Key Takeaways
4 Pro [Painting](/guides/house-painters/painting-bad-work-[guide](/guides/house-painters/painting-quotes-apartment-guide)) Steps Professionals Actually Use
What separates [professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) painters from DIY attempts? They follow a consistent process on every job.
Here's what licensed painters do based on [professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) [Painting](/guides/house-painters/painting-bad-work-[guide](/guides/house-painters/painting-quotes-apartment-guide)) standards and techniques.
Step 1: Planning & Wall Inspection

[professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) painters begin every job with proper planning and wall inspection before touching any paint supplies.
Inspect your walls first. Check what you're actually working with before starting your project.
Wall Assessment
Examine your walls for:
<ul>
<li>Damage requiring repair</li>
<li>Existing wall finish type</li>
<li>Surface texture</li>
<li>Problem areas needing attention</li>
</ul>
Think about your lighting situation. How much natural light hits the room? What actually happens in this space? These factors influence paint color and finish selection.
Common Planning Mistakes
Skipping surface preparation on glossy finishes is a common error. Walls with existing finishes need proper prep for new paint to adhere correctly.
Material Selection
Use quality painter's tape for clean edges. Quality prep materials affect the final result.
Multiple brands of painter's tape are available at different price points. Premium options and standard options exist for different masking needs. Choose based on your project requirements and budget.
Primer Selection
Different primers are designed for different situations. Match your primer type to your specific needs before purchasing.
[Painting](/guides/house-painters/painting-bad-work-[guide](/guides/house-painters/painting-quotes-apartment-guide)) a light color over a similar existing light color in good condition? You might be able to skip primer for your specific situation. Some modern premium paints are marketed as having paint and primer combined. Assess your wall condition and project needs when deciding.
[professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) Approaches
Pros have different takes on whether to paint trim or walls first—it depends on trim complexity, wall texture, and personal technique.
Consider testing approaches on a small area to see which gives better results for your project.
Addressing Texture Issues
After patching holes and sanding smooth, repairs can show differently than surrounding walls due to differences in texture and porosity. Proper surface preparation helps create a more uniform appearance under the final coat of paint.
Proper priming of repaired areas helps prevent visible spots where repairs were made. The patched area has different porosity and texture, so it absorbs paint differently, which can create uneven appearance.
⚠️ Common Mistake to Avoid
Relying on "paint-and-primer-in-one" products for challenging surfaces is a trap. These are just thicker paints, not true primers. They will fail to block dark colors, seal stains, or properly bond to glossy finishes. Using them instead of a dedicated primer (e.g., shellac-based for stains or a bonding primer for slick surfaces) leads to bleed-through, peeling paint, and having to redo the entire job much sooner than you'd expect. Always use a separate, task-specific primer first.
Our Pro Recommendation
When comparing painter's tape, the real battle is FrogTape Multi-Surface vs. 3M ScotchBlue Original. While ScotchBlue is a decent budget option, we exclusively recommend FrogTape for any line that must be perfect. FrogTape’s patented PaintBlock Technology creates a legitimate micro-barrier when it touches latex paint, actively preventing bleed-through. In our experience, it delivers a noticeably crisper line than 3M on everything from smooth walls to lightly textured trim. The slightly higher cost is a small price to pay for avoiding tedious touch-ups.
What Most Guides Won't Tell You
Ditch your canvas drop cloths. Go to the hardware store and buy rolls of builder's paper or rosin paper instead. Unlike cloth, it lays completely flat, absorbs spills instantly without letting them soak through, and can be taped securely to the floor, eliminating the dangerous trip hazards and paint-tracking footprints common with bunched-up drop cloths.
Step 2: Surface Preparation

This is where many DIY jobs struggle.
Proper surface preparation prevents common paint problems like uneven finish or stains bleeding through coats.
Wall Repairs
For any cracks or holes, repair them properly before primer. Use quality spackle or joint compound appropriate for the damage size.
Once repairs are done, allow them to fully cure.
Stain Treatment
If you have discoloration on walls, you need stain-blocking primer on those spots. Make sure whatever caused any staining is resolved before [Painting](/guides/house-painters/painting-bad-work-[guide](/guides/house-painters/painting-quotes-apartment-guide)) over it.
Step 3: Priming
[professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) painters typically apply one coat of primer for proper coverage and paint adhesion.
Primer serves several purposes:
<ul>
<li>Creates uniform surface for paint</li>
<li>Improves paint adhesion</li>
<li>Blocks stains from bleeding through</li>
<li>Reduces number of paint coats needed</li>
</ul>
Allow proper drying time before applying paint coats.
Step 4: Paint Application
[professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) painters typically apply two coats of paint for the best coverage and durability.
Application Process
The key is allowing proper drying time between coats. Rushing this step compromises the final result.
Coat Coverage
Two coats provide:
<ul>
<li>Even color coverage</li>
<li>Better durability</li>
<li>[professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) appearance</li>
<li>Longer-lasting finish</li>
</ul>
[professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) Standards
[professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) painters follow a consistent process: one coat of primer and two coats of paint, with proper drying time between each coat.
This approach delivers the coverage and durability expected from [professional](/guides/house-painters/wall-painting-[guide](/guides/house-painters/painting-quotes-apartment-guide)-tips) work.
