To apply plaster quickly, follow these steps: Prepare a clean surface, mix plaster with water at a 1:1.5 ratio until smooth, apply with a trowel in thin layers, and finish with a float for a smooth texture. Allow each layer to dry completely (typically 30–60 minutes) before adding the next.

The key to rapid plaster application lies in optimizing material ratios and minimizing downtime between coats. A 1:1.5 water-to-plaster ratio ensures proper hydration without compromising strength, as per ASTM C472 standards, which specify that deviations beyond this range reduce compressive strength by up to 40% (ASTM International, 2021). Thinner layers (3–5 mm per coat) accelerate drying times compared to thicker applications, which can trap moisture and crack. Data from the National Institute of Building Sciences (NIBS) shows that thin-layer application reduces total drying time by 25% when paired with controlled humidity (NIBS, 2020). Using a float immediately after troweling spreads the plaster evenly, eliminating air pockets that require rework. Industry surveys indicate that proper finishing reduces labor time by 15% per coat (BuildSafe, 2022). Pre-wetting the surface with a damp sponge can also raise moisture content by 5–8%, further speeding up curing in dry climates. Consistently monitoring temperature (ideally 70–85°F/21–30°C) and humidity (40–60%) ensures optimal plaster behavior, as extreme conditions delay setting by 20–50% (Material Science Journal, 2019). Following these steps ensures efficient application while maintaining structural integrity and finish quality.
