Is Contact Cement Waterproof

One important question that often arises is whether contact cement is waterproof or not. In this article, we will delve into the waterproof properties of contact cement, and explore the factors that affect its waterproofness. We will also provide best practices for achieving waterproof results with contact cement and answer some frequently asked questions.

Let’s dive into this peculiar topic and uncover the taste, health risks, and even unique uses of glue beyond its intended purpose.

Convert to active voice: Industries use contact cement (contact adhesive) commonly in construction, woodworking, and manufacturing. It forms a strong, permanent bond when applied to two surfaces and pressed together. The adhesive properties of contact cement make it ideal for use in a wide range of applications, including laminating, flooring, and furniture making.

Contact cement is a type of adhesive that is made from a combination of resins, solvents, and fillers. The resins provide the adhesive properties, while the solvents make the cement flow easily for easy application. Fillers are added to improve the strength and durability of the adhesive.

There are two types of contact cement, solvent-based and water-based. Industries traditionally use solvent-based contact cement (made with petroleum-based solvents). Water-based contact cement is an eco-friendlier alternative that uses water as the primary solvent.

Popular brands of contact cement include 3M Super 77, Titebond III Ultimate Wood Glue, and Gorilla Super Glue. People commonly use contact cement to laminate countertops, install carpet, and bond veneers to furniture.

Waterproofness Properties Of Contact Cement

Waterproofness is the ability to resist water penetration without damage. To evaluate contact cement’s waterproof properties, consider the application type, surface, and environment

Contact cement is water-resistant and can withstand some water exposure without losing its bond. Contact cement isn’t waterproof and may not be suitable for highly moist or watery applications.

Compared to other adhesives, such as epoxy or polyurethane, contact cement is not as waterproof. For critical water-resistant applications like marine and industrial, people use expensive and longer-curing adhesives with superior waterproof properties.

Contact cement has been successfully used in water-resistant projects like laminated countertops, flooring, and furniture. Surface prep, quality products, and proper application techniques are essential for optimal results with contact cement.

Factors That Affect the Waterproofness of Contact Cement

There are several factors that can affect the waterproofness of contact cement, including environmental factors, surface preparation, application techniques, product quality, and maintenance and upkeep.

Environmental factors, such as temperature and humidity, can impact the cure time and strength of the bond. If the surfaces are not properly prepared, the bond may not be as strong and may be more susceptible to moisture. Improper application techniques, such as not allowing the cement to cure completely or applying too much pressure, can also weaken the bond and increase the risk of water damage.

The quality of the product is also important. Low-quality contact cement may not be as waterproof and may break high-quality, reputable brands of contact cement for the best results and to ensure waterproofness.

Maintenance and upkeep also play a role in the waterproofness of contact cement. Properly cleaning and sealing the surface can help protect the bond from water damage and extend its lifespan. Regular inspections and maintenance can also help identify and address any issues before they become serious problems.

Best Practices for Achieving Waterproof Results with Contact Cement

To achieve the best waterproof results with contact cement, it is important to follow best practices for preparation, application, and maintenance.

  • Surface preparation: Clean and dry the surfaces to be bonded and remove any dirt, dust, or other contaminants. This will ensure a strong, permanent bond.
  • Application techniques: Follow the manufacturer’s recommended application techniques and allow sufficient time for the cement to cure completely before exposing it to water.
  • Product quality: Use high-quality, reputable brands of contact cement and choose the right type of contact cement for your application (solvent-based or water-based).
  • Maintenance and upkeep: Regularly inspect and maintain the bond to ensure it remains strong and waterproof. Proper cleaning and sealing can also help protect the bond from water damage.


The question that often arises among professionals and enthusiasts who use contact cement is Is contact cement waterproof? While cement is not completely waterproof, it is water-resistant and can withstand some exposure to water without losing its bond. However, achieving waterproof results with contact cement depends on several factors, such as environmental conditions, surface preparation, application techniques, product quality, and maintenance. Following best practices, using high-quality products, and maintaining the bond can help ensure its water-resistant properties. So, while contact cement is not entirely waterproof, it can be used in applications where water resistance is important with proper preparation and application techniques.

Contact cement is water-resistant, but it is not completely waterproof. Contact cement resists some water exposure without losing its bond, but isn’t suitable for highly moist or watery applications.

Compared to other adhesives, such as epoxy or polyurethane, contact cement is not as waterproof. These adhesives offer superior waterproof properties, but they are typically more expensive and have a longer cure time.

It is not recommended to use contact cement in marine applications that will be exposed to high levels of moisture or water. Other adhesives, such as epoxy or polyurethane, offer better waterproof properties for these types of applications.

Yes, contact cement can be used for flooring, but it is important to properly prepare the surfaces, use high-quality products, and follow recommended application techniques to ensure the best results.
