Vertical jobs like this one take longer than horizontal projects. For these applications we have to modify our overlay materials to make it work correctly for vertical surfaces. These special overlay formulas are designed to go on thick without sagging, which makes it possible to apply stamps and other effects to vertical concrete overlays. We wouldn’t be applying a stamp this time, though; the business owners wanted a smooth surface for their new concrete fireplace hearth.
Part of the process involves not applying the overlay material all at once, instead, we put it on in 3-4 thinner coats. This method helps prevent sagging. We used tools such as rollers, rakes and trowels to spread the overlay mixture evenly across the concrete fireplace hearth. This created a smooth, level surface across the entire overlay.
