Flagstone Sealing

New, unsealed, slate and flagstone is subject to surface wear and staining if not properly sealed and maintained. With proper sealing and ongoing maintenance, your flagstone or slate tiled areas will be more likely to have a long lasting, beautiful and durable appearance.

The sealer selection for slate & flagstone is generally based on the desired “finished” look you want and the degree of stain-resistance you need. There are two basic types of sealers: penetrating sealers and film forming sealers. Penetrating sealers soak into the surface leaving a natural look, and they make the surface resistant to water and stains. Film forming sealers actually form a coating or film on the surface of the stone. The film creates a barrier that holds out water and stains. The film may affect the look of the stone (adding a gloss or color enhancement).
