Interior Trim Preparation in Northern Kentucky, Cincinnati & Southeast Indiana
We are not just a painting company — we are your personal painter.
Great trim paint starts before the first coat. If your baseboards are rough, your seams are open, or old brush marks keep showing through, the real fix is trim preparation. My Personal Painter provides interior trim preparation—caulking, filling, sanding, and priming—so your trim paint looks smooth, your lines look crisp, and the finish holds up in real-life use.

Paint-Ready Trim Prep for Baseboards, Casing, and Doors
When homeowners search for trim prep before painting, they usually want one outcome: trim that looks clean and finished—not bumpy, cracked, or patched. We prep interior trim so the final paint lays down evenly and the details look sharp.
Interior trim areas we commonly prep
Baseboards and shoe molding
Door casing and window trim
Crown molding and decorative trim (scope-based)
Chair rail and wainscoting trim details (scope-based)
Interior doors and door frames (when included)
Built-ins and trim transitions (scope-based)
Common trim problems prep can correct
Open seams and visible gaps
Rough wood grain or raised edges
Nail holes and fastener marks
Old paint ridges and brush marks
Caulk failures and cracked joints
Stains or tannin bleed risk on certain woods

Caulking and Seam Work That Creates Cleaner Trim Lines
Many “messy trim” issues are actually seam issues. Proper caulking closes small gaps and gives your trim a more seamless look—especially where trim meets walls, window frames, and door frames.
Caulking steps we may include during trim prep
Re-caulking failed seams and cracked joints
Smoothing lines at baseboards and casing transitions
Gap correction where trim meets wall surfaces
Clean application that avoids heavy caulk buildup
Planning for movement points where cracking is likely
We keep caulk work controlled so the final line looks clean—not wavy or overbuilt.
Sanding, De-Glossing, and Surface Repairs for Trim That Paints Smoothly
If trim has old enamel paint, glossy finishes, or visible brush texture, sanding and de-glossing is often the difference between “okay” and “wow.” We prep the surface so primer and paint bond correctly and the new finish looks more uniform.
Surface prep steps we may include
Light sanding to smooth ridges and rough spots
De-glossing where adhesion is a concern
Filling nail holes and small dents for a cleaner painted finish
Feathering edges around chips and repairs
Smoothing profiles without damaging detail
Dust control and cleanup planning during sanding
If your trim is chipping or peeling, we’ll address the underlying cause so the new finish doesn’t fail early.
Priming and Stain Blocking for Trim That Paints More Evenly
Primer is not always optional—especially on raw wood, repaired sections, stained areas, or trim that has had adhesion issues. We plan primer and stain blocking so your paint sheen and color look consistent.
Primer decisions we help with
Primer needs for raw wood or new trim
Adhesion primer planning for glossy surfaces
Stain blocking for tannins, water marks, or old bleed-through
Spot priming vs full priming based on condition
Paint system planning for durability on high-touch trim
We’ll explain the “why” behind primer choices so you know what’s being done and what it prevents.
Interior Trim Prep Cost Factors and What Impacts Your Estimate
Trim prep pricing depends on how much smoothing, repair, and primer planning is needed—not just “how many rooms.” During your estimate, we’ll confirm which trim is included and what level of finish you want.

Condition of existing trim (chips, ridges, failures)
Amount of caulking and seam repair required
Sanding complexity (profiles, detail trim, glossy enamel)
Repair volume (holes, dents, patches, edge damage)
Primer and stain-blocking requirements
Access needs (stairs, high trim, tight areas)
Whether trim painting is included in the same project
