How to Maintain a Sandstone Paver Patio How to Maintain a Sandstone Paver Patio
A sandstone paver patio is stylistically pleasing and is easily installed. The sandstone paver patio can add value to the home. The one drawback to using sandstone instead of clay, slate or brick, is that sandstone is very easily damaged. If a sandstone paver patio is not properly maintained, the color can fade and the material itself can crumble and crack. The article below will explain how to clean and properly maintain a sandstone paver patio.
Step 1 – Cleaning the Patio
Remove everything that may be sitting on top of the patio. This includes plants, tables, chairs and the grill. The patio should be completely free and clear of anything. Then, sweep off the surface of the patio, to remove loose debris such as dirt, leaves and twigs. Once this initial sweeping is complete, hose down the patio, to do an initial cleaning. The sandstone must be completely dry prior to continuing, or you may damage the sandstone.
Step 2 – Heavy Dirt
A sandstone paver patio attracts dirt, due to the coarse texture of the sandstone. When you walk on the patio, you can leave mud behind in your wake. This mud will embed itself to the texture and a simple hosing down will not remove it. Mix warm water with several drops of detergent, and then gently scrub the patio. Allow the soap to rest for several minutes before hosing down the surface.
Step 3 – Remove Stains
There is not just one way to remove stains found on sandstone. For organic stains like mold and mildew, use hydrogen peroxide to remove it. For oil, use acetone and for grease stains, mound talc on top of the stain. Each of these methods with the exception of talc, are scrubbed on. After several minutes you can hose down the sandstone paver patio.
Step 4 – Finishing Joints
When a patio is being built out of sandstone, sand is used as a substitute for concrete or grout. The space between each sandstone paver should be touched up yearly. Pour sand on top of the patio and brush it over the stones and between the joints. Fill the joints up as much as possible and then wet the patio down and apply more sand. Once the sand dries it hardens like concrete.
Step 5 – Seal the Sandstone
Sealing the sandstone paver patio, is very crucial to maintaining it over a long period of time. Choose a sealer that is safe for sandstone, and then apply it to the patio using a standard paintbrush. When you apply the sealer, make sure that you do so in a very thin layer. It also should be applied with soft and slow strokes, so you do not leave behind streaks. Allow the sealer to dry for an entire day, and then apply a second coat.
