A solid solution

Product description

Marlon Marine 1800 SL is a polymer modified cement-based self-levelling, pumpable and fine smoothing compound for steel-, galvanized steel- and aluminum decks in thickness from 2 to 30 mm (0.08-1.18 in).

By normal condition (20°C/68°F) and 80 % RH) Marlon Marine 1800 SL quickly attains a high surface strength and is walkable after 3-4 hours, depending of temperature. Final covering can be applied after 1-3 days. Note that the curing time depends on the substrate temperature and the ambient air temperature of the working area as well as the relative humidity. Marlon Marine 1800 SL can be applied by hand or applied by pump in bigger areas of application when using a mixer pump. The mixed Marlon Marine 1800 SL should be distributed over the surface using a steel trowel, toothed or flat spatula or spiked roller. Pot Life is approx. 20 min. Marlon Marine 1800 SL meets all requirements according to IMO FTP Code 2010 part 5.

Product advantages

For marine and offshore installations in all types of dry accommodation areas before laying carpet, vinyl, tiles, etc.

  • Smooth surface, easy to apply
  • Rapid drying, fast setting
  • One component, ready to mix
  • Pumpable
Surface preparation

Marlon Marine 1800 SL self levelling compound is to be applied inside ships on steel, galvanized steel, aluminum, concrete/cement- based, stone and ceramics and plywood boards, to level the surface before application of deck finishing materials such as: carpets, tiles, parquet, rubber and vinyl. For dense materials such as vinyl, epoxy coatings, membranes and for joint-free coating, etc., the remaining moisture has to be less than 5 %. For wet areas, please contact Marlon Marine for further information.

The shop-primed surface must be clean, free from dust, grease, oils and other substances, which may impair the adhesion. The whole surface has to be primed with Marlon Marine Primer F and after the drying of the primer Marlon Marine 1800 SL may be applied.

Marlon Marine 1800 SL cannot be applied directly on zinc-rich shop primed surface, aluminum or galvanized steel. In such case, please contact Marlon Marine.

Mixing process

Marlon Marine 1800 SL is mixed with cold fresh water to produce an easy flowing compound (amount of water, please see product specification).


After application, the finished areas should be protected against direct heat, sunlight and draft during the curing process. The materials may not be exposed to moisture and freezing temperatures. The applied compound Marlon Marine 1800 SL may not be exposed to freezing temperature, heat, sunlight and draft, before being fully cured.

Slow drying due to low temperature and/or poor film formation due to high humidity as well as non-proper priming can cause pinholes in the leveling layer.

For special applications not covered in this product datasheet, please contact Marlon Marine for further advice and guidance.
