I have a customer who had her deck sealed last year with a water based tinted sealer. She has asked me to re-touch it up again. She had major work done in the interior of her home and the deck was used as a storage and work area. The question; Can I re-touch this surface over the old sealer or should I re-clean and re-seal???
