Spray application improves uniformity and rate accuracy, which is critical for interlayer bond and waterproofing film build. Roller or brush application can work for small areas but risks uneven thickness and trapped water, which slows curing. Surface texture and cleanliness determine wetting and adhesion, while temperature, humidity, and wind control evaporation and break time. Over application can cause slippage in tack coats or blistering in membranes, while under application reduces bond and waterproofing continuity. Equipment calibration and weather windows are essential for reliable performance.
