C2 Guard for Wood: The Ultimate Deck Waterproofing Solution

Posted by Tommy Ekstrand on 06/03/2026

Your deck should be more than the paint-in-the-butt annual refinish project. It should be one of the most comfortable spaces in your world! It's an extension of your home, a place where memories are made, and gatherings are enjoyed(hopefully you like your guests). To ensure your deck remains a beautiful and functional part of your home for more than a few years, you likely already know that waterproofing is essential. The problem is that not all waterproofing solutions are created equal. Most require you to refinish or recoat every year! Not C2 Guard. This eco-friendly and non-toxic deck waterproofer is your answer.

Guard goes beyond surface protection

Remarkably Deep Penetration. Seriously.

Guard penetrates up to a centimeter into wood. The formula sets it apart from ANY other competition. Unlike many surface sealers that merely provide a protective layer on top of the wood, Guard goes deeper. It penetrates the wood's cellular structure, creating a flexible polymer shield from within. This remarkable deep penetration ensures that water is kept at bay, preventing common wood issues such as cracking, splitting, warping, and the damaging effects of mold and mildew.

Versatile Color Options

Your deck is a reflection of your style and personal taste. C2 Guard for Wood understands this, offering a palette of 16 beautiful colors (+clear) to choose from. Whether you prefer a natural wood look or want to add a pop of color to your outdoor space, we've got the perfect shade for you.

Ideal Pre-Treatment

The number one reason coatings fail outside is when water gets underneath. C2 Guard is not limited to protecting your deck; it's also an ideal pre-treatment for any wooden surfaces. Benches, trim, furniture, siding, shingles, you name it. If you're planning to apply paint or varnish to any of your wood surfaces, using C2 Guard as a pre-treatment is the smart choice to protect your investment. It lays the foundation for a long-lasting and flawless finish by ensuring that your wood is well-protected from moisture and the elements.
