2 Simple Steps to Protect Your Exterior Stonework
Doing this will extend the life of your exterior stone.
Exterior stone, including manufactured stone, can be damaged when it absorbs water and freezes. Applying a waterproofing sealer to the stone and mortar extends their life and reduces stone chipping and mortar cracks. A silane/siloxane product is best for this because it works without changing the color of your stone or mortar and allows the mortar to breathe. Buy a pump sprayer and silane/siloxane waterproofing product (about $30 to $65 per gallon at home centers and paint stores). To determine how much to buy, check the label for the products coverage and measure the square footage of your stonework.
Mask off the surrounding area (Photo with step 1), then use the pump sprayer to apply a first coat followed by a curtain coat (Photo with step 2).
1.Protect Trim and Plants
Mask off surfaces, such as trim boards, siding, house numbers and mailboxes. Cover plants and grass with tarps to prevent kill-off from the spray.
2. Apply in Two Steps
Spray the stonework with the first coat of waterproofer. Then immediately apply a liberal, wet-on-wet curtain coat so that the solution drips down 6 to 8 in. over the entire surface.
