Usage

Sikafloor® Marine-18 is applied on interior wet and dry accommodation areas, to level the surface prior to the application of deck finishing materials such as: carpets, tiles, parquet, rubber and vinyl. Sikafloor® Marine-18 is also part of the visco-elastic systems Sikafloor® Marine PK-90 N and Sikafloor® Marine VEM systems. This product is suitable for experienced professional users only. Tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.

CURE MECHANISM

Sikafloor® Marine-18 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-18 may be applied. For use in combination with Sikafloor® Marine PU-Red the application can be executed without primer.
Sikafloor® Marine-18 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 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.

Application

Apply the mortar with a steel board or a straight edge.
Sikafloor® Marine-18 has to be applied within 20 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-18 is covered with dense materials such as vinyl, epoxy 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.

Removal

Excess material can best be removed before curing with a trowel wipe or water.
Fresh Sikafloor® Marine-18 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.
