Würth floor joint sealant must not be used for sealing glass or in swimming pools. For full holding power, a 14-day curing time at approx. 20°C (material and floor temperature) must be observed. The colour can be affected by environmental factors and external influences (chemicals, high temperature, UV radiation, unsuitable paint/smoothing agents). These potential changes in colour do not affect the technical and protective properties of the product. Elastic sealants must never be painted. Coats of paint have limited elasticity and can crack and flake when movement occurs in the joint. Colour changes due to intolerances cannot be excluded. For sealant-compatible coats of paint, the joint edges should be trimmed by a maximum of 1 mm (test in accordance with DIN 52 452-4). Do not use on bituminous substrates or other substrates that can bleed oil or plasticisers, e.g. EPDM or natural rubber (or carry out preliminary tests). Good chemical and mechanical capacity (however, ensure that joints are not damaged by hard cleaning brushes; additional chemicals used may reduce resistance). Tool cleaning: All tools and processing accessories must be immediately cleaned with Würth adhesive remover (Art. 089010063). Hardened sealant residues can only be removed mechanically. In its uncured state, the product must not be mixed or come into contact with substances that react with isocyanate, in particular alcohols that, for example, are a component of spirit, many diluting agents, cleaning agents and formwork oil, otherwise the final reaction (linking) of the material will be impaired or prevented.

The floor joint sealant is particularly suitable for joining movement and connection joints indoors and outdoors in food-related areas. Suitable for floor joints in concrete and screed exposed to static loads or rolling traffic, e.g. joints in warehouses, production halls, parking decks, yard areas, underground garages, for tiled floors in entrance halls and stairwells.
The joint flanks must be intact, stable, clean, dry and free from oil, grease and loose components, concrete slurries,
paint, hydrophobing agents and anti-graffiti coatings.
After appropriate surface preparation and insertion of a tightly fitting closed-cell PE round cord, the joint sealant is inserted into the properly prepared joint with a suitable gun. It must be ensured that the sealant is inserted with no bubbles or cavities and that there is complete contact with joint edges. The joint surface should then be smoothed over with a suitable smoothing tool or spatula, ensuring the sealant is pressed against the adhesive surfaces and the backing material. If required, the surface can be smoothed out with Würth sealant smoothing agent (art. 08933 or 0893003). Please observe the "General Notes on Application for Sealants" overview sheet. For more information, please refer to the technical data sheet.
