A few weekends ago the weather was very pleasant, and I decided to waterproof four wooden gates that are on our property. My husband and I paid a visit to Home Depot and bought one gallon of Thompson's WaterSeal Advanced Maximum Strength on the advice of one of the salesclerks. This waterproofer is for use on decks and fences, brick patios, concrete driveways and other exterior surfaces. It gives maximum protection against water damage.
One thing this waterproofer isn't is easy to apply. I guess all waterproofers are like this, I can't say because this is the first time I've used such a product. It's of a very thin consistency and is milky white in color, though it blends into the wood when applied evenly. This is not a product you can put on with a roller, as it drips too much. You must use a paint brush. One coat application is all it takes to give you adequate coverage.
You are advised to test on a small area before actually applying. You must also apply only when no rain is expected for at least 48 hours, and the temperature must be above 50 degrees and not go below freezing for 24 hours after application.
There is an odor to this product, but since I was applying it outdoors, that was not a problem for me. Soap and water is all that is needed to clean up, but I experienced some tackiness on the brushes even after washing for about five minutes.
Time will tell as to whether this product really does protect the wood. It wasn't fun to apply, and I'm just relieved to have the job finished.
