Sand Blasting Before Powder Coating in Preston, WA

Do you have a car or motorcycle that you put a lot of time and money into? Or, maybe you want to maintain the appearance of handrails, staircases or patio furniture. These are only a few of the items that can benefit from powder coating.

Powder coating is the process of coating metal with a plastic finish applied in powder form and baked to a fluid state to bond it to the metal surface. This extends the life of your metal products and gives them a decorative finish to increase their aesthetic appeal. The experts at Powder Vision, Inc., provide powder coating in Preston, WA, on all types of stainless steel, steel, aluminum and brass products.

The Powder Coating Process

Pretreatment steps: Before powder coating begins, we will use a sandblaster to completely clean the surface of oils, dirt, paint, rust, corrosion and damaged plating. Any trace of these elements can interfere with the powder coating process. If the surface of your item is not thoroughly clean and polished before the powder coating is applied, this can result in imperfections in the finish or an overall failed powder coating process.

Using a sandblaster on your item before powder coating also gives the object a surface profile. The sanding process will leave multiple small scratches in the metal item, creating high points and low points, called a profile. This profile allows the powder coat to seep into these many high points and low points. In turn, the powder coating will adhere much better to the metal item than if the metal was completely smooth. Without this surface profile, the powder coating process may peel off the surface.

How powder coating works: The powder coating process will also begin with other pretreatment steps, such as alkaline cleaning and clean water rinsing to prevent any rust from forming. Once dry, the metal parts are coated and cured in an oven at 400 degrees. The cure time will vary depending on the thickness and density of the parts. This creates a lasting bond that will ensure superior durability of your metal item. Once curing is complete, the parts are removed from the oven for cooling. We then carefully inspect each item.

Powder coating can be applied over galvanize and provides an environmentally safe finish while releasing no fumes, carcinogens or hazardous by-products.

Maintain the high-quality powder coating results: To maintain your powder coated surface, avoid harsh solvents, use wax to help the powder coating last longer and keep a close eye on decorative areas, which are generally more likely to collect dirt and other corrosive elements. Make sure to keep these areas clean and protected. For larger structures like staircases or outdoor furniture, pressure washing is the best method to retain their shine without compromising their surfaces.
