Essential Interior Painting Tips for a Flawless Finish

Essential Interior Painting Tips for a Flawless Finish

Rodrigo Pereira Teixeira |

A fresh coat of paint can instantly transform any room—but achieving a smooth, even, professional-looking finish takes more than just opening a can and rolling it on the wall. Here are some of the most common questions about interior painting, answered by our experts, to help you get it right the first time.


1. How important is surface preparation?

Extremely important. Skipping prep is the fastest way to end up with uneven results. Always:

  • Clean walls to remove dust, grease, and fingerprints

  • Fill holes and cracks

  • Sand rough spots

  • Remove loose or peeling paint

Proper prep ensures your paint adheres well and looks flawless. Need help choosing prep tools? Browse our paint collection for primers, fillers, and sanding supplies.


2. Should I use primer before painting?

In most cases, yes—especially when:

  • Painting over dark colours

  • Covering stains

  • Painting new drywall

  • Switching from glossy to matte finishes

A high-quality primer can save you time and paint. Our services team can recommend the right formula for your project.


3. What’s the best paint finish for interior walls?

It depends on the room:

  • Matte/Flat: Hides imperfections; best for low-traffic areas

  • Eggshell/Satin: Slight sheen; great for living rooms and bedrooms

  • Semi-Gloss/Gloss: Durable and washable; ideal for kitchens, bathrooms, and trim

4. How do I avoid streaks and lap marks?

  • Use a quality roller with the right nap for your wall texture

  • Paint in small sections and keep a wet edge

  • Work in a “W” pattern for even coverage

For large or challenging rooms, consider hiring a pro through our Painter Order Form.


5. What’s the ideal painting order in a room?

The standard sequence is:

  • Ceiling

  • Walls

  • Trim and baseboards

  • Doors

This minimizes touch-ups and keeps your finish clean.


6. How can I protect my floors and furniture?

  • Use drop cloths or plastic sheeting

  • Mask off trim, windows, and outlets with painter’s tape

  • Move furniture to the center of the room or remove it entirely

Good preparation not only protects your space but also speeds up cleanup.


7. How long should I wait between coats?

Follow the paint manufacturer’s instructions—usually 2–4 hours between coats. Rushing can lead to peeling, uneven sheen, or roller marks.
