How to pave on an existing concrete patio

Updated November 21, 2016

Paving, also known as laying brick pavers, on an existing concrete patio, is not extremely difficult to do and can save you hundreds of dollars by doing it yourself. An existing concrete patio provides a solid foundation that will mean a more durable patio in the long run. Plan on at least a full weekend of work because you will need to allow time for certain building materials to dry. The good news is that once your patio is complete, the labour will be worth the effort.

Measure the length and width of your existing concrete patio and write down your measurements on a piece of paper.

Purchase pavers for your new patio. Bring your dimensions to the store that you are purchasing the stones or bricks from and they will tell you how many pavers you will need for your project. Choose from a wide variety of pavers stones and bricks, depending on your unique preferences. Natural stone pavers like slate and blue stone, for example, offer a very attractive and rustic look but come with a higher price tag than plain old brick pavers.

Mix the TSP according to the package instructions and apply a coat to the existing concrete surface. Allow the TSP to set for as long as the instructions say. Rinse off the surface thoroughly and let it dry before continuing.

Mix the mortar according to the directions on the package. Start in one corner and begin applying enough mortar to the concrete surface for three to four pavers at a time.

Apply the mortar to the surface with a layer that is 3/4-inch thick. Drag a trowel across the mortar to prepare the surface for the pavers.

Add the pavers one at a time on top of the mortar and set one 1/4-inch spacer between each of your pavers. Once all pavers have been installed, allow 24 hours for the mortar to dry.

Pour polymeric stabilising sand between all of the cracks of your pavers and spread the sand into the joints thoroughly.

Sweep and rinse off the surface and enjoy.
