SikaTop®-107 Seal NG

British Board of Agrement Certificate No. 95/3174.

Part A: liquid polymer and additive.

Part B: portland cement selected aggregate and admixtures.

12month from the date of production, stored in an unopened packaging.

Store properly in undamaged and unopened original sealed packaging in dry and cool conditions. Liquid component must be protected from frost.

Fresh mortar density: ~ 2.00 kg/l.

3 days                                         ~ 20 N/mm²                        (EN 196-1)

28 days                                ~ 35 N/mm²                        

Static: ~ 8.4 kN/mm²

Cured in water:      ~ 3.2 N/mm² after 14 days    exposure      (DIN 53455)

Cured in Air:              ~ 4.5 N/mm² after 14 days    exposure    

+8°C min. / +35°C max

                     +8°C min. / +35°C max

~ 30 minutes at +20°C

+10°C                               ~ 12 hours

+20°C                                ~ 6 hours

+30°C                                ~ 3 hours

If waiting time period exceeds 24 hours, lightly blastclean the surface. SikaTop® Seal-107 NG can be overpainted using solvent based primers or coatings. SikaTop® Seal-107 NG must cure for a minimum of 7 days before overcoating

Consumption is dependent on the substrate roughness, surface profile and

thickness of the layer applied. As a guide, ~ 2.0 kg/m²/mm (excluding al-

lowances for loss wastage, surface profile and porosity, etc.).

•                1 unit of 20 kg yields ~ 10 litres of mortar
•                   1 unit of 5 kg yields ~ 2.5 litres of mortar

Used as slurry: A : B = 1 : 4 (parts by weight)

Used as mortar: A : B = 1 : 4.5 (parts by weight)

Mixing Time: ~ 3 minutes. Mixing Tools: SikaTop® Seal107 NG 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.

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 NG either mechanically, by spray or by hand using a stiff brush. Apply the first layer in one direction. Apply the 2nd coat of SikaTop® Seal-107 NG, by brush, in a crosswise direction to the first application as soon as the first coat has hardened. As a mortar: When SikaTop® Seal-107 NG 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 NG as soon as the first coat has hardened. For pore / blowhole filling: tightly trowel into the pores / blowholes of the surface.

It is essential to cure SikaTop® Seal-107 NG 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.

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