Preparation

• Preparation of the surface is critical to the spray adhering to the surface and forming sharp lines, as any contaminants will disrupt the paint. Use a high-power air blower to clear the area of any dirt, dust or debris. Newly created asphalt or concrete needs to be completely dried and properly cured to accept striping. Clean all areas contaminated with gasoline, motor oil or other petroleum-based products with cleaner to remove all residue to ensure that the paint adheres properly.
  
  

Forms

• When using a hand-held painter, it is essential to use forms to create straight, crisp lines. Heavy cardboard creates an ideal moveable form to create uniform stripes and is disposable. Spray slowly over the form, ensuring that the surface is evenly coated. Online retailers sell pre-made line strip forms made from plastic and heavy cardboard in pre-set lengths for parking spaces and handicap logo stencils.
  
  

Machines

• Choose a line striping machine that fits your application, as too large of a sprayer makes small, intricate lines difficult. Inspect the surface for any large indentations, cracks or holes that will obstruct the wheels of the sprayer and either fix them with a patch or cover them with a thin board. Check the wheels for even inflation, as differences in air pressure can cause the machine to stray to the side. Move the sprayer in a uniform motion to keep the spray straight and uniform on the surface. Stop and reposition the unit before attempting a perpendicular line.
  
  

Equipment Maintenance

• Clean your line striping equipment regularly throughout the job to remove any paint buildup or leaking paint that can transfer to the surface accidentally. Clean the spray tip periodically with paint solvent to clear all dried paint from the inside and outside, which can result in strayed or blurry lines. Routinely checking your sprayer for correct air pressure, paint spray volume and the hopper to ensure it has efficient paint will prevent any problems with the spray quality.
