Waterproofing your leather boots will maintain the quality and health of your boots. Without the precaution of waterproofing, leather can harden or crack. Not only does this maintain your boot's quality and your investment, but it allows you to brave the wet weather without regard to damage.
Prepare your leather boots for waterproofing. Remove all dust, dirt and staining with a cloth. Make sure you carefully wipe areas that include a seam or fold. The leather should be completely clean before application of waterproofing materials.
Find a clean cloth or a small clean brush for gel, wax or cream waterproofing products. Apply the waterproofing product evenly and thoroughly to the leather. Work the product over the boots to be sure that all exposed surfaces are coated and absorbing equally.
Wipe the excess gel, wax or cream waterproofing product from your leather boots. Except for the soles of the boots, the outer surface should be completely coated. Any drips or uneven areas of leather should be rubbed in and wiped down. Let the boots stand overnight to absorb.
Opt for a spray-on product and wipe down your leather boots in preparation for waterproofing. All dirt and dust should be gone and the leather should be completely clean. In a well ventilated area, hold the spray product half a foot away from the boots and in even strokes, apply the waterproofing spray.
Allow the coat of waterproofing spray to dry completely. Examine your boots and be on the lookout for areas where the application has been uneven or decide where you would like extra protection. The seams and folds of your boots are a good place to check. If needed, apply another even coat in the same way as the first. Allow the boots to dry overnight.
