C2 Guard: Penetrating Protection for Wood & Masonry

Guard penetrates into the cellular structure and protects wood from the inside out. No cracking. No peeling. No flaking. Most sealers can't say that — because they never get past the surface.

Eco-friendly and non-toxic. Safe for kids, pets, plants, and aquatic life.

Protection That Becomes Part of the Wood

C2 Guard uses nanoparticle technology to penetrate past the surface and bond within the wood's cellular structure. The result is a flexible, breathable barrier that sheds water, resists mold and mildew, and prevents cracking, cupping, and warping — without ever peeling or flaking.

Most stains and sealers can't do this. They form a film on the surface that eventually cracks, traps moisture, and accelerates the damage it was supposed to prevent.

When it's time to refresh Guard, you clean and recoat. No sanding. No stripping. No starting over.

One System. Every Surface.

Driveways, Sidewalks & Masonry

Prevents water intrusion on concrete and brick. Makes shoveling easier — ice forms on top but won't bond to the surface.

16 STAIN COLORS. OR GO CLEAR.

Guard stain colors are formulated with the same attention to pigment and depth as C2's 496-color interior system. From warm honeys to coastal grays, each is designed to look rich on day one and age well over time. Colors are translucent — they'll look different on cedar than on pine, and on new wood versus weathered. That's the point.

FIVE STEPS. YEARS OF PROTECTION.

  1. Clean — Use C2 Wood Cleaner to remove dirt, mold, and residue.
  2. Dry — Let the surface dry. A bit of dampness is fine.
  3. Test — Drop water on the wood. If it soaks in, you're ready.
  4. Apply first coat — Brush or spray in manageable sections.
  5. Apply second coat wet-on-damp — While the first coat is still damp, apply the second. This is how Guard achieves full penetration.
