An applicator and method of use is disclosed for applying coatings and paints to various surfaces. As shown, the sprayer may have an undercarriage frame that supports three-wheels. All three wheels may run parallel with the first wheels and second wheels attached to the sprayer frame via an undercarriage with the third wheel positioned behind and between both the first and second wheels on a separate arm or frame. The width of the sprayer booms may be adjusted. The undercarriage may be folded entirely or only a portion therein. The arm of the third wheel may be folded or telescope, as required by a particular application. A handle, which may be adjustable, may be positioned between the sprayer frame and the undercarriage. Use of the applicator according to the method discussed herein reduces operator fall exposure and increases application efficiency.

A method includes obtaining a spray device having a pump and a container containing an adhesive composition that does not include a propellant, operating the pump to pressurize the adhesive composition in the container to a pressure of 1 psi to 200 psi, spraying the adhesive composition from the container onto a roofing substrate to form an adhesive layer on the roofing substrate, and applying a roofing material to the adhesive layer on the roofing substrate.

A variety of dispensing manifolds which are removable connectable to a single deformable container having a single exit portion are disclosed. The dispensing manifolds of the present disclosure provide a single deformable container having a single exit with one or more outlets from which a fluid can be controllably dispensed. The present disclosure also provides a single force generation mechanism, a deformable container holding a fluid or substance, and dispensing mechanisms all on one machine, i.e., a carrier; a system that may also include a pressurized air source that assists a flow of a fluid; and a system that allows for a continuous flow a substance. The systems of the present disclosure provide a deformable container and a method of dispensing wherein, during dispensing, an actuation member is continuously free of contact with the fluid or substance within the container and the actuation member only contacts the exterior surface of the deformable container.

Devices configured to operate on an angled surface (e.g., a roof), and associated systems and methods are disclosed herein. In some embodiments, representative systems include an apparatus with a body assembly, an arm assembly coupled to the body assembly, and a material handling assembly coupled to the arm assembly. The body assembly can include a body frame, and a plurality of positioning assemblies coupleable to cables and configured to position and/or orient the body frame on the surface. The arm assembly includes a proximal end portion rotatably coupled to the body portion and a distal end portion opposite the proximal end portion. The material handling assembly is coupled to the distal end portion of the arm assembly and is configured to carry a surface material to be positioned on the angled surface.
