Layer Thickness
1.5 – 2.0 mm average thickness with Sika® Fab-1
Ambient Air Temperature
+10°C min. / +40°C max.
Substrate Temperature
+10°C min. / +40°C max.
Pot Life
~ 40 minutes at +27°C. Pot life will be shortened at higher temperatures.
Waiting Time / Overcoating
Waiting Time The waiting time between consecutive coats is 2 - 6 hours (at +30°C).
Overcoating For overcoating with cementitious materials, allow the second coat to harden for at least 3 days prior to overcoating. For use in water-retaining structures or for applying renders over it or for overcoating with non-cementitious materials, please contact Sika Technical Services.
Consumption
| Layer | Product | Consumption |
| 1 | SikaTop® Seal-107 IN | ~ 1.5 kg/m2 |
| 2 | Sika® Fab-1 | ~1 m2/m2 |
| 3 | SikaTop® Seal-107 IN | ~ 1.5 kg/m2 |
- Actual site consumption is dependent on the application area, substrate roughness, surface profile and thickness required
- Depending on the type of application, 2 coats are always required.
- For waterproofing upto 1m head pressure ~1.5 kg/m2 per coat.
- Above 1m head pressure ~ 2 kg/m2 per coat.
- Three coats may be required in areas of extremely high infiltration.
- Normally 3 kg/m2 of SikaTop® Seal-107 IN is sufficient to cover one square meter area. On well prepared smooth substrate the consumption would be less.
- Usage of Sika® Fab-1 is optional. For application areas, where Sika® Fab-1 is must, please consult Sika Technical Services.
EQUIPMENT
SikaTop® Seal-107 IN 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
The consistency of the mix can be altered by reducing the amount of Component A (liquid) to be used. Under normal circumstances, when the full quantities of both components are mixed together, a slurry consistency will result. For trowellable consistency use only 90% of component A. Mix in a clean container by slowly adding the powder component to the liquid component and stirring with low speed mixer (max. 500 rpm). Mix for 3 minutes until free from lumps.
APPLICATION
The surface must be pre-wetted to a saturated surface dry condition with no standing water at time of application. While the surface is still damp from saturation, apply the first coat and leave to harden for 2-6 hrs at +30°C before applying the second coat.
As a slurry Apply the mixed SikaTop® Seal-107 IN by hand using a hard plastic bristled brush or broom. Applied in the same direction. Apply the second coat of SikaTop® Seal-107 IN in crosswise direction to the first application as soon as first coat has hardened.
As a mortar SikaTop® Seal-107 IN is applied by trowel (e.g. for a smooth surface finish), the product must be mixed with a 10 % reduction of part A. Apply the second coat of SikaTop® Seal-107 IN as soon as the first coat has hardened. For pore / blowhole filling, tightly trowel into the pores / blowholes of the surface. For floor applications, to avoid risk of damage to the first coat, it is recommended that the second coat be applied before 24 hours. If the second coat is applied 12 hours or later, the first coat shall be slightly prewetted, preferably by using a fine spray. After the second coat has been applied, a better finish can be achieved by rubbing down with a soft, dry sponge. For more details, please contact Sika Technical Services.
CURING TREATMENT
For cement based products, proper curing is important for minimum 3 to 5 days. Protect newly applied SikaTop® Seal-107 IN against direct sunlight, wind, rain and frost to ensure full cement hydration and minimize 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.
