How Much Concrete Sealer Do I Need?
For a penetrating concrete sealer like Nanoprotect, coverage depends on three things: the square footage of your surface, how many coats you apply, and how porous the concrete is. Here are the rules of thumb most pros use.
| Surface Size | Typical Area | Recommended Size |
|---|---|---|
| Small patio / walkway | Up to 135 sq ft | 1 × 1 Gal Ready-to-Use |
| Average patio / 1-car driveway | 135–270 sq ft | Pack of 2 — 1 Gal |
| 2-car driveway | 400–600 sq ft | 2 × 33.9 fl oz Concentrate |
| Large driveway + walkway | 600–1,000 sq ft | 3 × 33.9 fl oz Concentrate |
| Pool deck / commercial | 1,000–1,500 sq ft | Pack of 4 — 33.9 fl oz Concentrate |
All sizes assume two coats — the recommended application for maximum stain and water repellency. For a single coat, double the area each bottle covers.

How to Measure Your Surface
- 1
Measure length × width
Use a tape measure or pacing (1 pace ≈ 3 ft). Multiply to get square footage.
- 2
Break odd shapes into rectangles
For L-shaped driveways or patios, calculate each rectangle and add them together.
- 3
Add 10–15% for porous surfaces
Older concrete, stamped concrete, and unsealed pavers absorb more sealer.
- 4
Pick two coats for best results
Two coats deliver maximum water and stain repellency. The calculator above defaults to two coats.
