weberfloor 4660N Marine Elastic
weberfloor 4660N Marine Elastic is a self-levelling cement-based, pumpable, fibre-reinforced material designed for use in marine and offshore installations as an underlayment for floor coverings such as PVC, vinyl, linoleum, epoxy, stone and ceramics, carpets etc. 4660N Marine Elastic satisfies the requirements of the authorities and classification bodies for primary deck coverings.
The material quickly attains a high surface strength and is walkable after 2-3 hours.
Specially designed for Marine & Offshore constructions with high flexibility and strength to withstand the stress of a moving structure.
weberfloor 4660N Marine Elastic is a cement-based, pumpable, fibre-reinforced self-levelling material for steel-, galvanized steel- and aluminum decks in layer thicknesses from 4 to 50 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 2-3 hours. Final covering after 1-5 days (10 mm per day). 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 4660N meets all fire technical requirements as an underlayment for floor covering onboard passenger/merchant vessels and offshore installations.
weberfloor 4660N is designed for use in marine and offshore installations inside as an underlayment for floor coverings such as PVC, vinyl, linoleum, stone and ceramics, carpets, epoxy coatings etc. weberfloor 4660N satisfies the requirements of the authorities and classification bodies for primary deck coverings. weberfloor 4660N can be used as a bonded screed and as an underlayment screed for use on steel-, galvanized steel- or aluminum decks. It can also be used as a floating screed on top of insulation or applied on existing concrete/cement-based substrates for ship repair purposes. weberfloor 4660N is designed for application at thicknesses between 4 and 50 mm. When used as a floating screed the minimum layer thickness is 25 mm. If low weight or a thicker layer is required expanded clay aggregates (LWA) of grain size 2/4 mm can be added to the mix. This mixture can be applied in minimum thickness of 10 mm and should be covered with a 6 to 10 mm layer of weberfloor 4660N to achieve a surface smoothness ready for floor covering, but it is not an absolute requirement for stone and ceramics.
weberfloor 4660N 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 sub-floor for most types of floor covering. If weberfloor 4660N 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.
