Sealing Concrete and MaintenanceSealing concrete is the process of coating your concrete so it is protected from the elements. Sealing minimizes water from penetrating the concrete, blocks penetration of dirt, oil, grease, stains and chemicals, enriches the color and adds a nice sheen to the surface. Below is a picture of a half sealed patio.
How to Seal Concrete - These directions are given assuming that you are using a polyurethane sealer. If your concrete was freshly poured, wait until after the concrete has been broom-finished to apply a sealer. You may apply a sealer with a spray can if all areas of the concrete are reachable without stepping on it. Sealers give step by step directions and recommendations for sealing on the back of the label.
Sealing concrete is actually easier using a paint roller versus the spray can. There is less waste and sealer will not "pool up" as easily as with the spray can. Simply pour the sealer in painting pans and roll it on with painting rollers. Use the same process for spreading the sealer on as you would for painting a wall. Remember not to let the sealer pool up, so apply evenly. You may need to apply two applications if the surface is porous.
Reseal your concrete every 2 to 3 years, depending upon the traffic. For example, reseal a driveway every two years since it is driven upon. A patio may not need sealing for up to 4 years. After your concrete is cured and sealed, it is a good preventative step to caulk the control joints with a concrete joint sealant.
