ABSTRACT:
A fluid applicator for surfaces combining a spray-gun and dynamically displacable roller-brushes that features an extension wand formed from a plurality of coupled together segments. Each of the segments include a hollow and rigid tubular body completely encasing a flexible high pressure fluid hose. The tubular body includes a coupler connected at each end thereof, with the fluid hose extending between the couplers. Each coupler includes a large bore region having a plurality of threads. Adjacent segments are coupled together by a threaded barrel adapted to threadably engage adjacent large bore regions. Disposed opposite to the large bore regions of each coupler is a small bore region which has a plurality of threads which are adapted to engage the a threaded attachments associated with conventional high pressure fluid hoses. In this fashion, a fluid tight seal is formed between opposed ends of each segment.
