SikaTop® Seal-107 (MY)
Cementitious waterproofing slurry and protective coating
Previously known as SikaTop® Seal-107. SikaTop® Seal-107 (MY) is a two part polymer modified cementitious waterproof mortar slurry comprising of a liquid polymer and a cement based mix incorporating special admixtures. It is applied to concrete and mortar to prevent water infiltration.
- Pre-batched components - mixes and applies easily
- Slurry or trowellable consistency
- Good adhesion to sound, prepared substrates
- Increased frost and salt resistance
- Protects against concrete carbonation and water penetration
- Non toxic - suitable for contact with drinking water
- Non corrosive to steel or iron
Usage
SikaTop® Seal-107 (MY) is used for:- Interior and exterior waterproofing and damp-proofing of concrete, cementitious rendering, brickwork and blockwork
- Protection of concrete structures against the effects of de-icing salts and freeze-thaw attack
- Exterior waterproofing of basement walls in new construction and refurbishment
- Pore / blowhole filling
- Rigid waterproofing of water tanks, bathrooms, toilets, etc.
- Sealing fine “hairline” cracks in concrete structures not subject to movement
- Sealing internal basement walls against dampness
- Levelling mortar for concrete repair works
- Potable concrete water tanks
- Basements
- Terraces and balconies
- Retaining walls
- Fountains
- RC gutters and planter boxes
- Bathroom floors
- Seawalls

1.9–2.0 kg/l
Pot Life
~30 minutes (at +30 °C). Pot life will be shortened at higher temperatures.
Waiting Time / Overcoating
Waiting Time
The waiting time between coats is 4–8 hours (at +30 °C).
Overcoating
For overcoating with other 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's Technical Service Department.
Curing Treatment
Generally not required but precautions should be taken for applications done directly under sunlight and windy conditions.
Consumption
- Waterproofing bathrooms, terraces and balconies is 1.0 kg/m² per coat
- Waterproofing coating more than 1 m waterhead is 1.5 kg/m² per coat
- As a protective coating is 2.0 kg/m² per coat
Notes:
- SikaTop® Seal-107 (MY) must be applied in minimum of 2 coats, including upturns up to 300 mm height
- 3 coats may be required in areas of extremely high infiltration
- For upturn more 300 mm height, please contact Sika's Technical Service Department.
MIXING
Under normal circumstances, when the full quantities of both components are mixed together, a slurry consistency will result. The consistency of the mix can be altered by reducing the amount of part A to be used. For trowel application, use only 90 % of part A (approximately 4.5 kg).
Mix in a clean container by slowly adding part B to part A and stir with a low speed mixer for about 3 minutes. Use within 30 minutes.
SikaTop® Seal-107 (MY) must be mechanically mixed using a forced action mixer or in a clean drum using a drill and paddle (max. 500 rpm). A normal drum mixer or free-fall mixer is NOT suitable.
APPLICATION
Whilst the substrate is still damp from saturation, apply the first coat. Leave to harden for approximately 4–8 hours at temperatures above 20 °C before applying the second coat.
As a slurry
Apply the mixed SikaTop® Seal-107 (MY) by hand using a hard plastic bristled brush or broom. Applied in the same direction. Apply the second coat of SikaTop® Seal-107 (MY) in crosswise direction to the first application as soon as first coat has hardened.
As a mortar
SikaTop® Seal-107 (MY) 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 (MY) 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.

CURING TREATMENT
Generally not required but precautions should be taken for applications done directly under sunlight and windy conditions.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be mechanically removed.
