Sika Davco K11 Slurry - Crystallization Process Waterproofing

Pre-order stocks.

Davco K11 Slurry is a two component alkali-reactive (crystallization process) waterproofing system that forms a slightly flexible waterproofing membrane capable of bridging cracks and withstand hydrostatic pressure. Ideal for below grade surfaces against concrete decay and water borne corrosive salts.

Uses:

• For application in interior and exterior below grade surfaces against concrete decay and waterborne corrosive salts.
• For application in between horizontal structural slabs and toppings against hydrostatic pressure.
• Seals and protects masonry walls against algae or fungus growth caused by atmospheric pollutants and moisture.
• To form waterproofed underlayments for vinyl and carpet.
• Waterproof external walls against water seepage.
• Waterproofing of surfaces before laying marbles or ceramic tiles to help prevent efflorescence.
• Surface treatment to prevent absorption of concrete and autoclaved lightweight concrete (ALC) blocks.
• Suitable substrates: Concrete, brickwork, precast surface, lightweight blocks, etc.
• Potable water reservoir, tanks and cisterns.

Packaging:
34kg Set: Part A powder 25kg and Part B bonding agent 9kg

Product Preparation:

1. Always add DAVCO K11 Slurry Powder Part A to DAVCO K11 Bonding Agent Part B. While continuously stirring, mix for 2 - 3 minutes using a mechanical stirrer until a smooth creamy, lump - free consistency is achieved.
2. Leave to stand for several minutes until no bubbles are present in the mix.

Application:

1. Wet the substrate prior to application. The mixed DAVCO K11 Slurry is then applied onto the substrate in a stifling action using blocked brush.
2. Apply a minimum of 2 coats perpendicular to one another.
3. The 2nd coat must be applied while the 1st coat is still green, but must be sufficiently set so that it is not drawn off while applying the 2nd coat.
