Painting materials
The materials that decide whether a paint job lasts are the primer, the caulk and the patching compound - not the topcoat brand. Choose primer based on the problem you're solving (bare wood, stains, chalky surfaces, glossy surfaces), and sheen based on how much cleaning and light the surface gets. Higher sheen is more washable and more likely to show wall imperfections.
Sheen is a practical choice, not an aesthetic one. Flat and matte hide wall defects but scrub poorly. Eggshell and satin are the usual compromise for living spaces. Semi-gloss and gloss go on trim, doors and wet rooms because they clean up and shed moisture, and because trim is small enough that the extra shine reads as intentional.
Primer is not optional filler. Bare wood, patched drywall, stains, tannin-prone woods, chalky exteriors and slick previous finishes all need the right primer or the topcoat will not bond. If a bid says "two coats" with no primer on a surface that needs one, that is a corner being cut.
Caulk and patching are the invisible materials. Failing caulk at trim joints and siding seams is where water gets in, and it is the most common reason an exterior repaint looks bad in year two. Ask what gets re-caulked and whether old failed caulk is removed or just painted over.
Do not let a contractor invent product claims for you. If they tell you a coating carries a specific lifetime or warranty, ask for the manufacturer's written data sheet and warranty document. Coating warranties are usually material-only and full of conditions; the workmanship warranty from the contractor is the one that matters more.
Choosing painting materials
The judgement calls that decide the bill, before anyone quotes you.
- Pick sheen by room use, not by trend Kitchens, baths, hallways and kids' rooms take abuse. Ceilings and formal rooms don't.
- Ask what primer, where "Spot prime as needed" is vague. Ask which surfaces get primed and with what type - stain-blocking, bonding, or masonry.
- Get the exact product line in writing Brands sell budget, mid and premium lines under the same name. The line matters more than the brand.
- Don't buy paint yourself to save money You lose the contractor's pricing and often their workmanship warranty, and you own any color or product mistake.
- Old paint may be regulated waste Disposal rules for leftover paint vary by state, and many states run PaintCare drop-off programs. Ask your contractor how they dispose of waste, especially on pre-1978 homes.
