If you are looking to put up a bird feeder or a mailbox post, or install or fix a fence post, this is an easy DIY product available online and most local hardware stores. It's called Sika Post Fix ( and Sika Canada Inc. and Sika). You mix it in the bag itself and pour it in. It expands to create an intimate bond with your post. Make sure you wear safety glasses and gloves for this one. | Sherry Holmes
