Is Liquid Nails Waterproof? Understanding Its Water-Resistant Properties

When it comes to bonding materials, Liquid Nails has been a go-to adhesive for many DIY enthusiasts and professionals. With its impressive strength and versatility, it’s natural to wonder if this adhesive is also waterproof.

Continue reading to learn about the water-resistant properties of Liquid Nails and discuss their suitability for various applications.

Is Liquid Nails Waterproof?

Liquid Nails is water-resistant, meaning it can be used outdoors and will generally maintain a strong bond when exposed to elements like rain and snow. However, it is not 100% waterproof, so it should not be fully submerged in water for long periods of time.

Outdoor Applications

Due to its water-resistant properties, Liquid Nails can be used for various outdoor applications. For example, it can be utilized to bond wooden boards for constructing outdoor furniture, seal gaps in siding or trim, or secure tiles to an exterior surface.

In these situations, the adhesive should remain intact and functional even when exposed to occasional moisture.

Limitations with Prolonged Water Exposure

While Liquid Nails performs well in the face of moist conditions, it should not be mistaken as completely waterproof. Submerging the bonded materials in water for prolonged periods is not recommended, as the adhesive may eventually break down or weaken.

Therefore, it is important to ensure that prolonged water exposure is avoided to maintain the integrity of the bond.

How Long Before Liquid Nails Is Waterproof?

After applying Liquid Nails, it is important to allow enough time for it to dry. It starts to dry approximately 15 minutes after application, but it will take 24 hours for the drying process to complete.

During this time, it is not yet fully waterproof, so it is essential to avoid exposing the bonded surfaces to water until the drying process is finished.

Alternative Waterproofing Measures

In situations where absolute water resistance is required, complementing Liquid Nails with additional waterproofing measures is advisable. For example, applying a waterproof sealant over the bonded area can provide an extra layer of protection against water damage.

This combined approach can help ensure long-lasting performance, even in areas prone to high humidity or frequent water exposure.


Does Liquid Nails Seal Water?

Liquid Nails form a durable and waterproof bond even when used to bond two non-porous substrates. This means that it can provide effective sealing to prevent water from passing through easily.

Will Liquid Nails Dry in the Rain?

If you are using Liquid Nails for exterior applications, it is important to check the weather before starting the application process. It is recommended to choose moderate temperatures and ensure that there is no rain in the forecast for at least 3-5 days.

This will help create the ideal environment for the latex construction adhesive to dry and cure as expected.

Is Liquid Nails Construction Adhesive Waterproof?

Liquid Nails Construction Adhesive is not 100% waterproof. While it is water-resistant and can be used in exterior applications, it is not intended for continuous submersion or situations where it will be constantly exposed to water.

Is Liquid Nails Heavy Duty Waterproof?

Liquid Nails Heavy Duty is also not 100% waterproof. While it is designed for heavy-duty applications and can provide a strong bond, it is still vulnerable to water and should not be used in situations where continuous water exposure is expected1.

How Much Weight Can Liquid Nails Hold?

Liquid Nails is a strong adhesive and can hold a significant amount of weight. It is rated to hold up to 100 pounds.


Liquid Nails is a reliable adhesive with excellent water-resistant properties, making it suitable for a wide range of outdoor applications. Its ability to withstand exposure to rain and snow allows for reliable bonding in various situations. However, it is important to remember that Liquid Nails is not completely waterproof and should not be submerged in water for extended periods of time.

Remember, while Liquid Nails can add strength and durability to your projects, it’s crucial to assess specific requirements and consider alternative solutions for situations that demand absolute water resistance.
