C2 Guard waterproofer and sealer protects from within.
Whereas other stains are formulated to sit on top of the wood as a thin, temporary layer, C2 Guard drops into the wood filling up its hollowed cell walls. After this absorption, a bond occurs forming a flexible polymer barrier that becomes part of the cellular structure. This barrier stops water intrusion completely. With C2 Guard, you can prevent the effects of mold and mildew, dry rot, cracking, peeling, and cupping of wood for up to 10 years.
We recommend C2 Guard for shingles, vertical wood siding, and fences. It’s also a fantastic wood protector to apply before paint.
👍This is Waters & Brown's top pick for preserving shingles and fences.
