Installation

Installing CertaTrim® properly is critical. For proper installation, using an appropriate PVC cement is critical especially for miter and scarf joints to help control expansion and contraction. We recommend Extreme PVC Trim Welder® or TrimTight™ cellular PVC cement. View installation guidelines before starting your project.
