HOW TO INSTALL PERMASHIELD® TIRE SEALANT
This guide is provided for all field technicians installing the Permashield Tire Sealant product into new or used automobile tires. It is designed to provide detailed installation instruction, thereby minimizing errors which may otherwise occur during installation. Proper installation will ensure customer satisfaction and compliance with tire manufacturer warranty specifications. We are here to assist. Should any questions arise regarding the installation procedure and you cannot find the answers in the manual, please do not hesitate to contact us or contact your representative for assistance.
Equipment / Personnel needed for installation
- Permashield supplied 5 or 6 gallon container of product and calibrated installation pump or syringe, 55 gallon drum and pump, or combination thereof.
- Certified Permashield Tire Sealant Installer.
- Compressed (dry) air / Nitrogen optional (if your dealership/service center offers this service it is highly recommended to be installed with the sealant product for optimal results).
- Accurate air pressure gauge
- Access to online or printed dosage calculator
- Valve stem removal tool
- Dual wheel application valve extensions
- EM (earth moving) valve reducer (for earth moving type equipment)
- Safety glasses
- Rags and water for clean up if required
*ALL INSTALLATIONS SHOULD BE DONE IN A PROPER, SAFE, AND PROFESSIONALLY EQUIPPED SERVICE AREA.
- Prior to installing, you will need to calculate the amount of product that will be inserted into the tire. This very important step will ensure that you achieve adequate protection for the tire. Installing too little product will not adequately cover the required area inside of the tire and protect it from punctures. Alternatively, too much product installed within the tire will potentially cause imbalance issues. Click here for the light duty dosage calculator or here for the heavy duty dosage calculator.
- Tires should be checked prior to installation for balance and possible contamination. Water, dirt or other material will affect negatively the performance of the sealant. If there are existing balance issues with the wheels and tires (such as feathering or uneven wear of the tires), we highly recommend correction of these problems prior to installation. Failure to correct these problems may result in uneven distribution of the sealant inside the tire, thereby limiting the effectiveness of the product and potentially causing a vibration in the ride on the tires. For low speed tires (less than 30 mph), dosage may be increased approximately 10-20% to cover sidewall area of tires. Please speak with our technical team for dosage advice on these installations.
- Wheels and tires on most automobiles do not have to be removed for proper installation. If installing in a dual wheel setup, we recommend removal of the outside wheel for ease of access and to ensure proper insertion. Rotate each wheel so the valve stem is between the 10:00 and 2:00 position.
- Remove the valve stem core from each tire prior to attaching the calibrated installation pump or syringe. The tire does not have to be completely deflated prior to installation, but it is helpful to have as little air pressure as possible in the tire. Recommendation is less than 20psi, although the installation pumps are rated for working at up to 60 psi. IMPORTANT –the pump system provided has a calibrated stroke equivalent up to 8 oz. A stroke is measured from the handle fully being extended and then completely depressed. For example, if you need to install 24 oz, this would equal 3 strokes per tire. For dosages needing increments less than the full 8 oz per stroke, adjust the dosage clamp on the calibrated pump shaft to the appropriate ounces per stroke. If using a syringe, you will simply fill to the appropriate volume level as indicated on the syringe body. If you have any questions or concerns about dosage or installation of the product, please contact your sales representative or our support staff.
- Once the installation pump is connected to the valve stem on the tire, slowly pump one stroke from the container and make sure the sealant flows smoothly into the tire. If using a syringe, slowly depress the plunger and make sure sealant flows smoothly into the tire. If there is no issue, proceed to fill the tire with the appropriate amount per the dosage chart and continue the installation on the remaining tires. If the product does not flow into the valve smoothly, you will know immediately. Do not try to force the sealant into the tire. It is actually “sealing” the valve opening inadvertently. In this case you can typically use an air hose and blow directly into the valve stem, freeing up the blockage. One alternative method of installation on a new or dismounted tire would be to simply pump the required dosage directly into the inside of the tire prior to mounting. It is important to note that the sealant should be evenly spread inside the tire prior to balancing. This is a very rare occurrence; however there may be some valves which do not accommodate the normal installation procedure. Any spill or leakage of the product may be simply wiped clean with a shop rag and water.
- Once the sealant is fully injected in the tire, insert the valve core and re-inflate to the manufacturer recommended pressure with ambient air or Nitrogen. Note: It is important to make sure you have clean, dry air going into the tire, as water from an unfiltered air compressor can adversely affect the product in the tire and cause balance issues.
- After installing in the tires, you must drive the vehicle to evenly distribute the sealant inside the tread area of the tire and “activate” the protection. We recommend beginning this activation period as soon as possible after installation. Typically, activation requires that the vehicle be driven at safe speeds above 50 mph for at least 5 miles so the product can evenly distribute and coat inside of the tires. On passenger vehicles, you will feel a vibration or imbalance of the tires on the initial portion of the drive, and then feel it go away a become smooth. Once it smooths out, the product is activated. Heavier vehicles may not experience this vibration. This is normal, but activation still requires driving it above 50mph for 3-6 miles.
Removing Product from Tire
If for any reason you require the tire sealant to be removed from the tires, such as in the case of re-treading a truck tire, the process is very simple. Permashield Tire Sealant is non-toxic, non-combustible, water soluble, and easily cleaned up. Removal from a tire will have no adverse effect on the tire itself. If you have any questions or concerns about removing any Permashield Tire Sealant products, please contact us and we will have a support representative assist you with the procedure for proper removal of the product.
Recommended removal procedure:
- Properly remove the wheel and tire from vehicle.
- Dismount tires from wheels using a qualified wheel and tire machine.
- You will find a thin film of sealant spread on the inside of the tread area of the tire. Using a high powered wet/dry shop vacuum you can remove the product by vacuuming the product directly out of the tire. Alternatively, you can use a plastic scraping tool to scrape out the sealant and dispose in a bucket or bag.
- Once the majority of the sealant has been removed using a vacuum or scraper, finish removing the remaining film using warm water and a sponge or a hose. Permashield Tire Sealant is water soluble and will break down for easy removal.
- Wipe tires out with a clean, dry rag. Also, remove any residue that may be on the wheel. Although we recommend gloves and eye protection, the product should cause no adverse reactions to skin or clothing and simply washes off with hot water and soap.
- Once clean and dry, the tire is ready to be mounted and balanced on the wheel, and then re-installed on the vehicle. Keep in mind, Permashield is non-toxic, biodegradable, and will dry out completely when exposed to the open atmosphere.
