Consumption

Consumption

Consumption depends on substrate roughness, surface profile, wastage etc. For water retaining structures, use total of 4.0 – 8.0 kg/m2/mm  of  SikaTop®-105 Seal KE depending on water head. Apply a minimum of two coats. For damp proofing, use a minimum of 2.0 kg/m2/mm.
Application steps

MIXING

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).

APPLICATION

APPLICATION

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.

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 SikaTop®-105 Seal KE by rubbing down with a soft dry sponge.

CURING TREATMENT

Protect from rapid drying by applying a Sika® Antisol® curing compound or protecting with polythene sheeting.

CLEANING OF EQUIPMENT

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