Description
SikaTop® Seal-107
Two-component, polymer-modified, cementitious waterproofing and protective slurry mortar for concrete. It is slightly flexible to tolerate fine cracks and suitable in both interior and exterior applications.
- Improves the watertightness of water-containing concrete tanks, reservoirs, and clearwells.
- Protects against water penetration, yet water vapor permeable (breathable).
- Excellent freeze/thaw resistance.
Usage
- Horizontal surfaces subjected to light foot traffic (balconies).
- For waterproofing of drinking water, tanks, reservoirs, and clearwells.
- For internal and external waterproofing and dampproofing concrete, mortar blockwork and brickwork.
- For protection of concrete structures against the deleterious effects of deicing salts and freeze/thaw cycles.
- For sealing “hairline” cracks in concrete structures not subject to movement surfaces.
- For interior and exterior waterproofing of basements.
- Vertical surfaces.
Advantages
- Improves the watertightness of water-containing concrete tanks, reservoirs, and clearwells.
- Protects against water penetration, yet water vapor permeable (breathable).
- Excellent freeze/thaw resistance.
- Good adhesion to sound, prepared substrates.
- Easy and fast mixing and application.
- Good abrasion resistance.
- Protects against concrete carbonation (80 mils SikaTop Seal 107 is equivalent to 6 inches of concrete).
- Can be mixed to slurry or trowelable consistency.
- Improves concrete/masonry appearance.
- Available in concrete gray and off-white.
- Approved for potable water contact.

Waiting time to overcoating
Waiting time between coats
+10°C ~ 12 hours
+20°C ~ 6 hours
+30°C ~ 3 hours
If waiting time period exceeds 24 hours, lightly blastclean the surface. SikaTop® Seal-107 KE can be overpainted using solvent based primers or coatings. SikaTop® Seal-107 KE must cure for a minimum of 7 days before overcoating
Consumption
Dependent on the substrate roughness, surface profile and thickness of the layer applied. As a guide, ~ 2.0 kg/m2/mm (excluding allowances for loss wastage, surface profile and porosity, etc.).
1 unit of 25 kg yields ~ 12.5 l of mortar.
Note: The consumption will vary depending on application area, substrate type, substrate roughness, surface profile, absorption of the surface and thickness required.
MIXING
- Used as slurry: A : B = 1 : 4 (parts by weight)
- Used as mortar: A : B 1 : 4.5 – 5.1 ( parts by weight)
- Mixing Time: ~ 3 minutes
Mixing Tools: SikaTop® Seal-107 KE must be mechanically mixed using a forced action mixer or in a clean drum using a drill and paddle (max. 500 rpm). A normal concrete free fall mixer is NOT suitable.
APPLICATION
Shake part A before using it. Pour approximately half of part A into the mixing container and add part B slowly while mixing. Add the remainder of part A and continue mixing until a uniform lump free consistency is achieved. The surface must be pre-wetted to a saturated surface dry condition before application.
- As a slurry: Apply the mixed SikaTop® Seal-107 KE either mechanically, by spray or by hand using a stiff brush. Applied in the same direction. Apply the 2nd coat of SikaTop® Seal-107 KE, applied by brush in crosswise direction to the first application as soon as first coat has hardened.
- As a mortar: When SikaTop® Seal-107 KE is applied by trowel (e.g. for a smooth surface finish), the product must be mixed with a 10% reduction of part A (~ 1A : 4.5 – 5.1B). Apply the 2nd coat of SikaTop® Seal-107 KE as soon as the first coat has hardened. For a smoother finish apply at 1.5mm maximum. For pore / blowhole filling, tightly trowel into the pores / blowholes of the surface before main application.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with clean water immediately after use. Hardened / cured material can only be removed mechanically
