Min.2.0 kg/m² / Max. 4.0 kg/m² 

Consumption depends on substrate roughness, surface profile, wastage etc. Consumption : for water retaining structures use total 3.0 to 6.0 kg/m²  of SikaSeal®-105 PK depending on water head. Apply a minimum of two coats. For damp proofing, use a minimum of 2.0 kg/m²

Surfaces must be clean, sound, free from grease, oil and loosely adhering particles. The substrate must have a pull-off strength (tensile adhesive) of at least 1.0 N/mm². Use suitable mechanical methods such as abrasive blast cleaning, high pressure water jetting (minimum 150 bar), scabbling or needle guning. New or smooth faced concrete surfaces should be sandblasted. All surfaces must be as true and flat as possible. Blowholes and irregularities should be filled with suitable SikaTop® / Sika MonoTop® products. Saturate absorbent concrete surfaces thoroughly with water to achieve a surface saturated dry condition.

Stir component A (liquid) thoroughly before pouring into a clean mixing container. Add component B (powder) slowly while mixing continuously. Use forced action mixers or low speed electric mixers (maximum 500 rpm) with basket type mixing blades for 3 minutes avoiding entrapment of air. By adding the powder in portions, the desired application consistency can be obtained. For a trowelable consistency use about 90 % of component A approximately 4.5 kg).

While the substrate is still in a saturated surface dry condition, apply the first coat by notched trowel and leave to harden. Apply the second coat as soon as possible, after hardening of the first coat, to ensure proper adhesion between layers.

Slurry: Apply by spray or with a hard bristle brush or broom. Apply the second coat at right angles to the first.

Mortar: For the trowelable mortar use a notched trowel for the first coat. Apply the second coat into the notches and smoothen the surface. For floor applications, to avoid risk of damage to the first coat, it is recommended to apply the second coat after 24 hours. In such cases, the first coat should be slightly re-wetted. After application of the second coat, finish SikaSeal®-105 PK by rubbing down with a soft dry sponge.

Spray: The product can also be sprayed with a suitable mortar pump. For example Wagner PlastCoast 830 spraypack and a 4 mm nozzle. Refer to Sika’s Technical Department for further advice.

In case of a third coat, scratch the surface of the second coat with the edge of the trowel to provide a mechanical key.

Protect from rapid drying by applying an Antisol curing compound or protecting with polythene sheeting.

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