Overview

Sealing your bluestone properly is an important part of the installation process that should never be overlooked. To properly protect your new investment, you must seal the bluestones to prevent water damage from occurring after exposure to moisture. While sealing your bluestone may sound like a difficult process, it is actually quite simple with the help of proper instructions and guidelines.

Step 1

Mix one part of hydrochloric acid with 25 parts of water in a bucket away from the bluestone patio area. Exercise extreme caution by wearing gloves and a face mask when mixing the solution as the solution can cause serious damage to all parts of the human body. Test the solution on a small section of the patio to ensure that it does not damage the stones.

Step 2

Spread the solution evenly over the bluestone, using a watering can. Allow the solution to sit for approximately five minutes and then use a garden hose to saturate the area and remove all traces of the acid solution. The acid solution will thoroughly clean the area and prepare it for the sealing process. Allow three to four days for the stones to completely dry.

Step 3

Apply the sealant to the bluestone, using an industrial-size paintbrush. Apply even coats of the sealant so that all areas receive the same amount of exposure. To determine which brand and type of sealant is best for your product, consult with a local hardware store for the best options. For added protection, apply a second coat of sealant to the area after the first coat is completely dry.
