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 X may be applied. Sikafloor® Marine Litosilo X 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 X 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).
