Executive Summary: Concrete Prep for Painting Houston
Concrete prep for painting in Houston cleans, degreases and dries patios, porches, walkways and garage floors so a primer, paint or sealer bonds to the surface.
The system is prep only: degreaser, surface wash, loose coating removal and a dry-time check. Most patios and porches take an estimated 2 to 6 hours with a 1 to 3 technician crew. Typical Houston-area pricing runs $60 to $100 for about 200 sq ft up to $320 to $500 for about 1,000 sq ft, with coating priced separately (estimates).
Damp concrete and rain push the schedule. Homes built before 1978 need lead paint testing before any scraping or sanding of old painted surfaces.

Stop Letting Fading & Damage Hurt Your Property Value
Paint peeling off concrete
Paint lets go when it was rolled over dirt, oil or an old sealer. A degrease and wash with a water bead test catches all three before primer.
Oil and tire stains
Oil pushes paint off from below. A degreaser with dwell time and a scrub lifts it before coating.
Mildew and algae
Shaded patios grow mildew that coatings will not stick to. We treat it, rinse it and let the slab dry. For washing alone, see Patio & Pool Deck Cleaning.
Schedule a Walkthrough
We look at the slab, test for old sealer, note oil stains and measure the area before writing a number. Coating is priced as its own line.
Our Process: Done Right the First Time

- 2Expert Prep & PaintingPlants and outlets get protected, then degreaser, wash and scraping. The slab dries before the coating crew starts.
- 3Final Walkthrough & Clean-UpYou walk the surface with the crew lead. Rinse water is directed away from beds, and debris leaves with us.
What to Expect: Your Project Timeline
| Stage | When | What Happens |
|---|---|---|
| Estimate & booking | Week before | Surface test, measurements, coating choice and written estimate |
| Prep day | Day 1 | Plants protected, degreaser, wash and loose coating removal |
| Paint application | After drying | Primer and coating, priced separately, once the slab is dry |
| Dry & walkthrough | Same visit | Walkthrough with the crew lead and surface check |
| Curing | Next days | Keep foot traffic and cars off the coating until it cures |
These are estimates. Rain or a shaded slab can add a day before coating.

Frequently Asked Questions
Concrete prep usually requires degreasing, pressure washing, removing loose coatings and letting the slab dry before any primer goes on. Oil and efflorescence keep paint from bonding. Most patios and porches take an estimated 2 to 6 hours to prep, plus drying time before coating.
We test a small area with water first. If it beads, an old sealer is still on the surface and has to come off before coating.
The short answer is about $60 to $500 to wash and prep a 200 to 1,000 sq ft patio before coating, based on typical Houston-area pricing. Area size, oil staining and loose coating removal move the number. Your written estimate after an on-site walkthrough sets the exact price.
In Houston, washing about 200 sq ft runs $60 to $100 and about 1,000 sq ft runs $320 to $500 (estimates). The coating itself is priced separately.
The short answer is at least a full dry day after washing in good weather, and longer after rain or in shade. Houston humidity slows drying, so we check the surface before coating. Paint over damp concrete blisters and peels, which wastes the prep and the coating.
Prep and coating are scheduled together so the slab is not left open to new dirt for days.
The short answer is no, not without degreasing first. Oil soaks into concrete and pushes paint off from below. We apply a degreaser, let it dwell, scrub and rinse, then check whether the stain still repels water, and deep stains may need more than one round before primer.
Driveway oil is the most common case. See Driveway Cleaning Services for washing on its own.
