The method is only part of the result
A painter may spray to place the coating and then use a roller or brush where the surface and product call for it. Brushing, rolling and spraying can be parts of the same job.
Sherwin-Williams application FAQs explain that the material and coating influence the method. Ask how the proposed approach suits your wall or cabinet, rather than choosing solely on which tool sounds more professional.

Compare protection, access and finish
| Situation | Useful comparison |
|---|---|
| Occupied room | Protection, masking and how belongings remain separated |
| Large exterior wall | Access, surrounding surfaces and product application |
| Detailed doors or trim | Finish expectation, edge work and preparation |
| Textured surface | How the coating reaches the texture consistently |
A method that saves application time can still require careful setup. Compare the whole process, including cleanup, not only the time the tool touches the surface.
Cabinet spraying needs its own scope
Cabinet fronts are handled differently from broad house walls. Ask whether parts leave the property, how they are identified and how the box faces are treated onsite.
A smooth sample is useful, but also ask about the product system, existing finish and return-to-use instructions. Our cabinet painting guide covers the full scope beyond the spray finish.
What to ask before approving the method
Ask the contractor to explain protection, selected products, application requirements and how edges or difficult areas will be finished. Clarify what the final surface should look like and where a sample is appropriate.
Keep the method in proportion: a well-chosen tool cannot compensate for an unsound base or an unclear specification. Use quote comparison to evaluate the complete proposal.
