Airless Sprayer

Airless sprayers are the preferred application method for roof membrane coatings on large surface areas. Unlike conventional spray guns that use compressed air to atomise the paint (causing significant overspray and material waste), airless sprayers force the coating through a precision-engineered spray tip that breaks the material into a fine, fan-shaped spray pattern through hydraulic pressure alone. This produces a thicker, more uniform coating film with less overspray and faster coverage rates. For roof restoration work, airless sprayers are typically powered by petrol or electric motors and can handle the heavy-bodied, high-solids coating products used in roof membrane systems. A quality airless sprayer can apply a single coat of roof membrane to an average residential roof in 2 to 3 hours — compared to 8 hours or more by roller. The spray tip size is selected to match the coating viscosity and the desired film thickness, with common tip sizes for roof membrane work ranging from 0.021" to 0.031". In Gippsland, Town & Country Roofing uses professional airless spray equipment for the application of Dulux Acratex primer and membrane coats during roof restoration. The sprayers are complemented by roller and brush work in detailed areas such as ridge caps, flashings, and edges where overspray must be controlled. The combination of spray and hand application ensures complete, uniform coverage across the entire roof surface.
