In plumbing, irrigation, and other construction projects, PVC pipes and fittings are commonly used due to their durability, affordability, and ease of installation. Adhesives play an essential role in ensuring a solid and long-lasting joint.
There are distinct differences between PVC glue and cement, which are commonly used to bond PVC pipes and fittings. Throughout this article, I will compare PVC glue vs cement to assist you in choosing which one to use.

PVC Glue Vs. Cement
Overview of PVC Glue
PVC glue, or PVC adhesive, is a type of adhesive that is designed specifically for bonding PVC materials. It is usually packaged in a tube and applied to the PVC joint with a brush or applicator. The use of PVC glue is generally limited to small repairs or situations in which the joint will not be subject to a great deal of stress. After it has dried, it can be sanded or painted over.
The PVC glue binds the surfaces of the PVC pipes or fittings chemically. As a result, a strong bond is formed that is resistant to moisture, chemicals, and temperature changes. It is not recommended for joints that are under high stress or for projects requiring a watertight seal.
Overview of PVC Cement
PVC cement, which is also known as PVC solvent, is a type of solvent used to weld PVC pipes and fittings together. The PVC cement actually melts the plastic when it is applied to the joint, causing the two pieces to fuse together. In most cases, PVC cement is used in larger projects or in situations where there will be a great deal of stress on the joint.
It is commonly used in underground plumbing systems and is ideal for creating watertight seals. PVC cement creates a molecular bond between PVC pipes or fittings by dissolving the surfaces. With this process, you are able to create a lasting, water-resistant bond that is not affected by chemicals or temperature changes.

PVC Glue Vs. PVC Cement: What Is The Difference?
PVC glue and PVC cement are two types of adhesives used to bond PVC (polyvinyl chloride) pipes and fittings. Even though they are both designed for use with PVC materials, there are some key differences between them.
1. Chemical Composition
A PVC glue consists of a solvent-based adhesive, while PVC cement is a solvent that dissolves the surfaces of PVC pipes and fittings, forming a molecular bond between them.
2. Drying Time
The drying time of PVC glue is generally longer than that of PVC cement. It can take up to 24 hours for PVC glue to fully cure, as opposed to 15 minutes for PVC cement to fully cure.
The PVC glue dries clear and can be sanded or painted over, whereas the PVC cement leaves a visible joint.
When working on larger projects or joints that will be subjected to high stress, PVC cement creates a stronger bond than PVC glue.
5. Watertight Seal
For joints requiring a watertight seal, PVC cement is recommended, not PVC glue.

Is It Possible To Use PVC Cement As A Glue?
In spite of the fact that PVC cement is often called glue, it actually works in a very different manner. Two PVC parts are chemically bonded together by the substance. As a result of PVC cement, two PVC parts can never be separated.
Is PVC Glue Permanent?
PVC glue, also called PVC adhesive, bonds two PVC surfaces permanently. It is chemically bonded with PVC after the glue cures, creating a robust and durable bond that cannot be broken.
Both PVC glue and cement are effective adhesives for bonding PVC pipes and fittings, but they serve different purposes. For large projects and high-stress joints requiring a watertight seal, PVC cement is recommended, while PVC glue is ideal for small repairs and low-stress joints. Here, I compared PVC glue vs cement so that you can ensure a strong and long-lasting PVC joint by understanding the differences between them.
