How to Seal Outdoor Granite Tiles

Granite tiles are a beautiful and durable addition to any outdoor space. However, it is important to seal them properly in order to protect them from the elements and keep them looking their best. Follow these steps to seal your outdoor granite tiles and ensure years of beauty and enjoyment.

1. Clean the tiles.

The first step is to clean the tiles thoroughly. This will remove any dirt, dust, or debris that could interfere with the sealant's adhesion. Use a mild detergent and a soft cloth or sponge to clean the tiles. Rinse the tiles thoroughly with clean water and allow them to dry completely before proceeding.

2. Etch the tiles.

Etching the tiles will help to create a rougher surface for the sealant to adhere to. This will help to ensure a longer-lasting seal. To etch the tiles, apply a solution of 1 part muriatic acid (hydrochloric acid) to 10 parts water to the tiles. Allow the solution to sit for a few minutes, then scrub the tiles with a stiff brush. Rinse the tiles thoroughly with clean water and allow them to dry completely before proceeding.

3. Apply the sealant.

Once the tiles are dry, you can begin applying the sealant. Apply the sealant in a thin, even coat using a brush or roller. Be sure to work the sealant into all of the joints between the tiles. Allow the sealant to dry for the amount of time specified on the product label.

4. Re-apply the sealant.

Once the first coat of sealant has dried, apply a second coat. This will help to ensure a longer-lasting seal. Allow the second coat of sealant to dry for the amount of time specified on the product label.

5. Maintain the seal.

To keep your outdoor granite tiles looking their best, it is important to maintain the seal. This means resealing the tiles every few years, or as needed. You can also clean the tiles regularly with a mild detergent and a soft cloth or sponge. Avoid using harsh chemicals or abrasive cleaners, as these can damage the tiles.
