PRODUCT BENEFITS

  • Lightweight leveling mortar
  • Low E-modulus
  • One component, ready to mix
  • Easy applicable
  • Also suitable for sloped surfaces
  • Can be pumped
 

Areas of Application

Sikafloor® Marine KG-202 N is applied on interior decks, to level the surface prior to the application of deck finishing materials such as: carpets, tiles, parquet, rubber and vinyl. It is suitable for application in wet and dry accommodation areas. For wet areas prior to tiles application, the substrate has to be additionally treated with a water resistant membrane (e.g. Sikafloor® Marine Elastic). This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

CURE MECHANISM

Sikafloor® Marine KG-202 N cures by way of hydraulic curing.

Application

Application Information

Surface preparation

For leveling applications, the surface has to be clean, free from dust, grease, oils and other substances, which may impair adhesion. Rust has to be removed with a steel brush or other appropriate means, followed by vacuum cleaning.
The surface has to be primed with Sikafloor® Marine Primer C using a long hair roller. After drying of the Sikafloor® Marine Primer C, Sikafloor® Marine KG-202 N may be applied.
For wet areas the surface has to be treated with a water resistant membrane (e.g. Sikafloor® Marine Elastic).
Before application of vinyl and carpet coverings, ensure that a thin self levelling mortar such as Sikafloor® Marine 100 is applied to obtain an even floor.
Sikafloor® Marine KG-202 N applications on aluminum or zinc rich shop primer coated decks, require a tie coat of SikaCor® ZP Primer or another suitable tie coat prior the priming step with Sikafloor® Marine Primer C.

Application

Apply the mortar with a steel board or a straight edge.

Sikafloor® Marine KG-202 N has to be applied within 30 minutes after mixing. At temperatures above 30 °C the open time will be reduced to 10 minutes or less.

For advice on selecting and setting up a suitable pump system, contact the System Engineering Department of Sika Industry.

 

Curing

After application, the finished areas have to be protected against direct heat (e.g. cutting or welding from beneath), sunlight and draught during the curing process for at least 12 hours.
Before Sikafloor® Marine KG-202 N is covered with dense materials such as vinyl, epoxy or polyurethane coatings, etc., ensure that the remaining moisture level is below 4 %. If covered by an epoxy or polyurthane material, a smoothening layer of Sikafloor® Marine-118 FC or -190 may be needed.
Test procedure to determine the dryness (according ASTM D 4263): put a PE-plastic foil 1 m x 1 m on the surface of the applied mortar floor, tape the perimeter and leave for one day. The curing is complete if there is no water condensation on the foil or a visible color difference between covered and uncovered surface.

Removal

Excess material can best be removed before curing with a trowel wipe or water.
Fresh Sikafloor® Marine KG-202 N may be removed from tools and equipment with water. Once cured, the material can only be removed mechanically.
Exposed hands and skin shall be washed immediately with water. Use a suitable skin protection hand cream.
