Factors to Consider Before Choosing a Waterproofing Membrane
There are different types of waterproofing membranes. This includes fabric and liquid Ones. We will focus on these two types because they are the most popular types of the bunch. Fabric membranes are excellent products to waterproof your shower. They are usually applied on a coat thinset, and the set is transferred on the fabric. They are easy to install and are pliable. The liquid types, on the other hand, are versatile and have a wide range of applications. This includes wet places as well as the dry ones.
Ease of Application
Waterproofing membranes have varying ease of application. While some are relatively easy to apply, others are not. This is because some products peel right off and won’t stick to the thinset. As a result, there is partial waterproofing. Some fabrics have a unique texture that lets them stick better to the shower. Features like anchoring fleece or fleece webbing give such membrane stronger adhesion. For a liquid membrane, ease of application involves fast drying time and multiple application methods. Regardless of the type that you choose, ensure that it is easy to apply.
If the membrane cracks during use, it will ultimately affect the shower. Hence, we recommend that you look for membranes that are strong and tear-resistant. If you need to apply more than one coat, we suggest that you purchase a membrane that dries faster. This way, you can apply more coats at a faster pace.
