Verbrauch

Gehobeltes Holz: 8-12 m²/L. Sägeraues: 5-8 m²/L. Immer 2 Anstriche. Terrasse 20 m² × 2: 40 m² ÷ 7 = ~6 Liter. In Deutschland: Osmo, Remmers und Bondex sind führende Marken. Dünnschichtlasur für Außen: wetterfest und UV-beständig.

Anwendung

Zwischen 10-25°C, kein Regen in 48 Stunden. Zwischen den Anstrichen leicht anschleifen (Korn 220). Vorbereitung (Reinigung + Trocknung) bestimmt 80% der Haltbarkeit.

⚡ CalcWolf Insight

Oil-based stains penetrate deeper than water-based and last 20-30% longer on horizontal surfaces. However, water-based stains are easier to apply, dry faster, and clean up with water. For deck floors (heavy foot traffic), oil-based is worth the extra hassle.
