Aerosol Finishing Tips
|Holding the can too close to the finishing surface can trap the propellant causing small bubbles to appear in the final finish. When you spray from too long a distance, you may end up with a rough overspray or 'sandpaper' finish because the solvent will dry before the complete spray hits the surface.
Proper Spraying pattern
The best method when spraying is to start from the front #1 and work towards the back #5. Never spray continuously. All aerosol spraying calls for short bursts, stop at the end of each stroke. Always start the new stroke off the piece moving onto the area being finished. This method eliminates overspray or puddling of material. Best results are obtained with several light coats in both directions as opposed to one heavy coat.
Keep Your Aerosol Products Clean
Always keep the spray head and dip tube clean upon completion of each finishing operation. After you have completed your work turn the can upside down and depress tip (as shown in illustration) for a few seconds until only vapor appears. This will clean the spray head and dip tube. Wipe off all overspray from head before you put the can away. Clogged sprayheads can be removed and soaked in lacquer thinner. Never leave spray cans any length of time with spray head removed as the sealing gasket will expand making insertion of a spray head at a later date difficult. Use a small thin knife to clean the slot in the bottom of the spray head. Inserting a fine needle intothe orifice of the head as shown in illustration will help clean clogged sprayheads.
Aerosol products should never be stored in an area where temperature may exceed 120° F.
Keep out of direct sunlight, trunks and rear window ledges of automobiles.
Most paint and lacquer products in aerosols are flammable. Never spray in basements or any room that has an open flame or gas fired appliances. Always spray in a well ventilated area for safety and health reasons.
Storage: cool, away from heat. Aerosol products should be used within 12 months from the date of purchase. Prolonged storage in areas where the temperature changes can break down the sealing gasket causing the propellant to escape slowly making the can inoperative.
