Stained Concrete Flooring Questions

Not directly. The existing sealer must be removed by mechanical surface profiling first. Stain applied over a sealed surface cannot penetrate and will peel. The on-site assessment identifies what prep the slab needs before any stain is applied.

Yes. Stain follows the concrete surface, so cracks and repairs remain visible. Crack repair is completed before staining using a patch material chosen to accept color as closely as possible to the surrounding slab, which minimizes the contrast.

Without a sealer, the stained surface absorbs spills and stains permanently. In Phoenix, monsoon-season moisture can also work into an unsealed slab and cloud the color from below. The sealer is a required step, not an optional upgrade.

Cure time depends on the sealer product used and the ambient temperature. The written estimate states the exact cure period for your specific job. Walking on the floor before the sealer cures leaves permanent scuff marks.

Acid stain produces mottled, earthy tones that vary naturally across the slab. Water-based stain gives more even, predictable color and a wider palette. The installer reviews both options with you during the on-site assessment based on your slab condition and the look you want.

Yes, with a UV-stable sealer rated for exterior use. Phoenix UV exposure degrades sealers not formulated for outdoor conditions, so the sealer product selection matters. The estimate specifies the exterior-rated sealer and its expected maintenance interval.
