About this product

weberfloor 4680N Marine Light is a lightweight, polymer modified cement-based levelling and fine smoothing compound for steel-, galvanized steel- and aluminum decks in layer thicknesses from 0 to 20 mm. The material is supplied as pre- mixed dry powder. Water is added on site of construction. The screed can be hand-applied or pumped in towards place of application using a Weber mixer pump, and requires only light mechanical handling with a trowel, spatula or spiked roller to achieve an adequate surface evenness for a floor covering.

The material quickly attains a high surface strength and is walkable after 2-4 hours. Final covering can be laid after 1-3 days. Note that the curing time depends on the substrate temperature and the ambient air temperature of the work area as well as the relative humidity. weberfloor 4680 meets all fire technical requirements as an underlayment for floor coverings onboard passenger/merchant vessels and offshore installations according to IMO Res. A.687 (16). For special applications not covered in this product datasheet, please contact Weber for further advice and guidance. Also refer to current national regulations.

Area of use

weberfloor 4680N is designed for use in marine and offshore installations inside in light traffic areas, mainly foot traffic,as an underlayment for floor coverings such as PVC, vinyl, linoleum, stone and ceramics, carpets etc. weberfloor 4680N satisfies the requirements of the authorities and classification bodies for primary deck coverings. weberfloor 4680N can be used as a bonded screed and as an underlayment screed for use on steel-, galvanized steel- or aluminum decks. weberfloor 4680N is designed for application at thicknesses between 0 and 20 mm.

weberfloor 4680N is designed for use as an underlayment for most types of floor coverings and should not be used without a final floor finish. The floor covering should be applied as soon as the conditions apply. The product should not be used in a humid environment over 95% RH. Any special requirements for the floor covering concerned should be observed, comply with the requirements from the floor covering manufacturer. When the smoothed floor has hardened, and been rubbed down where necessary, it will provide a finished subfloor for most floor coverings. If weberfloor 4680N is not covered within the stipulated drying time, or used as a working platform or transport area during the building process, sufficient cleaning is important to achieve a suitable substrate for the floor covering.
