget left behind that will continue to remove and prevent any stains caused by biological growth that can not be seen by the naked eye. You can then paint/stain/seal the surface after it dries. With that said, you do not have to pressure wash or rinse the surface. You can wait until the stains are removed with subsequent rainfall over time and then paint/stain/seal the surface when it is clean.
A: This is one of the unique advantages of Spray & Forget. Spray & Forget has a residual effect and actually adheres to the applied surface. In addition, Spray & Forget, unlike other cleaning methods such as pressure washing, will continue to clean long after the stains can not be seen by the naked eye. That means that the stains will be completely removed. For these reasons, we guarantee that roof stains will not reappear for at least two years and that stains on all other surfaces will remain clean for at least 12 months. Try getting that kind of result from pressure washing!
A: Spray & Forget is an excellent preventative! After the initial cleaning, use a mixture of 9 gallons of water to 1 gallon of Spray & Forget every 24-36 months on roofs and every 12-18 months on all other exterior surfaces. This will keep the stains from returning!
A: Unfortunately, you cannot use the hose end sprayer from your local hardware store. Those sprayers were not designed for Spray & Forget and do not draw at the right mix ratios for our product. They simply will not work. We recommend using a garden pump sprayer.
A: Sure! Our sprayer can be used with most other products since the mix ratio can be varied. However, always make sure to rinse the sprayer thoroughly before any application and consult with the chemical manufacturer of the product to be used before applying. Some pre dilution with water may be needed before using other chemical products. Consult the product manufacturer for instructions.
A: Unfortunately, Spray & Forget will not work on rust stains. You might try a product called wood bleach that contains Oxalic Acid and a small brush. Always consult with you local hardware store first and test on a small area.
A: Yes! Spray & Forget will work on all of these surfaces. Spray & Forget does not contain any harmful bleaching agents like chlorine or bleach and is not caustic like Sodium Hydroxide. However, you should always test a small area first to make sure that your specific stain is not affected. We have never had any problems with these surfaces but there are many types of stains and different building materials and grades of materials on the market. Therefore, you should always test a small area just to be safe. Spray & Forget will remove any black and/or green stains caused by algae and mildew. Spray & Forget will not return grayed wood to its original condition but will remove all black and green stains.
A: Yes, our product will immediately begin removing the root structure of the algae and/or moss stains which results in the surface becoming slippery. We recommend hiring a professional if you are not experienced with walking on roofs, heights or using a pressure washer.
A: Yes, for most shingles, you can rinse with a pressure washer but make sure that you use 500 PSI or less to prevent damaging the shingles and consult with us first if you are not sure if it is safe for your type of shingle. DO NOT USE HIGH PRESSURE ON YOUR ROOF! You can NOT use the injector on your pressure washer to apply Spray & Forget as it is meant for applying detergents only and will not get the right mix ratio.
A: Although we recommend using our “no rinse” application method since it is far safer, easier and less labor intensive, you can get rapid results using Spray & Forget. You would apply a 5 parts water to 1 part Spray & Forget concentrate mixture to the surface to be treated. Make sure that you apply to a dry surface with at least 24 hours before any heavy rainfall (check your weather forecast). Wait at least 12 hours after applying Spray & Forget and rinse with a pressure washer using low to medium pressure (~100-500 PSI).
A: We do not market Spray & Forget for indoor use. Therefore, we do not have any data to confirm or deny how Spray & Forget will work on indoor surfaces.
A: We do not have any data on using Spray & Forget in crawl spaces. Spray & Forget was designed to eliminate stains caused by biological growth but requires some pressure and/or brushing to actually remove the biological growth where the surface is not accessible to rain fall.
A: It is all right if you do not get rain for several weeks. In contrast, it is NOT all right if you get rain within 24 hours after applying Spray & Forget.
A: No, temperature does not affect Spray & Forget. However, you should apply it when the temperature is above freezing.
A: We recommend 5 parts water to 1 part Spray & Forget concentrate for all initial cleaning applications and 9 parts water to 1 part Spray & Forget concentrate for all preventive applications.
A: We do not recommend this! We have no data to support that this technique will expedite the removal process and it may have a negative impact.
A: Yes, Spray & Forget works very well on these surfaces. You will have to use the “no rinse” application as using any pressure on these surfaces may cause damage. For stubborn stains on highly textured surfaces, you may need to slightly brush the surface with a soft to medium bristled brush while the surface is still wet, after application, and then rinse with a garden hose or use a pressure washer with low to medium pressure.
A: No. As a caution, you should put pets inside while applying Spray & Forget and wait until the initial application is dry before returning them to the treated area. Run off after the initial application will not cause any harm to your pets.
A: Yes, Spray & Forget works very well on pool cages! Make sure that the pool filter is running when you apply the Spray & Forget and use a mixture of 9 parts water to 1 part S&F concentrate. Let the pool pump run for a few hours after the application. S&F will not harm your pool. You may want to check the PH of the pool a few hours after the application.
A: Spray & Forget was not designed to remove black vertical streaks (Referred to as Tiger Stripes) from light colored gutters. It will remove any green stains.
A: No. Artillery mold is extremely difficult to remove. Artillery mold creates a protective enamel shell around itself that is nearly impossible to penetrate. The best way to attack artillery mold is to prevent it from occurring. Most artillery mold is transferred to your home via some form of mulch. Make sure to test any mulch for artillery mold before putting it near your home.
A: Sure. Spray & Forget works well on these surfaces but can react with black staining on flat concrete surfaces which will result in that area turning a slight reddish/orange color for 24-48 hours. Do not be alarmed. The reddish/orange reaction will go away in 24-48 hours and confirms that Spray & Forget is working to remove the black staining from the flat concrete surface
