Application Information

Mixing ratio

Consumption

Consumption

Depending on type of application, two (2) coats always required. Three (3) coats may be required in areas of extremely high infilteration.
1st coat consumption 1-1.5 kg/m2 on damp surface.
2nd coat consumption 0.8- 1 kg/m2 approx.
Application steps

SUBSTRATE QUALITY

The substrate must be sound, clean, free of grease, oil, friable parts, laitance and have a minimum resistance of 1 N/mm2

SUBSTRATE PREPARATION

In case of irregularities in the substrate, it should be first regularized with Sika Rep.
Absorbent substrates should be previously dampened until saturation (Saturated Dry Surface)  avoiding flooding 

MIXING

Mixing shall be carried preferably using a low speed (600 rpm) electric mixer.
For this purpose, in a wide mouth and bottom container, pour component B (powder) over component A (liquid) and mix for 2-3 minutes until a homogeneous mix is obtained.

APPLICATION

Application can be done by trowel, brush, long hair roller or by spraying.
SikaTop® Seal-107 EL can be installed with or without reinforcement 

Without reinforcement
If a notched trowel is used with teeth of 3-4 mm, the first layer is applied with the toothed edge and the second with plain edge, following the direction of the grooves.
The second layer of mortar should be applied when the first has hardened sufficiently (4 to 6 hours at 20 °C)
If a brush, roller, or spray is used for the application, apply two coats waiting for the first to harden before applying the second coat.

SikaTop® Seal-107 EL will extend as evenly as possible, avoiding accumulating material in corners, cavities or slits where cracks may appear.

With reinforcement 
SikaTop® Seal-107 EL reinforced with Sika fiber glass 107, anti-alakline fiber glass mesh, are capable of absorbing certain movements that may occur in the element on which they are applied, as well as acting as a bridge in the event that the support presents shrinkage cracks. The reinforcement must be carefully placed, avoiding any air occulsion due to the formation of folds and bags in the fiberglass mesh. The fiber glass mesh is joined by overlapping with a width of 3 to 5 cm.
The amount of SikaTop® Seal-107 EL to be applied must be the necessary amount to cover the entire reinforcement.

CURING TREATMENT

Measures should be taken to prevent the SikaTop® Seal-107 EL from drying out too quickly by using polyethylene sheets, wet sackclothes os Sika Antisol range of curing agents.

CLEANING OF EQUIPMENT

Clean all tools and application equipments with water immediately after use.
Hardened material can only be removed mechanically.
