Descripción
Sika MonoTop®-107 Seal is a one-component semi-flexible waterproofing mortar based on cement and modified polymers. Sika MonoTop®-107 is used as a protective coating.
APPLICATIONS
It can be used with or without reinforcement, on concrete, mortar, stone, fiber cement supports and is indicated for:
-
Waterproofing of tanks, swimming pools, canals, etc.
-
Interior waterproofing in basements
-
Exterior waterproofing of buried walls
-
Repair and protection of surfaces exposed to the action of ice and deicing salts: bridge parapets, terrace and roof overhangs, cornices, etc.
-
Protection of concrete structures in marine environments
-
Waterproofing of drinking water tanks
- Sika MonoTop®-107 Seal can be used to protect concrete structures:
- Suitable for protection against penetration (Principle 1, method 1.3 of UNE-EN 1504-9)
- Suitable for humidity control (Principle 2, method 2.2 of UNE-EN 1504-9).
-
Suitable to increase resistance (Principle 8, method 8.2 of UNE-EN 1504-9)
CHARACTERISTICS
- Easy mixing and application
- Excellent adhesion on healthy support
- Impermeable to water. Permeable to water vapor
- High resistance to ice and deicing salts
- Good resistance to ozone. Slightly flexible compared to normal mortar
- Slows the progression of carbonation
- It does not attack armor or metal elements. It is not corrosive, flammable or toxic

System information
Application Details
-
Consumption/Dosage:
- A minimum of 2 layers are required, and it may be necessary to go up to 3 in areas with extremely strong leaks. As indicative data: For protection against frost: 2 kg/m2 and layer
- For waterproofing; depending on the height of the water column:
- With H < 1 m.: up to 1.5 kg/m2 and layer
- With H > 1 m.: up to 2 kg/m2 and layer
- The maximum consumption per layer must not exceed 4 kg/m2 (2 mm thickness)
- Quality of the support: The support must be healthy, clean, free of grease, oil and poorly adhered parts, surface grout and as uniform as possible.
- Support Preparation/Primer
- If necessary, the support must be prepared by mechanical means
- The absorbent supports will be previously moistened until saturation, avoiding puddles and starting to apply Sika MonoTop®-107 Seal when the surfaces acquire a matte appearance.
- Conditions of Application/Limitations
- Support temperature min.+ 5°C/ max. +35o C
- Ambient temperature min.+ 5°C./ max. +35o C
- Mixed: ~ 4.5 l of water per 25 kg bag
- Mixing time: Kneading will be carried out preferably using a low speed electric mixer. To do this, pour the necessary amount of water into a container with a wide mouth and bottom, gradually add Sika MonoTop®-107 Seal and mix for 2-3 minutes until a homogeneous mass is obtained.
