Steps to Protecting Bathroom from Leakage with Waterproofing

Making bathroom floors resistant to damage from water and moisture is very important in any construction project. To safeguard the appearance and strength of houses and buildings, it is crucial to protect bathrooms from the deteriorating effects of water.

Below are the steps to protecting bathroom from leakage with waterproofing chemicals –

1. Preparing for waterproofing

The first step in protecting bathroom from leakage with waterproofing chemicals is to prepare the surface with insulation. This involves removing the existing flooring and ensuring that the substrate surface underneath is dry, clean and does not have any debris that can affect uniform application of concrete waterproofing additive.

2. Choosing suitable waterproofing additive

Once the bathroom floor is insulated and prepared, it is time to select the appropriate waterproofing chemical according to the specific construction needs.

There are a variety of waterproofing compounds available for use in the construction industry, where each has its own advantages and application methods. Hence, it is necessary to buy a waterproofing additive that suits the specific needs of your construction design.

3. Applying primer

The next step involves applying primer and preparing the surface with proper adhesion so the waterproofing material can be applied evenly. The primer forms a strong bond between the waterproofing layer and the flooring substrate which makes it more effective.

It is advised to follow the manufacturer’s instructions when applying the primer. Make sure to let the primer dry completely before moving to the next step.

4. Sealing joints

Next, you will need to cover the vulnerable joints between the floor and walls which are likely to let water seep under the tiles. It is recommended to use a waterproof sealant to cover these joints completely. Also make sure to cover all corners and especially the areas around pipes and drains, as they are more prone to water seepage.

5. Test the sealant

The final step after applying the waterproofing chemicals on bathroom floors is to test their effectiveness. To do this, you can simply pour a small bucket of water on the treated floor and let it settle for a few minutes. This makes it easier to detect signs of leakage or seepage on the surface.

If you find evidence of water leakage, you should make the required repairs before covering the floor again with tiles or other flooring material.

How to Waterproof Bathroom Walls?

Making the walls of a bathroom waterproof is as important as the floors. Water from baths and showers splashes frequently against the bathroom walls and can often seep inside. This can cause the growth of mold and mildew, and result in peeling paint and can even lead to structural damage.

Below are the simple steps to waterproof bathrooms walls using concrete waterproof additives –

1. Choose waterproofing material

Unlike for bathroom floors, the first step in making bathroom walls waterproof is to choose the right wall waterproofing chemical. This is vital to get the best results.

Construction experts recommend buying waterproof membranes to make bathroom walls resistant to water damage. These construction compounds prevent water from seeping inside the wall tiles. Make sure to choose a waterproofing additive that suits the type of wall surface of your bathroom.

2. Prepare with primer

The next step in waterproofing bathroom walls is to prepare the surface with a primer. Primer helps to improve the adhesion between the wall surface and the waterproofing material, which enhances its functions. To do this, you should clean the walls completely, as well as repair any holes or cracks and then apply the primer.

3. Apply waterproofing paint

The third step is to apply the waterproof paint evenly over the surface of the bathroom walls, ensuring the waterproof membrane covers it completely. The waterproofing chemical becomes a secondary protection against water damage and gives the walls extra protection.

For the best outcome, you should buy high-quality waterproofing chemicals, such as Addage WPC Liquid by Sakshi Chem Sciences.

4. Testing

Testing the effectiveness of the waterproofing chemicals is as important as applying it correctly. Once you finish applying the waterproofing material over the bathroom wall let it dry before spraying water on it.

If there are any leaks or seepage, you will be able to identify the trouble spots easily. Make sure to observe the joints, corners, edges and areas around bathroom fixtures as these are the most vulnerable to water-damage.

If you see any leaks or seepage, then make the necessary repairs as soon as possible and then test them again for effectiveness.


Protecting bathroom from leakage with waterproofing chemicals is an important decision to protect your home’s aesthetics and structural integrity. This process helps to safeguard not just the home but also promotes hygienic home environment and preserves the market value of your house.

By using the right concrete waterproofing additive, you can successfully ensure that the walls and floors of the bathrooms in your home are protected against damage from water and the house is safeguarded against damage to the structure and its appearance.
