What Goes Into a Thorough Interior Paint Job
F&F Painting's own 12-step interior process, explained step by step for anyone about to repaint a room.

Hiring someone to paint the inside of your home is easy. Knowing what a genuinely thorough job looks like before you hire anyone is harder, because most of the work that separates a good paint job from a so-so one happens before a drop of finish color ever goes on the wall. F&F Painting Company has published their own interior process on their website, broken into twelve steps. Walking through it in plain English is a useful way to understand what you are actually paying for.
Primer first, then a hunt for imperfections
The first step in F&F's process is a coat of primer, specifically Fresh Start Benjamin Moore Latex, applied to every wall and ceiling. Primer gives the finish coat something even to hold onto, so colors, especially pale ones or anything with a lot of pigment, go on looking consistent instead of blotchy in spots. After priming comes fine preparation of the walls and ceilings using spotlights to find imperfections that regular room lighting hides completely. A raking light held low across a wall shows every dent, nail pop, and seam that flat overhead light will never reveal. Where trim meets drywall, this stage also includes light spacing and floating at larger voids, so the lines where one surface meets another stay straight once the room is finished.
Filling, sanding, and a harder coat for trim
Nail holes and joints in casings, crowns, baseboards, wainscoting, and any specialty trim get filled with wood filler and Bondo, and cabinetry gets the same treatment when it's part of the job. All of that trim, cabinetry, and millwork is then sanded with fine grit sandpaper before any finish paint touches it. This step gets skipped more often than homeowners realize, and it's one of the most common reasons trim paint ends up looking rough or shows every brush stroke a year later. Once sanding is done, one coat of Benjamin Moore Oil Enamel Underbody goes onto the trim, cabinetry, and millwork. Trim gets handled, bumped, and wiped down far more than a wall ever does, so it needs a harder, more durable coating underneath the finish than a flat wall paint would provide.
A clean surface before the finish coats go on
Dust ruins a smooth finish, so the process calls for a full cleaning of every area before finish coats begin. On the day the finish coats actually start, all trims, cabinetry, and millwork get wiped down with denatured alcohol specifically to remove any surface dust that settled since the cleaning. Caulking goes onto all trims at this point too, closing the small gaps that would otherwise trap shadows and grime under the new paint. Then come the two finish coats, using either Benjamin Moore Regal Flat or Sherwin-Williams paint for walls and ceilings, with every surface inspected, sanded, and wiped clean between the first coat and the second. That inspection between coats is where small flaws get caught and fixed before a second layer of paint locks them in for good.
Protecting everything that's already finished
A lot of what makes an interior job go well happens before any paint is applied at all. F&F's process includes full protection of finished surfaces before work begins:
- Floors papered throughout the work area
- Windows taped
- Tile and stone surfaces covered
- Finished millwork, decorative hardware, and plumbing fixtures protected
This matters more in a home people are actually living in than it would in an empty building. Furniture usually stays in the room, kids and pets are still moving through the house, and daily routines keep going around the work. Careful protection of everything that's already finished is as much a part of a professional paint job as the painting itself.
Clean-up happens every day, not just at the end
The last step in the written process is a complete clean-up and removal of debris, and it happens daily rather than only once the whole project is done. For a family living in the house through a repaint, that daily reset is the difference between a project that feels manageable and one that turns the whole house into a construction site for weeks.
