Features of waterproof material Sika MonoTop® 166
Sika MonoTop® 166 is a liquid product, based on cement and polymer, used in the repair and protection of concrete surfaces. This product is often used to repair cracks, holes, or damage in concrete surfaces, while providing waterproofing and surface protection against environmental influences. Here are some common uses of Sika MonoTop® 166:
1. Repair of cracks and holes in concrete surfaces
Sika MonoTop® 166 is used to repair cracks and gouges in concrete surfaces, helping to restore the aesthetics and functionality of the surface.
2. Concrete Surface Protection
This product has the ability to create a protective film on the concrete surface, helping to resist the effects of weather, chemical environment, and other harmful factors.
3. Waterproofing
Sika MonoTop® 166 has the ability to form a waterproof layer, which helps prevent the penetration of water, liquid and vapor into the concrete surface.
4. Enhanced Adhesion
This product provides enhanced adhesion between the repair film and the base concrete surface, creating a strong and durable bond.
5. Improved mechanical performance
Sika MonoTop® 166 can improve the mechanical properties of the concrete surface after it is applied, including tensile strength, compressive strength and corrosion resistance.
6. Repair of infrastructure works
This product is often used in infrastructure works such as bridges, highways, factories, and other public works to repair cracks and damage, ensure the safety and durability of the project.
Features of Sika MonoTop® 166
Sika MonoTop 166 is a reliable choice, providing a quick and economical solution to prevent water ingress, sustainably protect a building and extend its life.
1. Comprehensive waterproofing
Sika MonoTop 166 is designed for forward and reverse waterproofing, ensuring optimal protection performance for buildings.
2. Easy application
The application becomes easy and quick thanks to the ability to use dry sprinkle or dilute with clean water to roll or spray on the surface.
3. Excellent adhesion
The product has excellent adhesion to concrete surfaces, creating a strong protective film.
4. Deep penetration
Sika MonoTop 166 has the ability to penetrate deep into the concrete structure, preventing the penetration of water and sealing the capillary networks in the concrete, helping to enhance the waterproofing ability.
5. Evaporation
The product allows steam to escape, helping to maintain moisture balance in the structure, preventing the formation of cracks due to water pressure.
Sika MonoTop 166 is not only the perfect choice for effective waterproofing but also enhances the sustainability and longevity of constructions.
Sika MonoTop® 166 Construction Process
1. Surface preparation
Before starting the application of Sika MonoTop® 166, it is necessary to ensure that the concrete and mortar surfaces have been properly cured:
- Ensure concrete and mortar surfaces are free of grease, dirt or other impurities that could cause flaking.
- If the surface is too smooth or contaminated, it is necessary to carry out sandblasting and soaking the surface before use.
- Cracks with a width greater than 0.4 mm and honeycomb holes up to 40 mm deep and 25 mm wide should be treated first.
2. Mixing mortar mix Sika MonoTop 166
- Mix three parts Sika MonoTop 166 powder with one part water by mass ratio until the mixture reaches the desired consistency.
- The mixing to be done in the blender does not exceed 500 RPM.
- Mixing time at least 3 minutes or until the mixture is homogeneous.
- Let the mixture stand for about 1-3 minutes after mixing, do not add water after mixing.
3. Apply wet method
- The surface must be wet before application to ensure the best penetration of the mortar mixture.
- Apply the first coat using a brush, brush or spray at a rate of 1 kg/m2.
- Allow the first coat to dry well before proceeding with the second coat.
- Apply the second coat perpendicular to the first layer with the rated amount of 1 kg/m2.
- Ensure that both screeds are applied evenly and smoothly for best performance.
4. Dry application (Passive waterproofing)
- After pouring fresh concrete, evenly spread Sika MonoTop® 166 powder on the concrete surface with a nominal amount of 3 - 3.5 kg/m2 to achieve the initial setting rate.
- Then perform a smoothing of the surface with the appropriate tool.
- Before pouring fresh concrete, sprinkle Sika MonoTop® 166 powder evenly on the concrete surface with a nominal amount of 2 kg/m2 to create an active waterproofing layer.
Note that the construction of Sika MonoTop® 166 needs to follow the correct procedures and instructions to ensure the best performance and durability for the project.
