Usage

SikaTop® Seal-107 TZ is used for:
  • 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)
  • Waterproofing basement and cellars
  • Sealing fine “hairline” cracks in concrete structures (not subject to movement)
  • Levelling mortar for concrete repair works
  • Waterproofing of swimming pools, drinking water tanks and reservoirs among others
SikaTop® Seal-107 TZ can be used for concrete protection, in particular it is:
  • Suitable for protection against ingress 
  • Suitable for moisture control 
  • Suitable for increasing the resistivity

Fresh mortar density

Fresh mortar density: ~2.00kg/l

Layer thickness

Min. 0.75mm min – max. 1.5mm/coat

Ambient air temperature

+8°C min. / +35°C max.

Substrate temperature

+8°C min. / +35°C max.

Pot Life

~ 30 minutes at +20°C

Waiting time to overcoating

Waiting time between coats:

+10ºC

~12 hours

+20ºC

~6 hours

+30ºC

~3 hours

If waiting time period exceeds 24 hours, lightly blast clean the surface. SikaTop® Seal-107 TZ can be overpainted using solvent based primers or coatings. SikaTop® Seal-107 TZ 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.).

Yield

1 unit of 25kg yields ~ 12.5 litres of mortar.
Application steps

MIXING

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.

SikaTop® Seal-107 TZ 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.

Mixing should take place for at least 3 minutes.

APPLICATION

As a slurry:

Apply the mixed SikaTop® Seal-107 TZ either mechanically, by spray or by hand using a stiff brush. Applied in the same direction.

Apply the 2nd coat of SikaTop® Seal-107 TZ, applied by brush in crosswise direction to the first application as soon as first coat has hardened.

As a mortar:

When SikaTop® Seal-107 TZ is applied by trowel (e.g. for a smooth surface finish), the product must be mixed with a 10% reduction of part A (~ 1A : 4.5B).

Apply the 2nd coat of SikaTop® Seal-107 TZ as soon as the first coat has hardened.

For pore/blowhole filling, tightly trowel into the pores/blowholes of the surface.

CURING TREATMENT

It is essential to cure SikaTop® Seal-107 TZ immediately after application for a minimum of 3 to 5 days to ensure full cement hydration and to minimise cracking. Use polythene sheeting or similar approved methods.

 

CLEANING OF EQUIPMENT

Clean all tools and application equipment with clean water immediately after use. Hardened / cured material can only be removed mechanically
