Aerosol sandblast

Abstract

A pressurized gas or liquid mixture of particulates, or an aggregate of particulates, to be delivered in an aerosol spray through a self-contained container to remove paint, stains and the like from various surfaces, such as wood or metal. The aerosol aggregate mixture can additionally include paint removers or cleaners and is sprayed directly on objects or surfaces to abrasively remove paint or stains in an uniform manner without destroying any fine details.

1 . A sprayable material for use with an aerosol container comprising: 
 a solvent; and    abrasive particulates dispersed in the solvent, wherein the sprayable material is used to sandblast.    
   
   
       2 . The sprayable material according to  claim 1 , wherein the abrasive particulates are selected from a group consisting of glass beads, pumice, sand, sand paper, and mixtures thereof.  
   
   
       3 . The sprayable material according to  claim 1 , wherein the solvent is selected from a group consisting of water, paint remover, paint cleaner, engine cleaner, and mixtures thereof.  
   
   
       4 . The sprayable material according to  claim 3 , wherein the paint remover is water-based or solvent-based.  
   
   
       5 . The sprayable material according to  claim 1 , wherein the solvent is a citrus derivative.  
   
   
       6 . The sprayable material according to  claim 1 , wherein the solvent is xylene.  
   
   
       7 . The sprayable material according to  claim 1 , wherein the sprayable material further includes a propellant.  
   
   
       8 . The sprayable material according to  claim 1 , wherein the sprayable material further includes a thicksotropic.  
   
   
       9 . An aerosol system comprising a container, a sprayable material and an actuator assembly that sprays the sprayable material from the container, wherein the sprayable material comprises: 
 a solvent; and    abrasive particulates dispersed in the solvent, wherein the sprayable material is used to sandblast, and wherein the actuator assembly comprises:    an actuator body;    an orifice formed in the actuator body, wherein the orifice defines an inlet; and    a main valve and a lower valve operatively located between the sprayable material and the inlet, the valves being in fluid communication with one another and adapted to open and close communication between the sprayable material and the inlet.    
   
   
       10 . The aerosol system according to  claim 9 , wherein the abrasive particulates are selected from a group consisting of glass beads, pumice, sand, sand paper and mixtures thereof.  
   
   
       11 . The aerosol system according to  claim 9 , wherein the solvent is selected from a group consisting of water, paint remover, paint cleaner, engine cleaner and mixtures thereof.  
   
   
       12 . The aerosol system according to  claim 11 , wherein the paint remover is water-based or solvent-based.  
   
   
       13 . The aerosol system according to  claim 9 , wherein the solvent is a citrus derivative.  
   
   
       14 . The aerosol system according to  claim 9 , wherein the solvent is xylene.  
   
   
       15 . The aerosol system according to  claim 9 , wherein the sprayable material further includes a propellant.  
   
   
       16 . The aerosol system according to  claim 9 , wherein the sprayable material further includes a thicksotropic.  
   
   
       17 . An aerosol system comprising a container, a sprayable material and an actuator assembly that sprays the sprayable material from the container, wherein the sprayable material comprises: 
 a solvent, the solvent being selected from a group consisting of water, paint remover, paint cleaner, engine cleaner and mixtures thereof; and    abrasive particulates dispersed in the solvent, the abrasive particulates being selected from a group consisting of glass beads, pumice, sand, sand paper and mixtures thereof, and wherein the actuator assembly comprises:    an actuator body;    an orifice formed in the actuator body, wherein the orifice defines an inlet; and    a main valve and a lower valve operatively located between the sprayable material and the inlet, the valves being in fluid communication with one another and adapted to open and close communication between the sprayable material and the inlet.    
   
   
       18 . A method for removing a top layer from a substrate comprising: 
 applying a sprayable material from a hand-held aerosol container onto a top layer of a substrate, wherein the sprayable material comprises 
 a solvent; and  
 abrasive particulates dispersed in the solvent, and wherein the aerosol container includes an actuator assembly that comprises 
 an actuator body,  
 an orifice formed in the actuator body, wherein the orifice defines an inlet, and  
 a main valve and a lower valve operatively located between the sprayable material and the inlet, the valves being in fluid communication with one another and adapted to open and close communication between the sprayable material and the inlet; and  
 
   repeating the applying step for a number of times sufficient to remove the top layer from the substrate.    
   
   
       19 . The method according to  claim 18 , wherein the substrate is a wall and the top layer to be removed is selected from the group consisting of rust, stains, old paint, and graffiti.  
   
   
       20 . The method according to  claim 18 , wherein the substrate is an engine and the top layer to be removed is selected from the group consisting of oil, grime, and rust.
