The finish decides how a slab looks, feels underfoot and ages. Here is how the three most common residential finishes compare.
A broom finish is made by dragging a broom or brush lightly across the concrete after it has been floated and troweled. The result is a fine, ribbed texture. It is the standard outdoor finish for driveways, sidewalks and steps because it is simple, economical and provides grip.
Stamped concrete presses a pattern into the surface while the concrete is still workable. Mats imitate stone, slate, brick, wood or tile, and color is added through the mix, a powdered color hardener or a stain. A release agent keeps the stamps from sticking, and it must be washed off after the concrete has set.
Exposed aggregate removes the thin top layer of cement paste to reveal the stones in the mix. Contractors use a surface retarder and wash or brush the paste away, or occasionally another process, and the aggregate can be natural gravel, river rock or decorative stone.
This table gives a general picture. Individual results depend on the contractor, the mix, the climate and the sealer.
| Broom finish | Stamped | Exposed aggregate | |
|---|---|---|---|
| Look | Plain, understated | Highly customizable patterns and colors | Natural stone look |
| Traction | Good, a common choice for wet areas | Texture helps, but glossy sealer can be slick | Slip-resistant, rougher underfoot |
| Comfort barefoot | Comfortable | Depends on pattern depth | Can feel rough |
| Upkeep | Texture can hold dirt | Usually sealed and periodically resealed | Sealing is common to protect the surface |
| Best uses | Driveways, walks, steps | Patios, pool decks, entries | Driveways, patios, walkways |
| Repair | Easier to blend | Patches can show | Patches can show |
For driveways, broom finish is the practical default and the easiest to keep clean and repair. Exposed aggregate suits homeowners who want a more textured, natural look on a drive and are willing to maintain the sealer. Stamped driveways exist, but patterns that show wear or sealer wear can take more upkeep.
For patios, stamped concrete is popular because it can mimic stone or brick at the scale of a full slab. Exposed aggregate is a distinctive option for patios and pool surrounds, though the rougher texture is not for everyone. Broom finish makes sense for a utility patio or a modern, minimal look.
For walks and steps, texture and consistent edges matter more than looks. A broom finish on treads is hard to beat for traction, and decorative finishes should not sacrifice grip. Our sidewalks and steps page explains how we approach those spaces.
Plain broom-finished concrete does not strictly need a sealer, but sealing it protects against stains and, in cold climates, helps against water and salt. Stamped and colored concrete are normally sealed because the sealer deepens and protects the color. Film-forming sealers, such as acrylics, tend to need recoating periodically, and manufacturers give very different intervals, so follow the product label. Penetrating sealers, such as silane or siloxane types, leave a natural look.
Exposed aggregate is typically sealed to lock in the stones and to make cleaning easier. If an exposed aggregate surface is poorly done, stones can loosen over time, so ask a contractor to show you finished work and explain how the aggregate is bonded and protected.

Finish decisions are easier with specific questions. How will it feel underfoot, wet and dry? How does it handle snow shoveling or a plow blade? What sealer does it need, and how often will that be redone? Can a damaged section be repaired so the repair is hard to see? Does the contractor have examples several winters old, not just newly poured work?
Think about the household too. Barefoot kids and pets favor a smooth, comfortable surface, and a pool deck needs traction and heat comfort more than pattern. Where leaves or pine needles fall, light colors and deep textures show dirt and stains differently. Where the climate is harsh, practicality usually beats ornament.
You can also mix finishes. A broom-finished driveway with a stamped or exposed aggregate border, or a plain walkway leading to a decorative patio, gives you the look in the places people notice without the upkeep across the whole property. Mention the idea when you send a quote request, and we can sketch options.
Climate changes which finish performs best. In cold regions, a surface has to cope with snow shovels, plow blades and meltwater, and rougher textures can catch a shovel edge while smooth ones can polish and get slick. Deep stamp patterns hold water in low spots, which freezes, so ask how the pattern drains.
In hot sun, dark colors and dense surfaces can get uncomfortable underfoot, which matters on a pool deck or a patio used by kids and pets. Lighter colors and textured finishes tend to feel more comfortable, though the details vary with the product and the shade available.
Whatever the finish, the slab underneath still needs a sound base, correct thickness and proper curing. A decorative surface on a poor slab simply fails in a prettier way.
No finish makes concrete crack-proof. Decorative surfaces show repairs more than plain ones, because patching a stamped pattern or an exposed aggregate surface means recreating texture as well as filling a gap. The planning of joints, discussed in control joints explained, is especially important with decorative work.
Color also changes over time with sun, weather, wear and sealing. Ask for samples and, where you can, see projects that have been in place for several seasons. A sample board in good light is useful, but color and texture look different across a whole patio.

Broom finish is usually the most economical because it needs the least labor and no specialty materials. Stamped and exposed aggregate involve more steps and skills, but prices vary by area and contractor, so request quotes.
A broom finish is a reliable choice for traction, and exposed aggregate is rough and slip-resistant. Stamped surfaces vary with pattern, and a glossy sealer can reduce grip when wet.
It generally needs sealing and periodic resealing to keep color and resist stains. Without that, it can fade or wear unevenly.
It can, but the rough texture is hard on bare feet and edges are harder to finish cleanly. Many homeowners keep steps broom-finished and use exposed aggregate on the larger flat areas.
