Application Information

Mixing ratio

A : B = 1 : 4 (parts by weight)

Layer thickness

0.75 mm minimum / 2 mm maximum

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

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

~ 12 hours

20°C

~ 6 hours

30°C

~ 3 hours

Curing treatment

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

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

~12.5 L of mortar.

Application steps

MIXING

SikaTop® Seal -107 must be mechanically mixed for 3 minutes using a forced action mixer or in a clean drum using a drill and

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 slightly pre-wetted.

As a slurry:
Apply the mixed SikaTop®-107 Seal KH either mechanically by spray or by hand using a stiff brush. Applied in the same direction.
Apply the 2nd coat of SikaTop®-107 Seal KH, applied by brush in crosswise direction to the first application as soon as first coat has hardened.

As a mortar:
When SikaTop®-107 Seal KH 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 KH as soon as the first coat has hardened. For pore / blowhole filling, tightly trowel into the pores / blowholes of the surface.
