[header] How to weatherproof a door [title] Use adhesive weatherproofing strips. [step] Before using adhesive weatherproofing products, thoroughly clean the area according to the directions on the weatherstrips. Once the area is dry, remove the backing of the adhesive strips a little at a time as you press them into place on the door jambs and along the edges of the doorframe. 
[substeps] Modern doors are usually designed with grooves along the sides and jambs that weatherstripping can be inserted into. Sometimes it can be difficult to apply an adhesive strip by yourself.
