Description
Sika MonoTop®-107 Seal is a single-component, semi-flexible waterproofing mortar based on cement and modified polymers. Sika MonoTop®-107 is used as a protective coating.
APPS
It can be used with or without reinforcement, on concrete, mortar, stone, fiber cement supports and is indicated for:
-
Waterproofing of reservoirs, swimming pools, canals, etc.
-
Interior waterproofing of basements
-
Exterior waterproofing of buried walls
-
Repair and protection of surfaces exposed to the action of ice and de-icing salts: bridge parapets, eaves of terraces and roofs, cornices, etc.
-
Protection of concrete structures in the marine environment
-
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 for increasing strength (Principle 8, method 8.2 of UNE-EN 1504-9)
FEATURES

Consumption/Dosage:
- A minimum of 2 coats is required, and it may be necessary to go up to 3 in areas with extremely heavy leaks. As an indication: 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
- Maximum consumption per layer should not exceed 4 kg/m2 (2 mm thickness)
- Quality of the support: The support must be sound, clean, free of grease, oil and poorly adhering parts, surface grout and as uniform as possible.
- Preparation of the support/primer
- If necessary, the support must be prepared by mechanical means
- The absorbent supports will be previously moistened until saturation, avoiding puddles of water and starting to apply Sika MonoTop®-107 Seal when the surfaces acquire a matte appearance.
- Application conditions/limits
- Support temperature min. + 5°C/ max. +35°C
- Ambient temperature min. + 5°C./ max. +35°C
- Mixed: ~ 4.5 l of water per 25 kg bag
- Mixing time: Kneading should preferably be done using an electric mixer at low speed. To do this, pour the necessary quantity of water into a container with a wide opening and bottom, gradually add the Sika MonoTop®-107 Seal and mix for 2-3 minutes until a homogeneous mass is obtained.
