What Causes Orange Peel on Paint: Comprehensive Guide

Introduction

How Do Application Techniques Influence Orange Peel on Paint?

Getting a smooth finish when painting really depends on how you apply the paint. Orange peel, which looks bumpy like the skin of an orange, often comes from the way the paint is put on. Whether you’re spraying, rolling, or brushing, the method you choose can make a big difference in the final look.

For example, when using a spray gun, the distance from the surface, the angle you hold it, and how fast you move can all affect orange peel. If the spray gun is too far away, the paint might dry too quickly, leading to an uneven texture. On the other hand, if you hold it too close, you could end up with too much paint in one spot, which also creates bumps.

The way you overlap your strokes is also important. Not overlapping enough can leave some areas with thin paint, causing unevenness. Good overlapping helps the paint spread out smoothly, reducing the chance of orange peel. Plus, how fast you move the spray gun can change how the paint breaks up. Moving too slowly might make the paint sag, while going too fast can leave spots unpainted.

Knowing these application techniques is key for anyone who wants a professional-looking finish.
