SikaTransfloor®-352 VSL

The curing of SikaTransfloor®-352 VSL takes place by a chemical reaction of the two components.
Higher temperatures speed up and lower temperatures slow down the curing process.

For steel decks, an anti-corrosion protection layer applied and intact as designed by the shipyard is a pre-requisite.
The anti-corrosion protection layer needs 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 sanding paper 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.
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.
The application area must be protected against dirt, sun light, water and draught.
Consider: the substrates must be 3 °C above the dew point prior and during application and the relative humidity must be below 80 %.
For other substrates and their pre-treatment consult the Sika Pre-Treatment Chart for Sikafloor® Marine.

SikaTransfloor®-352 VSL is poured and spread evenly by means of a suitable trowel or pin leveller. A spike roller may be used to improve levelling and deaeration.
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.

The product is walkable after 24 hours and is ready for the next stage in the process.

Uncured SikaTransfloor®-352 VSL 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 have to 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.

Layer thickness of the product 0.5 - 30 mm. If a higher layer thickness is needed the operation must be carried out in multiple applications with intermediate sanding + vaccuum cleaning of the cured product.

Beware of condensation. The substrate and uncured applied product must be at least 3 °C above dew point to reduce the risk of condensation.

Freshly applied SikaTransfloor®-352 VSL must be protected from damp, condensation and water for at least 1 day. Uncured material reacts in contact with water (foaming). For air heating use only electric powered warm air blower systems.

The product must be stored in original, unopened and undamaged packaging in dry conditions at temperatures between 5 °C and 30 °C. Always refer to packaging.
