Providing 30% more coverage, the WAL-BOARD TOOLS TEXTURE PRO 500 gets the job done quicker and more efficiently. It's used to spray acoustics, drywall mud, silica sand with primer, waterproofing, concrete overlays, and most other gravity fed materials. It features a patented trigger controlled air flow technology for more consistent texture, a sealable hopper to prevent mud from drying out, and an orifice plate with six versatile spray options. The reversible hopper reduces mess when spraying floors or ceilings. The soft grip trigger and handle feature a handy air adjustment valve allowing flow control at the gun instead of the pump.
