| 2.6% (at 28 days) | (ASTM C121-90 (Reapproved 1999)) |
Application
Mixing ratio
| Used as slurry | A : B = 1 : 4 (parts by weight) |
| Used as mortar | A : B = 1 : 4.5 (parts by weight) |
Layer thickness
For ordinary water conditions : A total thickness of 1.5 mm. at total consumption 3 kg/m2
For high water pressure conditions: A total thickness of 2 mm. at total consumption 4 kg/m2
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.
| 10°C | ~ 12 hours |
| 20°C | ~ 6 hours |
| 30°C | ~ 3 hours |
If waiting time period exceeds 24 hours, lightly blastclean the surface. SikaTop®-107 Seal TH can be overpainted using solvent based primers or coatings. SikaTop®-107 Seal TH 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.
MIXING
Mixing Time : ~ 3 minutes
Mixing Tools : SikaTop®-107 Seal TH 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®-107 Seal TH either mechanically by spray or by hand using a stiff brush. Applied in the same direction.
- Apply the 2nd coat of SikaTop®-107 Seal TH, applied by brush in crosswise direction to the first application as soon as first coat has hardened.
As a mortar:
- When SikaTop®-107 Seal TH is applied by trowel (e.g. for a smooth surface finish), the product must be mixed with a 10% reduction of part A (~ 1 A : 4.5 B).
- Apply the 2nd coat of SikaTop®-107 Seal TH 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®-107 Seal TH 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 tool and application equipment with clean water immediately after use. Hardened / cured material can only be removed mechanically.
