APPLICATION INFORMATION
Mixing ratio A : B = 1 : 4 (parts by weight)
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.
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.
10°C ~ 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.
BASIS OF PRODUCT DATA
All technical data stated in this Data Sheet are based
on laboratory tests. Actual measured data may vary
due to circumstances beyond our control.
IMPORTANT CONSIDERATIONS
SikaTop®-107 Seal KH is not a decorative treatment
and may display signs of “blooming” after rain or in
damp weather. This does not affect the
performance of the coating, in any way. Where
SikaTop®-107 Seal KH will be visible after completion
of the works, then the off-white colour, which
is aesthetically more pleasing, should be used.
Avoid application in direct sun and/or strong wind. Do
not add water in any circumstances. Apply only to
sound, prepared substrates. Do not exceed maximum
layer thickness.
For waterproofing or damp proofing application, always use at least 2 coats to give a total thickness of
between 1.5 to 2.0 mm. In areas of severe water penetration, three coats might be required.
Protect freshly applied material from rain.
For waterproofing / damp-proofing works, special attention is required to avoid puncturing the waterproof
coating with fixings. These must be accommodated by
surface bonding with either Sikadur® -31 CF Normal or
Sikaflex® Construction (AP) etc.
ECOLOGY, HEALTH AND SAFETY
APPLICATION INSTRUCTIONS
SUBSTRATE QUALITY / PRE-TREATMENT
The substrate must be structurally sound and free of
all traces of contaminants, loose and friable particles,
cement laitance, oils and grease etc. The concrete
“pull off” (tensile adhesive) strength must be > 1.0 N /
mm2.
General:
The substrate must be prepared by suitable mechanical preparation techniques such as high pressure water
jetting, needle guns, blastcleaning, scabblers etc. and
properly pre-wetted to a saturated surface dry condiPRODUCT DATA SHEET

tion.
For pore / blowhole filling:
Blastclean to remove all contaminants including from
within the pores / blowholes.
As a levelling mortar:
Prepare and clean all surfaces by suitable mechanical
means such as abrasive blast cleaning or equivalent to
ensure cement laitance, surface contamination and all
existing coatings are removed and all blowholesand
honeycombed areas are exposed. The resultant surface must be profiled to achieve maximum bond
strength.
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.
