will purple power hurt polyurethane sealants




Polyurethane sealants are widely used in various industries for their excellent sealing properties. However, when it comes to cleaning and maintenance, it is essential to choose the right product to avoid any damage. Purple Power is a popular cleaning solution known for its effectiveness in removing tough stains and grease. But, will Purple Power hurt polyurethane sealants? In this article, we will explore the potential impact of Purple Power on polyurethane sealants and provide guidelines on safe usage.

1. Understanding Polyurethane Sealants:

Polyurethane sealants are versatile adhesives commonly used in construction, automotive, and manufacturing industries. They provide excellent bonding and sealing properties, making them suitable for various applications. Polyurethane sealants offer exceptional durability, resistance to moisture, chemicals, and environmental factors, making them ideal for both indoor and outdoor use.

2. Introducing Purple Power:

Purple Power is a multipurpose cleaner and degreaser known for its strong cleaning capabilities. It is widely used in automotive, industrial, and household cleaning tasks. Purple Power effectively tackles grease, oil, dirt, and grime, making it a popular choice for cleaning engines, equipment, tools, and floors.

3. Potential Effects on Polyurethane Sealants:

Although Purple Power is effective for heavy-duty cleaning tasks, it can have adverse effects on some surfaces. When used improperly or on sensitive materials, Purple Power may cause damage. Polyurethane sealants, while robust, can be sensitive to certain chemicals, especially those containing solvents. Purple Power falls under this category and can potentially harm polyurethane sealants if used without caution.

4. Possible Reactions of Purple Power with Polyurethane Sealants:

When Purple Power comes into contact with polyurethane sealants, it can lead to various reactions depending on the duration and concentration of exposure. Some potential effects may include:

a) Swelling or Softening: Purple Power's solvents can dissolve the polymers in the sealant, causing swelling or softening of the material. This can negatively affect the sealant's adhesion and overall performance.

b) Discoloration: Purple Power's strong cleaning agents may alter the color of polyurethane sealants. This discoloration can impact the aesthetics of the sealed surface.

c) Loss of Elasticity: Prolonged exposure to Purple Power can compromise the elasticity of polyurethane sealants, leading to reduced flexibility and crack formation. This can affect the sealant's ability to accommodate movement and maintain an effective seal.

d) Weakening of Bond: Purple Power's solvents may cause the bond between the sealant and the substrate to weaken, leading to potential delamination or peeling.

5. Guidelines for Safe Usage:

To protect polyurethane sealants while using Purple Power, it is essential to follow a few guidelines:

a) Spot Test: Before using Purple Power on a polyurethane sealant, perform a spot test on an inconspicuous area. This will help determine if the sealant is compatible with the cleaner.

b) Dilute the Solution: Dilute Purple Power with water as recommended by the manufacturer. Using a heavily diluted solution can minimize the concentration of solvents that may harm polyurethane sealants.

c) Limit Exposure Time: When cleaning an area with polyurethane sealants, minimize the contact time between the sealant and Purple Power. Promptly rinse the surface with water after cleaning to remove any residue.

d) Protect Surrounding Areas: Cover adjacent surfaces or areas that don't require cleaning to prevent accidental contact with Purple Power.

e) Follow Manufacturer's Recommendations: Always adhere to the instructions provided by the polyurethane sealant and Purple Power manufacturers. They will offer specific guidance on cleaning and maintenance procedures.


When it comes to cleaning polyurethane sealants, caution should be exercised to avoid any potential damage. While Purple Power is an effective cleaner, it can have adverse effects on polyurethane sealants if not used properly. By following the guidelines mentioned above and understanding the potential reactions, you can safely utilize Purple Power while preserving the integrity and performance of your polyurethane sealants.
