Vital Information for Interior Painting in Your Home

Have you ever wondered why some homes give away a welcoming feeling while others miss the mark? Well, that’s where the magic of interior painting steps in. It’s not just about choosing your favorite color; it’s about creating a vibe that outshines the word “home“. 

Color is not the only thing that matters when setting the right vibe! It comes down to an array of different aspects, including pre-planning and preparation, choosing the right type of paint, following the suitable paint technique, ensuring work safety, and dealing with challenges. Sounds a lot? Don’t worry. Custom Painting, Inc. has prepared an expert guide thanks to our expert house painters in Concord, CA. 

Pre-Planning and Preparation

Believe us when we say that the right plans bring out the right results. Being experts in the industry since 1982, Custom Painting, Inc. always recommends you to properly sort out your painting project before beginning it, rather than dealing with it in run-time. 

What Tools Do You Need?

Let’s start with the fundamental question: What do you need for the entire project? Apart from paint, here are a few essentials that would be helpful. 

  • Brushes and rollers: Tools used to apply paint to surfaces, with brushes being suitable for edges and corners and rollers for larger areas.
  • Painter’s tape: A type of tape used to mask off areas that should not be painted, such as trim, baseboards, and ceilings.
  • Stirring Sticks: Used to thoroughly mix paint for a more uniform result. 
  • Putty Knife: Handy for patching small holes or cracks in the walls before painting.
  • Caulk and Caulk Gun: Helps seal gaps and cracks in corners or between surfaces for a smoother finish. Be careful! Not everybody is able to handle these well. We recommend hiring a professional like Custom Painting, Inc., in case your walls have too many gaps or cracks. 
  • Drop cloths: Protective coverings used to prevent paint from dripping or spilling on floors, furniture, or other surfaces.
  • Sandpaper: Required to smooth surfaces and remove old paint or imperfections before painting.
  • Primer: A preparatory coating applied to surfaces before painting to improve adhesion, hide stains, and ensure a consistent finish.
  • Extension Pole for Rollers: Attaches to paint rollers and makes it easier to reach high areas without using a ladder.
  • Extras: YES, extras are a must. Keep a ladder (despite the extension pole), wall cleaning chemicals, wet cloth, and dump baskets with you, too!

Choosing the Right Paint

The most important part of interior painting is to choose the right paint. It’s really not that complicated. Let’s understand that with a table.

Finish Type

What sort of a finish you desire is also an important aspect to consider before you begin your painting project. That being said, it is NOT EASY to apply every finish yourself. Some of them, such as gloss finish, require perfection at every brushstroke without any chances for errors. Consult us, the best painters in Concord, CA, if you are planning for a gloss finish.

Preparing The Room

Okay, so now that you’ve got all the tools, it is time to prepare your room. It may sound difficult, but sure enough, it is as easy as ABC, given the fact that you follow these instructions precisely.

Clearing Furniture and Fixtures

Clearing the room involves moving out furniture and fixtures to create a spacious and unobstructed workspace. While one way is to cover the furniture with drop clothes, this is not what we recommend. 

Our interior painting team in Concord, CA, advises moving items to another room if possible. This helps in the easier application of paint without any hindrance. For larger pieces, use furniture sliders to avoid heavy lifting. 

Pro-Tip: Take this opportunity to clean and dust your furniture before moving it back into the freshly painted room for a pristine finish.

Patching and Repairing Walls

Before painting, inspect walls for cracks, holes, or imperfections. Use a putty knife to apply spackle (patching compound) to fill in these areas. Once dry, sand the patched spots to create a smooth surface. 

Helpful Advice: For larger holes, use a wall repair patch. 

Cleaning and Dusting Surfaces

Thoroughly cleaning and dusting surfaces is important if you are expecting a new look for your room. Why? Precisely because the paint would only appear neat on a clean surface instead of a dirty one. 

Use a mixture of mild detergent and water to clean walls, baseboards, and trim. Wipe down surfaces to remove dust, cobwebs, and any residues. A microfiber cloth and a soft sponge work well for cleaning.

Protecting Floors and Trim

To protect floors and trim, use drop cloths or plastic sheeting. Secure the coverings with painter’s tape to prevent accidental slips or shifts during the painting process. Use additional tape to cover baseboards and trim. 

Expert Tip: Invest in high-quality drop cloths to ensure thorough protection against paint splatters and drips. 

Painting Techniques

You can’t just randomly paint your interiors. There are special techniques most painters use to ensure a neat and aesthetically pleasing finish without any marks, blemishes, or lack of uniformity. 

Cutting In

Cutting in involves painting the edges and corners of a wall or ceiling using a brush before using a roller. This technique is helpful since it brings a clean and precise finish in areas where rollers might be challenging to navigate. 

For the best results, our house painters in Concord, CA, recommend one very important tip. Use a high-quality angled brush. Dip only one-third of the bristle length into the paint, and maintain a steady hand for sharp lines. Start from the top and work your way down for a professional look.


Rolling is the primary method for covering large wall areas efficiently. Use a paint roller to apply an even coat of paint. You should either work in a “W” or “M” pattern to avoid visible roller marks. 

Pro-Tip: Choose the right roller nap length for your surface: longer naps for textured surfaces and shorter naps for smooth surfaces. Roll in one direction for a consistent finish, and reload the roller regularly.

Proper Brush and Roller Techniques

Utilizing the right brush and roller techniques ensures an even and smooth application. For brushes, use long, even strokes to prevent streaks, and for rollers, apply consistent pressure. Remember that you need to feather out brush strokes to avoid visible lines, and for rollers, slightly overlap each stroke to blend the paint seamlessly.

Working Systematically

A systematic approach prevents missed spots and ensures uniform coverage. Start from the top and work your way down, painting one wall or section at a time. 

Remember to take breaks during work (Drink water and enjoy your artwork!).

Common Problems You’ll Face | How to Fix Them? 

Painting isn’t like 5th-grade homework. The more you paint, the better you learn. It’s a process where you’ll make mistakes and eventually improve. However, some of the common mistakes are addressed by our house painters in Concord, CA along with their fixes. 

Uneven Paint Coverage

The most common issue a beginner can face is uneven coverage. Certain areas may appear lighter or darker. It happens because of improper application techniques as well as the use of low-quality brushes and rollers. 

To fix this problem, ensure that you load your brushes or rollers with an adequate amount of paint and apply consistent pressure. REST IF NEEDED. Don’t go hard on yourself; otherwise the job won’t be done right! Additionally, invest in high-quality tools as it can significantly improve the overall coverage. 

Remember: If you notice unevenness after the first coat, allow it to dry completely before applying a second coat for a more uniform finish.

Drips and Runs

Drips and runs occur when there’s excess paint on your brushes or rollers. It is a problem because it can bring undesirable streaks on the painted surface. 

To avoid this problem, make sure to remove excess paint from your tools before applying it to the surface. If you do notice drips forming, catch them early using a brush or roller. Once the paint has dried, carefully sand the dripped areas and touch up as needed. FIXED!

Brush Marks

Visible brush marks can be a concern if your brush strokes are uneven or if the paint begins to dry too quickly. 

To prevent this issue, use high-quality brushes and work in the direction of the wood grain or in long, even strokes. Look for brushes with natural hog hair or synthetic nylon/polyester blends for durability and proper paint release. Choose brushes with flagged or tipped bristles for even application and a smoother finish.

If you’re dealing with quick drying times, consider adding a paint extender to the mix. This will slow down the drying process and bring a smoother finish.

IMPORTANT: Select a paint extender compatible with the type of paint (water-based or oil-based) you’re using.

Blotchy or Patchy Appearance

A blotchy or patchy appearance can arise from inconsistent color or sheen. To address this, ensure that you thoroughly mix the paint before starting your project. 

Using a primer can help create an even base, and applying additional coats as needed will contribute to a more uniform appearance. Be mindful to maintain a wet edge while painting to avoid lap marks.

Paint Bubbles

Bubbles forming beneath the paint can be a result of trapped air or moisture. To fix this issue, sand down the bubbled area, remove any loose paint, patch the surface, and repaint. 

It’s important to ensure proper ventilation during the painting process to prevent moisture buildup.
