SikaTop® Seal-107 KE

Waterproofing/damp-proofing cementitious slurry

SikaTop® Seal-107 KE is a two part polymer modified cementitious waterproof mortar slurry comprising of a liquid polymer and a cement-based mix incorporating special admixtures. It is slightly flexible (semi-rigid) to tolerate fine cracks and suitable in both interior and exterior applications.

  • Easy to apply by brush or in thin trowel applications 
  • No water required
  • Prebatched components
  • Hand or spray applied
  • Easy and fast mixing
  • Very good adhesion
  • Protects concrete against carbonation
  • Protects against water penetration
  • Non-corrosive to steel or iron
  • Overpaintable

Usage

SikaTop® Seal-107 KE is used for for the following applications: 
  • Interior and exterior waterproofing and damp-proofing of concrete, cementitious rendering, brickwork and blockwork
  • Protection of concrete structures against the effects of de-icing salts and freeze-thaw attack
  • Rigid waterproofing of basement walls in new construction and refurbishment 
  • Pore / blowhole filling and sealing fine “hairline” cracks in concrete structures (not subject to movement) 
  • Levelling mortar for concrete repair works
  • Waterproofing and protection of hydraulic structures, such as: basins, water tanks (also potable concrete water tanks), concrete piping, canals etc. 
  • Areas or works such as basements and cellars, terraces and balconies, swimming pools and fountains, RC gutters and planter boxes, bathroom toilets, and lift pits among others.

Application

Application Information

Fresh mortar density

~ 1.90 kg/l

Layer thickness

  • 0.75 mm min 
  • 2.0 mm max.

Ambient air temperature

+8°C min. / +35°C max.

Substrate temperature

+8°C min. / +35°C max.

Pot Life

~ 30 minutes at +22°C

Waiting time to overcoating

Waiting time between coats

+10°C ~ 12 hours

+20°C ~ 6 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

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.
Application steps

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
