    Q: Can this be used to seal around a heating pipe, or can you recommend something else?

    A: Yes. It expands to fill holes, cracks, gaps and voids around windows, doors, pipes, outlets, vents.
    Q: Can the mouse holes on the wall be filled? Is it sturdy?
    A: Yes, our product has the effect of preventing insects and mice. After drying, it becomes very hard and mice cannot chew through it.
    Q: Does it have any odor? Are the materials safe?
    A: We use environmentally friendly materials that are safe, non-toxic, and odorless.
    Q: How long can the product be stored? How should it be stored?
    A: Our products have a good shelf life, and unopened items can be stored for up to one year. But due to the nature of the clay, we recommend using the product or storing it in a sealed bag as soon as it's been opened (it can be stored for up to six months under normal conditions).
    Q: How long will it stay tacky? How do I remove it?
    A: Our products have a good sealing capability and can remain hard for 1-2 years after air drying. If removal is necessary, you can use a hammer to break and remove it.
    Q: How many packs of Sealant Mastic are needed to fill a hole in an air conditioning vent?
    A: Usually, it takes about 2-3 packs of Sealant Mastic for a typical air conditioning vent hole (for reference only, it depends on the specific hole size). Our product has versatile applications, so we recommend taking advantage of the promotional period and purchasing multiple packs.
