Abstract: A portable wall and ceiling texture machine applicator is housed in a relatively small cabinet mounted on relatively large rear wheels for easy pulling up stairs and on swivel front casters for easy steering. A first material delivery system includes a variable speed pump which delivers particulate texture material at a selected flow rate which enables a creative application of texture. A completely separate delivery system delivers pressurized air to a spray head which merges the particulate texture material and pressurized air to spray it onto a wall or ceiling. Separate power cords supply energy for delivering the particulate texture material and pressurized air so that existing 15-amp house supply circuits may be used. The spray head may be on either a pole gun or a hand gun. A check valve on the spray head prevents a back flow of the particulate material when the spray head is turned off.
