Types of Paint Explained: Latex, Oil, Alkyd & Chalk

Latex acrylic (sometimes labeled "acrylic latex" or "100% acrylic") is the default for almost all interior wall painting. Water-based, dries in 1-2 hours, recoats in 2-4 hours, cleans up with soap and water, low odor, low VOCs. Sheens from flat to high-gloss. Suitable for drywall, plaster, previously-painted surfaces, and (with bonding primer) some non-traditional surfaces. The category includes everything from $25 Behr Premium Plus to $60 Sherwin-Williams Cashmere — quality scales with price. Use latex for walls, ceilings, and any interior trim where you do not need extra hardness.

Waterborne alkyd hybrids (Benjamin Moore Advance, Sherwin-Williams Emerald Urethane Trim Enamel, INSL-X Cabinet Coat) combine the easy water cleanup of latex with the hard self-leveling cure of old-school oil paint. They cure to a noticeably harder finish than regular latex, which matters for surfaces that get touched and scrubbed — cabinets, interior trim, doors, banisters. Slightly more expensive than premium latex ($45-95/gal), slightly slower drying. The right choice anywhere you would have used oil paint 20 years ago.

Traditional oil-based (alkyd) paint cures harder than any waterborne product, has the longest open time (good for brush leveling), and bonds aggressively to glossy or oily surfaces. But: 24-48 hour drying, mineral-spirit cleanup, high VOCs (some states have banned residential oil paint sales), and a strong solvent smell during application. Use oil only when (a) matching an existing oil-painted surface, (b) painting metal that needs maximum corrosion resistance, or (c) repainting historic woodwork where authenticity matters. For 95% of cases, the waterborne alkyd hybrid is the better choice.

Chalk paint (Annie Sloan, Rust-Oleum Chalked, Behr Chalk Decorative Paint) is a high-pigment matte paint designed for furniture refinishing. Its claim to fame: bonds to almost any surface (varnished wood, melamine, metal, even plastic) without sanding or priming, dries to a velvety matte finish, distresses easily for vintage looks. Limitations: not durable without a topcoat (wax or polyurethane), and the wax needs reapplication every 1-2 years. Use chalk paint on accent furniture (side tables, dressers, decorative chairs), NOT on dining tables, kitchen cabinets, or anything that takes daily abuse.

Milk paint is the ancestor of all modern paint — a mix of milk casein, lime, and earth pigments dating back centuries. It comes as a powder you mix with water before each use, has a 24-hour pot life, and produces a chalky natural finish with random color variations that read as "authentically antique." Use it ONLY for period-correct restoration of pre-1900 furniture or interiors. Modern chalk paints achieve a similar look with much easier application. Real milk paint requires more skill than any other paint type and is genuinely a niche product.

There are dozens of specialty paints; the four homeowners most commonly need: (1) Masonry paint — for brick, stucco, concrete; elastomeric formulas bridge hairline cracks. (2) Magnetic primer — iron-loaded primer that creates a magnetic surface beneath any topcoat (paint a kid's play wall, an office whiteboard). (3) Chalkboard paint — turn any surface into a writable chalkboard (kitchen menu wall, kids' room). (4) Epoxy floor coating — two-part chemistry for garage and basement floors; durable, chemically-resistant, but unforgiving of application mistakes. Use specialty paint only when the standard categories cannot achieve the function.
