Sikalastic®-1Komponent must be completely hardened before over-coating or water contact.
Guide for waiting times at the following temperatures:            

Times will vary due to ambient and substrate humidity

This depends on the substrate roughness; as a guide: ~1,2 kg/m2/mm

Sikalastic®-1Komponent can be mixed with a low speed (~ 500r/min) hand drill mixer, adding the right quantity of water according to the respective application. Once a homogeneous mix is obtained, continue mixing for 3–4 min. The mortar must be homogeneous and lump free.
Do not add any additional water or other ingredients.
Each bag must be entirely mixed, to avoid faulty particle size distribution of aggregates contained in the
powder component.

Special Requirements:
All connections between the substrate and pipe
entries, plant and equipment, and penetrations, must
be sealed and watertight. Joints in concrete, pipes or
anywhere else in the structure must also be sealed and
made watertight.
Use a coved detail at the floor/wall junctions.
Apply Sikalastic®-1Komponent by:
▪Trowel/spatula: Exerting good and even pressure
onto the substrate;
▪Brush/roller: In 2 directions (diagonally opposite /
cross-wise);
The optimum waterproofing performance is obtained
by applying Sikalastic®-1Komponent by trowel in at least 2 layers,
to a total thickness of at least 3 mm.
Application by brush must be undertaken with the
maximum attention to uniformly covering the whole
surface. The maximum recommended thickness for
these methods of application is 1 mm per layer. In
these situations, the application of min. 2–3 layers is
required (subsequent layers must be applied crosswise).
Wait until the first layer is dry before applying subsequent layers.
The application shall cover the whole surface of the
substrate in a uniform thickness.
Sikalastic®-1Komponent cannot be smoothed using float or sponge trowel. It is possible to smooth the surface as soon as the curing of the product is complete by light abrasion techniques.
Joints
At joints or other critical movement areas (for example
junctions with vertical surfaces), the waterproofing
may be reinforced by Sika® Seal Tape S. It
must be applied directly on the fresh first layer and
then covered by the second layer of Sikalastic®-1Komponent.Tilling Ceramic and vitreous tiles may be installed on Sikalastic ®-1Komponent using a polymer modified cement based tile adhesive in the Sika® CTA® range. All joints and gaps must be sealed.

Tools should be thoroughly cleaned with water before the material has set. Hardened mortar can only be removed mechanically.
