Understanding Waterproofing

Waterproofing is a critical step in any construction or renovation project, especially in areas prone to moisture, like bathrooms. Let’s take a closer look at the two main contenders: hot mop and Schluter.

What is Hot Mop?

Hot mop, also known as hot tar, is a traditional waterproofing method involving the application of layers of hot asphalt to create a waterproof barrier. This method has been used for decades and is known for its effectiveness.

What is Schluter?

On the other hand, Schluter systems involve the use of a membrane that provides a waterproof barrier beneath the tile or stone surface. Schluter has gained popularity for its modern approach to waterproofing.

Pros and Cons of Hot Mop

Benefits of Hot Mop

Hot mop offers excellent waterproofing, making it a reliable choice for bathrooms. Its longevity and durability are well-regarded, providing a robust solution against moisture.

Drawbacks of Hot Mop

However, hot mop comes with its challenges. The installation process can be labor-intensive, and the materials used may have environmental concerns. Additionally, hot mop may have limitations in design flexibility.

Pros and Cons of Schluter

Advantages of Schluter
