Step 1: Preparation

The first step in applying a sealant is to prepare the surface. Make sure you take time to clean the roof, use a hose, or a washer, and also, you need a push broom. The need for doing this is to make sure that you remove as much debris as you possibly can. This would give the roof a smooth surface before the sealant is applied. Once cleaning is complete, let it dry out before you begin.

Now that the roof has been washed and swept and is now free of debris, you need to cover all edges and seams with a patching cement using a paintbrush. You need to cover these areas because these areas are where most of the leaking happens. Make sure the patching cement dries off, for a period of one or two hours before you begin sealing.

Step 2: Application

Once the edges and cracks have been covered, and the roof has been cleaned, you can begin applying your sealant. Be sure to check the manufacturers guide if a primer is necessary. When spreading the coating on the roof, ensure that you use a long paint roller or a brush.

Do not try doing all the entire area at once, apply on 6 to 10 areas, and do this continuously until you end up working the whole roof. Make sure the coating is evenly spread with a thick coat.

Step 3: Finishing

Now that your sealant has been applied. You need to let it dry out and heal. The time it would take to dry completely will vary depending on the product you used, or the conditions of your environment. You need not worry about this since it is the responsibility of the manufacturer to pass this information to you.

Once your sealant is completely dried out, and you wish to color it, you can add a colored coating to it. An excellent roof sealant can help reduce damages to your home and add years to its life span.
