SIKA Sikatop Seal 107 (A + B) Cement Based Waterproofing

SIKATOP SEAL 107 (A + B)
Brand: Sika
Weight: 20kg + 5kg
Colour: Grey

Main Features:

• 2 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.

Suitable 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 attacks.
• Exterior waterproofing of basement walls in new construction and refurbishment.
• Pore/blowhole filling.
• Rigid waterproofing of water tanks, swimming pools and etc.
• Sealing fine "hairline" cracks in concrete structures not subject to movement.
• Sealing internal basement walls against dampness.
• Leveling mortar for concrete repair works.
• Potable concrete water tanks.
• Basements.
• Terraces and balconies.
• Retaining walls.
• Swimming pools and fountains.
• RC gutters and planter boxes.
• Bathroom floors.
• Seawalls.

Characteristics and Benefits:

• Pre-batched components, mixes and applies easily.
• Slurry or trowelable 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.
• on-corrosive to steel and iron.

Coating System:

Coverage Depending on the type of application, two (2) coats are always required. Three (3) coats may be required in areas of extremely high infiltration.

1st coat consumption 1-1.5 kg/m2 on damp surface.

2nd coat consumption 0.8 - 1 kg/m2 approx.

Surface Preparation:

• Concrete, mortar and masonry surfaces must be clean (free from grease, oil and loosely adhering particles). 
• All surfaces must be as true and flat as possible. 
• Saturate absorbent surfaces thoroughly with water before application.

Application Mixing:

1) The consistency of the mix can be altered by reducing the amount of component (A) (liquid) to be used. 

2) Under normal circumstances, when the full quantities of both components are mixed together, a slurry consistency will result.

3) For a trowelable consistency use only 90% of component (A) (approx. 4.5 kg) Mix in a clean container by slowly adding the powder component to the liquid component and stirring with slow speed.
