How to Lay Pavers on an Existing Concrete Patio

Patio pavers

An existing concrete patio offers an excellent, durable base for a paver patio, and can save you a lot of time and cost as it eliminates the need to pour a concrete slab. Laying the pavers yourself, rather than hiring someone to do it for you, can also save you a significant amount of money. Plan on spending at least a weekend working on your patio. Does this Spark an idea?
