Weather-Sil - 5 Gallon Pail

Weather-Sil & Weather-Sil Extreme are penetrating silane sealers and water repellent for concrete driveways, side walks, garage floors and patios to prevent absorption of water and harmful de-icing salts. Weather-Sil chemically reacts and bonds to provide an extreme hydrophobic barrier that adds protection against harsh winter freeze/thaw cycles mixed with harmful de-icing salts. Over time, this mixture of freeze/thaw and winter de-icing salts will cause deterioration to concrete.
