The times given above are approximate and may vary with alternative environmental conditions.

Before Sikafloor®-304 W overcoating allow:

Values are based on a relative humidity of 70% and sufficient ventilation. Times are approximate and will change due to changing environmental conditions, especially temperature and humidity.

Note: Times are approximate and will be affected by changing ambient conditions.

Stir component A mechanically before mixing. Carefully mix components A + B in the prescribed mixing ratio before application. To prevent splashing or even spilling of the liquid, mix the components briefly at low speed using an infinitely variable electric stirrer. Then increase the stirring speed to a maximum of 300 rpm for intensive mixing. The mixing time is at least 3 minutes and is not completed until a homogeneous mixture is obtained. To obtain a uniform surface, 5% water can be added to the material. After adding water, stir for 1 minute. Then wait 1 minute and stir again for 1 minute. Transfer (repot) mixed material into a clean container, and mix again briefly as described above.

Application is carried out with a lint-free and solvent-resistant short-pile nylon or velour sealer roller.

To avoid multiple applications and wild overlaps, divide up work areas. Otherwise, an uneven surface appearance and streaking may occur. The application is carried out at the specified temperatures without direct sunlight and drafts.

For larger surfaces, it is recommended that at least 2 or better several persons carry out the application. One or more persons apply the material in one direction and another person spreads the freshly applied sealing material in a crosswise direction (90° angle). The last step is to roll the material perpendicular to the application direction using a 50 cm roller. The material is rolled in one direction only and the roller is lifted at the end of a strip.
On larger areas, a 50 cm wide roller should be used for re-rolling. The spreading roller must be impregnated/wetted with material and used only for spreading and never for applying the sealant.

The work must be carried out in a coordinated rhythm, the crosstalk must not be done too late. On large areas, the cross walk shall be rolled standing on the fresh surface. For this purpose, wear blunt nail or soccer shoes. Always work fresh in fresh and pay attention to an even optimal distribution when spreading. Avoid puddling, as cloud formation is possible.

Spray application:
Sikafloor®-304 W can be applied by airless spraying.
Ensure sufficient ventilation during application and curing.

Important: When sealing epoxy resin and polyurethane coatings, a sufficiently long curing time must be allowed before applying the sealant. At room temperature, wait at least 18 maximum 48 hrs.

Clean all tools and application equipment with water immediately after use. Hardened and/or cured material can only be removed mechanically.
