Application
Fresh mortar density
~ 2.00 kg/l
Layer Thickness
0.75 mm min.
4.0 mm max.
Ambient Air Temperature
+8°C min. / +35°C max.
Substrate Temperature
+8°C min. / +35°C max.
Pot Life
~ 30 minutes at +20°C
Waiting Time / Overcoating
Waiting time between coats

SikaTop® Seal-107 Standard can be overpainted using solvent based primers or coatings. SikaTop® Seal-107 Standard 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
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
SikaTop® Seal-107 Standard 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.
CURING TREATMENT
It is essential to cure SikaTop® Seal-107 Standard 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 TOOLS
Clean all tools and application equipment with clean water immediately after use. Hardened / cured material can only be removed mechanically.
