How to get a wet concrete patio dry so that sealant can be applied?

My concrete patio is covered by a small roof and portions of it are always wet. I wanted to use a concrete sealant but directions say it needs to be dry. It won't dry and I have no idea why moisture is seeping up. Ideas on why or how to fix this?

    If it is wet all of the time then moisture is coming from somewhere and that needs to be solved. Is the patio a low point to surrounding areas? For instance if you are at the bottom of a hill it will hold water. If the concrete was not graded correctly than water can pool. If there wasn't gravel put under the concrete it can stay wet. There may be a broken water source under or near the patio?


    If it is damp because of heavy shade and a forest that can be different- an electric fan can help dry to out. Concrete needs to be very clean and very dry for a sealant to work. Then it needs to dry to cure.


    There are numerous reasons why water happens. Sealing it won't do a thing unless you remedy why the water is collecting. Most people can figure out why by giving a good look/see. Then decide what to do.

    Sealing it won't protect it from moisture, it's more to keep it clean

      Sorry!


      Concrete is porous, which means that it absorbs moisture. If this moisture doesn’t dry, it will create mold. Mold and mildew can form on concrete that is left wet for extended periods of time. This can cause a green discoloration to appear on your concrete surface. When you seal your concrete, you inhibit mold growth. This helps protect your concrete and keeps it looking better for longer.


      When exterior concrete is exposed to the elements, cracking, scaling, and other common concrete problems can occur. However, by sealing your concrete, you enhance the durability of the concrete, which can prevent damage. If you want to ensure that your concrete looks great and works properly, concrete sealer is a wise choice.


      An average concrete driveway can last 25-30 years, but if it suffers from discoloration or cracking, you may find that you need to replace it sooner than you planned. Concrete sealers can increase the concrete’s longevity. When you seal your concrete, you increase the chance that your concrete lasts for those 25-30 years.


      There are many things out there that can damage your concrete, so it’s important to protect it. Sealer can protect your concrete from oil spills and other stains, as well as the sun’s harmful UV rays. Sealer will also lock out moisture, so freezing and thawing will not damage it.

    Why seal concrete? Just clean it every couple of years with a power washer.
