My Buying Guides on Gaco Deck Coatings
When I first started looking for a reliable deck coating, I quickly discovered how important it is to choose the right product. Gaco deck coatings stood out to me because of their reputation for durability and waterproofing. Here’s what I learned through my research and experience that might help you make a confident choice.
Why I Chose Gaco Deck Coatings
For me, the main reasons to go with Gaco were their excellent waterproofing capabilities and flexibility. Decks are exposed to all kinds of weather, and I needed something that could handle expansion and contraction without cracking. Gaco’s products are known for being elastic and long-lasting, which gave me peace of mind.
Types of Gaco Deck Coatings
Gaco offers several varieties depending on your deck’s needs:
- GacoFlex S20: I liked this one because it’s a water-based elastomeric coating that is easy to apply and dries quickly. It’s great for wood, concrete, and metal decks.
- GacoFlex 2300: This one is a two-part polyurethane coating, which is highly durable and chemical resistant. I considered this for areas with heavy foot traffic.
- GacoDeck 2300: Specifically formulated for decks, it provides excellent UV resistance and waterproofing.
Choosing the right type depends on your deck material and the level of protection you need. I recommend checking the product specs carefully.

- Waterproofing: Gaco’s coatings create a seamless, waterproof membrane. This is essential to prevent water damage and rot.
- Flexibility: I wanted a product that could expand and contract with temperature changes without cracking.
- UV Resistance: Since decks are exposed to sunlight, UV protection helps prevent fading and breakdown.
- Ease of Application: I was looking for coatings that I could apply myself with a roller or sprayer, without complicated mixing or special equipment.
- Durability: Longevity was important to me to avoid frequent re-coating.
My Application Tips
Applying Gaco deck coatings was straightforward but here are a few things I learned:
- Make sure your deck is clean and dry before starting. Remove any old paint or sealers.
- Follow the manufacturer’s instructions on temperature and humidity conditions for the best results.
