SikaTop®-122 K11 Panel Proof

(former Davco® K11 Panel Pruf)

A FLEXIBLE 2-PART CEMENTITIOUS WATERPROOFING SYSTEM

SikaTop®-122 K11 Panel Proof is a premium grade, flexible two-part, polymer-modified cementitious waterproofing system.
After curing, SikaTop®-122 K11 Panel Proof forms a fully bonded, tough and yet flexible, seamless waterproofing membrane that can accommodate slight movement of structure.
SikaTop®-122 K11 Panel Proof can be skimmed, plastered and tiled on directly without any reduction in its bond strength.
SikaTop®-122 K11 Panel Proof's high performance makes it ideal for use in prefabricated bathroom units and precast panel wall system.

Application steps

SUBSTRATE PREPARATION

Clean the substrate of any protrusion or substances that may damage the membrane. Ensure all surfaces are free from dirt, dust, grease, oil, wax, curing compounds and any other loose contaminants.
Fill all voids, cracks, edges and angles with a suitable repair material, e.g. SikaGrout®-180 / SikaGrout®-128 (G280), so that the prepared surface is sound, even and flat to receive the membrane.

 


Pre-wet the surface with clean water. Do not allow water ponding. Porous surfaces should be primed with a suitable primer, e.g. Sikalastic®-500 Acrylic Primer AP prior to applying SikaTop®-122 K11 Panel Proof.

MIXING

Pour SikaTop®-122 K11 Panel Proof - Liquid part into a clean mixing container.

Then add Powder part gradually while mixing until a lump-free plastic consistency is achieved.

It is recommended that mechanical mixing (400 - 500 rpm) should be done for 2 - 3 minutes to ensure proper dispersion of the components.

NO ADDITION OF WATER IS ALLOWED.

APPLICATION

Apply the first coat of the mixed material onto the prepared surface using a brush or roller at an approximate wet film thickness of 0.7 mm per coat. Before a second coat is applied, the 1st coat must be left for approximately 2 - 3 hours depending on the thickness, substrate porosity and the temperature until it is dry. The second coat should be applied at a direction perpendicular to the first coat.
For application at joint areas, roll out the reinforcing mesh and press into the first coat of SikaTop®-122 K11 Panel Proof while it is still wet. Leave it to dry for 2 - 3 hours (depending on ambient temperature).
The second coat is then applied to completely fill the reinforcing mesh and left to cure for at least 12 hours (depending on ambient temperature and ventilation).
When SikaTop®-122 K11 Panel Proof has dried and cured, subsequent plastering or screeding material can then be applied on it.
