Flex Shot – FAQs

Q: Why is there a black rubber plug on the bottom of my can of Flex Shot? 2019-04-10T17:10:27-05:00

A: Flex Shot is pressurized and the rubber plug on the bottom of the can is there to maintain the can’s pressure, and should not be removed. Removing the plug on the bottom will eliminate the can’s pressure which will result in the product not dispensing properly.

Q: How do I remove the Flex Shot extension tube? 2019-02-25T16:11:53-05:00

A: The extension tube screws on to the top of the Flex Shot can and is removed by unscrewing it in a counter clockwise direction. Do NOT attempt to remove the extension tube by pulling or yanking it off.

Q: How long will it take to receive my order? 2019-02-25T16:03:35-05:00

A: Most people receive their order within 2-6 business days after ordering. Though rare, some may experience slightly higher ship times, due to the location of the shipping address, or due to an item being temporarily out of stock.

Q: How do I change the thickness of the Flex Shot? 2019-02-25T16:06:50-05:00

A: To change the thickness, use Flex Shot with its extension tube. The extension tube can be cut to any size in order to produce the desired bead thickness.

Q: Are the extension tubes reusable? 2019-02-25T16:09:47-05:00

A: Yes, extension tubes are reusable. After using Flex Shot™ with the extension tube, you can leave the extension tube affixed to the can of Flex Shot™ and dispense just enough product to leave a 1/8” bead sticking out of the extension tube. The 1/8” bead will keep the remaining product in the can from drying out. Simply pull out the dry 1/8” bead prior to using Flex Shot™.

Q: Can I use Flex Shot™ to fill a really large hole? 2019-02-25T16:17:16-05:00

A: Yes, just follow these simple instructions:

1. Try to apply Flex Shot™ to the side of the hole that comes into direct contact with water (for example, if sealing a hole on a bucket of water, apply Flex Shot™ on the interior side of the bucket).
2. Place a backing (such as heavy paper or wire mesh) over the hole to be filled.
3. Fill the hole and the area surrounding the hole with Flex Shot™.
4. Once Flex Shot™ is dry, the hole will be sealed.

Q: Is Flex Shot™ mildew resistant? 2019-02-25T16:19:54-05:00

A: Yes! The white and almond Flex Shot™ contain a mildew fungicide, which will help to prevent mildew growth.

Q: Can I paint over Flex Shot? 2019-06-06T14:41:03-05:00

A: No, we do not recommend painting over Flex Shot. Since it repels liquid, it can also repel many common paints. However, Flex Shot comes in multiple colors to match almost any décor: white, almond and black. And then there’s always clear, which goes with anything and everything!

However, if you want to make any adjustments to the product, try to make these adjustments immediately after the product is applied, before it starts to dry. Remove any excess Flex Shot™ immediately, with a dry paper towel.

Q: How do I use Flex Shot? 2019-02-25T16:41:33-05:00

Flex Shot™ is so easy to use! Just follow these simple steps:

  1. All surfaces must be clean, dry and free from dirt, grease and oil.
  2. Hold can at a 45-degree angle, push against the nozzle and apply directly to the area to be treated. For a perfect bead, apply in a steady, even motion. Adjust your speed to control the thickness of the bead.
  3. If further tooling is required, complete within 5 minutes. Remove excess sealant immediately with a dry paper towel.
  4. After using, extend a small amount of material beyond the end of the nozzle. This will cure and form a seal for the remaining material. Pull out this cured plug when you are ready to use again.
