At CL Painting, we provide painting services in the Toronto area and collaborate with interior designers to ensure spaces that exude both style and quality. If you want to prepare your walls and ceiling the right way before painting, keep reading for our top tips.

1.⁠ ⁠Initial Inspection and Repairs:

Before starting any painting project, carefully examine your walls and ceilings for protruding screws or nails. If you plan to reuse them in the future, leave them in place; otherwise, remove them to avoid unsightly bumps on the surface.

If you encounter holes or imperfections caused by wear and tear, fill them with fast-drying plaster. Using a putty knife, apply an even layer of plaster to each hole and wait for it to dry. Then, smooth the surface with 200-grit sandpaper to ensure a seamless finish. Run your hand over the patched areas to confirm there are no thick lines or bumps that could become visible once the paint is applied.

2.⁠ ⁠General Sanding of the Surface:

With all patched areas taken care of, proceed to sand the entire area you plan to paint—this could be from floor to ceiling or from wall to wall if you’re working on the ceiling. Sanding removes grease, stuck-on dust, and other debris that may interfere with the primer or paint adhesion.

Make sure you reach every corner to achieve a uniform surface.

Sanding also prevents the paint from bubbling or peeling later on.

3.⁠ ⁠Deep Cleaning:

After sanding, use a clean cloth to wipe away loose dust. Next, thoroughly vacuum the workspace. This step is crucial because any remaining dust can circulate in the air and settle on freshly applied paint, causing a rough texture or other imperfections once it dries.

To avoid these issues:

Keep doors and windows closed to reduce drafts that move dust around.

Recheck corners and edges where debris tends to accumulate.

Make sure no other dusty tasks are happening in the same space.

4.⁠ ⁠Applying the Primer:

Once the surface is completely clean and dry, it’s time to apply primer. This product is essential because it:

Improves paint adhesion

Provides a uniform base, especially if you’re transitioning from a dark color to a light one or vice versa

Enhances paint durability, preventing stains and defects

At CL Painting, we recommend high-quality products to ensure a professional, long-lasting finish. For the interior designers we work with, a good primer makes it easier to apply vibrant colors or specialized finishes.

5.⁠ ⁠Benefits of Proper Preparation:

After thorough preparation, you’re far more likely to achieve an impeccable result. Key advantages include:

Less paint needed: A well-prepared surface typically requires fewer coats.

Smooth, consistent finish: It minimizes streaks, rough spots, and visible patches.

Increased durability: Your paint job remains in excellent condition for a longer time.

Enhanced presentation: Clients, guests, or collaborators will appreciate the quality workmanship.
