Waterproofing/damp-proofing cementitious slurry

SikaTop® Seal-107 Standard is a two part polymer modified cementitious waterproof mortar slurry comprising of a liquid polymer and a cement based mix incorporating special admixtures.

Usage

SikaTop® Seal-107 Standard 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
  • Rigid waterproofing of basement walls in new construction and refurbishment
  • Pore / blowhole filling
  • Sealing fine “hairline” cracks in concrete structures (not subject to movement)
  • Levelling mortar for concrete repair works
Advantages
  • Easy to apply by brush or in thin trowel applications
  • No water required
  • Prebatched components
  • Hand or spray applied
  • Easy and fast mixing
  • Very good adhesion
  • Protects concrete against carbonation
  • Protects against water penetration
  • Non-corrosive to steel or iron
  • Overpaintable
Packaging

25 kg (55.1 lb) units (20 kg (44.1 lb) bag and 5 kg (11 lb) pail)

Colour

Part A: white liquid Part B: grey or white powder Mixed product: cement grey

Typical Product Data
APPROVALS / STANDARDS

Conforms to the requirements of BS EN 1504-2:2004 Principles 2.2 & 8.2, Annex ZA2 Table ZA.2

Chemical Base

Part A: liquid polymer and additive
Part B: portland cement selected aggregate and admixtures

Shelf Life

9 months from date of production if stored properly in undamaged and unopened original sealed packaging

Storage Conditions

Store in dry and cool conditions. Liquid component must be protected from frost

Compressive Strength

3 days ~ 20 N/mm 2 (~ 2901 psi)
28 days ~ 35 N/mm 2 (~ 5076 psi)

Modulus of Elasticity in Compression

Static: ~ 8.4 kN/mm 2

Flexural Strength

3 days ~ 6 N/mm 2 (~ 870 psi)
28 days ~ 10 N/mm 2 (~ 1450 psi)

Tensile Strength

Cured in water: ~ 3.2 N/mm 2 (~ 464 psi) after 14 days exposure (According to DIN 53455)
Cured in air: ~ 4.5 N/mm 2 (~ 653 psi) after 14 days exposure

Tensile adhesion strength

2.0 to 3.0 N/mm 2 (failure in substrate)

Application
Fresh mortar density

~ 2.00 kg/l (~ 16.7 lb/gal)

Layer Thickness

0.75 mm (0.0295 in) min.

4.0 mm (0.157 in) max.

Ambient Air Temperature

+8°C (+46 °F) min. / +35°C (+95 °F) max.

Substrate Temperature

+8°C (+46 °F) min. / +35°C (+95 °F) max.

Pot Life

~ 30 minutes at +20°C (+68 °F)

Waiting Time / Overcoating

Waiting time between coats

+10°C (+50 °F)~ 12 hours
+20°C (+68 °F)~ 6 hours
+30°C (+86 °F)~ 3 hours

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

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.). 1 unit of 25 kg (55.1 lb) yields ~ 12.5 l of mortar.

MIXING

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

Used as mortar: A : B 1 : 4.5 - 5.1 ( parts by weight)

Mixing Time: ~ 3 minutes

SikaTop® Seal-107 Standard 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.

CURING TREATMENT

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

CLEANING OF TOOLS

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