weberfloor 4670N Marine Base
weberfloor 4670N Marine Base
weberfloor 4670N Marine Base is a rapid drying mortar for use on steel-, galvanised steel- and aluminium decks as well as existing concrete and stone and ceramics. It has a somewhat coarser structure than self-levelling compounds, and needs to be primed and fine smoothed prior to laying floor coverings. weber.floor 4670 is supplied as pre-mixed dry powder, water is added on site of construction.

weberfloor 4670N Marine Base is a rapid drying mortar for use on steel-, galvanised steel- and aluminium decks as well as existing concrete and stone and ceramics. It has a somewhat coarser structure than self-levelling compounds, and needs to be primed and fine smoothed prior to laying floor coverings. weber.floor 4670 is supplied as pre-mixed dry powder, water is added on site of construction. The material is mixed and applied by hand, quickly attains a high surface strength and is walkable after 1-3 hours. Final covering after 1 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 4670N meets all fire technical requirements as a subfloor for floor coverings in passenger/merchant vessels and offshore installations according to IMO Res. A.687 (17). For special applications not covered in this product datasheet, please contact Weber for further advice and guidance. Also refer to applicable national regulations.
weberfloor 4670 is designed for use in marine- and offshore installations inside in cabin areas, wet areas and other high traffic areas, where there are demands for rapid surface strength for rapid laying of floor coverings. weberfloor 4670 satisfies the requirements of the authorities and classification bodies for screed mortars. weberfloor 4670 can be used as a bonded screed on steel-, galvanized steel- or aluminum decks. It can also be applied on existing concrete/cement based or stone and ceramics substrates for ship repair purposes. weberfloor 4670 is hand-applied at thicknesses between 20 and 150 mm, and its soil consistency makes it easy to build slopes, form smaller ramps etc. weberfloor 4670 is not suitable as a final subfloor for floor finishes and should be covered with weberfloor 4660/weberfloor 4675/weberfloor 4690 to achieve a surface smoothness ready for floor covering, but it is not an absolute requirement for stone and ceramics. The combination of weberfloor 4665 and weberfloor 4660/weber- floor 4675/weberfloor 4690 is suitable as a finished subfloor for most floor coverings, such as PVC, vinyl, linoleum, stone and ceramics, carpets etc.
weberfloor 4670 is designed for use as a subfloor for most coverings and should not be used without a final floor finish. The floor covering should be applied as soon as the conditions allow. 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 screed mortar has hardened and been smoothed, it will provide a finished sub-floor for most types of floor covering. If weberfloor 4670 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.
