Surface Preparation

Surface Preparation

Your coating will only look as good as the surface you begin with. In some cases, we can offer minor grinding and sanding for coating preparation.
8 STAGE PRETREATMENT

8 STAGE PRETREATMENT

We all know the chain is only as strong as its weakest link, and this is especially true with powder coating. Keystone Koating offers a proprietary 8 stage pre-treatment system to ensure that your metal substrate is clean and has optimal preparation prior to coating. Other powder coating companies might use anything from pressure washers to 5 stage systems. You deserve the best system possible and we have it!
Primer

Primer

Our in-line primer system allows for a seamless application of the best primers available. For outdoor applications, our primer process extends the life of the coating up to 4 times as long as non-primed surfaces. This, in turn, adds life to the product.

We offer a large selection of masking products to prevent coatings in threaded holes, studs, and various surfaces.
