Types of Shower Waterproofing
Considering how severe water leakage can be, it’s good to ensure that your bathroom is watertight. But before you head to look for a shower waterproofing solution, you need to know the various types of waterproofing.

4. Traditional waterproofing
In this day and age, there are still some homeowners using this technique to waterproof their bathrooms. In the past, this approach involved the use of mud and some form of chicken wire to waterproof shower rooms.
Modern homeowners have replaced mud with advanced materials like cement board and fiber backer board. Unfortunately, this method isn’t very effective in protecting corners and horizontal surfaces.
How to Choose a Shower Waterproofing Membrane?
Knowing the different types of shower waterproofing solutions available is very useful. However, knowing that alone is not enough to help you make the right buying decision. Instead, you should consider the following factors as well;

Luckily, there are many membranes that have a convenient application process. Besides some even have a ready-to-use formula.
