Sikafloor® Marine-579

The curing of Sikafloor® Marine-579 takes place by a chemical reaction of the two components.
Higher temperatures speed up and lower temperatures slow down the curing process.

For advice contact the Technical Department of Sika Industry.

For steel decks, an anti-corrosion protection layer applied and intact as designed by the shipyard is a pre-requisite.
The surface need to be clean, free of dirt, dust, grease, oil and loose particles before application of the SikaCor® ZP Primer. The adhesion between the anti-corrosion protection layer and SikaCor® ZP Primer must be verified.
Aluminum deck needs to be clean, free of dirt, dust, grease, oil and loose particles. The aluminum substrate must be sanded with 40 – 80 grit and dust free vacuum cleaned before application of SikaCor® ZP Primer (Tiecoat).
In the case of cementitious substrates, it must be ensured that the laitance layer is completely removed. This is usually achieved by grinding. All dust, loose and friable material must be completely removed by vacuum before the next application.
Repairs to the substrate, filling of cracks, holes/voids or surface levelling must be carried out first. Repair areas must be cured before applying primers.
Ensure the substrate moisture content is equal or less than 4 % (Calcium carbide method (CM-method). Apply Sikafloor®-150/-151 as a primer to obtain a closed pore free surface.
Backing substrate for prefab installations must be clean, dry and free of all contaminants such as dirt, oil, grease and loose friable material.
2-C polyurethane substrates need usually to be sanded with 40 – 80 grit sanding paper up to diamond disc. In case the substrate is not clean, it is required to clean it before the sanding process to ensure no debris is sanded into the surface. All dust, loose and friable material must be completely removed from the surface by vacuum cleaning before next application.
For more information and other substrates refer to the Sika Pre-Treatment Chart for Sikafloor® Marine Applications.
The application area must be protected against dirt, sun light, water and draught.

Sikafloor® Marine-579 is poured and spread evenly by means of a suitable trowel or pin leveller. A spike roller may be used to improve levelling and de-airing.
For liquid application on cambers and slopes multiple applications steps might be needed.
A seamless finish can be achieved when a “wet” edge is maintained during application.

Indications regarding curing details see table below.

Uncured Sikafloor® Marine-579 can be removed from tools and equipment with Sika® Colma Cleaner or another suitable solvent. Once cured, the material can only be removed mechanically.
Hands and exposed skin shall be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water.
Do not use solvents on skin.

Beware of condensation. The substrate and uncured applied product must be at least 3 °C above dew point to reduce the risk of condensation.
Sikafloor® Marine-579 used for Sikafloor® Marine teak deck system is only available in specific colors.
Freshly applied Sikafloor® Marine-579 must be protected from damp, condensation and water for at least 1 day. Uncured material reacts in contact with water (foaming).
For consistent color matching, ensure the product in each area is applied from the same batch numbers.
For air heating use only electric powered warm air blower systems.
If Sikafloor® Marine-579 is used in interior areas and exposed to UV light, the floor must be protected by a pigmented sealer, such as Sikafloor® Marine-505.

Both components of Sikafloor® Marine-579 have to be kept between 5 °C and 30 °C in a dry place. Do not expose it to direct sunlight. After opening of the packaging, the contents need to be protected against moisture.

Minimum temperature during transportation is 5 °C.
