As a supplier of Watertite Waterproofing, I often get asked whether Watertite Waterproofing can be used on concrete. The short answer is yes, and in this blog post, I'll delve into the details of why and how you can effectively use Watertite Waterproofing on concrete surfaces.
Why Use Watertite Waterproofing on Concrete?
Concrete is a widely used construction material due to its strength, durability, and affordability. However, it is porous by nature, which means it can absorb water. This absorption can lead to a variety of problems over time, such as cracking, spalling, and the growth of mold and mildew. Waterproofing concrete is essential to protect its structural integrity and appearance.
Watertite Waterproofing offers several advantages when used on concrete:
- Excellent Water Resistance: Watertite forms a durable and flexible barrier that prevents water from penetrating the concrete. This is crucial for areas exposed to moisture, such as basements, foundations, and outdoor concrete structures.
- Long - lasting Protection: It provides long - term protection against water damage, reducing the need for frequent repairs and maintenance. This can save you both time and money in the long run.
- Versatility: Watertite can be used on different types of concrete surfaces, including new and old concrete. Whether it's a freshly poured driveway or an aged basement wall, Watertite can be applied effectively.
- Enhanced Durability: By preventing water ingress, Watertite helps to protect the concrete from freeze - thaw cycles, which can cause significant damage in colder climates.
How Watertite Waterproofing Works on Concrete
Watertite Waterproofing works through a combination of physical and chemical processes. When applied to a concrete surface, it penetrates the pores of the concrete. Once inside, it forms a hydrophobic (water - repelling) layer. This layer prevents water from entering the concrete while still allowing the concrete to breathe, which means that moisture vapor can escape from the concrete.
The chemical composition of Watertite is designed to react with the minerals in the concrete, creating a strong bond. This bond ensures that the waterproofing layer remains intact even under pressure and over time.
Preparation Before Applying Watertite on Concrete
Proper preparation is key to ensuring the effectiveness of Watertite Waterproofing on concrete. Here are the steps you should follow:
- Clean the Surface: Remove any dirt, debris, oil, or grease from the concrete surface. You can use a pressure washer, a stiff brush, and a suitable cleaning solution. Make sure the surface is completely dry before proceeding.
- Repair Cracks and Holes: Fill any cracks or holes in the concrete using a suitable concrete patching compound. Allow the patching material to dry and cure according to the manufacturer's instructions.
- Etch the Surface (Optional): For older or very smooth concrete surfaces, etching the surface can improve the adhesion of Watertite. You can use an acid - based etchant or a mechanical method, such as sandblasting.
Application of Watertite on Concrete
Once the surface is prepared, you can apply Watertite Waterproofing. Here are the general steps:
- Choose the Right Application Method: Watertite can be applied using a brush, roller, or sprayer. The choice of application method depends on the size and nature of the surface. For small areas or detailed work, a brush may be the best option. For larger areas, a roller or sprayer can save time.
- Apply the First Coat: Pour Watertite into a suitable container and start applying it to the concrete surface. Make sure to apply an even coat, covering the entire surface. Work in small sections to ensure proper coverage.
- Allow the First Coat to Dry: The drying time of the first coat depends on factors such as temperature, humidity, and the thickness of the coat. Generally, it takes a few hours to dry. Refer to the product label for specific drying times.
- Apply the Second Coat: After the first coat is dry, apply a second coat in the same manner as the first coat. The second coat provides additional protection and ensures a more complete waterproofing.
Areas Where Watertite Can Be Used on Concrete
- Basements: Basements are particularly vulnerable to water intrusion. Watertite can be applied to the interior or exterior walls and floors of basements to prevent water from seeping in. This helps to keep the basement dry and free from mold and mildew.
- Foundations: Protecting the foundation of a building is crucial for its structural stability. Watertite can be applied to the foundation walls to prevent water damage, which can lead to cracks and settlement.
- Driveways and Patios: Outdoor concrete surfaces like driveways and patios are exposed to the elements. Watertite can protect these surfaces from water, stains, and damage caused by vehicle traffic and foot traffic.
- Swimming Pools: Concrete swimming pools require effective waterproofing to prevent water leakage. Watertite can be used on the interior walls and floors of swimming pools to create a watertight seal.
Comparison with Other Waterproofing Options
There are other waterproofing options available for concrete, such as Best Waterproof Exterior Paint, Waterproofing Roof Paint, and Polymer Bitumen Membrane. While these options have their own advantages, Watertite offers some unique benefits.


- Best Waterproof Exterior Paint: Exterior paint can provide a decorative finish as well as some waterproofing. However, it may not penetrate the concrete as deeply as Watertite, and its durability may be limited over time.
- Waterproofing Roof Paint: Roof paint is designed for use on roofs and may not be as suitable for vertical concrete surfaces. Watertite, on the other hand, can be used on a variety of concrete surfaces, both horizontal and vertical.
- Polymer Bitumen Membrane: Membranes can provide a thick waterproofing layer but may require more complex installation. Watertite is easier to apply and can be a more cost - effective option for smaller projects.
Maintenance of Watertite - Treated Concrete
Once Watertite is applied to concrete, regular maintenance is still important. Here are some tips:
- Inspect Regularly: Check the waterproofed concrete surface periodically for any signs of damage or wear. Look for cracks, peeling, or areas where the waterproofing may have been compromised.
- Clean as Needed: Keep the surface clean to prevent the buildup of dirt and debris, which can reduce the effectiveness of the waterproofing.
- Reapply as Necessary: Over time, the waterproofing layer may wear off, especially in high - traffic or high - stress areas. If you notice a decrease in the waterproofing performance, you may need to reapply Watertite.
Conclusion
In conclusion, Watertite Waterproofing is an excellent choice for use on concrete. It offers effective, long - lasting, and versatile waterproofing solutions for a variety of concrete applications. Whether you're protecting a basement, a foundation, or an outdoor concrete structure, Watertite can help to keep your concrete dry and in good condition.
