A method and applicator for use in applying hazardous chemical solutions to surfaces. The invention employes a pen applicator to apply a measured amount of the hazardous chemical solution to a surface as a dispensing tip is applied to the surface. A typical pen applicator includes a tubular body in which a liquid absorbing material is disposed to hold the hazardous solution. A tip is in contact with the reservoir and one end of the tip acts as a wick to draw the solution from the reservoir to the tip, and the other end of the tip is configured to apply the solution to a surface when that end of the tip is placed in contact with the surface. A tip cover is provided to seal the tip and tip-end of the tubular body prevent inadvertent application of the solution and to preserve the shelf life. A cap or sealing member is provided at the end of the body to seal the reservoir. The size of the solution reservoir and the size and shape of the dispensing tip are chosen to provide the appropriate amount of solution to desired area of a surface. In the method of the present invention, the liquid dispensing tip is brought in contact with the surface and is rubbed over the desired area to dispense a controlled amount of the hazardous solution on the desired area of the surface. The applicator eliminates the amount of hazardous waste normally produced in the touch up processes, and reduces the number of process steps and time involved. The applicator is a simple, hand held, self feeding device, and is easily stored, is less messy to use, and requires less work area and process space. The applicator reduces solution waste by up to 99%, and the only waste material thrown away is an expired or empty applicator.
