2.1 – 2.2 kg/L (part A + B mixed)

1 Kg / m² / coat (2 coats recommended)

1 set of 25 kg yields ~ 12 l of mortar.

Pour half of component A (liquid) into mixing vessel. Add all component B (powder) and mix until you have slurry of uniform consistency. Add rest of component A and mix again until you have uniform, lump-free mixture. A mechanical slow speed mixer is recommended. Mixing time 2-3 minutes. If SikaTop®-107 Seal PK is to be applied by trowel, use only 90% of com-ponent A (liquid).

By Brush:

On vertical surface use suitable brush with synthetic bristles. On horizontal surface use rubber slide or push-broom.

By Trowel:

For first coat use tooth trowel with 3 mm teeth, for second coat use normal flat trowel. Always apply a minimum of 2 coats, the first coat on the still damp, (pre-wetted) substrate. The second coat is to be applied after the first coat started to set and can support the following coat, usually after 2-6 hours, depending on climate. Finish off by brushing with dry sponge when setting of second coat has started. Maximum waiting time between first and second coats is 48 hours.

As with all cement based products, curing is important. Protect the freshly applied product against direct sunlight and strong winds. Use damp hessian or plastic sheet. Protect the applied SikaTop®-107 Seal PK from rain and water splashes until fully hardened. (± 6 hours).

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