Interior Painting Done Right: What Proper Prep Actually Looks Like
A great interior paint job is judged mostly by what you don't notice — no visible nail pops, no roller marks where a color changes, no faint stains bleeding back through weeks later. That result comes almost entirely from the prep work that happens before a single coat of paint goes on the wall. Here's what that actually involves.
Patching Small Defects
Every room accumulates small imperfections over time — nail holes from picture frames, minor dings and dents, hairline cracks around trim or corners, drywall seams that have opened slightly. Before painting begins, these get filled and sanded smooth. Skipping this step is one of the most common reasons a "fresh coat of paint" still looks tired: paint doesn't hide texture, it highlights it, especially under angled light. A properly patched and sanded wall is what actually gives a paint job its clean, finished look, not the paint itself.
Washing Walls Where It Matters
Not every wall needs to be washed before painting, but certain rooms absolutely do. Kitchens accumulate a fine layer of grease and cooking residue on walls and ceilings, even in areas that look clean to the eye. Bathrooms build up soap scum, moisture staining, and general grime, particularly around showers, tubs, and vanities. Painting directly over these contaminants is a recipe for poor adhesion — paint can look fine initially and then peel or fail early, because it never properly bonded to the surface. Washing these high-contamination areas with an appropriate cleaner before painting ensures the new coat actually adheres and lasts as long as it should.
Protecting Floors Properly
Good prep isn't only about the walls — it's about protecting everything around them. Floors get covered with drop sheets or floor paper (or a combination of both, depending on the flooring and the job) before any painting starts. This isn't just a courtesy; it prevents drips, splatter, and foot traffic marks from becoming a cleanup problem, or worse, permanent damage to hardwood, tile, or carpet. Proper floor protection also lets the crew move efficiently through a space without constantly worrying about tracking paint, which ultimately makes for a cleaner, faster job overall.
Priming and Extra Coats for Colour Changes
One of the most overlooked parts of interior painting is what it actually takes to change from one color to another — especially when going from a dark color to a light one, or between very different color families. A single coat of new paint over a strongly contrasting existing color will often still show "ghosting" or shadowing of the old color underneath, no matter how good the paint is.
To get a clean, opaque, true-to-swatch result, this usually requires either:
A tinted primer coat formulated to block and neutralize the old color before the topcoat goes on, or
An additional coat of the new color beyond the standard two-coat application, to build enough film thickness for full, even coverage
Skipping this step to save time is one of the most common causes of customer dissatisfaction with paint jobs — the color looks "off" or patchy, not because of poor application, but because the underlying color was never properly neutralized.
Why We Like Cloverdale's Super 2 Ultra Hide
For interior work, we've been making increasing use of Cloverdale Super 2 Ultra Hide. As the name suggests, its standout feature is hide — its ability to achieve full, even coverage in fewer coats than many comparable products, even over moderately contrasting existing colors. That matters directly for the colour-change scenarios above: better hide means less reliance on an extra coat or specialty primer just to get rid of ghosting, which translates into a more efficient job without cutting any corners on the final result. It also lays down smoothly with good touch-up compatibility, which is a real benefit on interior walls that see everyday wear and occasional spot repairs down the road.
The Takeaway
The difference between an interior paint job that looks good on day one and one that still looks good a year later almost always comes down to prep: patched and sanded surfaces, properly washed walls in kitchens and bathrooms, protected floors, and the right approach to primer and coat count when colors change. Combined with a high-hiding product like Super 2 Ultra Hide, that prep work is what turns "we painted the room" into a finish that actually holds up.
