Add PWR to your mortar mix to make it waterproof upon drying. PWR breathes by allowing internal moisture to escape while keeping rain and snow out. Just add one ounce of PWR to every 15 lbs. of dry mortar mixture. Mix it thoroughly with the dry ingredients, then add water. If you use PWR in your mix to tuckpoint a chimney, by the time you’re finished cleaning up, the mortar will be dry enough for you to spray Water-Base ChimneySaver on the bricks. No return trip necessary. This great product will not alter the surface color. No one but you and your customer will ever know it’s there doing its job day after day.
