SIKA Sikafloor-256 W Epoxy Sealer satin matte 10kg

SIKA Sikafloor-256 W 10 kg – transparent, satin-matt epoxy sealer

Sikafloor-256 W is a water-based, transparent 2-component epoxy resin sealer with a satin-matt finish. It is used as a final layer on smooth epoxy and polyurethane floor coatings as well as on broadcast floorings.

The sealer removes the gloss from shiny coatings like Sikafloor-2600, imparts a sophisticated, satin-matt look, and protects broadcast color chips. It is UV-resistant and shows minimal yellowing. An anti-slip surface can also be created using the Sikafloor anti-slip agent.

Scope of delivery: 10 kg container (component A 6 kg + component B 4 kg), transparent.

One 10 kg container is sufficient for around 80 m² on smooth surfaces – ideal for several garages.

Application of Sikafloor-256 W

1. Check the substrate

The floor coating must be clean, dry, and free of dust, oil, and grease. Observe waiting times: On Sikafloor-264 Plus at +20 °C, seal no earlier than 18 hours and no later than 2 days after application.

2. Mixing

Stir component A, add component B, and mix for at least 2 minutes using an electric mixer (300–400 rpm). Avoid air entrapment, decant, and briefly mix again. For an anti-slip surface, stir in 2–4% anti-slip agent.

3. Application

Apply evenly with a short-pile sealing roller, ideally using a telescopic handle. Keep transitions damp and work wet-on-wet – material that has already begun to dry will lead to streaks or clouds if overworked.

4. Curing

At +20 °C, the surface is walkable after approx. 24 h. Protect from water and chemicals for at least 7 days. Clean tools immediately with water.

Note: Low temperatures and high humidity increase the risk of efflorescence. All technical data is derived from the current Sika product data sheet. Please refer to the product and safety data sheets, which you can download at the bottom of this page, before starting application.
