Powder coating is a popular and durable finishing process used in many industries. As a leading local powder coating service in San Diego, Anocote Powder understands the importance of knowing which materials are suitable for this process. While powder coating is versatile, there are certain materials and items that cannot be powder coated. In this article, we’ll explore what can’t be powder coated and why, helping you make informed decisions about your finishing needs.

Local Powder Coating: Understanding the Process

Before diving into what can’t be powder coated, let’s briefly review what powder coating is and how it’s applied in local powder coating shops.

Powder coating is a dry finishing process that involves applying electrostatically charged powder to a surface, then curing it under heat to create a durable, attractive finish. This method is widely used for its durability, environmental friendliness, and cost-effectiveness.

Powder Coating and Sandblasting: A Powerful Combination

At Anocote Powder, we often combine powder coating and sandblasting for optimal results. Sandblasting is a crucial step in the powder coating process, preparing surfaces by removing old paint, rust, and other contaminants. This ensures better adhesion and a smoother finish for the powder coat.

Sandblasting Powder Coat Preparation: Essential Steps

The sandblasting powder coat preparation process involves several key steps:

  1. Surface cleaning
  2. Removal of old finishes or corrosion
  3. Creating an ideal surface profile for powder adhesion
  4. Final cleaning before powder application

This thorough preparation is what sets professional powder coating services apart from DIY attempts.
