Using sandblasting

Using sandblastingIn the industry, people usually use this solution because its cleaning ability is outstanding and the execution time is short. Machinery and equipment are available leading to reduce the cost of labor.There are two kinds of sandblasting to treat the metal surface including:

Wet sandblasting: it will blast into the metal surface with a mixture of water and clean water with high pressure. The advantage of this method is to handle large rust film. This treatment does not cause dust, but the metal surface will get wet and need to dry before starting to repaint.

Dry sandblasting: Blast into metal surfaces with a mixture of water and clean sand with high pressure. This method helps to treat the metal surface well but causes a lot of dust. It is relatively eco-friendly to use sandblasting technique for large areas. Although this technique needs some specific equipment, in case you are experienced in sandblasting, you can rent the equipment to finish up the job.

Last but not least, you have to make a plan on disposing of the waste produced when conducting. Sandblasting brings about numerous benefits:

  • Time-saving
  • More efficient than other treatments.
  • The paint on the surface is removed evenly.
  • Cleaning the corners and hard-to-reach areas is easy.
  • It can preserve the use and longevity of the metal items.

Let’s jump right in, you’ll need an expert in sandblasting projects because he can not only minimize exposure to the grain but he also considers the necessary precautions for larger projects.

Still not convinced? You should follow this guide to carry out the process:

First, you ought to take advantage of a standard blast pot to reduce the amount of  media because it is easy for soda to produce clogs.

Here’s the deal, your standard blast pot offers the best results when the pot valve can control the flow of abrasive.

You should think over a wet blast injection because soda blasting releases more dust than traditional blasting. When you use a wet blast injection, you have more opportunities to pump water to limit the dust.

  • Wear goggles to protect their eyes
  • Don’t forget the protective gloves
  • Put on a mask to avoid inhaling the dust or debris
  • Wear old clothes because it is dangerous to wear again.

Using baking soda

An easy and fast fashion to remove paint from small metal items is to use baking soda combined with boiling water. Baking soda is a non-toxic paint removal. This is the reason why users should try using a mix of baking soda and boiling water to remove paint. This method is effective when applied for metal hardware like hinges and doorknobs. The abrasion of the baking soda removes the paint.The paint on those hinges or doorknobs is removed without comfortable fumes created by paint removal products.

Soda Blasting

Based on using baking soda, I will introduce you the new technique called “soda blasting”. “Soda blasting” method can remove paint from any sturdy surfaces, in particular metal. Soda blasting is the technique in which people blast baking soda onto the metal items surface by compressed air. This technique is eco-friendly and more effective and safer than sandblasting. Despite the different names, you can still apply the steps in sandblasting in this technique.Renting the tools for this kind of cleaning is easy because they are always available. The equipment used in soda blasting is soda blaster, which makes use of sodium bicarbonate or baking soda. Baking soda is softer than materials used in sandblasting including silicon carbide or aluminum oxide. The process is so gentle that it removes the paint on the metal items without harming the substrate.

FDA approves that soda blast media is a non-poisonous, silica-free non-sparking, non-combustible, environment-friendly, water-soluble and hard to wear down. These are the reasons why this method is so beneficial. Because of its properties, you can apply soda blasting to aluminum, stainless steel, chrome, etc.

After soda blasting, a layer of thin film is left in the items surface. This layer works to prevent flash rust within a month. Because of this, users have to remove this layer before repainting. You should follow the step-by-step guide to have the best result:

Soda BlastingStep 1: Prepare a surrounding area and wear protective items like gloves, goggles, etc.

Step 2: Blow out any cracks with a great flow of compressed air.

Step 3: Using a clean and hot cloth immersing the soapy water to wipe the item surfaces.

Step 4: Rinse, wring the cloth to remove this layer of film.

Step 5: Conduct this process again together with clean water until it’s clean completely.

Combining Numerous Methods To Remove Paint

The cheapest way might be a traditional one, which uses a paint scraper as a paint remover for metal objects. This technique works well on items with a thin paint layer. But wait, because the metal is so vulnerable to damage, this method is highly recommended to apply for iron items only. On top of that, people should combine two methods to remove completely the paint when it is in bad condition.

Combining two methods is the most effective way – use a paint scraper or a wire brush to scrape the paint away on a wide metal surface, then finish with another technique like using sandpaper to handle and scrub the corners and cracks. You can use a cordless drill with a wire brush. This is a good choice if you are shaving on a wide surface. Remember to use earplugs when operating the drill. Make sure to wipe away dirt and paint dust with a damp cloth while working. Remove any remaining paint patches. Use the clean cloth to scrub thoroughly, clean all pieces of peeling paint, sandy soil, grease and dirty marks on the surfaces of the items.
