How to Maintain a Granite Patio

A granite patio is a durable and aesthetic choice for the exterior of any home. Use the following details to maintain your granite patio in an effective and undemanding manner.

Supplies Needed:

  • Granite sealer
  • Dishwasher soap
  • Water
  • Garden hose
  • Floor scrubber
  • Weed killer compound
  • Plastic spatula
  • 10% Hydrochloric acid solution
  • Dry cloth
  • De-greasing agent
  • Plastic bucket
  • De-icing salts

Step 1—Regular Cleaning of Granite Patio

Though granite has a largely impervious surface upon which grime or dirt is not easily impacted, regular cleaning is recommended. This ensures that the original luster of granite is maintained. You can do this with simple tools like a medium-pressure hose and a broom. Detritus can dull the surface of granite patios. Here, you need intensive scrubbing to remove the detritus. You can use a cleaning solution prepared from dishwasher soap and water and a floor scrubber for this. Repeatedly, rinse the granite surface to remove all traces of soap.

Step 2—Sealing Granite

Granite is among the most durable of natural stone choices. However, seams of a patio can develop cracks over a period. The surface can get tarnished due to external weather conditions. Thus, sealing outdoor granite surfaces is recommended. Sealers retailed specifically for sealing granite are easily available at hardware stores. You can use such products without any professional help. Most of these are retailed with detailed instructions and dedicated applicators. However, some sealers can affect the color of the granite surface, making it duller. To avoid such problems, you can use tinted or color-strengthened sealers.

Step 3—Removing Moss/Lichen/Algae

Patios close to drainage spots, residential pools or any other source of moisture are more vulnerable to algae or moss growth. The growth of lichen can be rampant if the patio is shaded. You can prepare a cleaning solution, using a retailed weed killer. Prepare the solution as per the manufacturer’s instructions. You can use a plastic spatula to edge out the moss or algae embedded within the joints or seams of the granite patio.

Step 4—Removing Rust Stains

You should dry the granite surface after cleaning it since stagnating water can stain the surface. This is particularly true for staining along the grout lines. Further, presence of furniture or any other item that is rusting can induce rust stains on the granite patio surface. Remove all such items and proceed with cleaning the rust stains. For this, get started by minimally wetting the stained surface. You need a 10% hydrochloric acid solution. Moisten a piece of dry cloth with this solution and wipe-away the stain. Properly rinse and dry the surface to remove all traces of the acid.

Step 5—Removing Oil Stains

Oil or grease can induce very hard-to-remove stains. Immediately remove the spilled oil using any kind of dry, absorbent material. You can use paper towels for this or old newspapers. Ensure that you don’t press upon the absorbent material, i.e. simply place them on the spilled oil, allowing the absorbent surface to soak-up the oil. Now, remove the absorbent material and get started with cleaning. For this you need a cleaning solution prepared with water and dishwasher soap. It is better to use lukewarm water. If this is unsuccessful in getting rid of the stain, you need an emulsifying/degreasing agent. This cleaner is usually retailed with a dedicated applicator or brush.

Step 6—Basic Seasonal Maintenance

Granite paved surfaces are sometimes treated with de-icing aids (retailed as de-icing salts). These are quite easy-to-apply and ensure that weather-induced damage to the granite surface is limited. This includes prevention against cracking induced by contraction/thawing caused by cold temperatures. These salts are usually applied when the paver is undergoing thawing. However, it is best to apply the de-icing agent according to the manufacturer’s recommendations.
