Areas of Application

Sikafloor® Marine Litosilo N is applied on interior decks, as primary deck covering or as sound reducing floating floor prior to the application of deck finishing materials such as: carpets, tiles, parquet, rubber and vinyl. There are various combinations with Sikafloor® Marine Litosilo N to achieve an A 60 division and combined with insulation and a Sika visco-elastic system it can in addition be used to damp structure borne noise. 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 Litosilo 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 Litosilo N may be applied. Sikafloor® Marine Litosilo 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.

For floating floors, the mineral wool has to be sound (not damaged), clean, dry free from grease, oils and other substances.
It’s a must to use re-enforcement such as wire mesh or similar for the whole area and extra re-enforcement (e.g. steel plates) where ever a higher load is expected such as in both sides of doors areas, staircases, etc.

Further details for floating floors consult the Application Manual of Sikafloor® Marine Litosilo N and its approved combinations.

Consider that prior applications of vinyl and carpet coverings, a thin self levelling mortar such as Sikafloor® Marine 100 has to be applied to obtain an even floor. For wet areas the surface has to be treated with a water resistant membrane (e.g. Sikafloor® Marine Elastic).

Application

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

Sikafloor® Marine Litosilo 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 Litosilo N is covered with dense materials such as vinyl, epoxy or polyurethane coatings, etc., ensure that the remaining moisture level is below 4 %.
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.
