To paint a fence properly on a humid day with lasting results you will have to take some special precautions. Painting in humid weather is tricky because the humidity prevents the paint from sticking and drying properly. This becomes a bigger problem when you want to paint a metal object such as a surrounding metal fence. Paint doesn’t stick voluntarily to metal and it is much worse in humid conditions. This also applies to wooden fences but the problem caused here is of a slightly different nature. In the case of fences made out of wood, the problem is that because of the humid climate, once painted they will start to crack a bit if you don’t use an appropriate paint. To prevent the havoc that humid conditions can wreak on your painting project, follow these steps.

Step 1 - Pick a Warm Day

To achieve the best results, pick a warm day to start such a project, maybe even in summer. Warm air will neutralize any humidity found in the atmosphere helping the paint to dry quite quickly and effectively.

Step 2 - Clean the Area

The next step is to clean and clear the area surrounding your fence. This is not only for aesthetics purposes but even to eliminate humidity because certain plants and weeds attract the unwanted humidity and spreading it around the area of your wooden or metal fence. So make sure to clean the area properly.

Step 3 - Clean the Fence

For a wooden fence all you have to do is sandpaper it properly to get rid of old paint chips. For a metal fence, you have to use a coarse brush to remove all of the remaining old paint and oil. The latter can be done by using a water-based degreaser. While using the degreaser, make sure to follow the manufacturer’s instructions, to prevent harming yourself. Once done rinse everything with water.

Step 4 - Deal with Metal Fences

Metal fences require another step to completely remove the old rough paint. This can be achieved by using a common metal wire brush to remove the old paint chips and rust in such a way to eliminate the possibility of oxidization. You can skip this step if you bought a new galvanized metal fence.

Step 5 - Use Primer

You have to add a primer to both the wooden fence and the metal fence. The only difference is the type of primer to be used. A primer is very important because it creates a protective layer between the object and the paint eliminating the effects of weather. Leave the primer to dry properly. If needed, apply more than one coat.

Step 6 - Paint the Fence

Once the primer has dried you can now paint the fence. Use a paint designed for exterior use. Leave it to dry for at least two hours. If necessary, you can apply another coat.
