Sand Finishes / Acid Washed
For a lightly etched concrete surface that exposes only the sand fines of the concrete matrix Sand Finishes & Acid Washed Finishes can be the perfect solution. Natural gray concrete and soft hued tan colors are both effective in giving background coloration to the final look. Saw cut block pattern can be added to create precast and block paver effects.
Initially the concrete is placed into the forms using conventional pouring methods. Once placed and after the concrete has been finished to the proper stage special retardants are applied to etch away a thin film of the surface. After a curing period the surface is scrubbed with machinery to remove and expose only the sand matrix of the mix. The process gives a clean, formal and stylish effect to driveways, patios, sidewalks and pool decks and complements a variety of architectural styles.
