A Brief Guide For Pre-Paint Surface Preparation: 5 Easy Tips To A Flawless Finish

Proper surface preparation is the key if you’re planning to paint interior walls. A well-prepared wall will ensure a smooth, even finish that lasts. Here are five tips to help you get the job done right.

By following these simple steps, you’ll avoid having to paint again sooner than you’d like, and your home will look fresh and new.

Tip #1: Start with a Clean Slate:

The first step to prepping your walls for painting is to remove any existing wallpaper or paint. It will help ensure that the new paint adheres properly and doesn’t peel. To remove wallpaper:

  1. Start by scoring the surface with a utility knife.
  2. Use a sponge or cloth to apply a wallpaper remover solution to the scored area.
  3. Let it soak in before using a putty knife or scraper to remove the wallpaper.

Tip #2: Repair Cracks and Holes:

Assuming that your walls are already clean, the next step is to repair any cracks or holes. For small cracks, use caulk to fill them in. For larger holes, use joint compound. First, apply the joint compound to the hole with a putty or taping knife. Then, smooth out the surface with sandpaper.

Tip # 3: Apply a Degreaser:

Paint won’t stick to a greasy surface. For this reason, it’s critical to use a high-quality degreaser on grease-coated walls, particularly in places above the stove and around light switches, so that that paint may adhere to the surface.

To apply the degreaser:

  1. Allow it to sit for a few minutes after spraying.
  2. Use a sponge or cloth to wipe away the grease.
  3. Rinse and dry it off.

Tip # 4: Remove Old Paint:

It’s essential to remove any old paint before applying new paint to a surface. Use a paint stripper; paint strippers come in a gel and liquid forms.

Follow the instructions on the label for paint stripper application. In most cases, you’ll need to apply the stripper with a brush or roller and then wait for it to work its magic. After that, use a putty knife or scraper to remove the old paint. Finally, wipe down the area with a clean cloth to remove any residual stripper.

Tip # 5: Smooth Out using Sandpaper:

Use sandpaper to smooth out rough surfaces. It will help create a more even surface for painting and allow the paint to adhere better. Be sure to use the correct type of sandpaper for the job at hand.

For example, if you’re painting over a glossy surface, use finer-grit sandpaper so you don’t create too much texture. If you’re working with a wood surface, on the other hand, you’ll want to use coarser-grit sandpaper.


So, there you have it! The five easy tips to prep your surface for a flawless paint finish. By following these simple steps, you can avoid common painting mistakes and save yourself time and money.
