Using a variety of methods not discussed here, some Cool customers at this point will add decorative accents to the coating. As an important final step, we recommend that you roll two coats of SealBack, Encore’s clear acrylic sealer over the entire job and allow it to dry. SealBack will bring out the depth and color of the coating and help keep the surface easy to maintain. SealBack is a nano-based sealer and provides an additional layer of protection against the weather for years to come.
