The laser has been used in various types of industries for varied industrial applications.
And paint industry is not an exception.
Think of your old garden furniture, a pole, a metal statue, a metal pipe, or a car that is heavily rusted.
You may not be touching them for years, thinking that, you can damage the surface if you try to clear out the old paint or rust on them.
But not anymore, there are sophisticated methods like laser removal that can help.
Laser rust and paint removal is a process to clean up the metal parts for refinishing the surfaces.
Believe it or not, laser removal can help you blast rust and paint off the surface without making damage to the substrate.
Depending on the size of the project you are handling this can be done in a matter of a few minutes to several hours.
All you need is the help of an experienced professional who can do that for you using a handheld laser paint removal machine.
Why Laser Cleaning?
Commercial laser systems are typically designed to remove rusted paint from large-sized steel and aluminum structures (such as bridges, ships, power transmission towers, vehicles, and more).
The process of laser being highly technological can be used for cleaning up weather topcoat finishes.
The metal or wood surface can then be easily refinished with newer coatings over layers of base coats.
The process is so beneficial that it is today also being used by several contractors while renovating the homes for accomplishing tasks like heavy rust removal, paint stripping, varnish coat removal, grease removal, and de-coating of metals.
Not only these but the powerful laser cleaning can also be used safely for a variety of other household applications (like mold cleaning, surface preparation, etc) on a number of different surfaces.
How does Laser Process Work?
The laser paint removal process generally involves the usage of a laser beam machine which is pulsed directly onto the wood or metal surface with a specific energy density.
The energy density is usually kept higher than the paint ablation threshold.
But it’s lower than the actual substrate ablation threshold on which it’s used.
In the process, the laser energy is repeatedly pulsed in short pulses at a pre-set rate.
The shockwaves generated due to the high pulse rate laser is so intense that it makes the coatings remove the metal surface fast.
Pros and Cons of Laser Ablation Paint Removal
One of the best benefits offered by the laser rust and paint cleaning process is it’s eco-friendly and precise.
Chemical processes, which would otherwise be used for similar projects are not only damaging to the environment but also imprecise.
This simply means that you cannot use these chemical stripping methods for tasks that require precision and high accuracy.
Using a laser paint stripping method is a way to go!
What makes a handheld vacuum-like laser device even more intriguing is the fact that it comes with a vacuum system that can easily suck up the vaporized paint, dust, rust, or other contaminants; making the process clean and mess-free.
The only drawback of using laser paint and rust removal for household applications is its high cost.
Since the laser paint removal tools cost expensive (even the cheapest one can cost thousands of dollars), the process of hiring a professional and getting the job done can be expensive too.
Rust, paint, varnishes, and various other contaminants can be hard to remove, especially when thick layers have been deposited one over another for a long time.
Although expensive, using a high-intensity laser beam can be a game-changer.
Especially for professionals like plasma cutters, MIG welders, automotive manufacturers, auto mechanics, scrapers, etc, techniques like pulsed lasers for paint removal can be a real-time savior.
If you are really worried about damaging the base metal while crimping off the residue, laser paint and rust removal are well worth your efforts and money.
