Frequently Asked QuestionsCan Renew by QC surfaces be sealed? Yes. Sealers ensure long-lasting protection of stained surfaces. If sealing is desired, we recommend a QC-approved sealer system. QC Construction Products offers a range of high-end sealer systems for stained surfaces. These systems consist of two coats of a durable base coat sealer, followed by three coats of a special high-solids top coat maintenance sealer.
