About Salt Finish Concrete Surfaces
Salt finish concrete creates a distinctive textured surface by pressing rock salt into fresh concrete and washing it away after curing. The resulting pitted texture provides moderate slip resistance and a unique aesthetic popular for pool decks, patios, and pedestrian areas.
The salt finish process requires careful timing. Salt is broadcast onto fresh concrete after initial finishing, rolled or pressed into the surface, and later washed away to reveal the characteristic pitted texture. The texture depth depends on salt size and application pressure.
Commercial applications include pool areas, outdoor dining, pedestrian plazas, and decorative bands within larger paved areas. The texture provides visual interest and moderate slip resistance without the aggressive texture of heavy broom finish.
Salt finish is often combined with integral color or surface stains for colored textured surfaces. The pitted surface accepts stain differently than smooth concrete, creating additional visual effects.

Frequently Asked Questions
How slip-resistant is salt finish concrete?
Salt finish provides moderate slip resistance, better than smooth troweled concrete but less aggressive than heavy broom finish. It is appropriate for pool decks and pedestrian areas where barefoot comfort matters along with slip resistance.
How deep is the texture on salt finish concrete?
Texture depth varies from 1/16 to 3/16 inch depending on salt crystal size and application pressure. Deeper texture provides more slip resistance but may be harder to clean. We adjust technique to achieve specified texture.
Can salt finish be combined with color?
Yes. Integral color or surface-applied color hardener can be combined with salt finish. Surface staining after salt finish creates unique effects as stain collects differently in pitted areas.
Does salt finishing affect concrete durability?
Salt finishing creates surface pitting but does not affect overall concrete strength or durability. The finish wears at the same rate as the concrete. Sealing enhances appearance and ease of maintenance.
Is salt finish appropriate for freeze-thaw climates?
Salt finish can perform well in freeze-thaw conditions with proper air-entrained concrete and sealing. Water collecting in surface pits can freeze, so drainage away from the surface is important.
