Clear the balcony of any furniture, debris, or plants. This will help you get a better idea of the condition of your balcony floor and allow you to work more efficiently.
Step 2. Inspect for Cracks
Look for any cracks or damages on your balcony floor. These should be repaired before proceeding with waterproofing to ensure a smooth and long-lasting finish.
Use a suitable filler or sealant to fix any cracks, holes, or damages on your balcony floor. Make sure to follow the instructions on the product and allow enough time for it to dry completely.
Step 3. Clean the Surface
Thoroughly clean the surface of your balcony floor using a pressure washer or a high-quality cleaner. This will remove any dirt, grime, or stains and ensure better adhesion for the waterproofing material.
There are various options available for balcony floor waterproofing such as liquid membrane, sheet membrane, or cementitious coating.
Consider factors like durability, cost, and application method before making a decision.
Step 4. Prepare the Waterproofing Material
Follow the instructions provided by the manufacturer to properly prepare the chosen waterproofing material. This may involve mixing, diluting, or heating before application.
In some cases, it is recommended to apply a primer before applying the waterproofing material. This will provide better adhesion and ensure a more effective seal.
Step 5. Start Applying Waterproofing Material
Using a brush, roller, or sprayer, start applying the waterproofing material evenly on your balcony floor. Make sure to cover all areas and follow the recommended number of coats for best results.
Follow the manufacturer’s instructions for drying time between coats and before walking or placing any furniture on the balcony floor. This will ensure that the waterproofing material has been properly cured.

Tips for How to Waterproof Balcony Floor
- One of the best ways to ensure a waterproof balcony floor is to regularly inspect it for any damages. Look out for cracks, holes, or any other signs of wear and tear. If you spot any issues, make sure to fix them immediately before they worsen.
- When choosing materials for your balcony floor, opt for waterproof and durable options such as concrete, ceramic tiles, or vinyl flooring. These materials are less prone to water damage and can withstand heavy foot traffic.
- Make sure to properly slope your balcony floor towards the drain or gutter to prevent water from pooling on the surface. This will also help with proper drainage and prevents water from seeping into the floor.
- Regularly clean and maintain your balcony floor to prevent the buildup of dirt, debris, or standing water. This not only ensures a waterproof surface but also prevents slips and falls.
- Consider adding a protective sealing layer on top of your balcony floor for added protection against water damage. This can be done by applying a waterproof sealant or coating specifically designed for outdoor surfaces.
- If your balcony is located above a living space, make sure to install a waterproof membrane underneath the floor to prevent any water or moisture from seeping through and causing damage to the ceiling below.
- Lastly, always be cautious when using any cleaning products on your balcony floor as some chemicals can cause damage to waterproof materials.
What Are the Most Cost-effective Methods for Waterproofing a Balcony Floor?
Waterproofing a balcony floor is essential to prevent water damage and keep the structure of your building safe.
It is especially important if the balcony is located above living spaces, as any water leaks can cause significant damage and lead to costly repairs.
There are various methods for waterproofing a balcony floor, but some are more cost-effective than others.
In this article, we will discuss the most cost-effective methods for waterproofing a balcony floor.
1. Liquid Waterproofing Membrane
Liquid waterproofing membrane is a popular and cost-effective method for waterproofing a balcony floor.
It is applied as a liquid coating that cures into a flexible rubber-like membrane, creating a seamless barrier against water penetration.
This method is relatively easy to install and can be applied on various types of surfaces, such as concrete, tiles, and wood.
It is also a durable option, with an average lifespan of 10-15 years.
2. Sheet Membrane Waterproofing
Sheet membrane waterproofing is another cost-effective method that involves installing a sheet of waterproof material over the balcony floor.
The sheets are made from materials like bitumen, rubber, or PVC and are typically applied in layers for added protection.
This method provides a strong barrier against water intrusion and can last up to 20 years with proper maintenance.
However, it requires professional installation and may not be suitable for all types of surfaces.
3. Cementitious Waterproofing
Cementitious waterproofing is a traditional method that involves applying a cement-based mixture to the balcony floor.
This mixture contains special additives that make it waterproof, creating a strong and durable barrier against water.
This method is cost-effective and can be applied on various surfaces, but it requires multiple layers and must be installed by experienced professionals for maximum effectiveness.
4. Polyurethane Liquid Membrane
Polyurethane liquid membrane is another popular method for waterproofing a balcony floor. It is similar to the liquid waterproofing membrane, but it creates a thicker and more durable barrier against water.
This method is easy to install and can be applied on both horizontal and vertical surfaces. It also has a longer lifespan of 15-20 years, making it a cost-effective option in the long run.
What Are the Potential Risks Associated With Waterproofing a Balcony Floor?

1. Damage to the Structure
Waterproofing materials can be harsh and may cause damage to the structure of your balcony floor if not applied properly or if the wrong type of material is used.
2. Trapping Moisture
If waterproofing is not done correctly, it can trap moisture within the balcony floor which can lead to mold and mildew growth. This can also cause damage to the flooring materials and create an unhealthy living environment.
3. Improper Drainage
Waterproofing a balcony floor may also affect the drainage system of your building if not done correctly. This can lead to water accumulation and potential flooding, causing damage to your property.
4. Chemical Exposure
Some waterproofing materials contain harsh chemicals that can be harmful to humans and the environment. These chemicals may emit strong odors and fumes during application, requiring proper ventilation and safety precautions.
5. Costly Repairs
If improperly applied or if the wrong materials are used, waterproofing a balcony floor can lead to costly repairs in the future. This is why it’s important to hire a professional and use high-quality materials.
It’s crucial to weigh these risks against the benefits of waterproofing before making a decision.
In most cases, hiring a reputable professional with experience in waterproofing is highly recommended to ensure proper application and minimize potential risks.
